I am trying to use the Digi XBee 3 Cellular LTE-M/NB-IoT module with a valid SIM. The XBee sees the SIM and can read its phone number, ICCID, IMSI, etc, but it doesn’t seem to want to connect to a network. The Association Indication stays at 23 and I never receive a value for ATRJ except 0. The SIM card is a Verizon SIM card that my company previously had working with a Sierra modem on LTE-Advanced, and I am wondering if that may be part of the issue as well. Any help is appreciated
For Verizon, you must have a special CAT M/NBiOT SIM card. Your standard Verizon SIM card that works on CAT 1 or CAT 4 networks will not work on the CAT M/NBiOT networks.
