United Kingdom travel data eSIM
What is a United Kingdom eSIM?
A United Kingdom eSIM gives you mobile data for navigating England, Scotland, Wales, and Northern Ireland. It suits travellers moving between London, Edinburgh, and Manchester who need constant connectivity. Whether you are checking train times in Cardiff or booking tickets in Belfast, this data-only plan keeps you online without swapping physical SIM cards. It is a practical tool for staying connected during your visit to the British Isles.
Your eSIM connects to EE 5G or 3 4G networks. The specific network you use depends on your location within the UK. This setup allows you to access mobile data for maps, messaging, and browsing. The connection activates upon your first use at the destination. You retain your existing phone number for calls and texts via Wi-Fi or roaming, while the eSIM handles your data needs.

Questions people actually ask
If yours is not here, write to us — we answer within 24 hours.
Which operator networks does the UK eSIM use?
It connects to EE 5G or 3 4G. Your device links to the available network based on your location. This means you access mobile data through these major carriers, with the specific connection depending on where you are within the United Kingdom.
Does this plan work in the Republic of Ireland?
No, this is a single-country plan valid only in the United Kingdom. The Republic of Ireland is a neighbouring country but is not included. If you are travelling to both, you need a regional plan that covers multiple countries for your entire trip.
Which plan size suits a trip to London and Edinburgh?
For a two-city trip, the 3GB / 30 days plan is a rough guide for moderate usage. If you stream video or use maps heavily, the 5GB / 30 days option provides more buffer. Choose based on your expected daily data consumption habits.
Will I lose my own phone number?
No. Your physical SIM stays in the phone and keeps your number for calls and WhatsApp. The eSIM only carries data, so both work side by side.
When does my plan start counting down?
When the eSIM first connects to a network at your destination — not when you buy it. So you can install it days before you fly without losing any time.
Is my phone compatible?
Most phones from 2018 onwards are: iPhone XS and later, Google Pixel 3 and later, Samsung Galaxy S20 and later. Your phone also has to be carrier-unlocked. Dial *#06# — if an EID appears, you have eSIM. Full list on our Device Compatibility page.
How fast will I get my QR code?
Usually within a couple of minutes of payment, by email. If it has not arrived, check spam first, then write to us and we will resend it immediately.
Can I use hotspot or tethering?
Yes, on every plan we sell. Share the connection with a laptop, a tablet or the rest of your group.
What if I change my mind?
If you have not installed the eSIM, you get a full refund within 180 days. Once a profile is activated and data has been used it cannot be refunded — the allowance is consumed from the network. Full detail in our Refund Policy.
Do you sell plans for groups?
Yes. For Umrah and Hajj groups, student trips and tour operators we deliver the QR codes as a single batch before departure, at group rates. Email us with your group size and destination.
