No, that's what I thought at first, but actually OP is gaming his/her carrier:
Vodafone has a promotion where it offers you 2Mb for every
call you give or receive, that is over one minute long.

- daveloyall 12y agoOk, now I see your point. However, I think that you can't negotiate a 56kbps link ( http://en.wikipedia.org/wiki/V.90_%28recommendation%29 http://en.wikipedia.org/wiki/V.90_%28recommendation%29 ) over a cell phone. Ordinary copper telephone service has enough bandwidth to transmit a full range of audio signals, in fact more than the voice can produce or the ear can hear. Modems exploit this fact. But cell phones employ lossy compression, and if I understand correctly, one of the "first things to go" are the higher frequency noises. Why transmit what the ear can't hear? Oh, somebody smarter than me has addressed this question: http://superuser.com/questions/748154/use-a-smartphone-as-a-dial-up-modem http://superuser.com/questions/748154/use-a-smartphone-as-a-...
- SixSigma 12y agoAh yes, I had forgotten about that. I seem to recall that older ones had modem functionality, I certainly recall having a fax feature at some point.
