When I insert a sim card in the sim card slot it does not detect it and just says no signal.
I have a x27 unit and in settings the option for sim 1 is greyed out. Only sim 2 can be switched on or off. I had flashed the unit to quad boot as follows:
1. Android
2. Recovery
3. Sailfish OS
4. Debian
In settings I can see the IMEI numbers though.
What should I do? I really need the sim to work otherwise the device is not worth keeping for me.
Please help!
