Is this service available internationally?

It seems that registration requires a mainland China phone number, and there is no English support. Can you confirm if this service is available for international users?

It can only sign up for mainland China cell phones at the moment, but I asked their customers and they said it will be open to the world in the near future.

I prefer to wait until their support is internationalized before adding this tool.
