T-Mobile 4G Mobile Hotspot Review

Posted: , posted by John V.



After getting things prepared, the T-Mobile 4G Mobile Hotspot is instantly able to connect to the 4G HSPA+ network by simply pressing the power button, which is stated as being able to obtain theoretical speeds of 21Mbps. Using our HP ultraportable laptop and various other Wi-Fi enabled devices, the T-Mobile 4G Mobile Hotspot is adept at keeping things connected to it without wavering in connection amongst the devices.

Testing out its speed prowess, we loaded up Ookala’s Speedtest.net web site to gather the kinds of speeds we’re able to get with it. During peak hours, we manage to get download speeds around 3.04 to 3.41Mbps, with average upload speeds of 1.27Mbps. Later on in the day, we tested out again, but this time around, we were undeniably impressed to get download speeds of 6.1Mbps. In terms of ping, it generally hovers around 113 to 136ms – which isn’t too bad at all with its response.

In real life world usage, such as uploading and downloading files to our FTP server, we’re once again greeted with speeds that are vastly improved versus what we normally see with 3G enabled devices. Specifically, we see speeds of over 350Kbps while attempting to download an 81MB file. Conversely, we’re able to pull out upload speeds of 120Kbps to our server. All in all, we’re satisfied with the results, considering they’re better than those of 3G devices, but it’s still lagging in terms of the results seen with Verizon’s LTE offerings.

Sadly though, battery life is one major concern seeing that it’s able to only dish out 4 continuous hours of juice before being completely dissipated. For a dedicated device like this, it means that you’ll need to bring along its microUSB charger for short trips to keep you working. Furthermore, we constantly find the annoying issue of it disconnecting from the network entirely after a long period of inactivity. The headaches continue because the only way to resolve the problem to get it connected back to the network, is to restart it entirely by powering it off or removing its battery.


One of the focal driving points about the T-Mobile 4G Mobile Hotspot is the simple reason that it’s the carrier’s very first Mi-Fi device, and rightfully so, it’s able to arrive on the scene sporting a favorable unconventional design and decent speeds to appease most people. However, taking into account its $79.99 on-contract and $149.99 off-contract prices, it’s rather on the pricey side of things. Moreover, it doesn’t do justice as a Mi-Fi device seeing that it exhibits poor battery life and frustrating connection drops. In the end, it’s an admirable start, but we’d recommend picking up any of their 4G enabled USB modems if you want to save some cash in the near term.
