To stop iPhone text message alerts from repeating, open Settings > Notifications > Messages > Customize Notifications, tap Repeat Alerts, and choose Never. By default, your iPhone may repeat a message alert if you don’t look at it, which is why the same text can chime more than once.
Quick Answer
Settings > Notifications > Messages > Customize Notifications > Repeat Alerts > Never.
Turn Off Repeat Alerts
- Open Settings and tap Notifications.
- Scroll down and tap Messages.
- Tap Customize Notifications at the bottom.
- Tap Repeat Alerts and choose Never.

You can also choose to repeat alerts once or several times if you want reminders for messages you haven’t seen.
Why a Text Can Still Alert Twice
| Cause | Fix |
|---|---|
| Repeat Alerts is on | Set it to Never |
| Two messages arrived close together | That’s two alerts, not a repeat |
| Apple Watch or another Apple device also alerts | Adjust notifications on the other device |
| A group chat is busy | Swipe left on the conversation and tap the bell to hide alerts |
| A message filter or third-party app sends its own alert | Check that app’s notification settings |
