SMS Notification/Sending Integration...Part 1

Recently i was faced with client request to integrate sms sending to an existing application.
i had not done it before but i knew it is possible.

The application is a web based application hosted by a third party hosting company.

The sms notification to registering clients must
1. send sms notification to clients on successful registration informing them of date of start of service
2. auto send sms reminders to clients some days before start of service
3. auto send sms  reminders to clients some days before end/expiry of service
4. send custom sms notification to selected clients
