I dont’t have a problem, just wanted to share this with the community.
We use SImcom modules for LTE, and we work with the Verizon network. Our devices using the Cat-M1 network, and when using this network the command CREG will always show connection denied as it is not for Cat-M1 network.
I’m still working on it, but at this stage, if you are on Verizon Cat-M1 network with registered devices you can connect easily.
