Samsung Galaxy S III 4G HSPA+ Speedtest: AT&T v. T-Mobile (Video)

While 4G LTE is great on the Samsung Galaxy S III on AT&T’s network, there are times where you either want to use HSPA+ instead to conserve battery life or have traveled or are living in an area with only 4G HSPA+ and not the faster LTE network available. In those instances, customers with AT&T may be asking how fast is their network’s HSPA+ implementation compared to that of T-Mobile? Well, we reviewed the Samsung Galaxy S III for T-Mobile USA and for AT&T and we had also covered how to disable LTE and use HSPA+ on AT&T to conserve power. Now, we’re going to put the two devices running on HSPA+ network technologies to the speedtest and see which network fares better.

Video:

As you can see from the above video, T-Mobile’s implementation of HSPA+ is much faster than AT&T both in terms of upload and download speeds. Additionally, T-Mobile’s latency, derived from the network ping speed from the Speedtest.net app, shows that HSPA+ on T-Mobile also has a lower latency time compared to AT&T’s HSPA+. Lower latency is better as it would allow for less lag, which means that once MMO games start hitting mobile platforms, users can have a better experience there. It’s also beneficial for use with tethering as well if you’re playing an MMO game on your laptop on the go, for example.

T-Mobile 4G HSPA+ network is fast on the download and upload side, beating out AT&T's HSPA+ network, and T-Mobile also has lower latency as well.

AT&T has higher latency, and slower download and upload speeds on HSPA+ compared to T-Mobile's network implementation. Using HSPA+ over 4G LTE does help to save some battery life.

    Im not sure where you are getting that t-mobile has lower latency than ATT?? according to your screenshots:

    Tmobile Ping: 1083ms
    AT Ping: 120ms

    When it comes to ping/latency, lower is better. Here ATT is 9x LESS latent than t-mobile (even though the tmobile throughput up and down is greater)

      Watch the youtube video. On that particular test, the Tmobile latency was 100ms. Tmobile latency can be quite variable.

        The T-Mobile phone was barely getting a signal at all if you watch the video, that’s why it was so varied. Obviously in an area with stronger signal strength, you’ll get better latency.

    I think it all depends on location and available network for the phone..I have a Galaxy blaze 4G (tmobile) and I did my on test using that same app and i was able to get 23.54mbps DL/ 2.94mbps UL with a 64ms latency at home. Yet at work on a different part of town I may manage a to get 5-10 mbps download and 500kbps-1mbps upload…so location definetly plays a part
