What is the right SIM for me?

[Anonymous]

I know someone like me who knows so little  and understands even less about mobile phones and tariffs and SIMs etc really ought not to be allowed loose and unaccompanied in this Community.  But here is my question.  I have a Galaxy S3 that I want to keep as a backup for when my own phone is out of action, being charged or whatever.  All I need (i think) is a P&G SIM card that will allow me to send/receive a few texts and make/receive a few voice calls a month.  We are talking fewer than 150 texts and fewer than 20 calls per month so I don't want to have a monthly financial commitment.  In other words I want a SIM that will allow me to top up as and when I need it with any unused balance moving forward to the ensuing month.  Is such a thing available from O2?  If not how do I get my S3 "unlocked" from O2 so that I can try other Networks.   Sorry if this is something I should know already.

At we've said it could be location based.

Although my O2 signal and 4g are very stable.

Very weird.

Enough said.
