Netgear M5 MR5200 no data network connection after factory reset

[jovdew]

Dear all,

I am having a Netgear Nighthawk M5 MR5200 in use. All fine till this morning when I performed a factory reset. After the reset: no data connection. 

The sim card is fine - tested and ok. Yet the device just does not connect to the data network.

What can I do?
