Send a test notification through any contact method you’ve set up, and check it is set up correctly. The app test fires at the same urgency as a real page, so it also proves that pages get through Do Not Disturb on that phone.
Send a test
- Open User preferences → On-call notifications.
- Find the contact method you want to check under Contact methods.
- Click the bell Send a test notification button on that row.
- For a phone number, choose SMS or Phone call.
- Confirm with Send test notification.
You can also send a test from the mobile app, which goes to that device only.
The button appears on your own verified contact methods. If a row shows Verify, or a label such as Not installed or Phone number blocked, sort that out first and the button comes back.
What each test sends
What the app test proves
We send the app test at the same urgency as a real page: a critical alert on iOS, and your alarm sound on Android.
Send one with your phone locked and silenced. If it wakes you, you’re set up correctly.
Responders in Mainland China should follow Mobile app in China.
If a test doesn’t arrive
App. Work through the iOS or Android notification setup.
Phone call or SMS. If the test says the number opted out, text START to the number you received notifications from. Otherwise see supported countries and Call screening.
Slack or Microsoft Teams. The test is a direct message, so it needs the incident.io app installed for your user.
WhatsApp. Start with Why did verifying my WhatsApp number fail?.
