Check your coverage area

- Turn cellular data off and then back on again. Go to Settings, then tap Cellular or Mobile Data. If you're using your iPad, you might see Settings > Cellular Data.
- If you're traveling internationally, make sure that your device is set up for data roaming. Go to Settings > Cellular > Cellular Data Options > Data Roaming.
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:
- Update your iPhone or iPad to the latest version of iOS or iPadOS.
- 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.
