GL-X750 - Verizon "sim not registered" all of a sudden

sven7 · 2020-09-01T18:13:12.846Z

Hello -

All of a sudden, the GL-X750 is now saying “SIM not registered” for Verizon. I’ve seen a handful of other posts, but nothing that specifically seemed to solve it. The SIMs were activated by Verizon and had been used in the device for months and working just fine. All of a sudden tho, something seems to have stopped.

Logs look like this:

Any thoughts or solutions I’ve yet to see?
