I accidentally stumbled upon this when buying a phone to replace my old NOTE3, I needed a phone that was compatible with China Mobile's proprietary CDMA network. I think they call it TD-SCDMA, only China Mobile is using it..
Answer: bought a NOTE 5 dual sim model from CMHK shop, I use a sim card from CMHK and CSL, but if you don't go to china, I'd assume any dual sim model from other shops may work (?), but dual sim phones are usually only purchased by frequent China, HK travellers, so you are probably only going to find it at the China Mobile, China Telecom carriers.
The best part: NOTE has this program called KNOX which allows you to sandbox a area of the memory and you can password lock or even fingerprint lock (I haven't tried fingerprint, but I use a pretty complex password anyways).
I can install 2x whatsapp, wechat, QQ, whatever, one into the Android client itself and one into the KNOX container itself, you can even run separate Google Play Store. It;s like having two phones in one, set the auto password lock in KNOX to 2 minutes, I think default is 30, of just set it to lock everytime you press the power key to shut off the screen.
oh and dont forget to turn off the alerts on the whatsapp for example inside KNOX, the popup's still show unless you lock in down inside KNOX, default is not locked down IIRC, Happy Hunting and may you always keep your personal punting logs from prying eyes  | |
