Hi lads

After reading some of the posts on here about ppl not using a punting phone but using there registered phone to call on. I am going to get a phone sim for punting with.

When I asked about getting a sim only from three I am being asked for ID and proof of address. Obviously I don't want to give this and have the phone number linked to me at all.
How did everyone else get their punting SIM cards without having to give over any private details.

Thanks
