here in the northeast, I have been with 3 network for 9yrs now but my wife and daughter are on orange network. My contract expires in 2 weeks but the same tarriff on orange is more than double monthly cost. OH wants me to change so the kids can have me as their free "magic" number to phone me whenever they want at no extra cost. Reviews seem about the same for good and bad points. I have never been with orange and have had the odd loss of signal with 3 but expect this with any network I guess.
Opinions on which network please
