What do you think about a web service, that will allow people send batch SMS to their team / friends over the world?

You open a web page, enter your cell phone # and enter so many other phine numbers you want (event from other countries). then you enter your message and then you click Send. This message will be send to people.

Let's say user gonna pay 1/2/3 $ for this batch send.

What do you think about this?
