This block provides a SMS (Short Message Service) service.
Users can decide to have this service by just clicking the "OK" button and once it is activated, user can deactivate it by clicking "NO" button.
This block will support Moodle versions 1.9.6 and onwards. Also it may works with some previous versions with some changes.

Functionality:

1. When the administrator or teachers or any other authorized person upload an assignment or any resource (lecture slides, videos or any other relevant material) or a quiz, this block will notice that.
2. Then it will send notifications regarding those updates to the respective enrolled students via SMS.
3. In order to receive these SMS's, students first have to fill the "mobile no." field of their profile (can be in international format or normal way). Then they must be enrolled in the subjects provided and then have to select the "OK" button of the block.
4. For now only the students are eligible to receive SMS's.
