UK Sim Cards

I have two brand new, unused UK simcards I don't need.
Useful if you are going to the UK on holiday as they come with some free airtime.
One extra useful thing about them is that if you put them into different phones, it is free to call other phones on the same network.
Might save you some money.
I'd rather give them away than chuck them in the trash.
Only going to give them to someone who is really going to the UK though.
No resellers.
