I bought the HTC One Google Play Edition because I wanted an unlocked phone for when I travel overseas. I am a longtime T-Mobile subscriber and after getting the GPE I immediately noticed that it would not connect to the 4G network very reliably. Thinking this was a possible local network issue, T-Mobile loaned me a T-Mobile version of the HTC One to use side by side. In most cases, the T-Mobile version had good or full 4G connectivity, but the GPE version did not. When it does not, it gets very slow 2G service.
I am able to get 4G about 1/3rd of the time but I can be sitting right next to someone with T-Mobile HTC One or a Galaxy or iPhone and they have full 4G service.
T-Mobile says that the unlocked phones are missing some code that only their phones have. I don't know if that is a line of BS or not, but I am hoping someone on the forums can tell me what is up before I start complaining more to the CEO of T-Mobile.
We can absolutely see how this can get confusing and frustrating, and the information provided by T-Mobile, Google and HTC on the matter doesn't always make things clear either. In the end it basically comes down to the incompatibility of what radio bands the HTC One Google Play edition supports and the radio bands that T-Mobile is operating its network on. Read along after the break for a complete explanation.
