Re: Upgrading my phone

As you say you are keeping your existing handset and the upgrade is for your daughter then unless your sim is broken keep using that.

Re: Upgrading my phone

Your contract stays with the SIM so you must keep using your original SIM in your original phone..
Your daughter must use her original SIM in the new phone unless she is changing her contract.
I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion. This is not Customer Service so we are unable to help with account specific issues.

Re: Upgrading my phone

Hi @Joanna1, did the replies above help you understand better how to proceed or do you have any more questions? 


You daughter will surely be delighted, which device are you giving her? smiling
