How do I use Amazon SNS or Amazon Pinpoint to send SMS messages to mobile phone numbers in China?

Short description

To send SMS messages in China, you must first preregister your message template for each type of message that you plan to send. Then, send your SMS messages with one of your preregistered templates.

Important: If you don't meet these requirements, then the mobile phone carrier blocks the SMS messages that you send in China.
