WOW a great site for sending free unlimited SMS in india.
There are no restriction like number of SMS sent per day whereas sms.ac dose not allows more than 5 SMS per day.
The SMS delivery works really fast, gets delivered within a second. Compared to other site free SMS sites which takes nearly a minute and some so bad that it takes hours for delivery.
They have a good number of alert services running like birthday, anniversaries, bill payment due dates etc. Some are really crazy.
But they allow us to send SMS only inside India and also restricts us to only 100 Chars per SMS
