I really like this wifi prepaid device it's good for checking email, and surfing the internet. This is very useful if your NOT in a location of FREE wifi and you need to have access to the internet, but if your looking to down load, video stream, watch movies for hours you will use up your data really fast even if you have 5 G data. The streaming alone will eat up your data and you will need to kick out another $50.00 for 5G of data or more depending on your data plan(their are three plans). This wifi device is ONLY best for checking email or browsing the internet on the go. If you need to video stream for example, go onto YOUTUBE to view video your better off locating a free Wi-Fi network this way you don't have to PAY it's FREE. Other than this it's great and convenient for on the go use.
