How to activate cellular XBee 3G if SIM not supplied by Digi?


I have a XBee Cellular 3G (XBC-M5-UT-001) with default configuration settings for which I purchased a Rogers 4G SIM card (activated). Using XBIB dev board and XCTU, I can see in Configuration working mode that I have cellular signal strength (DB = 61) but Association Indication keeps changing between 22, 23, and FF upon successive configuration reads, the end result is no cell network association.
The XCTU window on the left of the screen indicates the XBee’s MAC address, the user manual shows this should be indicating the IMEI?

Does the SMS function work?
