We installed a G3 modem (with SIM Parker installed) on a customer's machine and we activated the Proemion service as in all other cases. All worked well for about a year; suddenly the service was interrupted, and Proemion warned us that there is no "data plan" for the embedded SIM, inviting us to choose a suitable one. It is not clear to us why the modem worked for a year without a specific "data plan" for the SIM and then suddenly it was blocked. Was there any error in the initial modem settings? In the software there configuration of the modem (through IqanRun) maybe we missed something?
