Matt, I did see that thread about the SIM and APN details, and have no doubt that the modems will work. The trouble is that our Verizon rep (as of January 2023) does not see the EnviroDIY modem IMEI numbers in their device database, therefore they will not “activate” them on our plan. We have SIM cards operating on the Verizon network now using the Digi modems, and we plan to keep using those SIMs with the EnviroDIY modems if they ever get added to the device database. Do you have a contact at Verizon that was able to activate the EnviroDIY modems on your account? Maybe if I talk to that person I can get further than I did with our rep.
