Frequent Google Maps users will be pleased to learn the app now supports reliable offline functionality. Whether you’re driving on rural roads without cell signal or want to switch your phone to airplane mode to save battery and reduce data use, Google Maps continues to provide accurate navigation and search results by relying on your device’s GPS, according to Global Traveler testing.
The offline feature, rolled out late last year for both Android and iOS, allows you to download map areas in advance so maps, destination searches and turn-by-turn directions remain available without a cellular connection. Because the app uses the smartphone’s GPS rather than the cell antenna, navigation and route guidance work even when service is unavailable.
There are a few limitations to keep in mind. Offline maps primarily support road navigation, so they are not intended as a detailed GPS tracker for hiking or walking off-road. You must also download the map area before losing service; offline map files can be large, sometimes approaching a gigabyte or more depending on the size of the area selected. Google lets you save very large map regions—up to 120,000 square kilometers—simply by zooming out to encompass the area you want.
This capability is particularly useful for international travelers aiming to avoid roaming charges, and for users in regions with spotty cellular coverage. By preloading the areas you plan to travel through, you can maintain reliable navigation and search functionality without depending on mobile data.
If you plan to rely on offline maps, consider downloading the necessary regions while connected to a fast Wi‑Fi network to avoid large data usage on cellular. Also check available storage on your device before saving extensive map areas, and periodically update downloaded maps so you have current routes and points of interest.
