ProxyDroid is your friend. I have the same issue with my carrier.
Set up fake AP and you're set. Look for instructions online for your specific carrier.
Root required!!
I've spent an inordinate amount of time attempting to piece this together now. Sadly, I've yet to figure out how to accomplish what you described here. I've tried fiddling with various combinations of settings in ProxyDroid, to no avail. I've attempted various free VPN and proxy apps as well.:silly:
Right now I am on a business trip away from reliable WIFI, and Solavei has taken this opportunity to reapply it's stranglehold on my data, effectively crippling my productivity and resolve on this trip. :crying:
They added a new option to top off your data plan when it's depleted, but they only offer 500MB/$1O at a time. I've paid an extra $40 in just the past 1.5 hours !
Could you possibly expound on your process a bit? I cant keep up like this any longer...
