A:Answer If -- and only if -- you have a very, very strong 4G LTE signal, you will be able to stream content without delay.
However, you must pay for every GB of data that you use with this device and stream using a LOT of data. Be sure that you understand your data needs clearly before you purchase a data plan. For example, if you stream one HD Netflix movie every night for a month, you could require as much as 100GB of data each month. A 100GB data plan from AT&T costs about $400/month. If you purchase a plan and go over, the overage charges will pile up quickly -- $15-20/GB depending on your base plan.
My advice? Be very careful streaming content using ANY device over a mobile connection UNLESS you have an unlimited data plan. BE ADVISED THAT, CURRENTLY, AT&T WILL NOT SELL YOU AN UNLIMITED DATA PLAN FOR THIS DEVICE.
