I've had pretty crappy reception in my flat with my Orange phone but it's not that great for my flatmate on O2 either. I've just visited my parents' home and my reception was still pretty rubbish and frequently dropped out completely. I used to have an Orange contract when I lived at my parents' and never had reception issues. I called Orange and they said to set the phone to use 2G only (brilliant!) but I'm still getting occasional drop outs and still only 1-2 bars of signal strength according to the meter. How's your reception? EDIT: I should say that my Parents postcode according to Orange has "Excellent" 3g coverage.
