I am sure most of us would have some tried to find a way to send SMS online using some website. At times there were tricks which worked but now even the service provider are smart and have blocked these means of sending SMS so its no more free.
If you have any of your friend in Singapore then you can SMS him from these sites. You have to make sure which mobile connection he is having. If he is having Starhub then just visit Starhub Web SMS enter your name and your friend’s mobile number and start sending him SMS for free.
For Singtel you need to register first. You can visit Singtel Internet SMS register if you don’t have a account and then start sending the SMS.
