Is Amazon video streaming available in Mexico?

Video streaming burns a lot of bandwidth, even more if it is High Definition. 200GB per month is entirely possible (this is what I am currently consuming).

I mostly use Apple TV and Netflix streaming services since I am not in the US and Amazon does not offer their service to Canada (last time I looked). I have not looked into work-arounds that make it appear that I am within the US. Lots of these redirection services exist for web browser Netflix viewing, but not so much for hardware devices like Apple TV.

In general if you want really reliable video streaming and you want to be able to use your internet connection for other purposes at the same time then the more bandwidth the better.

Not only for your Internet provider but also for the WiFi bandwidth. Streaming has a tendency to make the Internet feel sluggish for other users sharing that connection.
