Limit Precise Location can make a supported iPhone’s location estimate less precise for a supported cellular network, but it does not stop the carrier from locating a connected device. The control is available only on certain devices and with supported carriers; it does not change app location permissions, Find My sharing, or emergency-call location.
What Limit Precise Location actually does
Cellular networks can estimate a device’s location from the cell towers it connects to. Apple says that when Limit Precise Location is on, “some information made available to cellular networks is limited.” That may reduce the precision of the network’s estimate—for example, from a street address to an area, as Apple describes it. It is not a guarantee that the carrier will only know a broad area, nor does it make the phone invisible to the network.

The control is specifically about information available to cellular networks. It does not switch off the phone’s cellular connection or prevent the network from knowing which towers the device uses.

Carrier support also matters. Apple lists the feature as on by default with A1 in Austria; YouSee in Denmark; Telekom in Germany; Sky in Ireland; AIS and True in Thailand; and EE, BT, and Sky in the UK. Apple also says people using a physical SIM or eSIM from a carrier in the EU or UK can turn it on. Its listed information does not establish availability with U.S. carriers, so U.S. users should not assume the control is supported.
Apple’s device and carrier information can change. If the option is missing, check Apple’s current feature guidance and confirm support with your carrier rather than assuming a different privacy setting will do the same thing.

How to turn it on
- On a supported device and carrier, open Settings > Cellular > Cellular Data Options.
- If you use more than one phone number or SIM, select the line you want to configure.
- Turn on Limit Precise Location. Follow any prompt to restart the device.
In Apple’s UK-localized instructions, the corresponding menus are Settings > Mobile Service > Mobile Data Options. The control is line-specific when multiple lines are present, so check the intended line before changing it.

How this differs from app location controls
Limit Precise Location concerns information made available to the cellular network. The separate Precise Location permission controls whether an individual app can receive a more exact location through Location Services. To review app permissions, go to Settings > Privacy & Security > Location Services, select an app, and review its location access.

| Control | What it affects | What it does not do |
|---|---|---|
| Limit Precise Location | Limits some location information made available to supported cellular networks, which may reduce their estimate’s precision. | Does not prevent the network from locating a connected device or change app location access. |
| App Location Services permissions | Control whether apps can use location information, including whether an app may access precise location. | Do not stop the cellular network from determining location based on the towers the device connects to. |
Turning off Location Services is a broader change: Apple says apps cannot use location through that service while it is off, and warns that some Apple and third-party app features may be limited. It is not a substitute for Limit Precise Location because it does not prevent the carrier network from using cellular connection information.
