I mean network mode choosen by me ' 3g only'. but after some time this setting change into ' lte/3g/2g' mode automatically. this effect net speed as sometimes it shows only edge(2g) signal. I want only 3g mode instead of 4g/3g/2g auto mode
it's because your device doesn't support dual VOLTE,,,, I suggest you to put the SIM that you wanna use for data in slot 1 and then set it to 3g only mode.. try this method and tell me if it worked
