Content Whitelisting

All content should be whitelisted by local operators. If you wish to send to China, please contact our support team with message samples of the content you wish to send.

SMS Type

Binary and Flash SMS are not allowed in China.

Character Support

Arabic characters cannot be supported by Chinese networks. Because Chinese characters are not supported by the regular character set, messages with Chinese characters can contain a maximum amount of 65 (single message) and 62 (multiple messages/concatenated) characters

Maximum Messages

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.


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. Some networks will filter words like Falung Gong, SB, Tiananmen Square. All networks will block messages with a URL.
