The eSIM for the UK
There are two very different reasons to want a UK eSIM, and most sites blur them together. BuyUKeSIM keeps them clear: a real UK +44 number for receiving verification SMS and calls, or a travel data eSIM for internet while you visit Britain. Pick the one you actually need below - both are paid in crypto, with no KYC and an instant QR.

Which UK eSIM do you need?
Ask one question: do you need a British phone number, or do you need internet in Britain? They are two separate products. A travel data eSIM will not give you a +44 number, and a UK number is not a data-roaming plan.
UK Number (+44) eSIM
A real UK mobile line delivered as an eSIM. It receives unlimited incoming SMS and incoming calls from anywhere in the world, so you can pass phone verification on WhatsApp, Telegram, PayPal, Wise and other apps that require a UK number.
- Real +44 mobile number, not VoIP
- Unlimited incoming SMS and calls
- Works worldwide via UK carrier roaming
- No KYC, no account, instant QR
- Keep it active with a $15 top-up every 6 months
Choose this if you need to receive UK codes and calls.
Travel eSIM for UK Data
Prepaid mobile data for using the internet while you are physically in the UK - maps, messaging, calls over the internet, streaming. It is not a phone number; it is a data plan for a trip. Choose the size that fits your stay.
- Prepaid data for your UK trip
- Plans from $6.99, pick your data size
- Instant QR, activate on arrival
- No KYC, crypto checkout
- No UK phone number included
Choose this if you are visiting the UK and just need internet.

Travel data
Using data while you are in the UK
If you are travelling to London, Manchester, Edinburgh or anywhere in Britain and simply need internet, the travel eSIM is the right choice. It runs on a real UK carrier network, so you get proper 4G and 5G coverage across cities and most of the country, without swapping your physical SIM or paying home-network roaming fees.
- Real UK carrier coverage across England, Scotland, Wales and Northern Ireland
- Choose a data size to match how long you stay
- Delivered as a QR - install before you fly, switch on when you land
- Keep your home SIM in the phone for your own number, data on the eSIM
- Plans start from $6.99, priced by data amount rather than a fixed monthly bill
We publish the starting price here and keep exact per-plan pricing on the live catalog, since data sizes and coverage packs change. See the travel eSIM page for the current options.
What you can do
What a UK eSIM lets you do
The two products cover two different jobs. Here is what each one actually unlocks.
Verify apps with a UK number
Receive the SMS or call code to activate WhatsApp, Telegram, PayPal, Wise and other apps that ask for a British number - from any country.
Receive UK SMS and calls
Your +44 line accepts unlimited incoming texts and voice calls worldwide, so codes and callbacks reach you wherever you are.
Run a second WhatsApp
Register WhatsApp Business or a second WhatsApp on the UK number while your personal account stays on your local SIM, in dual-SIM mode.
Get online across Britain
With the travel eSIM, use data in London, Manchester, Birmingham, Glasgow and beyond for maps, rides, bookings and messaging.
