use android T-Mobile mobile internet like a vpn for other phones, so it could be the middleman between me and the web.

Example: I have 2 cell phones cell A with unlimited Tmobile in nevada cell B only use with Sprint in california I need you to find a method of how to connect cell b(sprint) to. cell A(tmobile). so that once cell B is connected to the internet it shows the ip from cell A and in that way all internet traffic with cell B(sprint) seems as if i am using cell A with Tmobile data example: cell b (sprint) ----> cell a (tmobile) ----> internet cell b <---- cell a <---- internet Not sure if i need cell A to work as a vpn, host, to open a proxy server or something else in between in order to use its internet for cell B. I just want the cell A to be as an intermediary to access data on cell B.
