Hey there! I'm not too familiar with this phone but when it comes to troubleshooting your signal, I've got you covered. There are only two reasons this would be happening - network compatibility or the device itself. What area are you in? You can either provide a City/State or a zip code. I'll take a look at what frequencies are available then compare them with your device's frequency options.
Just checking in to see if you still need help with this device. Even with this being one that T-Mobile doesn't directly support, we'd still like to help as best as we can. Can you help us out with the questions Amanda asked? Thanks!
As far as I can tell it doesn't matter, I did tons of research and only 1 or 2 providers in all of USA even support the bands this phone works on.
