Wouldn't bother with TOR...it's a magnet for surveillance.
I suggest Opera...it has its own VPN, unlimited data and "My ISP sees nussing. Nussing."
In incognito mode, it also automatically erases browsing history (maybe cookies, too - don't remember), and has a built in adblocker, so pages load faster.
Read about it...lots of nice features: http://www.opera.com/computer
