In the Breakthrough iPhone app, open Profile → Contacts & Groups → Sharing & reminders. Verify a phone number, then choose either or both optional switches:
Both switches start off. Phone verification and account creation do not enroll you. Notifications become available after sender approval.
By turning on a switch, you agree to receive that type of SMS notification from Breakthrough Calendar. Frequency varies, with at most one early-event reminder per day. Message and data rates may apply. Reply STOP to opt out or HELP for help. Consent is optional. We do not share mobile information for marketing.
Early-event reminders arrive 30 minutes before your configured Day Ends if tomorrow has an included timed event at or before Day Starts. They use your latest calendar sync. You can change your choice at any time.

The optional switches and disclosure appear on the same scrollable screen. They remain unavailable while sender approval is pending.
