eSIMs are the best option to stay connected when traveling internationally

Traveling internationally is more accessible and common than ever, whether for leisure, business, or remote work. But one of the biggest challenges that persists for globetrotters is staying connected. From expensive roaming charges to the hassle of swapping physical SIM cards, traditional mobile connectivity methods can be cumbersome. Fortunately, eSIM (embedded SIM) technology is changing the game. In this blog, we explore why eSIMs are the best option for international travelers who want a seamless, cost-effective, and hassle-free way to stay connected.

What is an eSIM?

An eSIM, or embedded SIM, is a digital version of the traditional SIM card. Instead of inserting a physical card into your phone, tablet, or smartwatch, an eSIM is built into the device’s hardware. It allows you to download and activate a cellular plan directly onto your device via QR code or an app, without needing to handle any physical component.

Convenience and Ease of Use

One of the biggest advantages of using an eSIM when traveling internationally is convenience. Before you even step on the plane, you can purchase and install a local or regional data plan right from your device. There’s no need to search for a SIM vendor at the airport or navigate a new country without data access.

Additionally, many providers offer apps that allow you to compare plans, activate service, and manage usage—all within minutes. If you’re visiting multiple countries, you can easily switch between different eSIM profiles depending on your location and needs. Download the OneSimCard eSIM app for Apple or Android:

Cost Savings

Roaming charges can quickly add up, especially if you’re using your home carrier’s international data plan. eSIMs help eliminate these costs by allowing you to select local carriers or specialized travel data providers with far more competitive pricing.

For example, instead of paying $10 to $15 per day in roaming fees, you could activate a local eSIM plan offering several gigabytes of data for a fraction of the cost. With so many providers competing in the eSIM market, you’re likely to find a plan that fits both your budget and usage requirements.

Instant Activation

eSIMs offer immediate connectivity. Most providers allow you to activate your plan instantly by scanning a QR code or downloading a profile from their app. There’s no waiting period, no paperwork, and no need to visit a store.

This instant activation is especially useful for frequent travelers or business professionals who can’t afford downtime. You can be online within minutes of landing, ready to check maps, book transportation, or communicate with colleagues and loved ones.

Multiple Profiles and Easy Switching

Unlike physical SIMs, which require you to physically remove and replace cards, eSIMs let you store multiple profiles on your device. You can easily switch between different carriers and plans through your phone’s settings.

This is particularly helpful for travelers who are visiting multiple countries on one trip. Instead of juggling several SIM cards, you can switch between different eSIM plans with just a few taps.

Better Security and Durability

Because there is no physical card involved, eSIMs are less prone to damage or loss. Travelers often swap SIMs in airports or cafes, increasing the risk of losing their home SIM or damaging the card slot. eSIMs eliminate this concern entirely.

Additionally, eSIM profiles are encrypted and can be protected with passwords or biometric authentication, adding a layer of security to your mobile connectivity.

Wide Device Compatibility

Most modern smartphones, including recent models from Apple, Samsung, and Google, support eSIM technology. Wearables like smartwatches and some tablets also support eSIMs, making it easier than ever to stay connected across all your devices.

If your device supports dual SIM functionality (physical + eSIM), you can keep your home SIM active for calls and texts while using a local eSIM for data. This ensures that you don’t miss important messages or calls while benefiting from affordable data services.

Environmentally Friendly

eSIMs are also a greener alternative to traditional SIM cards. By going digital, we reduce the production, shipping, and disposal of plastic SIM cards and packaging. With millions of travelers worldwide, this small shift can make a big environmental impact over time.

Flexibility for Remote Workers and Digital Nomads

Remote work has become more prevalent, and many professionals are choosing to live a location-independent lifestyle. For digital nomads, staying connected is not a luxury—it’s a necessity.

eSIMs provide the flexibility needed for this lifestyle. With the ability to switch networks and manage plans from anywhere, remote workers can ensure stable internet connections for video calls, file transfers, and collaboration tools, no matter where they are in the world.

Access to Local Networks

When you use an eSIM with an international data provider like OneSimCard, you get access to that carrier’s full network coverage and speeds. This is often better than roaming through your home provider, which might partner with local carriers but offer throttled speeds or limited bandwidth.

Using a local network through an eSIM generally results in faster data speeds, more reliable coverage, and lower latency—all of which are important when navigating new environments or relying on cloud-based apps.

Tips for Using eSIMs While Traveling

  • Check Device Compatibility: Ensure your phone or device supports eSIM functionality.
  • Compare Providers: Use comparison websites or apps to find the best plan for your destination.
  • Download in Advance: Activate your eSIM profile before leaving or while you still have access to Wi-Fi.
  • Monitor Data Usage: Keep track of your data usage to avoid unexpected overages.
  • Use Dual SIM if Available: If your device allows, keep your home SIM active for calls and use your eSIM for data.

Conclusion

Staying connected while traveling internationally no longer has to be expensive or inconvenient. eSIM technology offers a smarter, more flexible, and cost-effective solution for travelers. With instant activation, multiple plan options, and seamless switching between carriers, eSIMs have truly revolutionized how we connect abroad. Whether you’re a casual vacationer, a business traveler, or a full-time digital nomad, making the switch to eSIM can simplify your travel experience and keep you connected every step of the way. OneSimCard’s DataMax eSIM is a great choice if you are looking for low data rates in over 200+ global destinations!

Roaming eSIM: Say Bye to High Data Costs and Stay Linked Worldwide

Close up on a phone that includes e-SIM for travel.

Think of this: You go to a far-off place, thrilled to share your trip. You turn on your phone and boom! A flood of alerts warns you of huge roaming costs. Sound familiar? We all have felt that dread when we see how much it costs to stay connected abroad. But what if you could skip those high fees and stay online with ease? Meet the international eSIM, your best tool for world trips.

If you hate huge bills for data while traveling internationally, an eSIM is your way out. If you are on work trips, a globe-trotter, or a digital nomad on the move, this smart tech keeps you linked without draining your funds.

What is an eSIM?

A roaming eSIM, or built-in SIM, is a soft SIM that lets you use mobile data and make calls while you roam. No need for a tiny, removable, plastic SIM card. It’s built into your phone; you turn it on by loading a soft profile via download.

Here’s how it works: Instead of using your home carrier’s plan’s costly roaming links, a roaming eSIM hooks to local networks at your destination through agreements with world-wide carriers. This means you get strong data and calls at low rates.

The main advantage of a roaming eSIM over old costly roaming is the low cost and ease. Old roaming sticks to home carriers’ costs, which cost more and are not as free to change. A roaming eSIM gives you more internet and plans, often at much lower rates.

Why Choose an eSIM Over Old Plans?

  • Save Money on Calls and Data: This is the main draw. Roaming eSIMs have low rates, much less than your home plan charges.
  • Quick Start in Many Countries: No need to hunt for a local SIM. With a roaming eSIM, you can turn it on in a flash with a QR code, no matter where you are.
  • No Need to Swap SIMs: No more tiny trays or risk of lost SIMs. A roaming eSIM keeps your trip running smooth.

Key Perks of an eSIM

  • One Plan for Many Destinations: Some roaming eSIM companies give plans that work in more than one country, so you stay linked as you roam.
  • Pay-as-You-Go/Prepaid: Prepaid/Pay-As-You-Go plans allow you to control costs much easier than postpaid plans. With postpaid plans, you can come home with all of your fond memories only to be shocked at the end of the month with an enormous bill from your home carrier.
  • Change Networks with No Extra Cost: Many roaming eSIMs let you switch to the best network in each location with no fees.

How to Get and Start an eSIM

  • Pick a Roaming eSIM Company: Look up firms and check their plans, coverage, and costs. OneSimCard, for example, has fantastic, competitive rates for 200+ destinations.
  • Buy a Plan: Get the one that fits your trip and data needs, and make sure to read all the “fine print” regarding data speed throttling, covered countries, etc.
  • Turn It On: You get a QR code or code to scan. Use it to load and set up the eSIM.
  • Track Use: Most eSIM providers have apps or sites where you can check data use and tweak your plan. You can learn more about OneSimCard’s roaming eSIM App here: https://www.onesimcard.com/esim-app.

Best Uses for a Global eSIM

  • Work Trips Need Strong connections: If you must stay connected for calls, emails, and meets, a roaming eSIM is a must.
  • Trips to Many Lands: If you plan to go to more than one destination, a roaming eSIM lets you stay in touch with no stress of new SIMs.
  • Web Workers on the Move: If you work and travel, a roaming eSIM gives you strong and low-cost network connections.

Worldwide eSIM vs. Other Ways to Stay Connected

  • Local SIM vs. Roaming eSIM: A local SIM may cost less for one country but an international eSIM is best for trips to many destinations, and to keep for more than one trip.
  • Pocket WiFi vs. eSIM: A pocket WiFi means one more thing to carry and keep charged. A global eSIM is built into your phone for ease.
  • Best for Long Trips? An eSIM with a flexible plan is often the best and lowest-cost choice.

Wrap-Up

A roaming eSIM is a game-changer for those who roam. It cuts the stress of high costs and gives smooth, strong links where you go. With its ease, low cost, and flexible use, a roaming eSIM is a must for the new age of travel.

Get your roaming eSIM now and roam with no stress! Don’t let huge costs kill your trip memories. See the world with ease and stay connecte

d with a roaming eSIM. Your trip to smooth world-wide mobile device connection starts now!

Fixing Common International eSIM Failures

 

We’ve all been there. You buy an international eSIM for your trip and are excited to stay connected, it doesn’t work. No signal, no data, endless errors.

Why? The truth is, most eSIM issues aren’t random. They’re fixable. We’ve helped thousands troubleshoot these problems, and today, we’ll share the top reasons your international eSIM fails abroad.

From compatibility headaches to hidden network rules, we’ll break down exactly what’s going wrong. No tech jargon, no fluff. Let’s fix your eSIM struggles for good.

Your Phone Isn’t eSIM-Compatible


Many phones sold in the US or Europe still don’t support eSIMs. For example, older iPhone models (before XS) or budget Android devices won’t work. Check your phone’s settings: Go to “Cellular” > “Add Cellular Plan.”

If you don’t see an “Add eSIM” option, your phone can’t use an international eSIM. Always verify compatibility before buying. We’ve seen travelers waste $50 on eSIMs for unsupported devices. Don’t be that person.

You Bought the Wrong International eSIM Plan


Not all international eSIMs work everywhere. Say you’re planning to travel to Europe, so you buy a “Zone EU” plan, but you are still in your home country, USA for example. If you load your eSIM in your home country and then try to use your eSIM for data, the data plan you purchased (again, for EU) will not work. You will need to either put funds on the eSIM to use per MB data or purchase a small package that covers your home country so you can test.

Always check the fine print: Does it cover all the countries in which you are going to use the international eSIM? For example, a “30-country” plan might exclude popular spots like Croatia. Match the plan to your exact itinerary.

Are there speed caps? Reputable international eSIM providers like OneSimCard will list the data speeds for each country prominently. OneSimCard lists this on our Rates Page. We also list the networks we use in each country at the bottom of that page in the “View Roaming Network Details” section.

Your APN Settings Are Blocking Data


APN settings tell your phone how to connect to the internet. If these are wrong, even a working international eSIM fails. Go to Settings > Cellular > eSIM > APN. Often, the APN name auto-fills, but we’ve seen cases where it stays blank, or is set to the wrong APN.

Manually enter the APN your eSIM provider lists. For OneSimCard, you can find our APN settings for our SIM cards in our FAQs. Still stuck? Reset network settings. This fixes 80% of “no service” errors.

Data Roaming Isn’t Enabled

Another very common mistake travelers make when trying to use international eSIM cards is they don’t enable data roaming on their device. Don’t worry, though, because the fix is super simple!

We have created video tutorials demonstrating how to enable data roaming on iPhone and Android devices:

For iPhone devices, the video can be found HERE.

For Android devices, the video can be found HERE.

Your eSIM Activation Glitched Mid-Trip


International eSIMs sometimes deactivate if you switch networks too often. Imagine you’re on a train from France to Germany—your eSIM might “lock” to one tower and refuse to connect elsewhere.

Restart your phone. If that fails, delete the eSIM profile and reinstall it. However, there may be restrictions on how many times you can re-install an eSIM profile, so keep this as an “if all else fails” step. Pro tip: Activate your eSIM before leaving home (see note above about plans and where they work, though). Airport Wi-Fi is spotty, making activation risky.

Activation Nightmares in Foreign Airports

 

Ever tried activating an eSIM while jet-lagged? It’s a recipe for disaster. We’ve seen countless travelers stuck at airport info desks, frantically trying to get online.

The problem? Activation often requires a stable internet connection—which you don’t have yet! Here’s a quick fix: Download your eSIM before leaving home.

Then, activate it while still connected to your home network or airport Wi-Fi. Can’t do that? Look for free Wi-Fi spots in the arrival area.

Many airports now offer 15-30 minutes of free internet, perfect for a quick eSIM setup. Remember, patience is key.

Final Thoughts

International eSIMs should simplify travel, not stress you out. Most failures happen because we skip basics—checking phone compatibility, reading plan details, or testing APN settings.

Follow our fixes, and you’ll avoid 90% of issues. Still stuck? Contact our best-in-class USA based support immediately. Remember, even experts can face glitches.

The key is knowing how to pivot. Next trip, your international eSIM won’t suck. It’ll be your best travel buddy.

What is the Best Travel eSIM Card & Why?

Phone that includes eSIM.

We discussed eSIMs (embedded SIM cards) in a previous post. eSIMs aren’t all created equally, though. An “international eSIM card” is a bit of a misnomer. International / travel eSIMs are the of roaming SIMs as physical SIMs move into the past. The reason for the change is because device manufacturers save space on the device by replacing the physical SIM and it with eSIM technology. eSIMs are probably better called “SoftSIMs.” They are simply nothing more than a piece of software downloaded into devices enabled to understand this technology. What makes for the best travel eSIM then?

The world is becoming more and more data centric, so most eSIM providers only include data usage, They don’t bother to support voice or text. However, voice and text remain important for the international roaming SIM market. The growth of data centric applications like WhatsApp, Facetime, Telegram, Skype, etc. are changing the way providers deliver their services. You can communicate with friends and family, post messages and even place video calls with data only. This doesn’t work well for the international traveler, and is a major problem/flaw. It forces the international traveler to use another provider to place calls and send and receive SMS. This is because these roaming eSIMs don’t include a phone number. Without a phone number you can’t call your Uber driver, talk to your bank, call the restaurant that you are running late, etc.

This is where OneSimCard international eSIMs really stands out. Our international eSIMs support Data, Voice & Text messaging. Our SIMs include an EU based phone number and you can also choose alternate phone numbers (Personal Extra Numbers, or PENs). You can get in-country phone numbers in 70+ destinations with OneSimCard eSIMs.  You can set your alternate number as your caller ID so that your phone appears to be a local caller. What’s more is you can get a USA phone number that is a true mobile number. This USA mobile number allows you to receive 2FA verification messages required by banks, the IRS, and pretty much any other US company.

Usability is another important feature making an eSIM the best international eSIM.  eSIMs should be simple to install and have flexible plans. Flexibility is key as travel patterns. Meant for a single country, most eSIMs aren’t flexible because you can’t move between countries. OneSimCard eSIMs are designed to be used over and over for years, and in many different countries. Our plans are flexible; even in a single trip. We also offer 2 different eSIMs: our World eSIM for the greatest # of destinations, & our Asiania eSIM for use especially in Asia and Oceania.

The amount of support and applications available from the eSIM provider is the last factor for rating travel eSIM cards. OneSimCard is one of the only international eSIM providers with its own VOIP app (available in Google Play and Apple APP Store)for US and Canadian phone numbers to reduce the cost of Voice and Text services. OneSimCard also has eSIM apps in Apple App store and Google play. You can manage all aspects of your travel eSIM right in these apps. Multi-lingual customer service is also available by phone, email and online.  

You need to read the fine print and look at the reviews for eSIM service providers before you buy. There has been a rapid growth in this space, and COVID forced some closed. We have been in business for over 27 years, and have a 4.5 star rating with Shopper Approved with 2500+ reviews.

More information about our international roaming eSIM is available on our website: https://www.onesimcard.com/esim or simply scan this QR code. This page will help you further understand why the OneSimCard international eSIM for travel is the best option for your eSIM enabled phone when you are abroad. You can also reach out to us, and ask any questions that you may have. 

Wishing you safe travels!
