Hello, I’ve been having an issue where the MC7455 in my system, when paired with a GlobalSIM SIM card, repeatedly drops its connection to the internet for a period of about 9 seconds after working for a little over a second.
I noticed a similar issue in another post on here and I’ve included the responses my modem gives to the same commands that were requested in that topic.
