Hello guys,

I have had the 'communication error' since today.
First i rebooted the device 5 times but the problem came back every time within 30 minutes.

Now i have removed the SIM card and applied some pressure on the circuit board. After that i used a small knife to bend the contacts that connect to the SIM card all a little upwards.

I do not know if it is a coincidence but now after booting the device i have not had the problem since.

Maybe this will work for you guys too.

Good luck.
