The Portable Hotspot works with any Wi-Fi-enabled device, such as laptops (e.g. Windows & Mac), smartphones (e.g. iPhone, Android, Blackberry, Windows Phone) tablets (e.g. iPad, Samsung Galaxy, Kindle), and anything else that can connect to Wi-Fi (e.g. game consoles).
You can connect between 5 and 10 different devices to one Portable Hotspot depending on the model.
Please note that the connection speed will be shared among each device connected, so having five or ten devices connected at the same time could result in a speed slowdown.
