Best eSIM for International Travel (USA, Europe, Asia) in 2024

International data roaming is unapologetically expensive. The internet costs can pile up before you get a local SIM card from the nearest shop, SIM card vending machine, or phone plan kiosk at the airport. You can save a lot of money by getting the best eSIM for international travel.

eSIM services provide benefits beyond affordable internet access in the USA, Europe, and Asia. Many services also offer voice calls, texts, reward programs, and extra features (like a built-in VPN). Unlike physical SIMs, digital (eSIM) cards offer a convenient way to combine low-cost internet and call services on your phone. Besides, they’re future-proof in case phones begin to omit physical card slots entirely.

My colleagues and I tested over 20 services to find the best eSIM providers. I compared their services based on coverage, plans, apps, and general ease of use. Keep reading to learn what eSIM works best for your travel destination.

The Best eSIM Providers for International Travel in 2024

My team and I tested numerous providers to identify the best eSIMs for travelers. Through extensive tests, we assessed their value, ease of use, and key features. Here are the top eSIM service providers that stood out.

1. Saily - Best eSIM Overall

Developed by Nord Security and launched in 2024, Saily is an easy-to-use service with the best eSIM app for managing your account or accessing 24/7 live chat support. Installation takes only a few minutes and includes clear instructions for tracking data and topping up your plan.

Saily covers over 180 countries, including the US, the UK, India, Japan, Thailand, Turkey, Malaysia, and the United Arab Emirates (UAE). You can get regional and global coverage too. The eSIM also supports 5G connections and tethering, allowing you to share your data connection with other devices via hotspots.

Sadly, this eSIM is data-only — it doesn’t support voice calls or SMS messages at the moment. That said, you can still use apps like WhatsApp for messages and calls. Saily also offers affordable pricing; plans range from 7 days to a whole year and start at just $3.99. There are no hidden fees and you can get a refund within 30 days if you don’t activate your eSIM.

2. Airalo - Best for Local eSIMs

Airalo provides excellent local coverage and flexible plans. It offers various pricing options based on your chosen region, data, and the length of your stay. It’s a transparent option for travelers as there are no hidden fees or contracts.

This service provides consistent connections and reliable data speeds across multiple destinations, including local, regional, and global eSIM plans (covering 200+ countries). The installation process is quick, requiring only a QR code scan or code entry, and there’s 24/7 live chat support and email assistance.

Most Airalo plans do not include voice minutes or SMS, but it does provide some options with these features at a slightly higher price. Additionally, Airalo’s loyalty program (Airmoney) rewards you with cashback on every purchase.

3. Airhub - Best eSIM for Voice Calls and SMS

Airhub provides global eSIM solutions, covering over 190 countries with flexible data plans. You can choose from regional or country-specific packages and the service delivers reliable 4G LTE speeds. Some plans even offer 5G in specific countries (including Thailand). Most importantly, Airhub is one of the only eSIM options that supports unlimited voice minutes and texting.

The downside is that setup can be problematic, and the customer service isn’t very responsive or helpful. I encountered delays in receiving the QR code to set up my eSIM. Once it arrived though, installation was quick and the app interface was intuitive. Most plans are very affordable and include data-sharing options. Additionally, there’s a reliable 30-day money-back guarantee on all plans.

4. Tello - Best US eSIM for International Calls

While Tello only works in the US, all its eSIMs come with unlimited free calls and texts to 60+ countries. So you can easily stay in touch with home while traveling in the States. The “Build Your Own” setup also gives you control over your plan. You can customize your data and call allowances to save money. You can also cancel, downgrade, or upgrade at any time — without hidden fees.

Plans range from call-only to unlimited data and start at $5/month for 1GB. The unlimited data plans start at $25 and include 5G, as well as 5GB of hotspot tethering.

5. Ultra Mobile - Best US eSIM for International Roaming

Ultra Mobile is another US eSIM service. It’s a bit more expensive than Tello but all plans include free international calling to 90+ countries and international roaming in 210+ destinations. Plus, Ultra Mobile’s “Call Me Free” feature also lets your friends reach you from abroad without fees.

The network is backed by T-Mobile’s extensive 5G networks, designed to provide high speeds in the US. That said, I didn’t experience high speeds everywhere I traveled. In some States, I encountered dropped calls and messages not being sent. The money-back guarantee is also only available for 7 days. Still, the international roaming and call options make this a solid choice for travelers or expats living in the US.

What is an eSIM Service?

An eSIM is a digital, rewritable SIM card that’s integrated into your device. Unlike physical SIM (Subscriber Identity Module) cards, there’s no removable chip and you can use an eSIM to switch between mobile networks directly through your phone’s settings. Otherwise, digital cards provide the same capabilities as regular SIM cards, such as making calls, sending texts, and getting 2G/3G/4G/5G internet access.

An eSIM is a flexible alternative to traditional chips in phones and tablets with limited card slots. Many people use digital cards for international travel or access to affordable internet. As the Apple iPhone, Motorola Razr, Google Pixel, and other Android devices start moving toward eliminating physical SIM slots, eSIMs may be the future for all devices anyway.

eSIM plans usually come in 3 varieties:

• Global eSIM — These plans can be used anywhere in the world, making them perfect for international travel across multiple countries.
• Regional eSIM — Slightly more concentrated than global eSIMs, regional plans usually cover continents or specific areas, like Europe, Africa, Asia, or Latin America.
• Local eSIM — These eSIMs are for one country only. They’re usually less expensive, so they’re more economical if you’re only going to travel to one place.

Why Do I Need an eSIM for International Travel in 2024?

Using an eSIM offers several benefits over traditional SIM cards, especially if you want to use it for international travel.

• Avoid roaming costs. eSIM apps offer international data plans that help you avoid high roaming charges. These plans are often cheaper than local options.
• Remotely activate from anywhere. eSIM technology allows you to activate mobile plans directly from your phone, so you don't need to visit a store or buy a new SIM card each time you travel.
• Easy setup. You can activate an eSIM instantly through a QR code, a more traditional activation code, or an app. It only takes a few minutes to set up. Plus, some eSIM providers offer intuitive apps that let you easily adjust your plan. No more worrying that your SIM won’t turn up in the post before you travel.
• Increase your data security. eSIMs cannot be physically removed or cloned, reducing the risk of unauthorized access. This also makes your device easier to track if it gets lost or stolen.
• Use multiple eSIM cards. You can have different eSIMs for various needs, like one for business, one for personal use, and another for travel. This flexibility allows you to manage multiple numbers and data plans efficiently. It’s also more environmentally friendly than having multiple physical SIMs.
• Conveniently change plans. Unlike physical cards, you don’t need to swap out a chip whenever you want to change your plan. You also don’t need to worry about losing the chips you’re not currently using.

Step-By-Step Guide: How to Activate an eSIM Service on Any Device (Android, iPhone, iPad)

Most eSIM services provide instructions on how to activate the service. Here’s a step-by-step outline of how it usually goes:

1. Ensure compatibility

Check that your device supports eSIM services. Most post-2017 devices work with eSIMs. These include iPhone XS, iPhone XS Max, iPhone XR, or later. The easiest way is to Google your phone model with “eSIM compatibility”.

Here’s how to check if your iPhone or iPad supports eSIMs:

1. Go to Settings, select General, and tap About.
2. Scroll down to find the Carrier Lock section. If your device is unlocked, it will show No SIM restrictions. If not, you need to unlock your device first.
3. Scroll down to Available SIM and, if you have earlier iOS versions, find Digital SIM. If your phone works with eSIMs, it will show a 15-digit IMEI number.

Here’s how to check if your Android device supports eSIMs:

1. Go to Settings, select Connections (Network & Internet), and tap SIM manager (or eSIM cards).
2. Compatible devices will show an Add eSIM (Download a SIM instead) option. Alternatively, from Settings, go to About phone. Supported devices also have an option called IMEI (eSIM) or Embedded SIM.

Visit your phone's settings to check for compatibility

2. Register with an eSIM service

eSIM providers like Saily allow you to check your device's compatibility too

Choose an eSIM provider and plan based on your needs. Take into account features like country coverage, data limits, price, and data sharing (tethering).

It’s also a good idea to download a compatible eSIM app if your provider offers it. That way, you can simply follow the on-screen instructions for the installation.

Saily offers one of the best eSIM apps for iOS and Android

Then, sign up with a provider and pay for your plan. Some eSIMs don’t require registration or any personal information, and most accept a variety of payment methods including pre-paid card, Apple Pay, PayPal, or credit card.

Be sure to confirm whether your chosen plan auto renews

3. Add an eSIM plan in the settings

Configuration should be automatic. However, if your phone doesn’t set up your eSIM for any reason, just follow these simple steps:

For iOS and iPadOS:

1. From Settings, navigate to Mobile Service.
2. Tap Add eSIM. This should trigger the Set Up Mobile Service window to pop up.
3. Choose to Transfer From Nearby iPhone or Use QR Code.

For Android:

1. Navigate to Settings, click Connections, and tap SIM Manager.
2. Select Add eSIM or Add Mobile Plan.
3. If your provider isn’t on the list, select Other ways to connect to a mobile network.
4. Select Enter Activation Code, Scan Operator QR code, or Transfer SIM from another device.

Alternatively, you can input the eSIM activation code or transfer data from another device

To finish setting up, restart your device to apply the changes and new tariffs.

How to Choose the Best eSIM Carrier & Plan for International Travel

To determine the best eSIM provider, I considered the following factors. These are the key elements you should evaluate when choosing a service.

• Network. Check coverage for the country or state you’re visiting to avoid poor connectivity. Many eSIM providers offer global data plans for international travel, so you don’t need individual plans for each country.
• Pricing. Compare the cost of your provider (usually shown per GB). Remember to factor in the duration of your travel since eSIM providers usually offer different plan lengths, such as 7, 15, 30, and 60-day plans. Some providers also offer cashback or reward programs.
• Internet speeds. Providers may offer excellent speeds in some countries but mediocre performance in others. Check user reviews and speed tests to get a good idea of the performance you’re likely to get.
• Data limits. Evaluate your data needs based on activities like streaming, browsing, and communication. Some providers offer unlimited data or pay-as-you-go plans that can be more economical for heavy bandwidth users.
• Data sharing (tethering). Not all providers support tethering or mobile hotspots. If you need to tether other devices to your eSIM, ensure your chosen provider supports this and doesn’t throttle your connection when tethering is activated.
• Phone services. If you want to make international calls or send messages without using VoIP or online services, confirm that your eSIM provider offers call minutes, SMS, or MMS. Otherwise, you’re limited to apps like WhatsApp or Telegram.
• Customer support. Reliable customer support is important for getting help with any issues or questions you might have. Providers that offer 24/7 support are useful since you can get answers at any time — no matter what time zone you find yourself in.

FAQs on eSIMs for International Travel

Does my phone support eSIM providers?

Most post-2017 smartphones are compatible with eSIM services. Your phone must also be factory-unlocked to use a digital (eSIM) card. Check your phone or tablet settings to ensure compatibility. You can also contact your original provider if necessary.

Do I need to get a different eSIM for each country I visit?

It depends on your plan. Some providers do require you to purchase a plan for separate countries. Meanwhile, many eSIM services have regional or global plans that can be used in multiple countries.

Does an eSIM only work on unblocked iPhone and Android devices?

Yes, eSIMs only work on unblocked devices, including most phones after 2017 (iPhone X and newer). You can easily check compatibility with eSIMs in your settings. If your phone is locked to a provider, you can request a Network Unlock Code (NUC) from your provider once your contract ends.

Should I install an eSIM before traveling?

It’s better to install and customize the eSIM before arriving in another country to avoid high roaming charges. Make sure to compare different eSIM plans based on your needs.

Can I call with an eSIM internationally?

Yes, some eSIM services offer calls and SMS. Airhub is one provider that offers voice minutes for traditional calls. That said, you can always use VoIP services and messaging apps if your provider doesn’t offer this functionality.

Are there any risks to using an eSIM?

Yes, eSIM-enabled devices can be susceptible to malware and hackers. To mitigate risks, avoid clicking on suspicious links, downloading apps from untrusted sources, or using public WiFi without additional protection, such as a VPN. Still, eSIMs are generally more convenient than regular SIM cards.

Can I use more than one eSIM app on my phone?

Yes, it’s possible to use multiple eSIMs on phones and tablets, whether Android or iOS. You can have multiple providers for different needs (calls, internet access, etc.). Depending on the model, iPhones can store 5-10 eSIMs and Androids can store 5-7 eSIMs. However, you can actively use only 2 eSIMs at the same time.

Connect Anywhere With the Best eSIM for International Travel

Anyone who wants to reduce internet access costs abroad should get an eSIM. They’re more convenient, secure, and easier to set up than regular SIM cards. They also support remote activation and let you use multiple providers without the hassle of swapping physical SIM chips.

Not all providers offer great prices, voice minutes, or data sharing. That’s why you should compare the best eSIM services based on your needs, such as destination, travel time, and required functionality. With all the options I discussed, finding the best service for you shouldn’t be a problem.
