'''Solution 1. Restart or Force Restart Your iPhone'''

If your iPhone has no service or keep searching for service after iOS 12 update, you may need have a try by restarting your device to fix it. Actually, many common update problems can be solved by restarting the iPhone. And if restart is not working, you can try a hard reboot here.

* For iPhone X: press and hold the Side Button and either volume button to turn off your iPhone; after your iPhone is completely turned off, press and hold the Top(Side) Button again to restart your iPhone.
* For iPhone 8 or earlier module: press and hold the Top(Side) Button to turn off the iPhone and after your iPhone is completely turned off, press and hold the Top(Side) Button to restart your iPhone.

=== Solution 2. Reset Your Network Settings ===

Apparently, this no service issue is related to network, so you can reset your network settings to see if things go well. Go to '''Settings > General > Reset > Reset Network Settings'''.

=== Solution 3. Check Carrier Settings Update ===

If the carrier operator update their system, you need to update your carrier settings or your it will show no service or searching on your iPhone. Follow the steps to check for your carrier settings update.

Go to '''Settings > General > About''' and if you haven’t updated the carrier settings, you will see an option to update the carrier settings.

=== Solution 4. Take Out Your SIM Card and Insert Again ===

Sometimes, the no service is caused by the SIM card loosening or not being installed properly. So you can remove the SIM card and put it back again to see if the signal is back.

=== Solution 5. Change Voice and Data Settings ===

Sometimes, changing voice and data settings can fix this no service bug. Because some place is out of the coverage of a particular signal type. So you can just change the voice and data settings to see if the service is available. Just follow the steps:

Go to '''Settings > Cellular > Cellular Data Option > Voice and Data''' to change the voice and data signal types.

Change Voice and Data Settings

=== Solution 6. Contact Carrier Operator ===

If your iPhone is no service, maybe it is because the carrier you are using is under maintenance or your account is fees owed. So just contact the carrier to see if your carrier account is out of work.

=== Solution 7. Check Your Coverage Area ===

Make sure you’re in the area of cellular network coverage. Then follow these steps to fix the no service or searching problem:

Make sure your cellular data is on by going to '''Settings > Cellular Data''' and turn on it.

If you are travelling out of state, make sure you turn on data roaming on your iPhone. Just go to '''Settings > Cellular > Cellular Data Options > Data Roaming'''.
