So i have a SIM7600 GH module that I am using with an arduino. But I cannot connect to any network. The only thing that worked momentarily was to take out the sim put it in my phone set it as 2g only and then put it back on the sim7600 module. I am currently communicating with the module throgh at commands. The method i mentioned worked but when I disconnected the module from the pc and then power it up again it does not work anymore and i have to repeat the procces of configuring the sim as 2g only in my phone again. This process is really annoying. I have tried a lot of possible solutions and configurations with no luck.
I have tried the following:
Configure the APN manually
Configuring the bands manually
Checked the power
Checked the antennas
Nothing has worked.
Maybe somebody else has a solution?
