Review: Nokia Lumia 810 for T-Mobile USA
The Nokia Lumia 810 for T-Mobile is a solid choice for a mid-range smartphone. It may not have a high-definition screen, nor the very fastest mobile processor, but it makes good use of the tools it does include.
The hardware might be a wee bit on the blocky and spartan side of the design equation, but it is solid, well built, and all the features and buttons work properly. The radio and calling performance was quite good, though battery life could have been a little bit better. The communications tools of the 810 are as good as any other WP8 smartphone.
For media fanatics, the 810 has plenty of avenues through which content can be purchased and consumed. Perhaps the only real negative thing I can say about the 810 is the inconsistency of the camera (which in reality wasn't all that bad).
If you're a fan of Windows Phone or are simply looking for a change, the Lumia 810 is an excellent alternative to the Android devices available from T-Mobile.
