TeleFlip offers a service that allows you to get email on your cell phone even if you have a regular, non-smart, cell phone. They do it by converting the email into text messages and then texting your cell phone with the email. While you can't reply to emails using this service, you can stay on top of your emails with a regular cell phone that has no email capability.

The service is totally free. The only cost to you is the costs of the SMS text message. But if you have unlimited texting on your cell phone, this offers a 100% free way for you to get emails sent to your cell phone.
