Ensure Airplane Mode Is Disable
If Airplane Mode is enabled on your iPhone or iPad, the cellular radio, the wireless transmission functions, Wi-Fi, and Bluetooth would be turned off and you are not allowed to use them.

To disable Airplane Mode, you can swipe up from the bottom of your iOS screen to open the Control Center. Then find out the Airplane Mode icon to turn it off.
Update iOS to the Latest Version
Apple would release the new iOS version every year to fix some bugs or update the functions of the system. If you are running the old version of the iOS, you should try to head to "Settings > General > Software Update" to check and update it to the latest one.
However, if you find out that the issue occurs only when you upgrade the iOS to the latest version, e.g. iOS 11. That is very frustrating. But it can be fixed. You are recommended to use FonePaw iOS System Recovery, which is an effective tool to help fix the system issues without any data loss.
