ALL mobile phones have a SIM CARD - It's what distinguishes the individual identity of the phone.
O2 SIMs are useful for purchasing a plan of payment from the O2 telecommunications provider for a mobile phone. SIMs are meant to refer to SIM cards that identify a subscriber and allow one to use a prepaid plan to communicate and operate a phone.
