FAQs about the London eSIM
Will my eSIM work the moment I land in London?
Install your Teraroma United Kingdom eSIM at home before you fly. The plan starts when your phone first connects to a local network in United Kingdom, as long as the eSIM line and data roaming are switched on.
Which networks does the London eSIM use?
Our current United Kingdom plans connect to EE, 3. The network your phone picks depends on the plan and local signal.
Do I need a separate eSIM for other cities in United Kingdom?
No. United Kingdom plans are country-wide, so the same eSIM works in London and anywhere else the local networks cover.
Can I keep my home number while using a London eSIM?
Yes. Teraroma eSIMs are data-only and run alongside your home SIM, so calls and SMS to your usual number keep arriving.
What if I need more data while I'm in London?
Top up your existing eSIM from the Teraroma top-up page. You don't need to install a new eSIM mid-trip.
