Keep my number

[Anonymous]

How long should it take to change my new sim to my existing number after the keepmynumber form has been submitted?

Usually the next day if all goes well.

I did this 2 days ago and nothing happened. Then I read...you should receive a text if it was successful.

I reentered the details again yesterday, I had a text saying it would be completed.

The only change in details I made was my current number, it wants the number of your new o2 sim, not the number you’re bringing over...

not very clear!

Actually I've just realised that the keep my number form is wrong for your purpose, hence nothing has happened.
You need a sim swap http://swapmysim.o2.co.uk/

Hey @Anonymous please do let us know how you get on with the sim swap?

Cheers @MI5 and @Anonymous

After three days of no response I rang 02 today and found that they had no record of my request. They have now done it over the telephone and it being Friday today it will now happen on Monday.

Hi @Anonymous thanks for coming back to update about the situation. Glad to hear it finally got sorted in the end. Hopefully it all goes well today!

It would have fallen over due to using the wrong form I guess.

Looks like it, thanks for recommending the sim swap one above. Hopefully everything's fine now but @Anonymous please do give us an update if you do get stuck again.
