seems the orange SIM card should not use “iot.swir” APN.

Thanks for your response. I don’t have this problem on reboot. When I put an Orange APN “orange.m2m.spec”. I can not register to LTE: “RAT not available”. I can register _some times_ to GSM. Power: ON Current Network Operator: Orange F Current RAT: GSM network (LE\_MRC\_RAT\_GSM) Status: Registered, home network (LE\_MRC\_REG\_HOME) Signal: Good signal strength (3) PS: Packet Switched Registered, home network (LE\_MRC\_REG\_HOME) But I can never connect myself. ---

Are you using those wp77 offical fw downloaded from [source.sierrawireless.com](http://source.sierrawireless.com)? ---

Sure, I picked the R13 (Sierra one). Maybe that is not corresponding with an Orange APN ? ---
