How does eSIM work for international travel?
Alright, let’s break it down nice and simple. eSIM technology is a game-changer for people who love to explore the world. Why? Because instead of relying on removable SIM cards, travel eSIMs are built directly into your smartphone or device. This setup means you can connect to local networks anytime and anywhere, without ever having to handle a tangible SIM card. Just land, turn on your device, and voilà – you’re connected!
Intrigued? Don’t worry, we dive deeper into all the travel eSIM details in this article.
How to set up a travel eSIM
Okay, so you’re sold on the idea of travel eSIMs, but how do you actually get started? Well, Setting up a travel eSIM is a simple, easy and quick process:

1. First things first, do a quick check to make sure your smartphone supports eSIM technology. Most modern devices do, but it’s always better to be safe than sorry.

2. Next up, pick your travel eSIM provider. There are quite a few in the market, so do a little research to find one that fits your travel style. Our Buying Advice can help! Once you’ve made your choice, download their app.

3. From there, it’s just a matter of selecting a plan that covers your specific needs; whether that’s data, calls, SMS, or maybe a country-specific plan.

4. Finally, just follow the provider’s instructions to download and activate your travel eSIM profile. It’s usually as simple as following prompts from an app or scanning a QR code. And just like that, you’re ready to roam!
Side note: Some providers like Ubigi have a slightly different process, where you download a single eSIM profile after registration. But don’t sweat it – we’ve got a full review on Ubigi that’ll walk you through all the details.
The advantages of eSIM for travelers
Okay, so eSIMs sound pretty cool so far, but why should you really care? Well, they come with a bunch of advantages, especially for us travelers. We’ve covered all the pros (plus the cons) in this article.
Now, let’s talk about the main benefits, starting with the one thing that gets us all excited: Saving that money!
- Cost savings: One of the biggest perks of using a travel eSIM is avoiding those outrageous international roaming fees from your home carrier. With an eSIM, you can connect to local networks overseas at significantly lower prices. Plus, there’s a whole world of travel eSIM providers out there offering all sorts of data plans for data and sometimes calls and SMS. That means you get to pick and choose the perfect package to suit your needs, and keep more of your hard-earned money for the important stuff – like sampling all the local cuisine!
- Flexibility and convenience: eSIMs are all about it! In fact, this level of hassle-free remote management might just be one of the biggest game-changers when it comes to using eSIMs for travel. Since eSIMs are 100% digital, you basically have complete control over your mobile setup right from your device. With just a few taps you can download a new provider’s app, add or remove plans, change your data package and even switch between networks, all without ever having to physically touch a SIM card.As you can imagine, this comes in handy especially if you’re visiting multiple countries or need different services based on your travel activities.
- Ease of activation: Activating a travel eSIM is typically a straightforward process. Most of the time, it’s as simple as following steps from within an app, scanning a QR code or entering an activation code from your provider. That’s it! For us, this ease of activation has been huge in maximizing our travel experiences right from the get-go, as we haven’t had to visit a physical store or deal with paperwork ever since.
- Enhanced security: You know how easy it is to lose or misplace those tiny physical SIM cards, especially when you’re traveling? With an eSIM embedded right into your phone, you don’t have to worry about losing your SIM or dealing with potential data breaches if it falls into the wrong hands. Also, since the travel eSIM is essentially part of your phone’s core system, it gets to take advantage of all the heavy-duty security your smartphone packs, such as encryption and biometric authentication like fingerprint and facial recognition.
Challenges and considerations
Now, as awesome as eSIM technology is, there are a few potential roadblocks to keep in mind before you go all-in on travel eSIMs:
- Device compatibility: This is kind of a big one. Unfortunately, not all devices are eSIM compatible, so it’s important to verify if your specific device model supports this technology before relying on it for travel. If you’re unsure, you can check your device’s compatibility here.
- Internet dependency: To set up travel eSIMs effectively, you need a solid internet connection. Without it, activating or switching eSIM profiles can be problematic, especially if you land somewhere without internet access. Definitely something to plan around.
- Network locking: Sometimes carriers can be… controlling. If your device is locked to a specific carrier, it won’t accept an eSIM from another provider, limiting your international data plan options.
Travel eSIMs are very convenient when they work properly, but a little prep work is key to avoiding potential issues while traveling.
Tips to make the most of your eSIM when traveling internationally
Okay, so those potential eSIM roadblocks we mentioned earlier? Nothing to get too worked up about – where there’s a will, there’s a way! Here are some practical tips that have worked really well for us on every trip:
- Check device compatibility: First things first, confirm your device supports eSIM technology. It’s usually just a quick settings check away. But if you need the full rundown, we’ve got step-by-step guides and a full list of eSIM-ready phones right here.
- Ensure your phone is unlocked: Like we said previously, if your phone is network locked, it won’t work with an eSIM from another provider. Make sure your phone is SIM-unlocked before installing a travel eSIM. If not, sometimes a call to your carrier to request an unlock can do the trick pre-trip.
- Pre-purchase your travel eSIM: Buy your eSIM plan ahead of time so that you can get connected as soon as you arrive at your destination. This will spare you the hassle of searching for wifi to activate your travel eSIM.
- Pre-plan your travel eSIM consumption: We recommend doing a quick self-assessment of how you’ll really be using data/calls/texts during your trip. This will help you choose the right travel eSIM package to match your needs and travel style without overpaying.If you expect to use data-heavy services like streaming, online gaming or GPS navigation, then you’ll likely need a plan with more data. On the other hand, if your activities are mainly offline or you think you’ll be able to use wifi often, then you might be able to opt for a lighter plan. Here are some benchmarks to guide you:

General data usage guidelines
- Google Maps for navigation can consume about 0.6MB per minute.
- General web browsing varies but can expect to use 1-3MB per minute.
- Social media is also around 1.5-2 MB per minute, depending on what you’re looking at. If it’s video content, expect that number to be a lot more.
- Streaming video can consume around 1GB per hour, HD video can be more like 3GB per hour.
(1 GB = 1,000 MB )

- Choose the right plan: When shopping for travel eSIM data plans, think through whether you need broad regional coverage across multiple countries which can be more costly, or if a cheaper, single country-specific plan makes more sense if you’re visiting just one place. The right fit can save you money and hassle.


- Manage data usage: Many apps continue to use data in the background for updates and notifications, which can quickly use all of your data. Before activating your travel eSIM, make sure to check your phone’s settings first to disable all non-essential apps from using cellular data. That should help stretch your data much further. Here’s how you can disable background data usage for non-essential apps on iOS:

1. Tap on the “Settings” icon on your home screen.
2. Scroll down and tap on “Cellular”, “Mobile Data” or “Mobile Service” depending on your region.
3. Manage cellular data for each app:
- Under “Cellular Data” or “Mobile Data”, you’ll see a list of all apps installed on your iPhone.
- Next to each app, there’s a toggle switch. By default, these may be turned on, allowing the apps to use cellular data.
- Go through the list and toggle off the switch for each app that you want to prevent from using cellular data. This will stop them from using data.

4. Consider turning off “Background App Refresh”:
- Go back to the “Settings” and tap on “General”.
- Tap on “Background App Refresh”.
- You can choose to disable “Background App Refresh” entirely or selectively for apps that you don’t need updating in the background. This setting controls whether apps can refresh content in the background when they’re not actively in use, which can significantly impact data usage.

5. Use “Wi-Fi Assist” carefully:
- “Wi-Fi Assist” automatically uses cellular data when Wi-Fi connectivity is poor. This feature can use more data than expected.
- To find this setting, stay in the “Cellular” or “Mobile Data” menu and scroll all the way to the bottom.
- You can turn off Wi-Fi Assist to prevent your iPhone from automatically switching to cellular data when the Wi-Fi signal is weak.
- Use wifi for heavy data tasks: Whenever possible, connect to wifi for high data usage activities like streaming videos or downloading large files. We always preload our devices with our favorite shows at home over wifi before trips to avoid exceeding our data limits or any unwelcome data costs.
- Calling? Texting? Understand travel eSIM limitations: We usually go for data-only eSIM plans as they are much more common, but if you need actual voice/SMS too, double check if those features are included in your chosen plan. If not, internet calling VOIP apps like WhatsApp, Facetime, Skype etc can cover you.
- Hotspot sharing is caring: It’s always a good idea to check whether your travel eSIM allows using your phone as a portable hotspot to share your data connection, especially if you’re carrying multiple gadgets or traveling with other people. Unsure if your eSIM supports hotspot? We test every eSIM provider for hotspot availability in our country guides.
