Clickatell provides bulk SMS services.
This module provides integration between the clickatell SMS service and the SMS frameworkproject.
This module was original created and distributed as part of the 1.x sms framework project. Since there are many other sms service provides supported by smsframework its seems appropriate to keep the individual third party gateways separate from the core SMS functionality/API's. So as of the 2.x branch clickatell is now its own project.
