Mobile users in Iran sent 118 million SMS text messages on March 21st, 2007.
This is quite a large number when compared to other, more active mobile markets. I believe the largest operators in the U.S. have gone past an average of 200 million SMS text messages per day. (I do not have the current records for these operators but I believe the number I've given here may still be in the ballpark. If you have a public reference for more current records, please add it in the comment section.)
