support for t-mobile 3g & 4g?

anyone working on facilitating >2g on T-Mobile network with the Xiaomi RedMi Note2?
Per mi.com/note2/specs/ it appears the device will support:
4G Network TDD-LTE (B38 / B39 / B40 / B41: 2555-2655MHz); FDD-LTE (B1 / B3 / B7)
3G network TD-SCDMA (B34 / B39), WCDMA (B1 / B2 / B5 / B8)
2G network GSM (B2 / B3 / B8)
Whereas T-Mobile support site indicates it utilizes these bands:
4G via: Frequencies: Band 2 (1900 MHz), Band 4 (1700/2100 MHz), Band 12 (700 MHz)
3G via: Frequencies: Band 4 (1700/2100 MHz)
2G Frequencies: Band 2 (1900 MHz)

Or for starters does anyone know if this type of mod is even possible given the modem chip used in the device?
