SMS Type

Binary and Flash SMS are not allowed in China.

Two messages with the same content cannot be sent to the same number in one day. A maximum of 100 messages with different content can be sent to the same number in one day.

Filtering

All networks in China filter on adult content, gambling, education, migration, financial services & loans, beauty case, cosmetic surgery, healthcare, red timber and alcohol-related content.
