Upgrading and confused!

[Anonymous]

Decided recently to upgrade from Pay and Go (SIM only) to Pay Monthly (SIM only). Got the new SIM in today and have put it in my phone but the phone seems to think it's still on the old set-up ie my old number and Pay and Go. Tried to make a call out but it's telling me to top up my Pay and Go balance. Tried ringing the new SIM's number but it just goes to answering service. I do want to keep the same number and have just filled in the online form to that effect tonight but, what am I doing wrong?

The new sim will need activating but you will have to call customer service.

It will have to switch over.
If you've just done the form it may take upto 24 hours.
Just checking you used this form?

Most changes like these happen at midnight.

If it's not happened by tomorrow then please call customer services.

Hi no but trying to fill it in now and can't because I don't know my existing Pay and Go SIM card's serial number. It's just a wee black chip and there's no numbers on it.

Well I'm having some issues with my saved links. I'll check them out. 😞

Thank you for inserting the specific link required.

Are they not on the sim carrier it came in?

Possibly ringing o2 on 202 will be of help or pop inot your local o2 high street store with everything.
