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.

You need to contact O2.

Thank you!

Are you saying that the Prepaid card Sim card cannot be switched to Postpaid? I need to buy a new Sim card?

Context: I am staying abroad for a couple of months until I go back to the UK. Meanwhile, I want my line to switch to postpaid and the bills delivered to my address in hard copy.

@SimonSef 

Yes, you need a different sim, but they are free.

I am currently out of the country - is there any way that I can switch from prepaid to postpaid without a new sim card? if no, is there a way to receive a hard copy bill to my address with prepaid sim card?

[MI5]

@SimonSef 

You can switch without using the correct sim but some features may not work, particularly texts and data.

You would have to manually configure the services each time you turned your phone on.

There are no bills for PAYG so nothing to send, but you can arrange the transfer by calling and request the bills be sent to your home address for the contract account.

Good to know!
I am trying to change the tariffs (@Choose Tariff) but I am only shown prepaid tariffs.
How do I change from prepaid (P2G) to postpaid (Pay monthly)?

[MI5]

@SimonSef 

You have to call O2 on the numbers I gave you above.

[SimonSef]

I want to do it online (either on Web or Mobile application)

The only way is to call, sorry.
