Top 5 eSIM providers for United Kingdom

What to consider when choosing eSIM for traveling in United Kingdom

When choosing an eSIM for traveling in the United Kingdom, there are a few key factors to consider if you prioritize smooth communication:

  • Destination coverage. A key factor to consider is whether or not the provider’s eSIM covers the country you’re traveling to or a broader region, including Europe or neighbouring counties.
  • Communication needs. Decide if you require only data or if you also need to make calls and send messages. Some eSIM providers offer phone numbers for calls and SMS communication, while others may only allow you to receive calls and SMS.
  • Data options. Consider the amount of data you'll need during your trip. Choose from fixed plans, pay-as-you-go options, or top-up availability to add more data if necessary.
  • Validity period. Check the validity period of the eSIM, which indicates how many days it remains active from activation. Ensure it aligns with the duration of your travel.
  • Tethering support. Determine if the eSIM provider allows tethering, which enables you to share your device's data connection as a mobile hotspot. This feature can be beneficial for connecting multiple devices during your travels.

Does my phone support eSIM?

Before getting an eSIM, you need to check your phone’s compatibility. This will largely depend on the make and model. Fortunately, most new smartphones support eSIMs. In fact, 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 the Add eSIM option exists, the technology is supported by your device.
  • iPhone. Go to Settings > General > About. If you see the Available SIM option and a 15-digit IMEI number, eSIM is supported.

Another issue to consider is locked phones. If your phone is locked, you might not be able to use an eSIM. This shouldn’t be a problem for European travelers, but if you live in the US, for example, you will want to contact your operator and ask them if your phone is locked and if it’s possible to unlock it.

Benefits of using an eSIM in the United Kingdom

Using an eSIM in the United Kingdom offers several benefits, including:

  • Instant data access. Activate your eSIM immediately upon arrival and gain instant access to data services without the need to wait for a physical SIM card.
  • Effortless activation. Skip the hassle of visiting a store – activate your eSIM instantly for quick and efficient connectivity, saving time and effort.
  • Retain your number. Keep your usual phone number while utilizing the eSIM for seamless access to data services, ensuring continuity and convenience.
  • No physical SIM is required. Avoid the inconvenience of removing your physical SIM card or searching for a store to purchase a new one while traveling, streamlining the process of getting connected.
  • Cost and speed benefits. Say goodbye to expensive and slow roaming data offered by your home country's mobile SIM card providers – eSIMs offer competitive rates and faster connectivity options.
  • Easy data top-ups. With some eSIM providers, you can easily replenish your data allowance, allowing for quick top-ups when needed, ensuring you stay connected without interruptions.

Things to know about using an eSIM in UK

When using eSIM in the United Kingdom, keep these crucial factors in mind:

  • Ensure your phone is unlocked. Locked phones are tied to a specific local mobile service provider, restricting the use of 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 features. Understand that not all eSIM plans support calling and provide a phone number. Some eSIMs may only allow receiving calls and SMS, not outgoing calls or SMS.
  • Timing of activation. Be aware that the validity of some eSIM cards begins after installation, while others start upon connecting to a supported network for the first time. Some eSIM cards also must be activated before the trip commences. Avoid activating the eSIM card too early or too late to maximize its validity period.
  • Activation process. It’s important to understand common activation methods such as QR code activation, app-based activation, or SMS activation. Choose the method that suits your preferences and follow the instructions provided by your eSIM provider.
  • Expiration period. Note that 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, so it's essential to activate it within the specified timeframe to avoid any issues.

How to make calls with eSIM

Ready to make calls with your eSIM? Here are the options available to you:

  • Choose an eSIM provider with a calling option. Seek out eSIM providers that offer plans with phone numbers for making calls, ensuring you have the necessary features for voice communication.
  • Utilize a domestic SIM card. While eSIMs primarily offer data plans, you can use a physical SIM card from your home country for calling purposes. This allows you to use your existing phone number and plan for calls while using the eSIM for data services.
  • Employ VoIP apps. Voice over Internet Protocol (VoIP) apps such as Skype, WhatsApp, FaceTime, or Google Voice provide 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.
