It looks like this has been asked several times recently, but how do I connect one of the Digi XBee or XBee3 LTE-M or LTE-CAT1 modems with the hologram network? I have one of each of the 4 cellular modules Digi sells.
For the XBee3’s, I’m seeing exactly the behavior that someone mentioned here: https://community.hologram.io/t/digi-xbee3-modems/2009; the AT&T LTE-M XBee3 module tries for a long time to connect and is eventually denied. The AT&T LTE-CAT1 XBee3 reports “Registering to cellular network” forever.
The earlier Verizon LTE-Cat1 XBee (not XBee3) also reports registration is denied.
The AT&T 3G/2G module connects fairly quickly,
