Hi Ed, My name is Tuan :-) Thanks for your reply, but I still confuse on username/password portion, what does it for? For connecting to operator's modem ?
I don't have any idea on how data calls are established end-to-end. Where does ppp play its role? Do you have any doc or URL regarding it ? I did the following commands but nothing happend: ATE1 AT+CFUN=1 AT+CPIN="yyyy" AT+COPS AT+CBST=0,0,1 AT+CR=1 ATDxxxxxxxxxx where yyyy is my PIN and xxxxxxxxxxx is another phone number. After last command I also repeat some AT+CEER to check but it reports "no error" as: AT+CEER +CEER: 0,1,1,255,no error With the first 4 ATs, I can make a voice call successfully.
