We are now trying to use hologram sim card to help user get start cellular trip soon, because there are so many carrier in the world inluding 2G/3G/4G/NB/CATM1. Each carrier’s cellular connection is different. We want to try to integrate the connection to firmware. So can you share your code about how to use hologram in your country? Below is my test in China:
CHINA, CHINA MOBILE, GSM
at+set_config=cellular:(AT+COPS=?) //serach net
at+set_config=cellular:(AT+COPS?) //query choose net
at+set_config=cellular:(AT+QICSGP=1,1,“hologram”,"","",1) //set apn name
at+set_config=cellular:(AT+QIACT=1) //active apn
at+set_config=cellular:(AT+CSQ) //query net quality
Because the hologram sim card can switch to the net in global, it can be a good way for user’s first try.
Welcome to share your experience as the format:
country;operation name;net type
Thanks very much!!!
