Why is your iPhone 8 showing no service or no signal?

There are also some cases where a bad SIM card or damaged component is to blame.

Before you start to troubleshoot, try to ensure that the hardware is totally free from any sort of damage. You’ve got a higher chance of fixing the problem if it’s software-related. Otherwise, you will need to take your device to a technician for service.

Aside from ensure no damage to any of your iPhone components, also make sure that your account is in good standing. By good standing means that you don’t have any unsettled balances or any other account-related issues that might have prompted your carrier to disable the account services temporarily. Contact your carrier to verify and/or settle this matter. Also ensure that there are no ongoing maintenance services that might have affected or caused network unavailability at the moment. For ongoing outages, all you can do is wait until it’s over and your network signal should become available again by then. Network services normally resume after that.

When and how to troubleshooting the problem?

Make sure that you are using your iPhone in an area within your network’s coverage. Otherwise, you really cannot be reached and that you have to go back to where there’s a signal from your network tower. If the problem persists even when you’re using your iPhone in an area within your network proximity, then you may go ahead and begin to troubleshoot. Here are your options.

First method: Reboot your iPhone (soft reset) twice or three times.

To make sure that it’s not just a minor glitch, try to restart your iPhone. If you’ve done that already, give it another try. Some glitches require more than one reboot to be rectified completely.

To do so, press and hold the Power or Side button for a few seconds until the Slide to Power Off screen appears. Drag the slider to power off the device completely. After 30 seconds, press the Power or Side button again until the Apple logo appears.

Alternatively, you can do a forced restart. Here’s how:

Either ways can help give your iPhone a service refresh without affecting any of your data and personal information.

While many people have found no luck from installing software updates as they ended up having troubled by post-update flaws, iOS updates always contain fix patches for less-common software bugs that can trigger the no service or no signal error on your device. So it’s still highly recommended to update your iPhone’s software and carrier settings. Here’s how:

  1. Go to Settings-> General-> Software Update menu. If an update is available, you’d normal receive a notification.

You’ll find no button to check for available carrier settings update so all you have to do is stay in the About page for 10 to 20 seconds. If nothing pops up, then your carrier settings are up to date.

Downloading the carrier settings for your new carrier would be necessary if you insert a new SIM card into your iPhone 8.

Fourth method: Reset network settings.

A network settings reset might be the required solution especially if the problem is caused by incorrect or messed up network settings on your device.

This will refresh the Cellular Data function of your iPhone. And here’s how it’s done:

Sixth method: Remove and reinsert the SIM card on your iPhone 8.

It’s possible that your iPhone shows no signal or no service error because the SIM card is dislodged. To make sure this isn’t the trigger, removing and reinstalling the SIM card can help. Here’s how it’s properly done:
