About mobile data in the UK
Coverage in the UK is strong in towns and cities, and can be weaker in remote countryside and parts of Scotland and Wales.
How to choose
- Validity: pick a plan that lasts at least as many days as your trip.
- Data: maps and messaging need little; video calls, hotspot and streaming need much more.
- Phone: it must be eSIM-capable and unlocked.

Questions
How much does an eSIM for the UK cost?
Our UK trip plans range from $4.99 to $70.99 USD depending on data and validity.
Can I install the eSIM before I arrive in the UK?
Yes. Install it at home over Wi-Fi, keep it switched off, then turn it on with data roaming enabled for the eSIM when you land.
Does a travel eSIM include a phone number?
No. These plans are data-only. Your main SIM stays in the phone, so your usual number keeps working for calls and texts where your home carrier allows it, and messaging apps work over the eSIM data.
Is my phone compatible?
You need an eSIM-capable, carrier-unlocked phone. Check the compatible devices list, or dial *#06# and look for an EID number.
When does the plan start?
Validity normally starts when the eSIM first connects to a network at your destination, so you can install it at home before you fly.
