“Cell phone text messaging is a convenient way to communicate with someone when speaking on the phone isn’t appropriate. The process of entering a message on a cell phone’s number pad, however, is less than convenient. If your Mac is handy, you can use iChat instead to send messages to your friend’s cell phones,” Jeff Gamet reports for The Mac Observer.
Gamet reports, “Chatting with a friend’s cell phone works just like chatting with someone else on iChat. Their phone even shows up as online whenever it is turned on. Just be sure to keep your messages short because some phones will clip the length to a specific number of characters.”
