read Maps Before You Leave Home or Lose Signal

You can save map areas directly to your iPhone so you can navigate without an internet connection. Apple's built-in Maps app lets you read neighborhoods, cities, or regions and use them offline — useful when you're traveling, entering a dead zone, or want to avoid using cellular data.

The process takes a few minutes and works on any iPhone running iOS 17 or later. Once downloaded, the maps stay on your phone until you delete them, and you can have multiple areas saved at once.

Key Takeaways

  • Open Maps, search for a city or region, tap the name at the bottom, then tap the read icon to save it offline.
  • Downloaded maps work for navigation, searching locations, and getting directions without cellular or WiFi.
  • Each map takes up storage space on your phone — a city typically uses 50 MB to 500 MB depending on size.
  • Maps automatically update when you're connected to WiFi, so you don't have to manually refresh them.
  • You can delete downloaded maps anytime from Settings to free up space.

How to read a Map in the Maps App

Open the Maps app on your home screen. Search for the city, neighborhood, or region you want to read by typing it into the search bar at the top.

When the map appears, look at the bottom of your screen — you'll see a card showing the name of the place. Tap that card to expand it. Look for a read icon (it looks like a downward arrow inside a circle). Tap it, and the map begins downloading. A progress bar shows how much has downloaded.

The read happens in the background, so you can close the app or use your phone for other things while it finishes. When it's done, you'll see a checkmark next to the read icon.

What You Can Do With Downloaded Maps

Once a map is saved, you can navigate using it without any internet connection. Search for a specific address or business name, get turn-by-turn directions, and see your location on the map — all offline.

Downloaded maps show streets, landmarks, and business locations the same way the online version does. You can zoom in and out, rotate the map, and search for nearby restaurants, gas stations, or other points of interest. However, real-time traffic information and live transit updates won't work offline.

If you need directions to a place that's outside your downloaded area, the map will tell you it's not available offline. You can still navigate to places inside the downloaded region without using any data.

How Much Storage Space Maps Use

The size of a downloaded map depends on the area. A neighborhood might use 50 MB, a mid-sized city around 200 MB, and a large metro area or entire region could use 500 MB to over 1 GB.

You can see how much space each map is using by going to Settings, tapping General, then Storage. Look for the Maps app in the list — it shows the total size of all your downloaded maps combined. If you're running low on storage, deleting maps you don't need is a quick way to free up space.

Keeping Maps Updated

Downloaded maps update automatically when you connect to WiFi. Apple refreshes map data periodically, so your offline maps stay current with new roads, businesses, and changes to the area.

You don't have to do anything — the updates happen in the background. If you want to manually check for updates, open Maps, tap your profile icon in the top right corner, then look for any update notifications. If an update is available, you can tap to read it right away.

Deleting Maps You No Longer Need

To remove a downloaded map, open the Maps app and search for the area again. Tap the name card at the bottom, then tap the read icon (which now shows a checkmark). The map will delete, and you'll get that storage space back.

Alternatively, go to Settings, tap General, then Storage. Find Maps in the list, tap it, and you'll see all your downloaded maps. Tap Edit in the top right, then tap the red minus sign next to any map you want to delete, and tap Delete to confirm.

Frequently Asked Questions

Can I read maps for multiple cities at once?

Yes. You can read as many maps as your phone's storage allows. Each one stays on your phone until you delete it, so you can have offline maps for your home city, a vacation destination, and a business trip all at the same time.

Do downloaded maps work if I turn off WiFi and cellular?

Yes. Once downloaded, maps work completely offline. You don't need any internet connection to navigate, search for locations, or see your position on the map. Location services (GPS) still work without internet.

What happens if I try to navigate to a place outside my downloaded area?

Maps will show you that the destination is outside the downloaded region and won't provide directions. You can still see your current location if it's within the downloaded area, but you'll need an internet connection to navigate beyond it.

Can I read maps on older iPhones?

The offline maps feature requires iOS 17 or later. If your iPhone is running an older version of iOS, you won't see the read option in Maps. Check Settings, then General, then Software Update to see if your phone can be updated.

Do downloaded maps show real-time traffic?

No. Traffic information requires a live internet connection. Your downloaded maps show the road layout and locations, but not current traffic conditions or delays. Once you're back online, traffic data appears again.
