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.
