Changing an old number on to a new sim.

[Lucy123456789]

Hi there, I'm kind of new to all of this number changing over stuff and my old phone was stolen a month or so ago, how can I put my old number on to my new sim so that I can access my apps that use my old number?

@Lucy123456789You should report it Guide: Lost or Stolen O2 Device? - How to Report it 

O2 will then send you a new sim with your old number on.

If you have a replacement or when you get it, you will need to call O2 to lift the bars on your account and activate the replacement sim with your number on it.
