    Hello, I have problems with the signal. When searching for a network, I find it perfectly, but when I select speed 2 g, the smartphone runs out of service, loses the signal. I have a nokia lumia 920. Unfortunately, in my country there is no 3g service, so usually I lose signal. Any solution?

    • This is not the problem in your phone the problem is actually in the service provider. You can check out your Carrier’s customer support that what you should do in this case, as they will guide you what settings you need to do in order to make it working for you. Old Blackberry phones also encountered similar problems in Asian markets.
