Those who use Appointment SMS just create a (free) account and proceed to buy credits that will be used for the delivery of the SMSes.
Reminders are scheduled using a web-based calendar, and you are actually allowed to create message templates that you can use and reuse as many times as you want afterwards. Besides, the application can keep track of all the customer replies that have materialized, so that you can track attendance levels very easily. And these customer replies can be received for free – you can get them in your inbox, and save not only costs but also time.
