I had a thought that is most likely not possible but wanted to ask anyways. is it possible with proper equipment to send an internet signal into one cell phone and transmit it to another via calling to allow the other phone(assumed is out of data range) and recieve data via an app that listens to the call for the data recieved and sends data back? I'm sure it would be slow but might allow you to Google something when you are roaming. my first thought of this would be a dongle that converts cat 5 to rg6, hard wire the rg6 into a phones hardware, and have the same thing on the recieving phone if for instance you lived where there was no internet and could plug a cat 6 into your phone from your PC.
