MX4pro unable to connect internet

my Meizu mx4pro can not connect to internet though my devide has signal and “3g” icon on status bar.
please help me solve this problem…
my fw: 4.5.7A


@quocnam906 more information please, is it new is it old? Did it ever work did you root your phone? Are you sure that your phone supports the 3G bands you need?

Meizu MX4 Pro

After upgrade i had the same issue. You have to create manually your APN’s from Settings-Networks

@quocnam906 I have the same issue and can not fix by changing APN. Would you please help how to fix?

Looks like your connection to Meizufans was lost, please wait while we try to reconnect.
