How to fix your iPhone 12 Pro when it has no service

Last Updated: November 1, 2022 by Dave Johnson

When your iPhone 12 Pro has no service, there are several ways you can try to fix the issue.

The quickest fixes include restarting your iPhone , turning Airplane Mode on and off, and checking your coverage area.

When you’re in a remote area, it makes sense that your iPhone’s service would be a little unreliable.

However, if you’re in a densely populated area or a big metropolis, seeing the dreaded “No Service” notification on the top of your iPhone 12 Pro screen can be perplexing at best and downright frustrating at worst.

If you find yourself with no service on your iPhone 12 Pro and are unsure how to fix it, there are a few things you can try all on your own before having to head to your nearest Genius Bar for help from Apple themselves.

Here are a few things you can try.

Enable and disable airplane mode

One effective solution to the no service or signal issue on iPhone 12 Pro, is to manually try connecting to the service provider. All you need to do is toggle airplane mode on and then back off so that the device attempts to connect. Oftentimes that’s all that’s needed to reestablish connection with the service provider. It resets the device’s APM-Cycle in case it’s lost connection to a signal tower, by manually disconnecting from the tower and attempting reconnection.

Start by swiping down from the top-right of the screen to reveal the Control Center. Then, tap the Airplane Mode icon and wait 10 seconds before tapping it again.

Activate Data Roaming

If you see the “No Service” error on iPhone 12 Pro while traveling abroad, you probably have roaming disabled on your iPhone. To fix that, go to Settings > Cellular > Cellular Data Options and turn on the switch next to Data Roaming.

You may want to disable roaming when you aren’t actively using the device to avoid excessive charges. However, that shouldn’t be a problem if you already have a roaming plan set up with your carrier.

Turn Off Automatic Network Selection

Manually selecting the correct wireless network can also resolve the “No Service” issue on your iPhone 12 Pro.

Startthe Settings app and go to Cellular > Network Selection.Now, turn off the switch next to Automatic. On the list of carriers that then shows up, pick your cellular service provider.

Switch Between Voice & Data Settings

Switching between your cellular connection’s voice and data settings can “nudge” your iPhone into communicating with your mobile operator.

To do this, go to Settings > Cellular > Voice & Data and fiddle with the available data options (5G, 4G, 3G, etc.) and voice configurations.

Activate Wi-Fi Calling

Did you know weak cellular reception can occur indoors, even with multiple cell towers nearby? The type of construction material that goes into a building and destructive interference from surrounding buildings often cause that. But, if you can get a signal on your iPhone outside, you’ve figured out the problem.

Investing in a cellular repeater is a terrific way to boost weak signals in places you frequent, such as your home. But you can also try activating Wi-Fi calling on the iPhone as a temporary fix.

Go to Settings > Cellular > Wi-Fi Calling and turn on the switch next to Wi-Fi Calling on This iPhone.

Restart Your iPhone

The easiest thing to try (and often the most effective!) to resolve a no service issue on iPhone 12 Pro is to restart your device. If you continue to see the “No Service” error on iPhone 12 Pro, try doing that now.

Start by tapping Shut Down under Settings > General. Then, hold and drag the Power off slider to the right to turn off the device. Once the screen goes dark, wait for at least 30 seconds before holding down the Side button to reboot it.

Force-Restart Your iPhone

If the “No Service” error is accompanied by a system-wide freeze preventing you from rebooting your iPhone normally, a force-restart can help. Press and release the Volume Up button, press and release the Volume Down button, and press and hold down the Side button until you see the Apple logo.

Check for Carrier Settings Update

The “No Service” status error can also occur on iPhone 12 Pro due to issues with the carrier settings on your iPhone. Your mobile operator may have pushed an update to fix that. However, if you didn’t receive an automatic prompt asking you to install it, you must trigger the update manually.

Make sure your iPhone is connected to a Wi-Fi network. Then, go to Settings > General > About and scroll down until you see the details related to your carrier.

Wait for at least 30 seconds. If a Carrier Settings Update notification pops up on the screen, tap Update to apply it.

Update the System Software

Newer versions of iOS can potentially include fixes for known software-related faults that result in the “No Service” status on the iPhone 12 Pro. If you haven’t updated your iOS device recently, go to Settings > General > Software Update and tap Download and Install.

Occasionally, iOS updates can also introduce issues. When that happens, a subsequent update should quickly take care of them. If you can’t wait, your only recourse is to downgrade the iPhone’s system software.

Eject & Re-Insert SIM

Another quick fix involves taking out and re-inserting the SIM card into your iPhone. You can use the device’s SIM ejector tool or a bent paper clip for that. The iPhone 12 Pro have the SIM tray on the left side of the device.

It’s also best to clean the contacts on the SIM card with a soft dry cloth before putting it back inside. You could also try inserting it into another smartphone to rule out issues caused by a malfunctioning SIM.

Set Correct Date & Time

Having the wrong date and time on an iPhone can cause numerous issues with apps and services, including connectivity problems with mobile operators.

To fix that, go to Settings > General > Date & Time and turn off the switch next to Set Automatically. Follow by setting the time on the device manually. Make sure to set it up to match the time zone in your country or region.

Reset Network Settings

Corrupt and conflicting network settings can continue to prevent your iPhone 12 Pro from communicating with your wireless service provider. Resetting them to their default configurations can help.

To initiate a network settings reset, go to Settings > General > Reset and tap Reset Network Settings.

After the reset procedure, you may receive a prompt to update your carrier settings. But most likely, that should happen automatically in the background.

Call Your Carrier

If none of the solutions above worked, try contacting up your wireless carrier for help. You may have an issue specific to your cellular account that nothing but a call to customer support can fix.

Still Getting “No Service” on iPhone 12 Pro? Contact Apple

Most of the time, toggling Airplane Mode or restarting your iPhone almost always resolves the “No Service” issue. However, if even ringing up your mobile operator didn’t do anything to fix the problem, you could be looking at a defective cellular modem or another hardware-related issue. So your next course of action should be to book an appointment at the local Genius Bar.
