It took me 20mins for my call to be answered 8am earlier just now.

The cs who answered my call cannot solve the prob on the spot and must arrange a callback for another officer to change ur hp details.

Better setup both : Alipay and weixin pay before travel. Some merchant use diff payment.
Weixin - limited to 3 card (green card)
Alipay - can put more than 3 card. You can set priority payment and rename card. Can get summary of total expenses and category. You can export out as well. (blue card)
There is one time merchant help me to pay from alipay to his wechat (cross payment). If one cc failed, it will help you to failover to next cc. Therefore advice to put more cc inside

Make sure both are verified with passport before travel.

Alipay also can get metro and bus qr for payment. I prefer alipay as more friendly to non chinese people. Weixin sometime in chinese, so i use another phone to do translation. Didi also in Alipay (English)

Bring 2 phones . one for help u to do translation (non chinese). Download the language first.
Use MY roaming so u dont get block on their firewall. No need vpn.

Some tips:
a) Use Amap - navigation (english friendly)
b) Apple Map work. Amap better.

If you know chinese, then no major issue compare to me.

ok, I just checked my hotel booking (through agoda in one KL Hotel) with UOB apps.
I paid in SGD, didn't get 'extra' charges. And i got 12x points.

All my bookings in recent days, i paid in SGD/Thai for with Trip.com, Klook and Agoda.
Also, with Agoda Mastercard link, u have extra discount = discount + more points

Link your UOB PRVI Miles Elite Card to the Grab app on your mobile device. Redeem a complimentary ride home within Klang Valley from KLIA Terminal 1 when you complete 3 overseas transactions.

Promo code: UOBKLIA80

Can I ask is this FCFS? I think I saw some posts earlier that it cannot be redeemed. I used twice in the past, it was OK.

I will use AA this time, so it will land in KLIA2, I guess I need to go to KLIA1 to use this Grab promo?

Ya just done redeemed 300k worth of miles like 24k with 50% rebate really not a bad deal
