Apple Limits Carrier Access to Precise GNSS Location Data on New Modems

Apple introduced a privacy control in iOS 26.3, restricting cellular networks from accessing high-precision Global Navigation Satellite System (GNSS) location data. This capability, passed via protocols like LPP and RRLP, allows carriers to pinpoint devices with meter-level accuracy, often without user knowledge. The new restriction applies only to devices utilizing Apple’s proprietary modem introduced in 2025.
