Keeping phone number

[jacob74]

I used the online O2 form for keeping an old phone number after switching sims, but it keeps saying “oops! Something went wrong.” Even though I’m entering the correct details. Idk why it’s not working.

My old number was on a pay as you go sim, and on a different account.

This looks like something you’d need to call O2’s customer service team about – give them a call on 202 or 0344 809 0202
