The way that satellites across the world track time was updated on April 6, 2019, which means that phones and devices using older GPS technology may encounter errors in accurately recording time and navigation. The update is called the GPS Week Number Rollover event. It is a global issue, and not specific to Rogers.
This will affect the GPS information on CAT B15, Doro 620 and Doro 626 phones. GPS satellite data won’t be included if you call emergency services using either of these phone models. Instead, cell phone towers will be used to determine your location using a process called triangulation.
