I just received my new D5. It has built-in firmware version 160310. I am facing one strange problem that its detecting the 3g network and internet is also working with mobile network but for text and call its coming ‘Mobile network not available’. I am based out of India and tried on Airtel mobile network. I have tried following things:
- Selected both manual and automatic network selection.
- Did factory reset twice
Would appreciate if anyone could help.
