I had difficulties connecting my raspberry pi (tested on 3B+, 4 and 0) using SIM7000, so i purchased a SIM7020e. But this one also have similar connection issue.
I was using a Telstra data package pre-paid sim but after chatting to a support staff from core-electronics, replaced the sim with a “hologram” sim but still have the same issue.
WHAT IS THE ISSUE:
sim seems to be detected alright by the device. The device is unable to communicate with the antenna. I am not yet using my code. Just followed steps in this link:
