SMSCluster is an international SMS marketing service that enables users to send bulk SMS to recipients anywhere in the world. It can be used to send alerts, run a marketing campaign, celebrate an event, and perform other mass communication tasks. During development, users can make use of a "simulation mode" to avoid wasting funds on sending test SMS.
The SMSCluster API allows users to send and receive messages as well as check the status of sent messages via REST, SMTP, or SOAP calls. Users can send up to 10,000 texts with a single API request. SMSCluster provides free sample scripts for its API in Java, Ruby, PHP, Python, Perl, and (in the near future) C#.

Though your definition of an SDK may differ, in our world, we define SDKs as platform- specific tools for consuming existing APIs of the sort we list in our API directory. For example, the Ruby SDK for consuming the Twitter Ads API.
