In order to make SMS a more sustainable service, we made changes to it as of May 2019.
Change in SMS access
SMS Applets created by customers of the IFTTT Platform will remain unchanged. These SMS Applets are ones that you simply turn on rather than create from scratch, and they show a by the Applet creator.
Applets created using the New Applet tool will no longer provide SMS as a trigger or an action. These SMS Applets will be transitioned to use Mobile Notifications going forward.
Transitioning to Mobile Notifications
Existing SMS Applets made using the New Applet tool, or enabled from user-published Applets will be transitioned to use Mobile Notifications, powered by the IFTTT app. If you don’t have the IFTTT app, download it today in order for Mobile Notification Applets to work.
The SMS service isn’t the only way to send yourself notifications. Browse here for alternatives.
