Update Carrier Settings

Wireless providers release carrier settings updates to improve how their cellular networks connect with your iPhone. Carrier settings updates may also introduce new features, or fix minor bugs that are interfering with cellular connections.

1. Make sure that your iPhone is connected to a Wi-Fi network, or that Cellular Data is turned on.
2. Open the Settings app.
3. Make Tap General.
4. Tap About.
5. After a few seconds, if a carrier settings update is available, you’ll see a pop-up on the screen of your iPhone which says, “New settings are available. Would you like to update them now?”
6. Tap Update.

Why this works:

The UpPhone recommend that you update carrier settings immediately after they become available because outdated settings may lead to connectivity issues between your iPhone and your wireless carrier’s network.

Some potential issues include having poor service or your iPhone going straight to voicemail anytime you receive a call.
