Sending 100% Free SMS Worldwide through CallWave using Yahoo Widget seems to be limited now. When I first discovered this service, I was able to send unlimited SMS. I guess when it became popular, they had to have some kind of restrictions to prevent abuse. Just like what happened to ICQ SMS service many years ago.
My brother recommended me a website which is able to send unlimited FREE SMS, ANYTIME, ANYWHERE. The only catch is that you and the person you want to send SMS to(recipient) must be a member of the website. A simple 3 minute signup is all it takes to start sending free SMS.
mobiK, the website that allows you to send free SMS from either an Internet Browser or a mobile phone to most world destinations. You need Adobe Flash player in order to load the mobiK’s SMS sender interface on your browser.

mobiK is able to provide free SMS because they’ve partnered with selected sponsors in a number of world regions. Each message you send is appended with an “ad tag” from their sponsors.
One very useful feature on mobiK is that you can add your friend’s cellphone number into Contact. To send message to multiple recipients, simply drag or double click the contacts that you’ve saved, type your message and click on the Send button. In just a few seconds, all your friends will receive your message.
Sometimes when you send an SMS message you will get the response “Blocked. No ad sponsor“. mobiK will only deliver SMS to the regions supported by their advertising sponsors. If there is not a sponsor in the region where you are sending your SMS, the message cannot be delivered.
If you go through mobiK FAQ’s page, it is quite outdated. mobiK has updated their website to version 2 and a lot has changed. When I use mobiK about 2 months ago, I can only send SMS. Now, I can even collect “K” points to redeem free stuff by inviting friends to join mobiK, completing surveys or enter competitions. One of the prize is invite 50 friends and get a $50 iTunes gift certificate!
Before the update, when you use mobiK to send a text message to your friend, your friend wouldn’t know that it’s coming from you. You’ll have to make sure that you identify yourself in the message. Now mobiK has updated their system and it shows your cellphone number instead of the word “Mobik”. There is no need to guess which of your friend sent this SMS to you anymore! Moreover, having your number displayed allows your friend to easily reply your message without keying in your number.
