What to consider when choosing 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 countries in Europe.
• Communication needs: Decide if you require only data or if you’d like 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 options: 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.
• Validity period: Check the eSIM’s validity period. This indicates how many days it will remain active once it is activated. Ensure the validity period of the eSIM 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.

Comparison of the best eSIM providers for the UK

Here’s a side-by-side comparison of the best eSIMs for the UK:

While I recommend all these eSIMs for use in the UK, it’s best to assess your specific needs and choose an eSIM that’s best suited to you. For example, if you’re on a budget, opt for Saily, Instabridge, or Jetpac, as they’re the most affordable eSIMs for the UK. If you prioritize being able to make calls and send SMS, choose either aloSIM or Airalo (Discover+ global plan), as both eSIMs support calling and texting in the UK.

How we tested and ranked these eSIMs for the UK

I worked with the Cybernews team to conduct extensive research and methodical tests to find the best eSIMs for the UK. Here’s a brief overview of the criteria for our ranking:

• Coverage in the UK: I looked at each eSIM provider’s coverage in the UK and selected those with the broadest coverage. The eSIMs on this list have excellent coverage throughout the UK and also in neighboring countries like Ireland and France.
• Network connection: eSIM providers support different network connection types, including LTE, 3G, 4G, and 5G. I picked eSIMs that offer the fastest connection speeds across the UK.
• Compatibility: I checked the complete list of devices each eSIM is compatible with and selected eSIMs that work with a wide range of iPhones and Android devices to ensure easy installation.
• Data plans: I looked at the type of data plans each eSIM offers and picked those with an array of plans for both short-term and long-term travel. I also included some eSIMs that support calling and texting.
• Price: The price of UK eSIM plans varies from one provider to provider. I assessed the prices of plans from different eSIM providers and selected those with the most budget-friendly plans.
• Customer service: I checked the customer service channels of different eSIMs and selected those with multiple customer service channels and the fastest response times.

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:

• Android: Go to Settings > Connection > SIM card manager. If there’s an option to Add eSIM, your device supports this technology.
• iPhone: Go to Settings > General > About. If you see the Available SIM option and a 15-digit IMEI number, your phone supports eSIMs.

Note: 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 on your phone

The process of activating an eSIM data plan may vary slightly, depending on the provider. However, there are three main ways to activate an eSIM:

• Activating via the eSIM app: This is a straightforward activation method. It involves installing the eSIM provider’s app and clicking a button to activate the eSIM. You may be directed to make some changes to your device’s settings to complete the activation.
• Activating via a QR code: This is a popular eSIM activation method. Your eSIM provider will share a QR code (usually via email). Scanning the QR code will kick-start the eSIM installation process. Like app-based installation, you need to follow the on-screen prompts and you may have to change a few settings on your device to complete the process.
• Manual eSIM installation: This activation method is more technical than the others above. With manual installation, you need to go into your device’s settings and enter your eSIM details, like your eSIM activation code and SM-DP+address. We only recommend this option for tech-savvy users.

Note: While you can start the eSIM activation process before heading off on your trip, you may need to arrive at your destination before the activation process is completed, and you can start accessing the web, making calls, and sending texts with your eSIM.

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 your 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 an eSIM 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 need to be connected to a local network before they’re activated. 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.
• Convenient: You don’t have to deal with the hassle of visiting a store to get a SIM card, saving you valuable time.
• Retain 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 before purchasing an eSIM plan.
• Calling and phone number: Not all eSIMs come with a phone number or support calling. Some eSIMs may only allow you to receive calls and SMS.
• Timing of activation: 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 QR code activation, app-based activation, 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

Are you 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 allows you to 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 Skype, WhatsApp, FaceTime, or Google Voice are an alternative option for making calls over the Internet. These apps use your data connection to make calls, bypassing traditional cellular voice networks and offering cost-effective communication solutions.

Final thoughts on eSIMs for the UK

My team conducted thorough tests to select the best eSIMs for traveling in the United Kingdom and neighboring countries. Whether you're looking for budget-friendly data plans, effortless connectivity, or dependable customer support, there’s an eSIM on this list for you.

In my opinion, Saily is the overall best eSIM for the UK. It’s easy to set up, has excellent coverage in the UK, offers 24/7 customer support, and is known for its bargain prices.
