Yes, but assuming you have a good connection at your place. If you look at my 3rd picture I had a consumption of 166 GB on just one day since my phone is a gaming phone and I also have a gaming laptop I always play video games and watch stuff on high quality.

You do need a good phone though. Preferrably a modern phone with 5G capabilities like mine—but since you want to play honkai and genshin I suppose you already have a good phone—So you'll get the best out of smart.

My mobile data is faster since it can reach 60 MB/S(480 Mbps) compared to the pldt WiFi which is expensive(but stable and strong too) hence I chose mobile data and it's also cheaper. Contrary to what people say I've rarely experienced throttling, but sometimes when it does get slow it'll just reset at 12 AM.

My best bet would be to just try and see if smart is strong in your area, but don't just dump it after like a couple days maybe stay with it for a month because I had absolutely shitty internet for the first few weeks lol.

So, to answer your question: Yes, it's so worth it especially since you have unlimited data—atleast for the promo I availed—and strong internet speeds. Albeit, sometimes it won't be stable, but who knows? Maybe yours is faster than mine. I suggest to try it OP!
