@3matija This website is to 100% bullshit.
M578 is public Chinese
M578H is global
Don’t trust random web pages.
If you want to know your model number have a look on your S/N.
If it’s Global it will be xxHxx
If it’s Unicom it will be xxUxx… and so on.
And about bands: All phones support the same bands, on the same firmware. It makes little difference wich one you buy. Enabled bands only depend upon the installed firmware version.
So S/N on my m1 note is xxHBxxxx , so itś unlocked to any mobile carrier ,that supports those 2G.3G,4G bands.
Then you just have to check your mobile carrier signal bands.
isn’t it that, if you bought it from local meizu reseller store or via web, then it should automatically be the xxHxx version, right ?
