In the following lists are first the Bands and Frequencies supported by the Volla 22, followed by the Band Descriptions (bands, frequency ranges, and global range). The last list is that of the bands and frequencies supported by the US carriers. The US bands are blue to provide a quick visual of the corresponding bands supported by the Volla 22.
Two major bands used in the US are Bands 4 and 66 (1700/2100) and these are not supported by the Volla 22. However, there is wide national coverage of the 700 MHz and 1900 MHz frequencies by the Big-3. On paper, the Volla looks like it should function in most populated areas of the US, but as we know, it is being blocked.
Volla 22 Bands and Frequencies:
GSM/2G: B**-850 / B8-900 / B3-1800 / B2-1900
UMTS/3G: B8-900 / B1-2100
TDD/LTE/4G: B40-2300 / B38-2600
FDD/LTE/4G: B*-700 / B20-800 / B** - 850 / B8-900 / B3-1800 / B1-2100 / B7-2600
*See notes – could be NAR or EU/EMEA
**B5 or B26? Either way it is provided in the US, but in limited areas
