Global Positioning System (GPS) rollover.


On November 2 (and previously on April 6), the timestamp used by GPS satellites will roll over and reset to zero. This rollover happens every 19-20 years and will be the second time this has happened since GPS was invented. Some older devices may lose GPS functionality after the rollover.

This is a worldwide issue that affects certain older devices across wireless carriers and equipment manufacturers, as well as other industries that use GPS products and services.

The GPS rollover will not impact your ability to make a 9-1-1 call on your mobile phone and a 9-1-1 caller’s location information will still be relayed to a 9-1-1 call center, but the location information may not be as precise as a device with GPS functionality.

T-Mobile® and Metro® by T-Mobile have contacted customers who have devices that may be affected by this rollover. If you have an impacted device and don’t intend to use GPS services or functionality, your device will continue to work as it does today and you are free to keep your current device and rate plan.
