13.8.4Notes
Dial-up with PAP/CHAP authentication is not supported on an already active PDP context that was
activated without authentication.
The context identifier <cid> is mapped to 1 if not specified.
The GPRS dial-up command maps to AT+CGDATA="PPP",<cid>.
If FDN is enabled and FDN check for PS data call is supported by the module, to perform a GPRS dial-up
one of the following entries must be stored in the FDN phonebook: *99#, *99*#, *99**# or *99***#.
