Gmail has done it again. And again and again and again.

And they are now doing it again…

Did you know you can send SMS messages for free from your Gmail Chat window?

In order to do that, click on Settings -> Labs,  and enable the SMS features.

How can it be for free?

The answer is very simple. Google gives each gmail user a qoute of 50 outgoing SMS messages.

Now, for every incoming  SMS you recieve, you will get 5 credits for outgoing SMS. And this is where they make their money. Google has signed revenue sharing agreements with the cellular companies on the incoming SMS. For every SMS message you GET, they make some money.

I still don’t get it why the ratio is 1:5 but I’m sure they have their reasons.

There are plenty of other Gmail Labs feature that make Gmail the BEST email option out there, I promise I will write about it some time soon.
