I don't do data so I can not test speeds.
BUT make sure you understand how to choose which network you will want to use. T-Mobile and AT&T have different data rates and coverage.
Know where you will be and how the coverage will or will not work for you.

As far as I know, the only place you can choose which network to use in the USA is from the website. Know before you go. Choose before you lose [choice of coverage and rates].
