If you’re still relying on Google Calendar SMS alerts to keep you on track, you’re going to need to adopt an alternative. Google has confirmed that it will stop offering this service on June 27 now that “richer, more reliable” options are available on mobile devices.
Google offered SMS notifications for Calendar events before smartphones were commonplace — when there were no mobile apps or push notifications. But now that we have those things, the company no longer sees a need for ageing SMS alerts.
“Now, in a world with smartphones and notifications, you can get richer, more reliable experiences on your mobile device, even offline,” Google says on the Calendar support webpage.
Google points users toward its official Calendar apps for Android and iPhone, but most third-party calendaring apps offer Google Calendar support. Some excellent options include Sunrise, Fantastical, Calendars 5 by Readdle, and Any.do.
There are some exceptions, however: If you’re a Google Apps for Work, Education, or Government customer, SMS alerts will continue to work as normal. Presumably that will change at some point, so it might be good to migrate to push notifications anyway, but for now you don’t have to worry.
