<p>After update Google Play Services with Google Market, GSM does not have any coverage, and no SIM is present (according to Android).
Mobile is Dual SIM based on Mediatek 6735 with Android 5.1
Uninstalling Google Play Services updates, and rebooting GSM works again.
A possible workaround, reboot with original Google Play Services, and after this install Google Play Services updates.</p>

<p>Google Play Services bug, incompatible device, ...?</p>
