# Notification Troubleshooting

Troubleshoot issues with notifications

## Pre-Checks

A variety of factors may affect your ability to receive notifications from PagerDuty. If you are not receiving notifications as expected, please check the following items first:

- Was Do Not Disturb (DND) enabled on your phone at the time you were expecting the notification?
- For push notifications, do you have any Focus profiles or work profiles enabled?
- Were you in a location with poor cell service at the time?
- Are there any missed calls from PagerDuty in your call logs or voicemail logs?
- Do you have any settings enabled, which would block or silence notifications from unknown numbers?
- Do you have any safety features which would disable notifications on your mobile device while driving?
- Have you configured the PagerDuty app's permissions to allow notifications?
- Have you downloaded PagerDuty’s [vCard](/incident-management/notifications/notification-phone-numbers#pagerduty-vcard)?
- Does the issue occur after restarting your mobile device?

## Confirm the Expected Behavior

There are some scenarios where you may expect to receive a notification, but the criteria for triggering a notification were not met. When this happens, it is expected behavior that you will not receive notifications. Please read [Expected Notification Behavior](/incident-management/notifications/notification-troubleshooting/expected-notification-behavior) for more information.
