AAAAaaargh you've confused me it doesn't take much!! My samsung has an O2 PAYG sim, the same one that was in my Nokia that you so kindly grovel grovel helped me with. So I think you are saying to try a different network card in the samsung and see if it works and if so it is unlocked??? If this is the case and even if it isn't (!) I'll try it tomorrow and report back, cheers m'dear
