Connectivity and Call Quality
The connectivity for T-Mobile is definitely where it's hit and miss. In certain areas the connection is absolutely fantastic, but in others the signal just dies. T-Mobile's network is not the best out of the U.S. carriers when it comes to range. However, once you're in range and you're in a fairly large city, get ready to take advantage of the HSPA+. HSPA+ is T-Mobile's upgrade to their 3G network, 3.5G in a sense. It's not 4G by any means, it's more of a switch on their current towers that's been turned on to expand their bandwidth. The T-Mobile HTC G2 is the first phone from T-Mobile to be able to use the HPSA+ network.
Currently HSPA+ is the fastest network in the U.S., even beating out the current 4G network that's functioning. As other carriers' 4G networks expand and grow, HSPA+ will seem obsolete, but for the time being, HSPA+ is the fastest network available. This means that downloading items on the T-Mobile HTC G2 is a snap. Watching YouTube videos, browsing the internet, or playing online games is smooth and fast with little to no downtime whatsoever. The only time you'll notice dropped connectivity is if you leave the bigger cities and move out towards the more rural areas. Expect the signal to die out fast once you start going outward. Also, in some buildings the T-Mobile network band cannot penetrate the building, effectively leaving you with a paperweight.
The call quality on the G2 was amazingly clean and clear. A lot of newer smartphones seem to lack in the most important aspect, the phone aspect, but HTC does a great job keeping call quality clear. When dialing others, neither end sounded low in quality and both sides of the line were able to hear each other fine. Even in stereo mode, the voices came out fairly clean and loud and the people receiving the call were able to hear and reply back fine with no problems. HTC has done a fantastic job ensuring that the G2's primary function, that of being a phone, was working correctly and clearly.
