• FDD: B1/2/3/5/7/8/20/28AB

Therefore, it's recommended that you verify the compatibility with T-Mobile prior to making your purchase. I hope this information is helpful. If you have any further questions or concerns, please do not hesitate to ask.

If you connect a Wi-Fi bud to the tablet, the sound will depend on the specifications of the bud. If the bud supports stereo sound, then the audio will be in stereo. If it only supports mono sound, then the audio will be mono. Please refer to the specifications of the bud for more information.
