Nebula FWA 510 and Iliad 5g Not Working, No Card Detected!!

Hello Kay
I have an end for this telenovela.
Yesterday i came back home from holidays from a location near Cagliari, Sardinia island, to my house near Milano, Lombardia.
I've tried both of the two Iliad's sim and they are working without any problem.
My conclusion is that: the base station some how was knowing the sim was inside a router and not a mobile phone and it blocked the connection.

Best regards, Nicolò
