I’m sorry. But I didn’t understand how it was. Please give me a ready list of AT commands so that I can enter them and everything will work. Thank you in advance.
Did you read the thread and document?
Yes, I partially read it, but I didn’t understand it. Because we’re running out of time. We bought 200 such modems from you (EM7455), and we urgently need to set them up and fix such problems. Please help!

from below thread, it says you can use AT+COPS in manual mode to choose operator.
Or you can set +cpls to 0, and then modify the +cpol to set the preferred operator list.
