Redmi Note 4 does have dual band, it support both 2.4ghz and 5ghz, just no AC support.
I never paid attention to wifi bands before but have discovered that only some phones, generally more expensive ones, have dual band. If you don't have a dual band phone and your home wifi has both 2.4 GHZ and 5 GHZ, you will only be able to connect to the former which is not as fast as 5 GHZ. The Redmi Note 4 only has single band wifi while a similar phone the Lenovo P2 has dual band. The Redmi 3S has single band while the Redmi 4 has dual band. Curious that the Redmi 4 has dual band while the Note 4 does not.
No 4g tower, 10 May 2017Hi, most of the service providers don't have towers. Everyone use the other company tower by p... moreRedmi Note 4 doesn't support Vodafone's band. Vodafone have 2100 MHz band for 4G. Note4 doesn't have that band which is drawback for Vodafone users. Note 4 supports 850Mhz, 1800Mhz and 2300Mhz only.

I was a Windows Phone users & was looking for a switch to Andriod.
I was very much clear about my new requirements & was will to pay a premium but was not finding a single phone that could come close until I came across Redmi Note 4.
What i was looking for is as follows
1. All Sensors i.e. Proximity, Gyro, Compass, Accelerometer & Fingerprint
2. FM Radio
3. Dual SIM
4. 5" + Screen
5. If no dedicated SD Card Slot then atleast 64GB built in Memory.
6. High Screen Resolution
7. Acceptable Camera Resolution & Performance
8. Big Battery
9. Good Performance
Not believe me, ther is not a single phone other than Redmin Note 4 which satifies these requirements.
And the BONUS i received was a Phone with Infra Red Remote Control. I can now control all my home and office TV, SetTopBox , AC, Projectors etc with ease
And all these at 6 to 7 time less price of premium phone, which do not fulfill all my requirements
Redmi Note 4 is the best.
