Re: samsung phone

Chances are that virgin have locked your phone so that no other sim cards from other mobile networks can be used in it. You need to get your phone unlocked, which can be done either by virgin (which will be expensive, around £40) or you will probably find some store on your local high-street that will do it at a cheaper rate (normally around £10). When your phone is unlocked, you will be able to put any sim card in it, no matter what network it is. Hope this was useful!
