Apparently the Libyan government is trying to get mass SMS messaging going:
Sources on the ground in #Libya: Mass text messages being sent to users in support of #Gaddafi. Those who forward the messages to others are promised phone credits http://fb.me/AtidOJ1G
Twitter 25/02 11.15 ‘Reports from #Libya: Citizens of #Tripoli receiving texts offering 100 dinar credit if they send messages asking people to stay home today’ by @MAQAM.

It's not clear that this is having the intended effect, though, as messages asking people to act as if nothing happened only make sense if you're completely out of touch with the reality on the ground:
So the government is asking people to go back to work, but as I told you I don’t think that will be possible in weeks. There’s so much destruction in the city.
