Before You Begin: How to Choose the Best UK eSIM for You

Before you travel to the UK and decide to use an eSIM, there are a few key questions you should answer.

1. What is an eSIM?
   It's essentially a virtual SIM card. Most modern smartphones support the installation and activation of an eSIM.
2. Is Your Phone eSIM-Compatible?
   You can check your phone's compatibility list. Alternatively, you can dial *#06# and press call. If an EID number is displayed, your device is eSIM-compatible.
3. Do You Need Texting or Calling Features?
   Most eSIMs are data-only. Some plans may include calling and texting, but if your eSIM plan only has data, you can still make calls using data-based services like WhatsApp or FaceTime.
4. Are You Visiting Cities or Remote Areas?
   eSIMs will specify which network provider they use. If you need broader coverage, we recommend choosing a dual-operator eSIM, as these offer a wider network footprint. The strength of your signal depends on the carrier's network tower locations.
5. How Do You Choose the Right eSIM Plan?
   Different travelers have different needs. We recommend finding a plan that fits your specific requirements. You can also read our guide, "How much data do I need for international travel?" to learn more about how to select the right data plan.

Answering these questions will help you quickly understand what kind of eSIM you need.
