I think 30 days ago my cell automatically update OS 5.1.1 after that my cell shows no SIM card.
Next day i replaced my SIM card and inset my cell then my cell working normally but after 6 hours my cell again shows no SIM card but my SIM working well in other cell phone.
At that my cell shows Service Disabled message on start up.
If I go to Settings - Networks, Mobile Data is grayed out.
Dig deeper to Tethering & Networks, Mobile Networks is also grayed out.
I just did a Reset Factory an hour ago and the problem persists.
It's not the SIM Card since it works well on another phone.
How do I fix this?
