PDP Context Configuration Exercise
The mobile terminal can transmit and receive packet by connection to internet through an APN,
A set of parameters required for this connection is called PDP Context.
PDP Context Configuration Flow
1. PDP Context Configuration → SIM7070, SIM7080, SIM7090
| NO | Command | Response | Description |
| 1 | AT+CPIN? |
+CPIN: READY OK |
Check SIM Card status |
| – | AT+CFUN=0 |
+CPIN: NOT READY OK |
Disable RF, for Manual APN setting, if needed |
| – | AT+CGDCONT=1,”IP”,”APN Name” | OK |
Set the APN manually, Some operators need to set APN first when registering the network |
| – | AT+CFUN=1 |
OK +CPIN: READY SMS Ready |
Enable RF, End of Manual APN settring |
