In a few cases, the iPhone needs to have its cellular settings updated through a software update from your cellular service provider. Less often, you need to reset or replace the phone's SIM card. It's also possible that there's a problem with your cellular service plan. Before changing any iPhone settings or performing more time-consuming troubleshooting tasks, some simple steps may quickly resolve the problem.
If those don't solve the problem, move on to more advanced potential fixes. Make sure the phone is not set to Airplane Mode. Airplane Mode disables cellular and Wi-Fi service. The phone is in Airplane Mode if you see an airplane icon in the upper-right corner of the iPhone screen, where the signal strength bars usually appear. Toggle cellular data off and on again. Sometimes, especially when you are on the edge of a service area or you lost service and should be back in service, switching your cellular service off and then on again fixes the problem.
If it's on, toggle it off and back on. Make sure you're within a coverage area. If you're deep inside a building, underground, or in a rural area, you may not have service in that location. Check for signal strength bars in the upper-right corner of the screen. Restart the phone. Like toggling Airplane Mode, completely restarting the iPhone might wake your cellular service and return it to normal operation.
Turn on Wi-Fi Calling if you have poor service. If you find that you regularly have poor service or no service somewhere that you spend a lot of time, such as your home, enable Wi-Fi Calling on your iPhone. This is a great solution if you move to a new house or apartment and find it's in a cellular dead zone for your wireless provider.
If you live in a cellular dead zone, consider purchasing a signal booster for your home, which amplifies the cellular signal so you can use the iPhone normally. If an update is available, you'll see an option to update your carrier settings. Contact your carrier to: Verify that your account is active and in good standing. Make sure 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.

Since I have installed IOS 14, my iPhone XS has been restarted for many times now just to temporarily solved my issue - my phone crashes and no network provider detected even the network signal strength is excellent.
Is there an easy way to switch back to IOS 13 for the mean time? Posted by Luemar. Posted by Alouchee. I am facing the same issue as well on my XR and it is frustrating to have to restart the phone all the time.
