Your package will arrive
Along with your phone/sim, you’ll get a welcome pack showing you how to get started.
Activate your SIM
If you ordered a SIM only plan, you’ll need to activate it at www.bt.com/go. If you ordered a phone as well as a SIM, or you’re upgrading your existing plan, then your SIM is good to go.
Want to keep your old number?
Visit www.bt.com/keepyournumber and enter your PAC code (from your old provider). If you’re not using a BT mobile, make sure it’s unlocked first.
Your phone/SIM will arrive within 1-2 business days.
