u guys didn't notice sometimes speedtest is much faster when googling/surfing/streaming slow like a snail doesn't matter whether infinite package or not coz i have both plan...watch youtube full hd also lagging in tv...is there any issue with digi infra?

p/s: compare pc to mobile is not equivalent apple to apple

im using router (e5172) + phone..is it normal from others modem as well if i set "4G only" then cannot make a voice call...if setting automatic and it work fine..but if i set automatic then it goes to 3G...if i set to 4G only the connection speed is fast...anyone have a same like me?

My old modem is doesn't support 4G+ Enable voice over LTE
So I have to set auto because when I received the call the configuration will change from 4G to 3G automatically.
When I hang up the call then it move back to 4G.

Maybe the new model provide a good feature voice over LTE that is the better one.
