Saya cuma nak bertanya kenapa saya tidak boleh connect 4G untuk tel xiaomi

Ada sesiapa boleh tolong

I in setting, select preferred network type = PREFER LTE. for 4G coverage area. For non 4G coverage area or if data become noticeably slow, I just select PREFER 3G in setting. That's just how I did. Any better way? anybody?

Kawasan tu ada Coverage 4G tak?
