My T's office (i assume its computerized) sends a text to my cell phone reminding me of the day/time/provider of my appointment two days early (to allow for that time to cancel before the 24 hour limit). I do find it beneficial because I always feel like i'm going to forget what day or what time my appt. is. Also, i schedule my appts a month or more in advance and never know the exacts of my appt just off the top of my head. Its a simple service that I don't NEED but i do find it useful.
