How to Choose the Right eSIM Plan: Pay-As-You-Go vs. Data Packages

Pay-As-You-Go vs Data Package infographic for eSIM

Choosing the right travel eSIM plan can make or break your international trip. Whether you’re a weekend wanderer, a digital nomad, or a frequent flyer, your connectivity needs will differ — and so will your costs.

The two main models travelers encounter are pay-as-you-go eSIMs and prepaid data packages. Each has advantages depending on how often and how much you use data while abroad. Let’s break them down so you can make an informed decision and save money on your next journey.


Understanding eSIM Plan Pricing Models

Before you can compare eSIM data plans, it’s important to understand the three main pricing structures used by global eSIM providers.

Pay-As-You-Go Explained

With a pay-as-you-go (PAYG) eSIM, you only pay for the data you actually use. There’s no upfront commitment or monthly fee — perfect if your data needs vary from one trip to another. You can top up at any time, and your balance simply decreases as you consume data.

Advantages:

  • Great for short trips or uncertain usage

  • No wasted data or expiration pressure

  • Ideal backup for emergencies or secondary devices

Considerations:

  • Typically higher per-GB cost than bulk data plans

  • Requires active monitoring of your balance, or OneSimCard’s convenient auto-recharge option.

Prepaid Data Packages

These data packages are sold in specific sizes — for example, 1GB, 5GB, or 10GB bundles that expire after a set time (usually 7, 14, or 30 days). You pay upfront, and the eSIM provides consistent data speeds and coverage.

Advantages:

  • Much Lower cost per GB

  • Predictable spending

  • Simple to manage for longer stays

Considerations:

  • Unused data expires

  • You may need to top up before the plan ends

Subscription-Based Models

Some providers now offer monthly eSIM subscriptions, charging a flat fee for ongoing data access in one or more regions. These appeal to frequent travelers, but they often come with fixed limits or auto-renewal requirements.


✈️ When Pay-As-You-Go eSIM Plan Makes Sense

For certain travelers, PAYG eSIMs are the smartest and most flexible option.

Occasional Travelers

If you take just a few international trips a year, it doesn’t make sense to commit to recurring plans. PAYG lets you stay connected during short vacations or weekend getaways without pre-paying for unused data.

Light Data Users

Some travelers rely mostly on hotel Wi-Fi and only need mobile data for maps or ride-hailing apps. PAYG plans are perfect here — you pay a little, use a little, and avoid waste.

Backup Connectivity

Even if you primarily rely on local SIM cards or Wi-Fi, having a PAYG eSIM installed ensures you’re never stranded without data when crossing borders or losing signal from your primary SIM.

In short, PAYG equals control — perfect for those who value flexibility over volume.


When a Data Package eSIM Plan Is Better

If you’re abroad frequently or use your phone as a mobile office, data packages are the more cost-effective solution.

Long-Term Travelers and Expats

For anyone staying abroad for weeks or months, prepaid eSIM packages offer stable pricing and dependable connectivity. You can easily renew the same plan or switch to another country’s bundle through your eSIM portal.

Business Travelers

Professionals need reliability and predictability. Data packages eliminate surprise top-ups, offering a steady stream of data for email, video calls, and navigation without running out mid-meeting.

Digital Nomads and Remote Workers

If you’re working from Lisbon one week and Bali the next, having a regional eSIM plan ensures coverage across multiple countries at a flat rate. This helps simplify billing and guarantees network consistency for streaming, uploading, and video conferencing.


How to Compare Costs Between eSIM Providers

With so many global eSIM brands competing for travelers’ attention, it’s worth learning how to do an eSIM pricing comparison properly.

Example Pricing Overview (1GB in Europe)

Provider 1GB Validity Approx. Cost
OneSimCard eSIM $4.50 14 days Multi-network access
Airalo $7.50 7 days Single-network coverage
Holafly $19 Unlimited High upfront cost
Nomad $8 30 days Regional
Ubigi $9 30 days Auto top-up required

(Pricing as of 2025 – subject to change)

Effective Cost per GB

To evaluate the true value, divide your plan cost by its duration and total data. For example, a 5GB / 30-day plan for $25 costs $5 per GB, which may outperform a cheaper plan that expires after 7 days.

Look beyond the sticker price. Factors like coverage, speed, and network redundancy matter just as much as cost.


Why OneSimCard Offers the Best Balance

Choosing between pay-as-you-go and data packages doesn’t have to be all or nothing — with OneSimCard, you can mix and match both.

  • Transparent pricing: No hidden fees, surcharges, or forced subscriptions.

  • OneSimVoIP app: Add optional voice and SMS to any eSIM data plan.

  • Customizable bundles: Buy what you need — whether it’s 500MB for a weekend or 20GB for a month-long project.

  • Global reliability: Multi-network access in 200+ countries ensures your connection never drops mid-journey.

With OneSimCard, you’re not tied to a single plan type — your eSIM adapts to your travel lifestyle.


Find the Right Plan for Your Trip

Whether you’re a casual vacationer or a full-time remote worker, understanding travel eSIM plans helps you stay connected without overspending.

Pay-as-you-go gives flexibility and control; data packages offer predictable value and stability. With OneSimCard, you get the best of both worlds — coverage, clarity, and cost efficiency.

Troubleshooting eSIM Issues While Abroad

Troubleshooting eSIMsReal-World Help for Travelers: Signal Loss, APN Setup & More. Troubleshooting eSIMs is simple!

When looking for international SIM cards, eSIMs have transformed international travel. Instead of juggling physical SIM cards or paying outrageous roaming fees, travelers can now activate data plans instantly with a quick QR scan. But even though eSIMs make staying connected easier, problems can still arise — especially when hopping between countries or networks. Whether you’re in Paris, Phuket, or Patagonia, here’s a practical guide to troubleshooting eSIM issues while abroad.


1. No Signal or “No Service” After Activation

This is the most common issue travelers face after installing an eSIM. You’ve scanned the QR code, it shows as “active,” but your phone still says “No Service.”

✅ Step-by-Step Fix:

  1. Turn Airplane Mode On and Off
    Wait 30 seconds and disable it — this forces your phone to rescan for available networks.

  2. Manually Select a Network

    • Go to Settings → Cellular → Network Selection (iPhone) or Settings → Connections → Mobile Networks → Network Operators (Android).

    • Toggle Automatic off, then pick one of the listed networks manually.

    • If you’re using a OneSimCard eSIM, try selecting one of our preferred roaming partners in your country.

  3. Restart Your Device
    Simple but effective — restarting clears temporary network glitches.

  4. Check if Data Roaming is On

    • For eSIMs, roaming must be enabled to access local partner networks abroad.

    • Navigate to Settings → Cellular → eSIM Plan → Data Roaming → On.

Pro Tip: In some regions, 2G or 3G networks are no longer supported. If your phone is older or set to connect automatically, switch to 4G/LTE only for better results.


⚙️ 2. Can’t Access Mobile Data (Even with Signal)

You have bars of signal but no internet — pages won’t load, maps can’t refresh, and apps spin endlessly. This typically means your APN (Access Point Name) isn’t set up correctly.

✅ Step-by-Step Fix:

  1. Check APN Settings

    • iPhone:
      Settings → Cellular → Your eSIM Plan → Cellular Data Network

    • Android:
      Settings → Mobile Network → Access Point Names

  2. Enter the Correct APN Information

    • For OneSimCard eSIM, the APN is typically: OSC
      (unless otherwise noted in your installation email).

    • Leave Username, Password, and Proxy fields blank.

  3. Restart Data Connection

    • Turn off Mobile Data for 10 seconds, then turn it back on.

    • Reopen your browser or try a speed test to confirm connectivity.

⚠️ Common Mistake: Many travelers forget to switch the “default data line” to their eSIM.
Go to Settings → Cellular Data → Select Your eSIM to ensure data routes through the correct plan.


3. eSIM Not Downloading or Activating

If your eSIM profile fails to download or install, it could be due to poor Wi-Fi, expired QR codes, or device compatibility.

✅ Step-by-Step Fix:

  1. Ensure You Have a Stable Wi-Fi Connection
    Activation requires internet access. If hotel Wi-Fi is unreliable, use a hotspot or café connection.

  2. Scan the QR Code Again

    • Go to Settings → Cellular → Add eSIM (or Mobile Plan).

    • Re-scan your OneSimCard QR code from your email or app.

    • If it’s expired, request a fresh activation link from support. This may require getting a new eSIM.

  3. Check Device Compatibility
    Only devices with built-in eSIM support will work. See our Complete eSIM Compatibility Guide for iPhone and Android for reference.

  4. Update Your Operating System
    Outdated software can block installation. Update to the latest version of iOS or Android before retrying.


4. eSIM Plan Doesn’t Appear in Settings

Sometimes, travelers install their eSIM successfully, but it doesn’t show under “Cellular Plans” or disappears after an update.

✅ Step-by-Step Fix:

  1. Restart Your Device — this often restores the display.

  2. Check Your Primary SIM Settings
    If you’re using a physical SIM simultaneously, ensure it isn’t set to “data only” while your eSIM is disabled.

  3. Reinstall the eSIM Profile

    • Delete the current profile under Settings → Cellular Plans → Remove eSIM

    • Re-scan the QR code to reinstall it fresh.

Pro Tip: Always save a backup of your eSIM QR code before traveling — many users delete their activation email by mistake!


5. Data Works in One Country but Not Another

Multi-country eSIMs (like OneSimCard’s) are designed for roaming, but occasionally, coverage may vary due to regional network preferences or restrictions.

✅ Step-by-Step Fix:

  1. Manually Switch Carriers

    • Turn off Automatic Network Selection.

    • Try another partner network in your current country (list provided in your OneSimCard app or welcome email).

  2. Enable Data Roaming
    Even if it worked before, moving across borders sometimes resets roaming permissions.

  3. Restart Device After Crossing Borders
    This refreshes your connection with the new country’s local network.

Tip for Frequent Travelers: Enable the OneSimCard eSIM Portal to monitor live connections, toggle networks remotely, and check data balances in real-time. Also, BE PATIENT!! Sometimes when you cross boarders it takes up to 15 minutes to find the right carrier(s)!


6. Battery Draining Faster Than Usual

Using dual SIMs (physical + eSIM) can slightly increase power usage because your phone pings two networks simultaneously.

✅ Step-by-Step Fix:

  • Turn off the SIM you’re not using.

  • Disable Background App Refresh for high-data apps like Maps or Instagram.

  • Use Low Power Mode while on the go.

⚙️ eSIMs themselves don’t drain extra battery — it’s the additional background network activity that does.


7. Calls or Texts Aren’t Working

If you can access data but can’t make calls or send SMS, the issue usually lies in your phone’s “Default Voice Line” settings or VoIP configuration.

✅ Step-by-Step Fix:

  1. Set Your eSIM as the Default Line for Calls
    Settings → Cellular → Default Voice Line → Choose eSIM

  2. Check Preferred Network Type
    Switch to “4G/VoLTE Preferred.” Some regions no longer support 3G voice networks.

  3. Use OneSimVoIP App for Calls
    If your plan is data-only, you can still make and receive calls with the OneSimVoIP app — available on iOS and Android.


8. When to Contact Support

If you’ve tried all the above steps and your eSIM still isn’t working:

  • Check your plan’s data balance or expiration date in your OneSimCard account.

  • Make sure your device IMEI isn’t carrier-locked.

  • Contact OneSimCard Support with the following info:

    • Device model and OS version

    • Country you’re in

    • Signal status and network name

Our team can run a live diagnostic and often resolve issues within minutes.

Travel Emergencies Solved by an eSIM

eSIM solving travel emergencies
Having an International eSIM Can Help with Many Emergencies

Even the most carefully planned trips can take unexpected turns. Flights get delayed, luggage disappears, and sometimes the worst happens when you’re far from home. What separates a minor inconvenience from a full-blown disaster often comes down to one thing: how quickly you can get connected.

This is where an international eSIM becomes a traveler’s secret weapon. With instant data access in over 200 countries, an eSIM from OneSimCard ensures you can navigate any emergency without missing a beat. Let’s look at some of the most common travel emergencies and how an eSIM can help you solve them on the spot.


1. Missed Connections and Flight Changes

Imagine this: your flight to Paris is delayed, causing you to miss your connecting flight to Rome. Hundreds of passengers are rushing to rebook at the airline counter, but you don’t have time to wait in line.

With a travel eSIM, you can:

  • Pull out your phone and rebook instantly through the airline’s app.

  • Use real-time flight trackers to find alternative routes.

  • Message your hotel in Rome to let them know you’ll be arriving late.

Instead of standing in a long queue, you’re already rebooked, sipping coffee at the gate, and adjusting your itinerary with zero stress.


Medical Emergencies2. Medical Emergencies Abroad

A sudden medical issue in a foreign country can be terrifying — especially if you can’t communicate quickly. Whether it’s food poisoning in Bangkok or a sprained ankle in Lisbon, time matters.

An international eSIM gives you the power to:

  • Instantly look up the nearest hospital or pharmacy.

  • Use translation apps to explain symptoms to doctors or pharmacists.

  • Call or message your insurance provider for guidance and coverage details.

  • Share your live location with travel companions or family at home.

Fast connectivity ensures that you’re not scrambling for Wi-Fi or relying on patchy roaming when you need urgent help.


Lost Credit Cards3. Lost or Stolen Credit Cards

You’ve just finished dinner in Barcelona when you realize your wallet — along with your credit cards — is missing. Panic sets in. But with an active eSIM, solutions are only a few taps away.

Here’s what you can do immediately:

  • Open your banking app and freeze your card to prevent unauthorized charges.

  • Use secure VoIP calls with OneSimCard’s app to contact your bank if you need assistance.

  • Pull up maps and ride-hailing apps to get safely back to your hotel.

  • Order an emergency replacement card delivered to your location.

Without data, you might be stuck hunting for public Wi-Fi while your stolen card racks up charges. With an eSIM, you take control instantly.


Lost in an unfamiliar city4. Lost in an Unfamiliar City

It’s easy to lose your bearings in a new city — especially at night or in a place where you don’t speak the language. A simple problem can quickly turn into a major catastrophe.

With a travel eSIM, getting back on track is simple:

  • Open maps and get step-by-step walking directions.

  • Use translation apps to ask for help or read signs.

  • Share your location with friends so they can meet you safely.

What could’ve been a frightening experience turns into a quick detour with minimal stress.


Extreme weather leading to travel disruptions5. Cancellations and Natural Disruptions

From rail strikes in Europe to sudden snowstorms in North America, travel plans can change in an instant. When services are canceled, being able to adapt fast is crucial.

With an eSIM:

  • You can rebook hotels or transportation from your phone.

  • Stay updated on real-time alerts from airlines, train operators, or local authorities.

  • Arrange alternative plans before most other travelers even know what’s happening.

Being the first to act can mean the difference between snagging the last hotel room or being stuck overnight in a terminal.


Keeping in Touch During Emergencies6. Keeping in Touch During Emergencies

Sometimes emergencies aren’t just about logistics — they’re about peace of mind. Whether you’re traveling alone or with family, staying connected is essential. It can literally be life and death.

An international eSIM allows you to:

  • Call or message loved ones back home instantly.

  • Share updates during crises (natural disasters, civil unrest, etc.).

  • Use secure messaging apps over data when SMS or voice networks are congested.

Your family knows you’re safe, and you feel supported even thousands of miles away.


Why OneSimCard eSIM Stands Out in Emergencies

Not all travel eSIMs are created equal. With OneSimCard eSIM, you get:

  • Coverage in 200+ countries and territories.

  • Instant activation with a quick QR code scan.

  • No contracts, no roaming shock — just prepaid, reliable data.

  • The option to use the OneSim VoIP app for affordable calls and texts.

  • Multi-network access in many countries, ensuring you’re not stuck on a weak carrier during an emergency.


Final Thoughts: Peace of Mind in Your Pocket

Travel is full of surprises — some magical, some stressful. But with an international eSIM, you’re never powerless in the face of emergencies. From rebooking flights to handling medical issues, protecting your finances, or simply finding your way back to safety, having instant global data can turn a crisis into a manageable inconvenience.

OneSimCard eSIM: travel smarter, safer, and always connected.

The Best Time to Visit Europe

Europe is a diverse and enchanting continent with a rich tapestry of cultures, histories, and landscapes. Deciding the best time to visit Europe depends largely on what you hope to experience. Each season offers unique experiences, and the optimal time to visit can vary by region and personal preference.

Spring (March to May)

Spring is a beautiful time to visit Europe. The weather begins to warm up, and flowers bloom, bringing life to parks and countryside. Popular destinations like Paris, Amsterdam, and London are less crowded compared to the peak summer months. Spring is ideal for exploring the outdoors, visiting gardens, and enjoying festivals like the Tulip Festival in the Netherlands or the cherry blossoms in Japan.

Summer (June to August)

Summer is the peak tourist season in Europe, and for good reason. The weather is warm, and there are numerous outdoor events, festivals, and activities. Coastal destinations such as the French Riviera, the Amalfi Coast in Italy, and the Greek Islands are at their best, offering pristine beaches and vibrant nightlife. However, be prepared for large crowds and higher prices.

Autumn (September to November)

Autumn is another excellent time to visit Europe. The weather is still pleasant, and the summer crowds have thinned out. The changing leaves create picturesque landscapes, particularly in places like Bavaria, the Loire Valley, and the Scottish Highlands. Autumn is also a fantastic time for wine enthusiasts, with many wine regions celebrating harvest festivals.

Winter (December to February)

Winter in Europe is magical, especially if you enjoy festive atmospheres and winter sports. Christmas markets in Germany, Austria, and the Czech Republic are a highlight, with charming stalls, festive lights, and seasonal treats. The Alps and Pyrenees offer world-class skiing and snowboarding. Cities like Prague, Vienna, and Salzburg are particularly enchanting with their historic architecture blanketed in snow.

Top 10 Things to Do in Europe

  1. Explore the Historic Cities of Europe Europe’s cities are treasure troves of history, culture, and architecture.

These institutions offer an opportunity to see masterpieces by artists such as Leonardo da Vinci, Rembrandt, and Michelangelo.
  3. Experience the Natural Wonders Europe’s natural landscapes are as diverse as its cultural heritage. The fjords of Norway, with their dramatic cliffs and serene waters, are breathtakingly beautiful. The Swiss Alps offer stunning vistas and are perfect for hiking and skiing. The Plitvice Lakes National Park in Croatia, with its cascading waterfalls and crystal-clear lakes, is a UNESCO World Heritage site that should not be missed.
  4. Indulge in Culinary Delights European cuisine is incredibly diverse and varies from country to country. In Italy, savor authentic pizza and pasta dishes, along with regional specialties like risotto and tiramisu. France is renowned for its gourmet food, from delicate pastries to fine wines and cheeses. Spain offers tapas, paella, and churros, while Belgium is famous for its waffles and chocolates. Don’t forget to try the local beverages, whether it’s German beer, Greek ouzo, or Portuguese port wine.
  5. Take a Scenic Train Ride Train travel in Europe is convenient and often offers some of the most scenic routes in the world. The Glacier Express in Switzerland takes you through the heart of the Alps, offering panoramic views of snow-capped mountains and picturesque villages. The West Highland Line in Scotland travels through rugged landscapes, past lochs and glens. The Cinque Terre Express in Italy connects the charming coastal villages of the Cinque Terre, providing stunning views of the Ligurian Sea.
  6. Relax on Beautiful Beaches Europe’s coastline is dotted with beautiful beaches that cater to all tastes. The Mediterranean coasts of Spain, Italy, and Greece boast sandy shores and crystal-clear waters, perfect for sunbathing and swimming. The Algarve in Portugal offers dramatic cliffs and hidden coves. The Baltic Sea beaches in Germany and Poland provide a different kind of coastal experience, with their unique landscapes and serene atmosphere.
  7. Discover the Castles and Palaces Europe is home to some of the most magnificent castles and palaces in the world. The Neuschwanstein Castle in Germany, with its fairy-tale appearance, inspired Disney’s Sleeping Beauty Castle. The Palace of Versailles in France is a symbol of absolute monarchy and is known for its opulent interiors and extensive gardens. In Scotland, Edinburgh Castle dominates the skyline and offers a glimpse into the country’s turbulent history.
  8. Enjoy Outdoor Adventures For outdoor enthusiasts, Europe offers a wide range of activities. In addition to skiing and snowboarding in the Alps, you can go hiking in the Scottish Highlands, kayaking in the fjords of Norway, or cycling along the Danube River. The diverse landscapes provide endless opportunities for adventure, whether you prefer mountains, forests, lakes, or rivers.
  9. Experience the Festivals and Events Europe hosts a myriad of festivals and events throughout the year. The Carnival of Venice, with its elaborate masks and costumes, is a spectacle to behold. Oktoberfest in Munich is the world’s largest beer festival, attracting millions of visitors. The Edinburgh Festival Fringe is the largest arts festival in the world, featuring thousands of performances across various genres. These events offer a unique insight into the local culture and traditions.

Situated in Northern Europe, Finland offers travelers a unique and captivating experience year-round. We delve into the wonders of Finland, from its enchanting landscapes and cultural treasures to its rich history and modern innovations.

Geography and Climate

Finland’s geography is defined by its numerous lakes, dense forests, and a long coastline that stretches along the Baltic Sea. It shares borders with Russia to the east, Sweden to the west, and Norway to the north. The country’s geography has a profound influence on its climate, with distinct seasons.

Discover the Majesty of Switzerland & Share with Your Switzerland SIM Card

Lauterbrunnen Alps
Lauterbrunnen Valley and Alps

Switzerland is known worldwide as one of the most beautiful places on earth. It is no wonder why with the towering Alps, lush green valleys, sapphire blue lakes, and varied cultures. Switzerland is an international destination for people with varied interests.

Introduction

Switzerland is also (and officially) known as the Swiss Confederation. It is made up of 26 Cantons, with Federal offices located in Bern. The population of Switzerland is ~8.2 million, with ~1/4 of the population being expats from other (mostly European) countries. This makes Switzerland the country with the most foreign population.

The climate of Switzerland is as varied as its population. There are three main geographies of Switzerland. The Alps, the Swiss Plateau, and the Jura mountains. Most of the population reside on the Plateau where all of the major cities are located. The climate is temperate, but ranges wildly depending on the locality. You will find year-round snow and glaciers in the mountains, but also palm trees in the southern plateau.

Regions

The Alps

The Alps are among the highest and most rugged mountains in the world. The highest peak is Dufourspitze. It is the second highest in Western Europe at 4,736m and is a challenge for any climber. They were formed by the collision of the African and European plates, and continue to grow.

Besides climbing, the Alps are home to a myriad of winter sports like skiing (alpine and cross-country), sledding, snowboarding, and summer sports like para-gliding and skydiving.  For the less active, the valleys in the Alps offer absolutely stunning vistas and easy hikes. One of the favorites is the Lauterbrunnen valley. Lauterbrunnen is home to the highest railroad in Europe (Jungfrau Railway), taking you to the peak of Jungfraujoch at 3,454m.

The Plateau

The Plateau is where you will find all of the major cities and beautiful lakes. With Zurich and Basel in the north, Bern centrally located and Geneva in the South, the Plateau is a collection of rolling hills, lakes, rivers and culinary delights like cheese and chocolate. (We recommend a trip to the picturesque town of Gruyere where the cheese is king and the views are stunning. kick back and enjoy some fondue!)

Lake Geneva is easily the most famous of the large lakes, but Lakes Zurich, Lucerne, and the twin lakes of Brienz & Thun are all equally beautiful. If you visit the twin lakes, stay in Interlaken and you will have easy access to both lakes! You can enjoy swimming, boating and hikes around the lakes.

The Jura

The Jura mountains aren’t as famous as the Alps, but that doesn’t mean they aren’t worth visiting. It is the demarcation between France and Switzerland. The Jura aren’t as tall and rugged as the Alps, but there is still lots of great opportunities for hiking, climbing, skiing, and cycling. This region is also known for its watchmaking industry. You can even be an “Apprentice for a day” and build your own watch!

The people of Switzerland are as varied as its geography. The landlocked country boarders France, Italy, Germany, Austria and Liechtenstien. This mixing of cultures creates a diversity in language as well as food, Local dishes are pulled from all of these countries and tend to align country to which that canton is closest. For example, one of our favorite lasagnas was enjoyed in the south, closer to Italy, while in Zurich we had fantastic bratwurst closer to Germany. This melding of cultures also shows in languages spoken, and traditional dress.

Getting Around

When travelling to Switzerland from international origina you will typically Fly into Geneva or Zurich. You may also find flights into Bern, but this is smaller international airport, and is typically used on a regional basis. Once you are in country, the train system is a fantastic way to get around. The trains run remarkably on schedule and are always clean and modern. You will find that the local trains are also used by schools to transport their students, so don’t be surprised to share the ride with lots of kids.

Speaking of trains, we recommend the GoldenPass Line for sightseeing. The GoldenPass trains are designed with huge windows  so you won’t miss a bit of scenery. There are 3 main lines: 1) Montreaux > Zweissimmen, 2) Zweissimmen > Interlaken Ost, & 3) Interlaken Ost > Lucerne. You can break up the trips stopping for a night or two in certain areas (we highly recommend the Lauterbrunnen Valley) and enjoy what these localities have to offer. You can also join an organized tour who will handle all of the bookings and activities along the way.

Summary

Switzerland is a truly majestic country with varied geography and cultures. There are many, many activities to enjoy year-round for people of all ages and physical abilities. We recommend travelling in June or July for the best weather. So grab your passport, pack your binoculars to make sure to see all of the stunning vistas and don’t forget your OneSimCard eSIM World or standard global roaming SIM card (the Switzerland SIM card we recommend is the Universal card) because you will want to stay connected to share all of your memories!

When in Rome, Roam as Savvy Travelers Do.

Rome, Italy
Rome, Italy

Although there is no real off-season in Rome, fall is known for decreased tourist crowds with plenty of sunshine for walking around. The challenge is to experience all the city has to offer. Here are a few picks of essential attractions to get you started.

Being over 2700 years old, the Eternal City combines ancient, baroque and modern eras, which can be both magnificent and overwhelming. A testament to the architectural skills of the ancient Romans – the Coliseum, Pantheon, and Roman Forum never cease to impress and are a must-see for anyone.

Many other historical, architectural and artistic treasures are scattered around the city. You can find some of them on the street in plain sight, others – in world-renowned museums and galleries like Borghese, MAXXI and Doria Pamphili to name a few.  

To round up your dolce vita experience remember to soak up some of the cultural scene. Eating out is one of Rome’s great pleasures.

Restaurants and open-air cafes line Rome’s numerous charming squares (piazzas). They offer plenty of opportunities to mingle with locals, or simply for people watching while enjoying local cuisine.

In Rome, no square seems to be complete without a fountain, each with its own artistic value and history. Trevi, Triton, La Barcaccia, the Four Rivers – the list of beautiful fountains (as well as squares) goes on and on. Legend has it that you can help your chances of returning to Rome by tossing a coin into the Trevi Fountain. 

When it comes to roaming connectivity, there is no need to toss coins at local mobile operator.

Many consider the city of Nice to be the capital of the French Riviera. From year-round sun and famous blue chairs to Art Deco architecture, museums and evolving restaurant scene, Nice, unlike its glitzier coastal rivals, has something to offer for every budget. The city is a popular destination for vacationers of all ages.

Castle Hill (Colline du Château) lets you enjoy a beautiful panorama of the Bay of Angels with the dramatic backdrop of deep blue waters of the Cote d’Azur. Fringed by the famous Promenade des Anglais it offers miles of the loveliest urban sea-front in Europe. Many events take place there including the annual Carnival and the Battle of Flowers. One can spend an entire vacation hanging out at the Prom (as the locals call it).

Museumgoers will enjoy the choice of over twenty museums and municipal galleries in addition to a large number of private contemporary art galleries and artists’ workshops. The most popular ones include the Museum of Modern & Contemporary Art, the Matisse and Chagall Museums.

Nice’s center is easily walkable. Enjoy the architecture of old city quarters, main square Place Massena, food and flower market Cours Saleya and the main shopping street Avenue Jean Medecin all within walking proximity. However, don’t fret if walking is not your thing – the city has a great public transport system or you can explore by bicycle.
