Hey, hope you lot can help 
I don't know if this is possible, but is there a SIM you can buy that will let you use all UK mobile networks? The reason I ask this is that I was in the lakes in the weekend and the missus is on O2, she could get perfect phone signal even at the top of Helvellyn, while I am on T-Mobile and couldn't get phone signal once we got off the M6!
The coverage of T-Mobile is pretty poor compared to Vodafone and O2 imo!
Cheers,
Craig
