How to turn on the location on iphone

Some apps might not work unless you turn on Location Services.¹ The first time an app needs to access your Location Services information, you'll get a notification asking for permission. Choose one of these options:

• Tap Allow to let the app use Location Services information as needed. 
• Tap Don't Allow to prevent access.^2..

iOS devices might use Wi-Fi and Bluetooth to determine your location. GPS and cellular location are available on iPhone and iPad (Wi-Fi + Cellular) models.

   

How to turn Location Services on or off for specific apps

1. Go to Settings > Privacy > Location Services.
2. Make sure that Location Services is on.
3. Scroll down to find the app.
4. Tap the app and select an option:
   • Never: Prevents access to Location Services information.
   • While Using the App: Allows access to Location Services only when the app or one of its features is visible on screen. If an app is set to While Using the App, you might see your status bar turn blue with a message that an app is actively using your location.
   • Always: Allows access to your location even when the app is in the background.

From here, apps should provide an explanation of how the app will use your location information. Some apps might offer only two options. Learn more about privacy and Location Services.

1. Location Services uses GPS and Bluetooth (where they're available), along with crowd-sourced Wi-Fi hotspots and cellular towers to determine the approximate location of your device.
2. Apps won't use your location until they ask for your permission and you allow permission.
