Free SMS Starter Pack which contains 10 x SMS Reminder credits when you sign up before Monday 15th December. Never Forget allows you to create reminders for specific dates and times so you'll receive a SMS text and an EMAIL so you Never Forget.
Simply choose the date, time and contents of the message and we'll do the rest. Each message can be up to 140 characters in length which should be more than enough to write the details of your reminder. Reminders are automatically created as a recurring event when entering Anniversaries and Birthdays. You can still receive EMAIL reminders without purchasing any credits.
Google Calendar has free SMS and email notification feature.
