I lost my unlimited data plan with my current upgrade from an Android 2 to an Windows HTC 8x phone, and know I'm noticing I have to pay mega bucks to stream videos and use apps. I currently pay for 6GB, because I went over 4GB last month, but, I'm not sure if that's enough. What's the standard usage for streaming video and app usage? I've used the data calculator and it says I need 16GB...? Is that right??? Any suggestions???
