13.1Basic Mode
13.1.1+MIPCALL, Create a Wireless Link
This command sets up a PPP (Point to Point Protocol) connection with the GGSN (Gate GPRS Support
Node), and returns a valid dynamic IP for the Module.
Note: Module can't support TCP/IP stack AT command mixed with another AT command which can
active the PPP or GPRS in parallel.
Module can't support TCP/IP stack AT command when voice call established.

Notes:
The +MIPCALL command does not return the prompt to the terminal until the IP is received from the
provider, or time out has occurred, therefore, no other commands can be issued in the meantime.
The +MIPCALL command does not have a general ABORT mechanism; therefore a command cannot be
issued until the previous command ends.
In case FTP is established and MIPCALL is set to zero, this will close and disconnect the FTP connection.
When a call exists the dynamic IP address will be returned.
For example:
AT+MIPCALL?
+MIPCALL: 1,172.17.237.80
Activating a context can take up to 150 seconds. Deactivating a context can take up to 40 seconds.
If use AT+MIPCALL=1 to activate PDP. The APN must be set by AT+CGDCONT command.
