[Q] Frequency Bands - Padfone S or Unlocked Padfone X? topic

I can't locate any information about the supported frequency bands of the Asus Padfone X, but I did find the Asus Padfone S.

TL;DR - Does anyone know the supported frequencies for Asus Padfone X?

Asus Padfone S:

3G WCDMA: 900/1900/2100 4G FDD-LTE: 700/800/900/1800/1900/2100/2600*

This list seems a bit incomplete - no 2G standard?


Since I am a T-Mobile customer, I need a phone that supports these:

Quote:

2G GSM/GPRS/EDGE: 850/1900 3G WCDMA/UMTS/HSPA+: 850 (CLR), 1900 (PCS), 1700/2100 (AWS) 4G FDD LTE: 700 (Block A), 1900 (PCS), 1700/2100 (AWS)

Since Asus Padfone S does not support 1700, if I purchase Padfone S then I will have to downgrade from AWS to PCS. The problem this has is that there are no PCS LTE towers in my area since it's a metro area that fully supports AWS. I am in a refarmed area that has HSPA+ on the 1900 band now, so I could at least get that, but if the Asus Padfone X supports 1700 then I'd rather buy one of those and unlock it.
