Connection issues

Open Faz95210 opened this issue 5 years ago • 0 comments

Hi, I'm currently working on establishing an internet connection with an A9G(V02.02.20180825R) and a China Unicom SIM card. But It just doesn't want to work.

eg: AT+CREG always give me a +CREG:0,1 and AT+COPS=? returns nothing

I tried with my own China Mobile SIM card and I've been able to go all the way to getting an IP, though every HTTPGET I've done so far gave be back an error 400.

Is there an issue with China Unicom on the A9G or do I need to do something specific to work with it?
