Why does my iPhone 8 have no service while other iPhones work fine?

Hi there Gottastaywarm,

If you are having issues with connecting to cellular service on only your iPhone, these specific steps from If you see No Service, Searching, or SOS on your iPhone or iPad (that you've already looked over) can resolve what's happening:

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.

Reset your Network Settings

Go to Settings > General > Transfer or Reset [Device] > Reset > Reset Network Settings. This also resets Wi-Fi networks and passwords, cellular settings, and VPN and APN settings that you've used before.

Update your iPhone or iPad

Update your iPhone or iPad to the latest version of iOS or iPadOS.

Contact your carrier 

Issues with your carrier or account might affect your service. Contact your carrier to:

* Verify that your account is active and in good standing.

* Make sure that there are no outages in your area.

* Check that your device isn't blocked from receiving cellular services and is set up with the right data plan.

Only your wireless carrier can access and manage details about your account:

* iPhone wireless carriers

If this continues after following that and everything looks good with your wireless carrier, contact Apple Support next. They would be the best suited to investigate this further with you. Reach out using this: Apple Support

Take care!

No Service means that your iPhone cannot connect the the cellular network provided by your carrier.

Use one of your other phones to contact your carrier and ask them to troubleshoot the connection to the iPhone 8 from their end.
