We hat payments used to require a Chinese bank account, so we're essentially inaccessible to foreigners. This is secondhand knowledge, I've never used it, but I have heard this has changed. Perhaps since the account was created while this restriction was in place, the option was never enabled?

It's still not possible. If you have a foreigner WeChat account it's possible to enable the pay feature, but not possible to sign up for it without a Chinese bank card.

Thanks for the correction, I had either misheard or had been misinformed.

The wallet option only exists if you have a Chinese Wechat account (using a Chinese phone number).

It also appears if you somehow end up with a positive balance (e.g by receiving a red packet). I haven't tested whether you can actually spend that balance without having linked a Chinese bank account, though.

Yeah I could see the incoming red packet but i couldn't accept it, Eventually the transaction just voided itself. This was 6-8 months ago.

I have tested the red pockets but I couldn't actually receive them. It's been year back or so.
