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.
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.
