Sorry for the late reply .
Just FYI: My BigBonus 35 comes with 6GB + extra 2GB free and daily 2GB .
Plus every month I get 2-3GB Loyalty data (but sadly it will be consumed first) .
Previously I was using Cili Padi 35 (then downgraded to 28

), then I figured: Why not go for BigBonus 35, for multipurpose usage- FB, YT, Roblox, browsing, etc.
I was attracted to the 1pm-7pm bonus hours

but it seems pretty much almost useless when Free 1GB is activated.
Thats where I also switched from Best to Live, to gain that 2.5GB weekly Video, though I know its not sufficient, but meant to cushion the YT usage, before it bites into the main data.
At the same time, I control the YT time usage for my kids - Not to save data, but as a form of discipline.
Maybe I should had stayed on Cili Padi from Dec till now, since schools gonna reopen on 20 Jan (provided dont have sudden MCO 2.0) . But I decided to try first BigBonus.
About the Unlimited,
I also wished I get Unlimited 3mbps through BOS (Box Of Surprise) but sadly, no luck. Only offer RM 1Gb for RM 1 or once, I got 2.5Gb for 2 days for RM 1.50.
I asked Digi CS about Next 35, and they said its not a permanent promo, so that puts me off.
So for now, if comes to unlimited, me and my wife , being me using Yoodo , and wife has Hotlink Unlimited (plus she sub to Hotspot add on) will help with any of the YT and/or Roblox usage.
So for now, as an effort to minimize the main data, I will have to rajin2 redeem the Free 1GB every morning.
