London Setup
A working phone is the setup task that makes every other task less painful
A practical guide to SIMs, eSIMs, UK numbers, arrival data and phone setup for your first days in London.
Quick answer
Get connected

- Have data before leaving the airport if possible.
- A UK number can help banking, jobs and housing.
- Do not lock into a long contract too early.
Data for arrival day
The first goal is maps, messages and payment verification, not the perfect phone contract.
- Download offline details.
- Have roaming or eSIM backup.
- Know how to reach your accommodation.
