it is a little strange 3 offering free sims, but thanks for the link. its good to have a few spare!
I partially agree with you Nadz and HiPD, but actually '3' have been offering free SIM's for as long as I can remember!
It has really been funny watchìng A1ia5 asking about this on the 'no longer nifty forum', and even a moderator like webKami giving him wrong answers!
The '3' store on their website have been selling a SIM for £9.99, with £10 credit included, for at least the last year, and you can also get a free SIM, for a £10 top up, in a '3' store also.
The only thing that is new in this offer, is that the current one does not require any compulsory top up. (Ideal if you have a number to port in, for 3's free £10 credit!)
