The Internet has a new arsenal against the telecoms world; Web 2.0.
With a combination of twitter and either:
Widsets with the twitter widget
a Gtalk account with a mobile IM client like mxit
one can send free sms’s from a mobile!
All you need to do is use the IM client/ widsets widget to send a direct twitter to a friend and he will receive the message as an SMS, thanks to twitter!
