eSIM in United Kingdom: frequently asked questions
Will my phone work with an eSIM in United Kingdom?
If your device is eSIM-compatible and carrier-unlocked, yes. Check our compatible devices list before you buy to be sure.
How much does an eSIM for United Kingdom cost?
Plans for United Kingdom start at €1.70 (1 GB · 3 days). You pay once, with no contract or subscription, and use the data within the plan's validity. The price per GB starts at €0.23.
When should I activate my United Kingdom eSIM?
Each plan shows before you pay when it starts counting. Plans that start on connection start counting the first time they connect to a network in one of the countries they cover: install the eSIM before you leave, keep the line off until you arrive in United Kingdom, and you'll have data as soon as you land. Some also work in other countries (each plan lists which): if the line connects earlier, at home or on a layover, it starts counting there. Plans that start when you buy them are best bought on the day you'll start using them. Plans that start when you install them are best installed when you arrive.
Do I keep my own phone number?
Yes. The eSIM adds a data line for United Kingdom while your usual SIM and number stay active for calls and texts.
What happens when my data runs out in United Kingdom?
You can buy another plan at any time from your dashboard — no need to wait, reactivate or visit a shop.
Is United Kingdom included in EU roaming (roam like at home)?
No. United Kingdom is outside the EU's regulated roaming zone, so the data allowance of an EU plan does not apply there automatically; some operators add it through their own travel packages, so check with yours before you go. With a Telcomia eSIM you pay a fixed prepaid price for data in United Kingdom, with no roaming charges on your bill.
How much data do I need for United Kingdom?
As a guide: maps, messaging and email use about 1 GB a week; add social media and photos and you reach 2–3 GB; video calls and streaming can use 1 GB a day or more. If in doubt, choose the next size up — you can add another plan from your dashboard at any time.
Can I use the same eSIM in other countries besides United Kingdom?
Yes. Besides single-country plans, Telcomia offers regional and global plans that cover several countries with one eSIM. If United Kingdom is part of a longer trip, choose a regional or global plan on the pricing page.
