I have 2 HSNM appliances and have had problems with one of these when I'm about to exchange the SIM card
I have checked the SIM card that it's working in a mobile phone, and it also works in the other HSNM appliance box
I have tested with another USB dongle
When I change the SIM card it shows up in the system with correct dBm for signaling
When sending SMS the system says it has sendt SMS but nothing arrives
So when setting back the old SIM that works (but is with wrong subscription) , all of the messages seems to be in queue and they arrives
Any suggestions
