    The Hologram dashboard should say “Verizon” in some way if it connected to that network.  The Hologram SIMs do work on Verizon, but they nearly always connect to AT&T in my experience.  There was a thread just a bit ago about setting the carrier profiles for the LTE-M XBee3’s , and for the time being we’ve decided that the default of “0/Automatic” isn’t stable on Hologram and we will specifically select AT&T unless it’s known to not be present at the site.

    Changing the setting in profile to 3/Verizon should work, but I’ve found you might need to set it and reset or power cycle a few times before the setting “takes.”  You may also need to clear your “forbidden” list:  https://support.hologram.io/hc/en-us/articles/360035697373-How-do-I-clear-the-FPLMN-list-.  From recent conversations with Hologram tech support they say the u-blox SARA R410M is pretty quick to decide that it’s failed to connected to a network/operator and should mark that network as forbidden.
