Activated iPhone Uk, with other O2 card

[jainaman86]

Hi
if we have an already activated o2 card, can we use it with some other o2 card, as in one on PAYG or simplicity tariff?

If it's activated via iTunes, you'll need to jailbreak with a different SIM card inserted, then you can use any o2 SIM.

if you do it right,you can use an existing o2 sim card with the iPhone and everything works just fine.
