Hello I'm trying to get internet connection with sim800L and ESP32 DEVKIT.
I bought sim card from T-Mobile. I activated it and put on my mobile phone and everything works well. I tried to use internet and phone call - works great.
After that i connected SIM800L to my ESP32, uploaded code but i cannot get internet connnection.
LED of sim800L is blinking very fast ~ 0.8ms
After many hours of debugging i installed a terminal program for serial communication.
AT - return ok
At+CREG? - return 0,3 or 0,0
AT+CSQ - return 10-15
AT+CPIN? - return READY
AT+COPS=? - return operators included mine opreator - after got my opreator number i was tried to : AT+COPS=1,2,"26002" and AT+COPS=0 but got ERROR response after some time
I was trying also to put another sim card but still no internet connection..
Anyone have some ideas how to solve this problen?
