Ah OK, so the device is probed and attaches fine.

Seems lile this is the culprit:

> AT+CGDCONT=1,"IP","internet"^M

This command does not return anything for 30 secs, so ppp aborts:

Since I don't have a data connection in my mobile subscription plan, I 
can't verify it, but are you sure the string you send is correct? For 
instance can you verify it from tip, or even Windows' HyperTerminal? 
This string (AT+CGDCONT=1,\"IP\",\"internet\" OK) seems rather weird 
syntax, but I could be wrong.
