Does your phone have a data cap? Are you sick of being
overcharged for non-voice transmission? Do you have an
unlimited calling plan? Then this option is for you.
By calling your home land-line and using your home
computer
to retransmit data over the internet your smart-phone
can
keep
at least a minimum of internet connectivity at all
times
without exceeding your phone carrier's data cap.
Alternate configurations include cell-to-cell +bluetooth
for
those with extra cell phone but no wireless or for
transmitting
data directly between two smart phones.
Can be configured to only kick in after a set per-month
usage.
BONUS: easily direct connection with your home
computer.

The problem is that the data rate on the codec used to
transmit voice over cellular networks is fairly low — around
12 kbit/s. So assuming you could somehow manage to use
the entire range of bandwidth available, your connection
speed would be slightly faster than a 9600 bps modem. If
you're the kind of person who regularly runs into a monthly
data cap, it seems unlikely that such a connection would be
satisfactory. |

I've actually done this, so I have to say it's baked. It was one of my attempts to dodge expensive data fees. Now, I just have a $25/month unlimited plan. I gave up on the idea because the data rate was far, far too slow. It could literally only load two pages without a 20 minute wait: halfbakery and google. However, if you want to try it you can still find a list of dialup numbers and call one of them with your phone. Carriers no longer charge for that because, well, who in their right mind would do it? |
