Your subject mentions a 'PPP' connection.  So I assume you're using a 
modem which uses PPP.  If so, then the user/password exchange is done 
over the PPP link and not AT commands.  You will have to debug the PPP 
connection in order to understand what fails.

The gatchat library actually has a nice tool that might help.  It uses 
the oFono internal PPP implementation and can make basic context 
activations.  See gatchat/gsmdial.c for reference.

The tool also supports PPPdump file output (use --pppdump option to set 
a filename).  You can then view the detailed transaction log with 
wireshark or another protocol analyzer.
