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.

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!

Discovering Slovenia: Trekking and Treats

Lake Bled and the Church of the Mother of God on the Lake
Lake Bled & Church of the Mother of God on the Lake

One of our favorite, just beginning-to-be-discovered, countries is Slovenia. Nestled between Italy to the West, Austria to the North, Croatia to the South and Hungry to the West, Slovenia offers many activities for everyone. Many travelers enjoy the great trekking and skiing offered. However, there is also a lot of history, culture and culinary offerings available. We think the best time to enjoy Slovenia is in early fall. This is when tourism is slowing and the crowds have dissipated from the hot spots, but there is still plenty to do.

An average day in Slovenia may include a morning hike in the Julian Alps or along the many beautiful lakes or rivers. Then a visit to a museum for an afternoon. Finally, a fantastic dinner to top off the day. Prices in Slovenia are still very reasonable, especially in the more rural villages. Even the larger cities like the capital, Ljubljana, have lots of shops, restaurants and activities at very reasonable prices

A magical town to spend a day or two is Bled. Its proximity to activities, the restaurants and sheer beauty of its surroundings make it a must see. You can take a walk around the lake (the Lake Bled Loop Trail) which is a 3.7 mile (6 km) easy hike. At the end of the hike, enjoy a walk through Castle Bled and enjoy some local food and drink in the courtyard while overlooking the iconic Church of the Mother of God on the Lake. If you are feeling a little more adventurous, you can take a short trip to the Triglav National Park. Slovenia’s only National Park is a sight to behold where you can challenge yourself a little more with the moderate to expert hiking and climbing offered in the Julian Alps.

Entrance to Hisa Franko Casa

Another must-do if you are a bit of a foodie, is to visit Hisa Franko Casa, located in Kobarid. When the Michelin Guide to Slovenia came out in 2019, Hisa Franko received 2 stars. It known for locally sourced, sustainable food. Hisa Franko is also listed as #21 of the top 50 restaurants in the world. (According to worlds50best.com) Ana Roš, the owner/Executive Chef, along with her husband Valter, operate this impressive restaurant which also has rooms to stay the night (highly recommended). There is also great hiking and a lot of WWI history in the town. We recommend the WWI museum in town and hiking nearby in old WWI bunkers and trenches.

All-in-all, Slovenia is a must visit country, especially for those with a love of nature, and delicious cuisine. But don’t worry…Slovenia is also a very well-connected country for technology as well. This makes sharing your gorgeous pictures of the hikes you take and food you eat easily shared when you use your OneSimCard International SIM. We suggest the Universal or eSIM World. This is because of the data packages available for Solvenia, like the 14 day 10,000MB EU data package for $57.00USD. So pack your bags, insert your roaming SIM card from OneSimCard, and enjoy the beauty of Slovenia!

Australia’s has reopened its borders to international travelers.

For the first time in nearly two years, Australia has reopened its borders to international travelers.  

More than 50 international flights reached the country on the opening day of February 21, 2022, including 27 touching down at Sydney, its largest city.

Tourism is one of Australia’s largest industries, valued at more than $55 billion and employing about five percent of the country’s workforce. However, the sector was hit hard after the country closed its borders in March 2020.

Australia, a former proponent of COVID’s suppression strategy, has moved away from frequent checks and lockdowns after reaching higher levels of vaccination. Skilled migrants, international students and backpackers have been allowed to fly to Australia since November as part of a reopening exercise.

More information about the vaccination requirements for entering Australia can be found on the official website.

Stay Connected

Both OneSimCard Universal and OneSimCard Expedition come with an optional free Australian number that can be extended or added at any time. You can also add an Australian phone number to any international eSIM. Multiple Discount data plans are also available in Australia.

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.

OneSimCard makes a convenient Europe sim card choice, as it offers low Data, Voice and SMS rates in Italy as well as many other European countries. You can also add a local phone number in Italy for even more authentic experience.  Multiple Discount data plans are available for your international SIM card.

If you have an eSIM capable device, you can download international eSIM straight from our website.

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.

Did You Know that Your travel SIM Can Power Hotspots?

Using OneSimCard for hotspot tethering
Using OneSimCard for hotspot data sharing

Very often we receive the question from customers asking if our travel SIM can be used in Hotspot devices and/or Smartphones to power the Mobile Hotspot feature. The answer is yes and yes!

What’s more is we allow you to share your connection with other devices at full speed for no extra charge. Many carriers throttle your connection when using the Mobile Hotspot on your smartphone and connecting other devices to it. These speeds can be as slow as 2G and 3G which virtually prevents streaming and many other apps like WhatsApp and Facetime from operating properly.

We never throttle your data. You can enable your Mobile Hotspot feature on your smartphone and allow all of the devices (think Tablet, Laptop, etc.) connected to the Hotspot to enjoy the same connection speed as your phone… up to full 4G LTE+.

Roaming in the Land of Fire and Ice: OneSimCard for Iceland.

  • Seljalandsfoss, Iceland

The Land of Fire and Ice is anything but ordinary. Technically a volcanic island, Iceland is famous for its unique landscape and stark beauty. Black volcanic rocks, glittering glaciers, erupting lava, bubbling hot springs, explosive geysers and many other natural wonders comprise numerous beautiful vistas.  

You can find something to do there year round, though summer is the most popular time to visit.  Warmer temperatures, less snow, more daylight and seasonal festivals draw the largest crowds. For most people the adventure begins after landing in the capital city of Reykjavík.

Reykjavík has a lot to offer including New Nordic cuisine, various museums and cultural sites.  You can even spot the Northern Lights from the city as well. However, many prefer to go out into more remote areas to enjoy Aurora Borealis without the interference of city lights, as well as explore other natural wonders the island has to offer.

Driving the Golden Circle is a popular day trip, especially for those short on time. The 186-mile route covers many natural landmarks including Þingvellir (Thingvellir) National Park with its tectonic fissures, Geysir and Strokkur geysers, as well as Gullfoss waterfall.

The Silfra Rift in a crack between the American and the Eurasian continents is one of the greatest dive sites on this planet. It boasts the world’s clearest waters with the visibility of 300+ feet.

For those with more time, the 828-mile Route 1 or the Ring Road around the island connects most of the inhabited parts of the country. Some of the most popular tourist attractions, such as the Seljalandsfoss and Skógafoss waterfalls, and Jökulsárlón glacier lagoon are also on or near the Ring Road.

Stay Connected

No matter how far your adventure takes you, having reliable means of communication is always a good idea. OneSimCard will provide you with all the connectivity you may need including Voice, SMS and Data with multiple Discount data plans in Iceland, throughout Europe and around the world. You can even add a local phone number in Iceland to your SIM card at any time.
