What is the FOTA sim-pin logic? I have set multiple pin numbers to all FMB920 devices. I want to know if a new configuration(singular) update would affect a unit from being online or not register the new config file. When a new sim with the (pin number activated) is inserted into the device you have to enter the pin on the configurator to enable to save the new config file. My concern is that the FMB920 will look for the pin initially entered in the configurator
