- A simple setting adjustment, such as Airplane Mode or carrier settings, can cause service outages. In some circumstances, your iPhone's cellular settings must be modified via a software update from your cellular service provider. The **[SIM](https://answers.mindstick.com/qa/95588/how-do-i-fix-mozilla-firefox-issues-or-problems-with-some-simple-steps) card** on your phone has to be reset or replaced less frequently. It's also conceivable that your cellular service plan is malfunctioning.
- Cellular and Wi-Fi services are turned off in Airplane Mode. If you notice an aeroplane icon in the upper-right corner of the iPhone screen, where the signal strength bars usually display, the phone is in Airplane Mode.
- Switching your cellular service off and on again will sometimes solve the problem, especially if you are on the edge of a service area or have lost connection and should be back in service. Make sure Cellular Data is turned on in **Settings > Cellular.** Toggle it off and back on if it's on.
