So after a long and drawn-out process and speaking with multiple CSRs, it seems that WeChat cannot accept foreign credit cards for purchases other than mobile topups. I know several of you have stated you can do it, but all Web research shows it's not possible, and we had 3-4 representatives try to help set it up, only to confirm at the end that it cannot be done.
What cards have you had success using? Maybe it's somehow relegated to a few individual banks?
