I want to change my number at o2 via the app, but my Instagram and my laptop and a few other things run on this current number. So I wanted to ask if I change my number now whether I have to enter the new number on Instagram & co or whether it saves everything by itself.
So if you have your Instagram account or generally an account with your old number, you can no longer take over the account if you have not previously inserted the new number as far as I know.
Oh that's stupid, because I'll only get the number later.
Oh well, I know myself reasonably well, I also had the same problem and then I created an account with my main email, which is always the best.
Thank you.
