Authentication is used by some network operators to
identify the mobile phone connecting to their GPRS
network. There are different methods, or protocols,
for doing this.
Normal : PAP (Password Authentication Protocol).
The user's username and password are transmitted
over the network in an unencrypted form.
Secure : CHAP (Challenge Handshake
Authentication Protocol). The user's username and
password are never transmitted over the network.
None : No authentication is required by the network
operator.
