NOTE: Due to the frequently changing requirements and message filtering by mobile operators in China, our SMS provider, Twilio, will only send messages to China on a “best efforts” basis. Messages may be delivered with a generic signature appended in the content and/or with arbitrary local phone numbers as the Sender ID.
