Apple has introduced a new privacy feature in iOS 26.3 that gives iPhone owners more control over how their precise location is shared — not just with apps, but with their cellular carriers, addressing a long-standing blind spot in mobile privacy.
Most users are familiar with controlling app permissions for things like camera access or whether an app can see your GPS location. But until now, there has been another layer of location tracking that operated independently of those settings: the data collected by cellular networks themselves as your phone communicates with nearby cell towers.
How Carrier Location Tracking Worked
Your iPhone’s connection to a cellular network involves a process known as triangulation: the phone continually communicates with multiple towers, and carriers use the strength of those signals to estimate your position. In areas with dense tower coverage, this method can pinpoint you down to a street-level location — even if your device’s own Location Services are disabled.
Unlike app-based tracking, this kind of carrier-level tracking has historically been outside the reach of device privacy settings. Turning off location permissions in the iPhone’s settings didn’t stop carriers from inferring where you are, and there was little consumers could do about it.
Apple’s New “Limit Precise Location” Setting
With iOS 26.3, Apple has added a setting called Limit Precise Location, aimed at reducing how accurately your location is reported to cellular networks. When enabled, this setting prevents carriers from seeing your exact street address. Instead, they will only receive a broader view of your location — for example, identifying the neighborhood you’re in rather than your specific position on a map.
Importantly, this change doesn’t interfere with life-saving services like emergency calls, which still transmit precise coordinates to emergency responders. And it also doesn’t affect features like Apple’s Find My service or navigation apps, which rely on the phone’s own built-in location sharing when Location Services are enabled.
Why the Change Matters
Apple hasn’t offered a detailed explanation for introducing the feature, but the move follows years of scrutiny over how carriers handle subscriber location data. In April 2024, the Federal Communications Commission (FCC) fined major U.S. carriers — including AT&T, Verizon and the merged T-Mobile/Sprint — nearly $200 million for sharing location data with third-party aggregators without customer consent. In some cases, such data brokers even provided tools that could pinpoint mobile phones in real time, raising serious privacy concerns.
That history has highlighted a gap in privacy protections: even users who responsibly manage app permissions had no choice over how carriers tracked and shared their location. Apple’s new setting aims to close that gap, albeit only partially.
Limited Device and Carrier Support
At launch, the feature is limited to devices equipped with Apple’s own advanced modems — specifically those with the C1 or C1X chip. That currently includes just a few models, such as the iPhone Air, iPhone 16e, and the cellular version of the iPad Pro with the M5 chip. Popular devices like the iPhone 17, which use Qualcomm modems, are not supported because Apple cannot control what those third-party chips transmit.
Carrier participation is also limited. In the United States, only Boost Mobile supports the new setting at rollout, while major networks such as Verizon, AT&T and T-Mobile have not yet enabled it. Some international carriers — including Telekom in Germany and AIS and True in Thailand — are offering support, but adoption remains sparse overall.
Android’s Comparable Effort
Google has introduced a similar capability for Android devices through Android 15’s Location Privacy hardware abstraction layer (HAL), which also aims to give users more control over how their location is exposed at the network level. However, like Apple’s implementation, it depends on cooperation from modem vendors, most of whom have been slow to adopt this type of privacy control.
Why This Matters for Privacy
For many iPhone users, the assumption has long been that if you deny app permissions for location access, your movements aren’t being tracked. Apple’s new setting highlights that there’s another dimension: your carrier could already see where you are, regardless of those app controls. While the feature doesn’t eliminate carrier tracking altogether, it offers a meaningful way to limit precision and improve privacy — at least for supported devices and networks.
