Last time this forumer below managed to enrol their MAE card into 3 devices, so it should work for credit cards as well (assuming you are using Maybank). In regards to different country, as long as in the Wallet app you can add a card, you should be able to enrol the card.
My findings from back in January (not sure if it has been revised, need to check with your respective bank), there are limits to how many devices you can enrol your card into.

I've added local bank and Wise card (mine's from SG) into 2 different Apple ID devices before. So it's fine.

Not only HLB, CIMB Sotong bank also still taking their own sweet time to launch Apple Pay

Sotong bank even committed to launch Apple Pay by H2 2023, but now still no news

Hi Everyone. Just wondering if there is any way for us to activate Apple Pay payment in iPhone without double-pressing the physical power button?

I never use the power button on my iPhone (unless I am shutting down the phone or restarting) and would like to maintain it that way.

Eh x jadi bro.. not a single option to add to Apple Pay when i checked in on the iOS app. even tried reinstalling the app.
I noticed the app store listing for MH doesn't list down Apple Wallet support 

I’m having this problem now. Previously I can delete MH Boarding Pass from Wallet, seems like the option is gone now. How do I delete this? Or will it be removed after a certain time?

-edit-

Ok, need to open Wallet App proper. Can’t delete from double clicking the side button. My mistake

Suica card in Apple Wallet can also view card balance, and top up the Suica card using any payment card inside Apple Wallet.
Very sweet Suica indeed.

Also, don't need to unlock, just bringing close is all it takes, and impressively, it even works when the iPhone is turned off!

The suica terminal is on the right so if u’re wearing the watch on left wrist it will be awkward

So i still used suica on express mode with phone when I was in Tokyo

Does uob and rhb card support Apple Pay?

Got many banks support is good but the implementation on some merchant side need to improve IMHO. Last time go Pasaraya want to pay using Apple Pay with watch the counter girl said cannot (got wave machine)...So she called supervisor for help. Supervisor came and told me its bullshit (said since when can pay using watch?)... I could accept if she told here no support Apple Pay but the answer cannot pay with watch ....

Guys I have a question, can a merchant reject payments with Mobile Wallets (Apple, Samsung and Google Pay)?

Yeah I always mentioned paywave as I assume not everyone is tech savvy. But this restaurant server said they explicitly said they do not accept Apple Pay. Can a merchant do this?

Bruh, I literally said that they don’t even allow me to make the transaction. They forced me to use my physical card. Guy knew I wanted to use Apple Pay but said cannot.

i don’t understand why need to use cimb credit card, if you want apple pay, just get hsbc, maybank, SCB card

nowadays it is damn easy to get credit card unless you are black listed.

i have been using apple pay/Wallet a lot recently and omg it's amazingly convenient! Was in Japan and the Suica card is easily integrated. Wise card can be used via Apple Pay as well as my MBB. Issue is my CIMB travel card does not work with Apple Pay, am thinking to apply for another credit card, any recommendations with good perks?

HLB will be a major announcement on July 8th.
It may be to announce Apple pay
