Chapter 12 - Configuring PPP and Cellular Modem
The Access Point Name is the APN of your wireless network. This information will
be provided by the wireless network when you register for data service.
The Dial string is special command to be sent by the cellular modem to the wireless
network to establish a data connection. For GSM/GPRS network, normally it is the
string: “*99***1#”. This command might vary depending on the wireless network.
Please consult the wireless network operator for the correct dial string command for
data service. A regular telephone number is usually not required to connect to a GSM/
GPRS network.
