Send 150 Free SMS Per Day

This service lets you send 150 free SMS every day. The SMS can be maximum of 470 characters, which is the longest offered by any such service. It also supports Flash SMS which appears directly on the phone's screen without having to open it from the Inbox. The best thing is that it is completely free with no advertisements inserted into the SMS you send. Just go to Whozzat.com and register your mobile number for free. You can also register through facebook and provide your mobile number. A verification code will then be sent to your registered mobile number, which you must provide in the next step to confirm and complete the registration process.

You can also send Group SMS. The Phonebook option lets you store mobile numbers and assign them to groups. You can choose the numbers individually, or simply choose a group to which you wish to send the Group SMS.
