Im with my A55 and everytime I register *123#, it says MMI error. I cant also call through my phone so what i do is i transfer my sim to other device before i could make a call and register to a load. Help me 🙏
Dapat ang sim mo marami, pag mahina signal nung isa dun ka kung may problema yung isa dun. Ka mas maraming network mas masaya kailangan mo lang load monthly ng regular load para sigurado active ang sim ng di masira ❤
