Google Calendar’s SMS Notifications Will Not Be Available After June 27th
Bummer. I heavily rely on SMS notifications for important reminders. SMS makes my phone vibrate while regular calendar notifications are silent.
Starting on June 27th, 2015, SMS notifications from Google Calendar will no longer be sent. SMS notifications launched before smartphones were available. Now, in a world with smartphones and notifications, you can get richer, more reliable experiences on your mobile device, even offline.
To receive notifications on your smartphone, you can use the calendar app that came with your device, or install Google Calendar for Android or iPhone. Learn more about notifications.
Note: This change will not affect Google Apps for Work, Education and Government customers.
