Built for T-Mobile's HSPA+ network, the 4G Mobile Hotspot also is compatible with the carrier's 3G (AWS) and 2.5 (EDGE) networks. It supports up to five mobile devices (smartphones, tablets, laptops, etc.) via Wi-Fi and it's capable of delivering 21 Mbps data speeds.
Front and center is a OLED screen that shows the signal strength, battery life, numbers of devices connected, and the network connection type. You'll also notice a 32GB MicroSD card slot for storing data files. The promised battery life is fours hours of continuous use or up to 4.2 days standby time.
Though the Hotspot doesn't look like much from the front, we liked the lime green border around its trim exterior. What's more, the device is compact (3.9 inches long by 2.1 inches wide by 0.54 inch deep) and lightweight for easy portability.
T-Mobile promises that its Rocket 3.0 is the carrier's first HSPA+ product that can deliver data speeds of up 42Mbps. And if you aren't on 4G it also works on 3G and 2.5G.
Other features include a 32GB MicroSD card slot, support for both Windows and Mac, and a rotating USB connector that can fold in when you're on the go. You even get changeable faceplates in cobalt blue, dark violet, and matte black.
The Rocket 4G Prepaid (top) offers the first prepaid HSPA+ data service from a major carrier (it works with 3G and EDGE as well). Clad in a simple white design, it delivers 21Mbps data speeds and offers a 32GB MicroSD card slot.
The T-Mobile Jet 2.0 (bottom) also supports data speeds of up to 21Mbps and includes a MicroSD card slot. You can get it in black (pictured here) or white.
