Things to consider before choosing an eSIM for traveling in the United Kingdom
Here are a few things to consider when choosing an eSIM for traveling in the United Kingdom:
- Destination coverage. Check if the eSIM service has coverage across the UK or only parts of the country. If you’re traveling across the region, confirm that the eSIM has coverage in neighboring European countries.
- Communication needs. Decide if you require only data or want to make calls and send messages with your eSIM. Some eSIM providers offer phone numbers for calls and SMS, while others may only allow you to receive calls and texts.
- Data plans. Consider the amount of data you'll need during your trip and decide if you’d like a fixed plan or a pay-as-you-go package. If you’re getting a fixed plan, ensure you can top up your data if necessary.
- Price. Compare pricing between providers to find a plan that fits your budget. Remember that the cheapest option isn’t always the best – look for a balance between cost, coverage, and reliability. Some eSIMs offer regional bundles that include the UK and nearby countries, which can be more cost-effective if you travel beyond the UK.
- Validity period. Check the eSIM’s validity period. This indicates how many days it remains active once it is activated. Ensure the validity period aligns with the duration of your trip.
- Tethering support. Check if the eSIM provider allows tethering. This feature allows you to share your device's data connection as a mobile hotspot, which can be beneficial for connecting multiple devices during your travels.

How we tested and ranked these eSIMs for the UK
Together with the Cybernews team, I dived deep into research and hands-on eSIM testing to find the best options for the UK. Here’s a quick look at the criteria we used to rank them:
- Coverage in the UK (20%). I reviewed how well each eSIM provider covers the UK and chose the ones with the strongest and widest coverage. The eSIMs on this list work reliably across the UK and even in nearby countries like Ireland and France.
- Network connection (20%). eSIM providers offer different types of connections like 3G, 4G, LTE, and 5G. I focused on eSIMs that deliver fast and stable speeds across the UK.
- Data plans (20%). I looked at the types of data plans each provider offers and chose those with flexible options for both short trips and longer stays. I also checked which eSIMs include support for calls and texts.
- Price (20%). eSIM prices can vary quite a bit. I compared the costs across different providers and included the ones that offer the best value for money.
- Compatibility (10%). I reviewed each provider’s list of supported devices and picked eSIMs that work with a wide range of iPhones and Android phones, ensuring they would be easy to set up and use.
- Customer service (10%). I tested how easy it is to reach customer support and how quickly they respond. The eSIMs on this list all have helpful support teams and multiple ways to get in touch.
Does my phone support eSIM?
Before getting an eSIM, you need to check your phone’s compatibility. Your phone's eSIM compatibility largely depends on the brand and model. Fortunately, most new smartphones support eSIMs. Some don’t even have physical SIM card holders anymore. Here’s how to check if your phone supports eSIM.
Many modern Android phones support eSIM. To verify your phone’s compatibility, go to Settings > Connection > SIM card manager. If there’s an Add eSIM option, it means your device supports this technology.
iPhone XR and later models support the eSIM feature. To check compatibility, you can refer to Apple’s official list of supported devices or go to Settings > General > About on your iPhone. If you see the Available SIM option and a 15-digit IMEI number, your phone supports eSIMs.
If your phone is carrier-locked, you may be unable to use an eSIM. You need to contact your operator and confirm if your phone is locked and if it’s possible to unlock it.
How to activate the eSIM data plan for the UK on your phone
Activation process for an eSIM data plan may vary slightly, depending on the provider and the model of your phone. However, there are three main ways to activate an eSIM.
This is one of the simplest ways to activate an eSIM. Here’s how to do it:
- Sign up and choose a data plan from your eSIM provider
- Download and install the provider’s app on your device
- Open the app and tap the Activate button
The eSIM will begin installing automatically. If necessary, follow any prompts to adjust your device settings to finish activation.
QR-based installation is another easy way to activate your eSIM. Here’s how it works:
- Choose and purchase a data plan from your eSIM provider – you’ll receive a QR code via email after checkout
- Open your phone’s settings and select Add eSIM or Use QR code
- Scan the QR code to start the installation
- Follow the on-screen instructions – set the eSIM as your primary data SIM and turn on roaming if needed
Manual eSIM installation is a bit more technical but still doable. Here’s how to set it up:
- Buy a data plan directly from your eSIM provider – you'll receive an activation code, SM-DP+ address, and other setup details
- On iOS, go to Settings > Mobile Data > Add eSIM and choose Enter Details Manually. On Android, go to Settings > Network & Internet > SIMs and select Add eSIM manually
- Enter the provided eSIM information to complete the setup
I recommend closely following your chosen provider’s instructions. They often include screenshots or device-specific steps.
You can start activating an eSIM before your trip, but in some cases, the activation may only be completed once you arrive at your destination – only then will you be able to access the internet, make calls, and send texts.
Where to buy a prepaid eSIM card for the UK?
Most eSIM providers don’t have physical stores, so the best place to purchase an eSIM is directly from their website. You can browse through eSIM plans for different locations on the website of your preferred eSIM provider.
While most eSIM providers allow you to buy your preferred plan from their site, some may direct you to download their app to complete the purchase. Regardless, the process is generally straightforward.
All the eSIM providers I’ve reviewed accept various payment methods, including debit/credit card, PayPal, Apple Pay, and Google Pay.
When to order/activate an eSIM card for the UK?
You’ll need internet access to buy and set up your eSIM, so it’s best to purchase a data plan while booking your ticket and creating an itinerary for your trip. However, I recommend waiting until a day before you set off to activate the eSIM.
Some eSIMs are activated the moment you install the eSIM app. However, others must be connected to a local network before activating. To prevent your eSIM from expiring before the end of your trip, wait until just before you travel to activate it.
Benefits of using an eSIM in the United Kingdom
There are several reasons you should consider using an eSIM in the United Kingdom, including:
- Instant data access. You can activate your eSIM upon arrival and get instant access to data services without having to wait until you get a physical SIM card.
- Convenience. You don’t have to deal with the hassle of visiting a store to get a SIM card, saving you valuable time.
- Retaining your number. You can keep using your domestic phone number while reserving the eSIM for internet access.
- No physical SIM is required. You don’t have to remove your physical SIM card to use an eSIM, streamlining the process of getting connected.
- Cheaper costs and faster speeds. Say goodbye to expensive and slow roaming speeds. eSIMs offer competitive rates and faster connectivity options.
- Easy data top-up. You can easily top up your eSIM data as needed, ensuring you stay connected without interruptions.
Things to know about using an eSIM in the UK
Here are a few things to keep in mind about using an eSIM in the UK:
- Ensure your phone is unlocked. Locked phones are tied to a specific mobile service provider, restricting your ability to connect them to eSIM cards.
- Check phone compatibility. Not all mobile phones support eSIM cards, so verify that your device is compatible with them before purchasing a data plan.
- Calling and phone number. Not all eSIMs come with a phone number or calling support. Some eSIMs may only allow you to receive calls and SMS.
- Activation timing. Note that the validity period of some eSIM cards starts counting after installation, while others begin upon connecting to a supported network for the first time. Also, some eSIM cards must be activated before the trip commences. Avoid activating the eSIM card too early to maximize its validity period.
- Activation process. eSIMs have different activation methods, such as app-based, QR-based, or manual activation. Choose the method that suits your preferences and follow the instructions provided by your eSIM provider.
- Expiration period. There may be a time limit for activating the eSIM card, typically within 1-3 months of purchase. After this period, the eSIM may expire. It's essential to activate it within the specified timeframe to avoid any issues.
How to make calls with eSIM
If you are planning to make calls with your eSIM, here are the options available to you:
- Choose an eSIM provider that supports calling. Some eSIM providers offer phone numbers for making calls.
- Use your domestic SIM card. While eSIMs primarily offer data plans, you can use a physical SIM card from your home country to make international calls. This way, you reserve your existing phone number for calls while using your eSIM for data services.
- Use VoIP apps. Voice over Internet Protocol (VoIP) apps such as WhatsApp, FaceTime, or Google Voice are an alternative option for making online calls. These apps use your data connection to make calls, bypassing traditional cellular voice networks and offering cost-effective communication solutions.
