Use Google Maps in "No Network Coverage" Area

Use Google Maps In a Place with NO Internet Connection.

If you are planning to travel to some place with no network coverage, but still want to use Google maps (without location features) , type “OK Maps” in the search box and the visible area will be saved for offline future access.

It’s far better than just taking a screenshot and save them to view it later, because your saved map lets you zoom in for greater detail. 

Here’s how to do it:

i. Zoom in on a part of a map that you want to save for offline browsing. 

ii. Then, tap the search bar and type “OK Maps” (minus the quotes) 

iii. Press the Search button. 

If all goes well, you should see a prompt indicating that the map is downloading. It will take about 10 seconds, depending on the size of the map you've selected and the speed of your internet connection. Wait for the message that says “The on-screen map area has been cached,” and you’re good to go.
