i'm using digi on my note 4 in cyberjaya/putrajaya area. call wise no problem at all. no drop call or anything. except for data speed here is super slow between 9am to 6pm. to rectify this i just use GSM where the speed is enuff to stream 360p youtube once in a while. if i use LTE/HSDPA the video could not play at all.

at night, i can get around 21Mbps download speed test.
