I live in the HU15 area (brough just outside Hull) and since around April of this year I have seen a huge deterioration in reception quality at home. Sometimes I have full bars, but within minutes signal is gone completely. Sometimes I have say 2 or 3 bars which should allow me to make a call - but nothing happens, I get a a display saying the call has failed.
Up until April this year everthing was fine, so what has happened? I can't carry on like this much longer!
All of us in our house are on Giffgaff and are experiencing similar issues - so it isn't anything to do with handsets!! A neighbour of mine who is on O2 is experiencing similar problems - which would suggest it's a mast issue?
