I'm having this strange problem with the network and i don't know whether it's a phone's problem or not. Sometimes the network stops working, even though the bars on the upper left of the screen show it's connected. It results in no access to the network, i can't receive, make calls or use the internet.
Does it sound to be more a problem of the phone or of the network's company?
Whilst presumably in Network mode it is set to "Dual" does changing to "GSM" make any difference with this paritcular provider? Could only suggest trying SIM for another provider to see if your n9 behaves similarly as a process of elimination.
Happy to have helped forum in a small way with a Support Ratio = 37.0
I have a same problem.
I don't think it's sim card fault because it works fine in other phone. But other sim card in Nokia N9 doesn't seem to work sometimes aswell. Same thing, can't call out, text messages don't come thru and can't connect to inthernet but connection bars are high.
What I should do?
