If you're on AT&T's 3G network

AT&T is phasing out their 3G network. If you see No Service in the status bar of your device and you have an iPhone 5s, iPhone 5c, or earlier or an iPad 2 Wi-Fi + Cellular or earlier, contact your carrier to discuss your options. If you have an iPhone 6 or later or an iPad (3rd generation) or later, follow these steps:

1. Update your iPhone or iPad to the latest version of iOS or iPadOS.
2. Go to Settings > Cellular. Then:

• • For iPhone, tap Cellular Data Options, then turn on Enable LTE.
  • For iPad, turn on LTE.

If you still see No Service after following these steps, contact your carrier.

iPhone and iPad devices that support 5G networks are not affected by the phasing out of 3G networks.

Restart your iPhone or iPad

Restart your device. If you're not sure how to do this, follow these steps to restart your iPhone or restart your iPad.

Check for a Carrier Settings update

To manually check for and install a carrier settings update:

1. Make sure that your device is connected to a Wi-Fi or cellular network.
2. Tap Settings > General > About. If an update is available, you'll see an option to update your carrier settings.
3. To see the version of carrier settings on your device, tap Settings > General > About and look next to Carrier.

If you insert a new SIM card into your iPhone or iPad, you need to download the carrier settings for your new carrier.

Turn your cellular line off and back on

Go to Settings > Cellular and check to see if your cellular line is turned on. If your cellular line is off, turn it back on. Then check to see if you have service.

If you don't see your cellular line in Settings > Cellular, you should set up an eSIM or insert a physical SIM card. If you're using a physical SIM card, remove the SIM card and put it back in.

If your SIM card is damaged, doesn't fit in the SIM tray, or you transferred your physical SIM card from another device, ask your carrier for a new SIM card.
