Hello, I am starting an IoT project and I am currently using a hologram Simcard and a SIM800L module. I am having some trouble getting started as I haven’t been able to get my Simcard to connect to the network. I already activated it in the hologram dashboard, when I try to use it with my SIM800L using AT commands I can find that the module can detect a cellular network but I cannot connect to it.
Here is a copy of what I am seeing:
I was only able to upload one image, here is the rest of the log:
