Personal experiences with MobiMatter "3" (Three HK) eSIM for Singapore, Malaysia, Thailand?

I know that MobiMatter is an aggregator, so I'm wondering if anyone has used the **3 Hong Kong eSIM for any of the countries listed?** For carriers, Singapore appears to use SIMBA and Starhub, while Malaysia has Celcom, Digi, and Maxis.

Even for those who may not have used the specific package for SG/MY/TH, **any experience with 3 Hong Kong eSIMs?** I keep reading so many conflicting reviews about every single eSIM provider (and the bots...!), I'm struggling to choose.

Lastly, I have a Samsung Galaxy phone, which is another factor, as I have heard some of these only truly work on iPhone despite being advertised for both OSes. TIA!
