If you have a smartphone plan that allows Internet usage but charges extra for outgoing text or multimedia messaging, there’s a way to circumvent the messaging charges. Many cell phone plans include an email address that turns incoming emails into SMS/MMS messages on the recipient’s phone. Chad’s News wrote about this back in 2006, but teleflip.com appears to have gone belly-up. In the place of one central service like teleflip.com, the linked article has the SMS/MMS email addresses for various cell phone vendors. It’s a bit complicated, and you’ll have to know your recipient’s provider, but it saves money.
