Hi  skyethur,

I'm afraid it cannot be changed. The following information is our LTE band surport.

sorry for any inconvenience

4G :
FDD-LTE: (US version)
2100MHz(1)/1900MHz(2)/1800MHz(3)/1700MHz AWS(4)/850MHz(5)/2600MHz(7)/900MHz(8)/700MHz(17)/800MHz(20)

skyethur,

There is no technical reason that band 12 cannot be enabled.  The ZE551KL uses a Qualcomm 615 SOC that supports band 12 and 17. In fact, there are several phones on the market using the 615 that have both bands 12 and 17.  I believe it requires a minor software change.  Band 12 has been "added" to several phones after their initial release.

There are some Phone companies that they convert the Band 17 to 12 or enable band 12 by updating firmware. I hope Asus will look into this since this is US model phone it should support band 12 and 17.

Yes I know some companies they enabled band 12 by firmware update. Let's hope ASUS will look into this matter. I need band 12 to use in secluded area since my provider only use that band in those areas.

I am just hoping it will happen because this phone is a US model it should have band 12.

is ASUS planned to consider this option or it is just left behind? T-mobile is expanding band 12 in rural areas where people go to or drive through when passing those rural highway. I hope asus consider this please.
