Short Message Service messaging is cheap (if not outright free), reliable and compatible with email. Most new phones allow you to send SMS messages to email addresses and not just phone numbers, while you can use the phone companies email to SMS gateways to send email to the handset. Sure there is a character limit (about 250 chars) but for decades people did more with much, much less ("Thnk tlgrph. Stp."). Worst case, send a few messages.
