Hi Guys,

I'm a bit of a dimwit where these mobile phones are concerned. I mean, I've only just got out of keeping one in the car with the idea of keeping it in the car in case we are iinvolved in an accident and need some kind of physical help in getting out of there. OK, so I lust bought a phone for general (having it about on me) kind of thing and it was only when I was showing it to my wife when I saw that it had 2 SIM cards available. What the smeg does that mean? Further reading shows that both SIM  cards are free from any service provider (except 3) but both can be used to separate business and friends. But how do they actually work?

I'd be grateful for any help from folk who actually have one of these gizmos

Many thanks,

Steve.
