Aleksander thank you for your detailed answer, Devices you have mentioned look like embedded/oem solutions. Do you know of any consumer grade USB modems with SIM hotplug and modemmanager support? You have also mentioned AT commands, are they standard or vendor specific? I think qualcomm modem I've mentioned has serial and recieves AT commands, but I couldn't register in the network with commands I've found on the internet. Regards, Zurab
