There are both single and dual sims versions. Depending on the region and model.

Hong Kong set.

yes, eSim is supported.

So yeah, I'm taking my Buds+ to a Samsung store to claim warranty. The left bud is unchangeable. Searched around and apparently there's a lot of this happening with the original buds.Just a heads up

New owner of Samsung Galaxy S20 Ultra cosmic gray.
Trade in my Samsung Note 10 Plus 256GB Snapdragon for RM1,755.
Mind you that it cannot more fast charge because i use my macbook pro 65W charger to charge it because i'm always with my Macbook Pro with me.
Thus, it create issue to the motherboard in which the motherboard need to be fixed. It is still under warranty but the shop is in Selayang and I'm in Kuching. Since MCO, cannot fly fly no more. Think about cost, future nuisance and potential for the motherboard to be fried etc; just let it go.
So what the heck. Get the S20 Ultra since if anything ada service centre locally. At the same time, since S20 has simcard + esim + memory card; i can put Maxis Wifi sim + DiGi (call only) esim + 128GB memory card.
End up top up RM3,200.00.

So that's my story.

Its actually android face unlock vs IOS. IOS face ID is far more advance because of the security measures involved in the process.
You have to insert a sim card of the same region is from for the first tims first....eg.. If HK set then insert a HK sim card, make a call or two. Then after that only can insert sim cards from other regions.
