Hi, my Global link 520(firmware 2.06) works fine with provided 1nce SIM card but for some reasons it cannot connect to the internet via "custom" LTE-M SIM card. I have changed the APN and there is 99,9% LTE-M coverage and it keeps saying that "SIM Status: Error" I was not able to find what does it mean and I think this is the root of the problem.
Is there any tool or procedure or does anyone know how to debug this error and find out what is wrong?
Thank you, Jiri
