UK eSIM: Frequently Asked Questions
Single-country or the Europe regional plan?
If the United Kingdom is your only destination, this plan does the same job as the regional one. As soon as a second European country is on the route, the Europe 42-country plan is simpler and saves a mid-trip purchase.
Will the connection drop when I cross a border?
You may see a brief re-registration as the profile picks up the next network, the same way roaming behaves, but you do not need to do anything — no swapping, re-scanning or reconfiguration.
How much data do I need for a week in the United Kingdom?
We would not recommend the smallest plan — leaving headroom is the safer choice. Maps, navigation, translation, social media and messaging add up to more than most people expect, and running out of data abroad is the worst moment to find that out. For most travellers around 3GB a day is a more comfortable starting point. Where this destination offers a total-data plan (10GB or 20GB, for example), that is usually our first recommendation: a heavy day will not leave you stuck, and the allowance spreads across the whole trip. If you stream video, upload a lot of photos, or need to share the connection with another device, an unlimited plan is the simplest answer.
How are the days counted on this UK eSIM?
Counting starts when you scan the QR code and activate. The first day runs until 23:59 (UTC+8 Time Zone) that same day, and the second day begins after 00:00. Activate after you arrive in the United Kingdom rather than before you leave, so you do not waste a day.
When should I install the eSIM?
Install on your departure day while your phone still has internet — airport Wi-Fi works, or your home network before you fly. An eSIM cannot be activated without a connection.
How long is the QR code valid?
The eSIM must be activated within 30 days of delivery or it expires, and that is the buyer’s responsibility. Ordering about a week before departure is ideal rather than months ahead.
Which devices are not supported?
iPads, tablets, customised devices, contract phones, carrier-locked phones, and jailbroken or rooted devices are not supported. Before ordering, dial *#06# — if an EID appears your handset supports eSIM. Also confirm the phone is not locked to a carrier.
How soon will I receive it after paying?
The QR code is sent automatically to your contact email within about 10 minutes of payment. If it does not arrive, check your spam folder or contact our LINE official account @peanutmo / WhatsApp +886-921-963-203 (10:00-17:00, UTC+8 Time Zone).
