Guess they don't send TCP/IP over it then.

The ratio of effort and gained value doesn't work out here:

Submarine case:
Really huge effort I guess.
Value gained: priceless, because there is no other way to get any
message trough.

Data-over-voice-gsm: 
Effort: huge. 
Value gained: saved about the cost for a very very slow GPRS
connection. Paid instead the cost of a voice call, blocked voice
channel, and so on. <paranoid-mode> Potential legal problems, as some
telcos might take that as misuse, fraud and press charges.
</paranoid-mode>

Put bluntly, even with CDN$0.03 a kb, to make sense you would need the
voice call to cost way below CDN$0.25 per minute to be cheaper in the
bestcase. Not sure even if
this is the case.
