Update. Verizon last night made them all not work again. So we must update the remaining to Hologram

Update: Last night at midnight, Verizon changed their code again and now those units work again. We did not get to all of them to convert to Hologram yet.

Does OTA work at all?

I am glad to hear that you managed to get it up and running Jeff Tuctronics .

Seems like these devices were physically accessible so you managed to reprogram it otherwise now way to bring them back online since due to offline OTA will not have worked either.

We were using Verizon SIM firmware for the Nordic module. Instead, we had to program Hologram SIM firmware into the module to put the modules back into service.

We fixed the issue by reprogramming the modules to accept Hologram SIMs. Problem was definitely Verizon code update as response from TCP/IP server client handshake from Verizon is now different. Specific example; the socket number returned is different since July 26. I thank you so much for your response as it got us thinking along the right solution.

You should check with Verizon directly. Also, I think you meant "they are using Verizon SIMS" not firmware, right?

I hope they not blacklisted the devices or something.
