Why your HTC One Google Play Edition has poor connectivity to T-Mobile 4G
The answer is really quite simple. T-Mobile relies on two pipelines. The 1900MHz band is usually reserved for 2G EDGE. The nation's fourth largest carrier also connects using the 1700MHz/21000MHz combination known as AWS. As T-Mobile rolls out its LTE service, it is moving HSPA+ to 1900MHz and taking away some of the connectivity that was used for EDGE. That leaves AWS bands available for LTE service.
Now, because the Google Play Edition of the HTC One is not carrier branded, it does not include the AWS bands for HSPA+. Thus, the bands available for the HTC One Google Play Edition might be T-Mobile compatible, but here is where you need to follow closely. In those areas where T-Mobile is using 1900MHz not only for EDGE, but also for HSPA+, the HTC One Google Play Edition will work just as well as a T-Mobile branded HTC One. That is because the Google Play Edition of the HTC One comes with support for the 1900MHz band.
On the other hand, if you're in an area where T-Mobile is still using 1900MHz exclusively for EDGE, and the AWS bands are used for HSPA+, your Google Play HTC One is going to provide a very unstable 4G experience. If that is happening to you, let's hope that T-Mobile will soon move over HSPA+ to 1900MHz in your area, or expand its LTE coverage.

This is a poor excuse when you consider that the Google Play edition of Samsung's Galaxy S4 has support for T-Mobile's AWS bands. Or am I missing something?

Another HTC mistake, should have included enough bands for all the carriers it would be used on.

This affects everyone that has a Tmobile phone from the past few years, as none of them have 1900mhz support for HSDPA+. Basically you either had 850, 1900, 2100mhz for Europe and Att, or 850, 1700, 2100 just for TMob. Wasn't until around last year that anyone had all 5 bands (900mhz for a few areas, not sure about 1800mhz for 3G).
What it means is, if you get LTE in your area with tmob, you are SOL and need a new phone.
