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.
So I have modified the library to add support for CGREG, and you can find the modified library at this link.
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.
