ok, here's a quick summary of my experience in upgrading ultimate to ultimate max "premium".
.. was on ultimate RM60.
.. register and subscribe ultimate max for +rm29.90
.. wait 5 days, recd unifi plus box
.. wait 1+ more day to get activation for netflix
.. unifi box doesn't hv netflix in playstore, not licenced, so u can only use on smart TV or phone or pc.
.. u dun need the box for anything if u use smart tv
.. activate netflix on tv with phone QR scan code verification
.. it will ask u if u want PREMIUM 4khdr for +RM10, i did!
.. so, for +RM39.90, u get netflix 4khdr - very nice picture, DD+ audio
.. then, u go to myUnifi app, look for your apps, activate the new apps included in package
.. after activation, u wait for activation one by one for each new app
.. i just recd activation for 1 ap, the rest shud follow within 24 hrs
all in all... takes a week or so... add RM40, u get netflix 4khdr + iqiyi, viu, lionsgate, Siar.
i now have all that on top of disney+ hotstar, bbc, unifitv ++.
for RM99.90, think ok, happy enuf.
gotta spend some money to help ailing economy!

RM99.90 only for this apps. this price not include ur wifi price, right.😁
