So have I mate, there are a lot of mountains up here in Scotland too! A software update today from them has boosted my GPRS signal to work in most problem areas.
Cardsave have offered me £50 in High Street shopping vouchers for every new customer that I put their way and gets signed up. As I said earlier in this thread, I'm not interested in doing this for ANY gain apart from helping out other forum members. I am to be contacted again by their management with details of a block discount for forum members and they are also very interested in becoming forum sponsors. So I suggest that everyone who is successful in signing up with Cardsave, gets the £50 voucher instead of me. I'll have them contact the ones who have signed to do so.
