New network upgrade sim

[marconi]

O2 have sent me a new sim as my old one will cease to work on 1st April due to network changes. How do I swap my contact numbers to the new sim ?

You'll need to copy any contacts you have on your sim to your phone memory.

Once you have done that, you can do the sim swap Guide: Sim Swap: a mini guide 2017 update 

although your contacts will still remain on your old sim too.
