My SIM won't read. I plug it in the sim tray and it shows that it reads the sim but it says no network after a time and shows two signal statuses even though I only have one sim inserted. It fluctuates between reading the sim and having signal, and having no service while showing that there are two sims inserted.I already used this SIM before and it worked. It started doing this yesterday. I can't use my phone properly.
I tried inserting a different carrier and it worked fine
What is wrong?
I'm using a ZTE Axon 7, which is supposed to be compatible
