As of today, Google Maps is going offline
It is not available right now but soon Android users will be able to use the Google Maps app even when no network or Wi-Fi signal is available.
Users will need to download the area they wish to visit in advance from Google Maps. The bigger the area, the more storage is taken up on your phone, but it does mean you’ll be able to find your way around abroad without the need for paper maps or by incurring expensive data charges.
Even when offline, you will be able to zoom into the area of Google Maps you have downloaded, right down to identifying specific street names. You’ll still be able to use your phones compass without 3G or Wi-Fi too, and so long as you have a GPS connection you’ll also remain represented by the moving blue dot on your map.
