# How do I get a phone call when my app is down?

> Use an on-call service that calls you. With Pagerless, add the SDK (or run npx pagerless connect), add your Twilio number, and install the iPhone app. If your app goes silent, crash-loops, returns a burst of 5xx errors or payments fail, you get a push, then a call after 5 minutes.

1. **Add Pagerless to the app** Run it in your repo:

   ```
   npx pagerless connect
   ```
2. **Add Twilio** Paste your Twilio account SID, auth token and number in Alerts. Calls bill on your Twilio account.
3. **Add your phone** Your number for calls, and the iPhone app for the push that comes first.

The call reads a fixed sentence about the problem and asks you to press 1 to acknowledge. If you don't, your backup is next.
