Mi4 2G network issue

Jan 24, 2013
Hello everyone !

I'm facing an annoying issue with my Mi4, when I want to switch to 2G by hand or when 3G is not available I'm always in "emergency call", now way to have 2G, GPRS or whatever :-(

The Mi2S of my wife is working well (edge logo) but my Mi4 nothing to do ...

Is there a specific thing to setup ?
