change of the phone no

[Anonymous]

I lost my old phone with a number and had got a new sim with a new pay and go number, how to change it in my account?

If you pop an O2 store they will transfer your original mobile number and tariff into a blank sim for you.

If you want to keep the new number then you can link it in to your account or ask cs in 4445.
