Here are some tips to stay connected and avoid missing calls or messages on your 2nd Phone Number:

  1. Keep the App Open:  This is the most important step. If you completely close the 2nd Phone Number app, you won't receive calls or texts in real time. You'll only see missed calls and messages when you reopen the app.

  2. Background Refresh (Optional):  While not essential, enabling background refresh can help ensure the app receives messages even when it's minimized. Here's how to enable it:

    • Open Settings on your device.

    • Find "2nd Phone Number" in your list of apps and tap on it.

    • Look for the "Background App Refresh" option and toggle it ON.

Note:  If the Background App Refresh option is inactive even when set to ON for 2nd Phone Number, you might need to enable the system-wide setting first. Here's how to do that:

  • Go to Settings > General > Background App Refresh.

  • Toggle the system-wide Background App Refresh option to ON. This will then allow you to enable it for individual apps like 2nd Phone Number.

  1. Disable Low Power Mode:  If Low Power Mode is enabled on your device, it might limit the background activity of apps, potentially affecting call and message delivery for 2nd Phone Number. To avoid this:

    • Open Settings on your device.

    • Go to Battery.

    • Toggle Low Power Mode to OFF.

By following these tips, you can increase your chances of receiving calls and messages on your 2nd Phone Number app in a timely manner.
