You can do one of 2 things..actually 3 things.
1) try and unlock the phone and run cyanogen mod and a custom kernel <----but that requires you know enough about your phone to root and modify your software along with having all the info to do it
2) Try and go on a reliable site to grab another gsm device
3) go to google and get an unlocked nexus for cheap and put a sim in it. https://play.google.com/store/device...k5ODU2NzgwNCJd
or just live with it until you are able to find a work around. I will try and do more research later but right now this is where we are at.
