hi, i got a nokia 6280 mobile. and it has been giving me trouble every now and then. it fails to access network sometimes, shows no network access. this happens mostly when i go for a long journey(not sure whether anything to do with it). but it says no netwrok access.
if i try manual searching for network, it shows up a list of service providers, but doesnt get me through them, again says no netwrok access. tried switching on and off, no luck. also tried restoring factory settings and again no network access.
doesnt know what exactly going worng with it. given to nokia shop twice, once they corrected it, didnt tell me what was wrong. second time, it corrected by itself when i reached shop.
anyone any idea what could be wrong.?
