i managed to use alipay tourpass without much issue during my trip to china last month. i linked my rhb credit card to my alipay account and get myself a hk data sim before the trip and it worked perfectly. i top up a few round of my alipay balance during the trip, no issue. only one thing to take note is never try to transfer rmb from your alipay to any local chinese. i bought something from the tour guide and have tried to pay him by transferring bal from my alipay to his alipay. my alipay account got blocked after a few unsuccessful attempts. howver, i managed to call local alipay helpline and got it all sort out in a morning.

identity verification shows "unverified". no, when i said hk data sim i meant i got it while still in msia becos you need a data line to make this ewallet works. btw, i used alipay for hotel accommodation, at shopping centers, supermarkets, convenient stores, kaki lima petty traders. basically 99% of the spending in china i used alipay other than some angpao i gave to china relative in kampung area i used rmb cash. i add rmb1000 while still in msia to the tourpass and made another 2 top up while in china. it all worked perfectly, no error message.

bring a credit card just for emergency purpose. most 4 star hotels, shopping centers and supermarket accept credit cards for payment...

just type china sim and search at shopee...
