1. Buy a pay-as-you-go SIM when you arrive
When you first arrive, you may not pass credit checks or know which provider to choose. A pay as you go SIM gives you a quick UK number without a long contract.
What to do: Go to a mobile shop or supermarket and choose a pay as you go SIM from providers like EE, Three, Vodafone or O2. Ask staff to help activate the SIM and top up some credit for calls, texts and data.
What do you need: You need an unlocked phone, some cash or a payment card and, in some shops, your passport as ID.
Outcomes: You will have a working UK number within a short time so employers, schools and services can reach you.
Lifehack: Start with a small top up first so you can see the network quality in your area before adding more money.
2. Compare SIM-only monthly deals
3. Check contract length against your visa
