This sim has been working perfectly for the past several months, then on day it got “deregistered” and I cannot do anything to get internet back through the cell modem. I’ve tried the sim in both a GL-X1200 with a EP06-a and an EC25-AF as well as a GL-X750 with a EP06-a. All to no avail. I have tried the sim in a verizon hotspot and it works just fine, so not sure if verizon has now banned Quectel modems or something.
