Want to know something.

If I call o2 tomorrow and ask about moving from pay and go to contact will I be able to use the same number and sim card that I am already using?

@Luke30 

You keep the same number but they will send a new sim as payg and contract sims are different.

Switching your number from Pay As You Go to Pay Monthly

Fill in the keep my number form. You'll need your temporary Pay Monthly number from your O2 confirmation email or sim pack. We’ll transfer your number within one working day (Monday-Friday, 9am-5pm, excluding bank holidays). If we receive your code after 5pm, you’ll switch within two working days.

On the day of the switch, your Pay As You Go sim will lose signal. When this happens, put your Pay Monthly sim in your phone. If you don't have signal, switch your phone off and on every couple of hours until you get a signal. If you still don't have signal by 6pm, contact us.

Texts and picture messaging can take up to 24 hours to work after the switch.

If your Pay As You Go balance is under £350, it will be transferred to your Pay Monthly account when you receive your second bill. If you're entitled to a loyalty bonus, up to £550, we'll add credit to your fourth bill.

Hi @Luke30 hope you're doing well this week. Did you end up switching from PAYG to Pay Monthly after you posted your query here? Did everything go ok?
