紅米note3 全網通 究竟港版同大陸版hardware係吾係一樣

本帖最後由 jimmyboy 於 2016-4-8 17:53 編輯

I would like to know because I want to use the North America AWS frequency band (i.e. uplink band 1700, downlink band 2100). It seems the mainland version would support but not the HK version.

It is also obvious from the specification pages on their respective websites that it shows HK version supports fewer bands comparing to the mainland version. Namely the B4 1700Mhz band is not supported. (That means the 1700Mhz LTE in Japan is not supported too?)

Called 妖米 customer service, they were not able to help to clarify as I expected because of lack of technical know how. Vaguely implying the two phones are different. However, both versions use the same Qualcomm snapdragon 650 chip. How can they be different in hardware and in supporting different frequency bands?

港版


大陸版

通訊訊號係不一樣的,例如大陸版係雙網通,香港就要全網通

究竟港版紅米note3 全網通 sup吾support B4 1700Mhz frequency band?
大陸版 seems would support

You can buy a Chinese 全網通 if you need those frequencies.  I think HK version is 雙網通, which is $100 cheaper in China.

全網通 needs a separate set of antenna for China Mobile frequencies, so its hardware could be slightly different than 雙網通.

Those extra brands (and CDMA2000) are needed for China Mobile.

To my understanding. The hardware is exactly the SAME.  It might be the radio different, and it is a software any flashable.  It has a very very very high chance that you can get full band support like in China after you flashed with China MIUI ROM.

However, if you know how to check the band information on the device, I can help you with it as I have flashed China ROM and now AOSP.

大陸雙網通 uses the MTK X10 CPU instead.
Both the HK and mainland 全網通 use qualcomm CPU

but I notice on the specification pages that 大陸雙網通 supports the same frequency bands as the HK全網通

其實如果國內全網通版本係適用的話,就買國內版本吧,相對港行只差本地保養,以千元手機計影響很少,真係壞左唔維修掉了都只是千多元吧

sorry I don't know how to check band information on the device..

I always prefer the hk version over mainland because it comes with a clean rom with google framework. I just do not trust the stability of those self install google framework on top of  mainland rom plus all those bundled garbage apps that come with it.

I am concerned with the hardware only as I am planning to replace MIUI with other third party rom at last. Who would trust the rom made in communist china? Not only in terms of privacy but also in terms of quality control and user experience.
It is standard procedure that you buy mainland brand smartphone just for the cheap hardware and replace the rom of your choice.
