Have just bought myself an ipad and am looking at service providers for the sim card. They are all pretty much of a muchness (is there such a word?) and i will only be buying the month long contract but want to get one that has good coverage. I cannot get a signal with my iphone on O2 in Norfolk and have just had a problem with it in Wales as well. My husbands iphone is with TMobile and was using the Tmobile/orange service in Wales but no signal in Norfolk Broads. Anyone got a service that they recommend as pretty much comprehensive or am I just going to have to go on trial & error?
