The Offline Explorer feature lets you download a detailed map of your current region (or destination) along with information on free WiFi hotspots—even when you’re offline.
To use offline maps:
Go to the Account page and select Offline Maps.
Navigate to the area where you want to download WiFi network information.
Tap Download Offline Map.
You’ll see the number of networks available for download; watch an ad to download the map for free.
Once downloaded, the map will be available for 24 hours. To activate the offline map, go to the Explorer section and tap the WiFi icon in the upper-right corner to toggle the map on or off.
