SMS is a convenient, cost effective alternative to
voice messaging. SMS popularity has grown as a result
of:
1.) Cost - SMS is less expensive then the airtime
used for voice calls or web access.
2.) Non-intrusive - messages are received in a discrete
fashion and do not interrupt an individual if they
are in the middle of a meeting
3.) Integration Capabilities - many software programs
can be set up to send text alerts to mobile phones
when urgent conditions exist.
