Do you mean SMS? There's not an app to do that. Only way I can think is to go to txt2day.com from you phone to send SMS to other people. But if you put your phone number in there and they reply, it's going to come back as a text to your phone that you'll have to pay for. unless you don't put your number as the reply, you could just put your email address, and then they'd have to email you a response. of course, then, you might as well just use email, but it is helpful for sending free texts to other people. just make sure you tell them not to respond if you don't want to pay for it.
