TDE-LTE is LTE/4G standard which is used in China by China Mobile.
Meizu in Europe is compatible with FDD-LTE.
Maybe you can’t conect to 4G/LTE because I think MX4 uses 1800 and 2600 frequency.
I also think that 800 is still in testing phase, I red this info somewhere.
The other info about frequencies on the battery is writen in Chinese I think.
M460 and M461 both have the same hardware and both support the same 2G/3G/4G-FDD frequencies.
The only difference between M461-unicom and M461-international is that the M461-international has unlocked bootloader and you can flash any firmware and on M461-Unicom you can only flash firmwares C/U and A but No I-firmware.
