That's same everywhere. If your phone didn't support local equivalents of VISA, Google, Uber, iMessage, Amazon, ... it's just Mainland China equivalents of services and slightly different implementation of federated login/payment. People tends to assume that the set of brands they recognize is truly universal and global and others are additive, that's not the reality.

There are Chinese regional apk distribution sites for Chinese phones. You don't hear about those(I don't either) because there are near zero communication bandwidth across languages on this planet. That doesn't mean they don't exist.
