As similar method to my previous post on sending free text messages through email, AOL Instant Messenger (AIM) supports sending text messages to mobile phones. It’s a great way to send messages without paying an outgoing fee from your own phone provider. Just add a full 10-digit phone number with a + sign in front of it to your buddy list (e.g. +16175551234). All you have to do is send an IM to that “phone number buddy” and the mobile # will get a text message of that IM. Be careful though, don’t send too many.
