should be eight problem. ever since data is shared SG/MY. dec went MY no such issue, can even get 5G signal very stable. now set 4G auto, 5G auto, restart phone.....majority of the time is "E". Worst is that try calling also can't work too (becos no VoLTE????).
zero1 with strong 5G signal no problem....
agree speed is not as good, maxis is no longer smooth when going over the weekend
but in term of coverage, should the reason really be on eight end, but then signal wave should not drop till cant get signal
took awhile to hop on the alternate, at least can run smoothly for normal use
