UWI PilotsmCommunity Skills Bank• President of Claxton Bay Community Council expressed
interest in his community becoming more productive and drawing on its own resources
• Envisioned a paper-based Skills Bank
• UWI proposed an SMS-based mCommunity Skills Bank to provide wide access for all in the community
ECNG SMS• The Department of Electrical and Computer Engineering
has developed a Student Messaging Service (SMS) to facilitate access to key scheduling information
• This service is particularly useful to the many students who do not have Internet access and need, for example, to query exam timetable information from off-campus homes

ECNG
Observations• The SMS message format and the amount
of information involved will determine how complex your application is in terms of how it processes incoming SMS messages and generates outgoing SMS responses
• Migrating to full Mobile Internet implementations of these types of applications is straightforward but not as imminent as handset and service costs limit uptake among Caribbean poor
• A full Mobile Internet implementation has the potential as an m-Government service
