Today, international travel has become more accessible than ever, and staying connected across borders has never been easier. Gone are the days of juggling physical SIM cards, worrying about high roaming charges, or hunting for local SIMs after landing. All thanks to the eSIM technology, a game-changer for seamless, hassle-free connectivity. 

But what is an eSIM? An eSIM (or embedded SIM) is a digital SIM technology embedded in the device’s hardware that can be activated remotely. This allows users to switch carriers, add new data plans, or update their connectivity settings without needing a physical SIM card. According to Grand View Research, the global eSIM market was valued at USD 8.07 billion in 2022 and is projected to grow at a compound annual growth rate (CAGR) of 7.9% from 2023 to 2030. 

In this guide, we will explore some of the top eSIM apps for international travel, and at the end, we will also share tips for choosing the best eSIM for your next adventure!

While ensuring seamless connectivity with an eSIM, why not simplify your visa application process, too? With Atlys, you can effortlessly apply for visas to 100+ destinations, making your international travel preparation even smoother.

Understanding the Difference: eSIM vs. Physical SIM

But before we cover the best eSIMs, let us understand the key differences between an eSIM and a physical or traditional SIM card. 

• Unlike a physical SIM card you insert into your device, an eSIM is embedded into your phone. You only need to download an eSIM profile from a provider directly onto your device.

• eSIMs allow you to store and switch between multiple plans on a single device. For example, you could use a local eSIM for Thailand while keeping your home number active on the same phone.

• You can activate an eSIM digitally anytime, anywhere, unlike a physical SIM card, which often requires a visit to a store or kiosk.

How to Choose the Best eSIM for International Travel

1. Global coverage and regional plan options

When selecting an eSIM, start by examining the coverage it offers. Especially if you are a frequent traveller, opt for providers with extensive global coverage to ensure reliable connectivity regardless of where you travel. 

For instance, Ubigi boasts coverage in over 200 destinations, making it an excellent choice for globe-trotters. Providers like Nomad and aloSIM also offer wide coverage, with regional plans that cater to specific areas like Europe or Asia. These regional options are often more cost-effective compared to global plans, providing better value for travellers focused on one or two regions.

2. Flexible data plans and pricing

Your travel plans and data usage needs vary, so look for eSIM providers offering flexible plans with clear pricing structures. Choose an eSIM with options such as daily, weekly, or monthly plans, depending on the duration of your trip. For example, Nomad provides local, regional, and global plans with prices starting at just ₹80 per GB for regional options. 

Transparency in pricing is equally important. Providers like aloSIM emphasise no hidden charges or roaming fees, ensuring you only pay for what you use.

3. Fair Usage Policy (FUP) on unlimited plans

Many eSIM providers advertise "unlimited" data plans, but most come with Fair Usage Policies (FUP). These policies cap high-speed data usage to a specific limit (e.g., 1GB per day), after which speeds are significantly reduced. While the slower speed still allows for basic internet access, this can be restrictive for users relying on high-speed connectivity for work or entertainment.

For example, Ubigi imposes a 1GB daily high-speed limit on its unlimited plans, with speeds resetting at midnight. If you require continuous high-speed internet, explore plans with higher data allowances or minimal restrictions, such as premium options from Nomad.

4. Customer support

Customer support is an essential consideration. While many providers, such as Nomad, offer 24/7 live chat and email assistance, others, like Ubigi, rely on customer support forms, which may be slower. You must carefully consider this point and evaluate the level of support you might need, particularly if you’re not tech-savvy.

5. Additional features

Look for value-added features that enhance convenience. For instance, Nomad and aloSIM support mobile hotspot functionality, allowing you to share data with multiple devices, which is especially useful for families or business travellers. Some providers, such as Saily, even offer web protection and ad blockers for added security during your travels.

6. Read online reviews

Goes without saying- check online reviews and ratings to gain insights from other users’ experiences. These reviews can provide valuable details about network reliability, ease of setup, customer support responsiveness, and any potential issues faced by other travellers. Providers like Nomad and aloSIM have strong ratings on platforms such as Trustpilot, with ratings of 4.4/5 and 4.2/5, respectively. However, user feedback can also highlight limitations, such as Ubigi’s limited customer support or Nomad’s occasional connectivity issues in certain regions. Reading these reviews can help you set realistic expectations and choose a provider that aligns with your travel needs.

Pro Tip: Look for recurring themes in reviews, both positive and negative. For instance, if multiple users praise the fast setup or complain about slow customer support, this can guide your decision. 

Conclusion

The eSIM providers discussed above, i.e., Nomad, aloSIM, Saily, Ubigi, ETravelSim, and Matrix, stand out as some of the best eSIM apps for international travellers. Each provider brings unique advantages, from extensive global coverage and flexible plans to innovative features like hotspot sharing and data calculators. 

Depending on your needs, whether you’re a business traveller needing constant connectivity or a leisure traveller looking for budget-friendly plans, there’s an eSIM tailored to your needs. With the right eSIM, you can focus on exploring new destinations, leaving behind the worries of connectivity and high roaming charges.
