Just want to share my experience.

I will be going to China end of this month. For the last 1 week+, I have been trying to register for Wechat Pay and AliPay. I tried a few of my cards on AliPay (TourPass), all of them have been unsuccessful. I received the error related to "High Risk Card...". Then, yesterday afternoon I was messing with the chat bot inside Alipay app. I even typed some curse word like "F*ck you". lol. I didn't know what I did and it was transferred to a real support staff. After chatting, she said someone will call me tomorrow (which is today). I received the call about 2 hours ago. She said there will be an email send to me, and I will need to submit My passport and also the photo of my credit card. I just did that. And hopefully there will be a good news for  the next few days.

Last night, I was playing with the Wechat Pay as well. I selected the region as "China". I was successfully Added my Visa Card there! I tried to top up to the WeChat Pay balance, all my cards will show errors. I believe it only allows top up balance using a China bank card. There is a page which is used to verify my real name identity, I tried to click everywhere, but there is no way for me to submit my passport. So right now, my Wechat Pay account is still NOT verified.

Just now, I tried to purchase the train ticket via "Rail & Flights" inside the Wechat Pay. The first time it failed. The 2nd time, It was successful! I receive the email "Thank you for your using Travelgo.com. You reservation has been submitted.Travelgo.com will attempt to reserve this ticket for you and purchase it automatically when the pre-sale period has begun."

I compare the train ticket price on wechat pay vs trip.com, it is CNY 20 more expensive than trip.com. Anyway, I just wanted to try to see if wechat pay actually works. And it did!

I will know for sure if works when I see my online credit card statement for the next few days.

FYI, I just came back from China. My WeChat pay is garbage. Can not be used anywhere else. I only successfully purchased a train ticker using a travel app inside WeChat. I can't even use it on Didi e-hailing inside the WeChat! I can link the Wechat Pay to Ctrip but I also can not use it to purchase the one day trip tickets!

Wasting so much time in setting up wechat pay and alipay, at last the hard cool paper money is the most reliable. I already cancelled my wechat pay and alipay account!
