Picture this: you are on a road trip, your phone signal disappears, and suddenly Google Maps refuses to load. Without a signal, most navigation apps go blank — but it does not have to be that way. Google Maps has an offline mode that lets you download a chunk of the map to your phone in advance, so you can navigate perfectly well even without mobile data or Wi-Fi. Here is how to set it up before you need it.
Why Download Maps for Offline Use?
Offline maps are useful in more situations than you might think:
- Travelling abroad, where mobile data roaming is expensive
- Driving through rural areas with patchy signal
- Going somewhere with no Wi-Fi and limited data allowance
- Anywhere you rely on a specific route and do not want it to disappear mid-journey
Downloading the map in advance means you have turn-by-turn directions, street names, and business locations stored right on your device.
What Google Maps Offline Can and Cannot Do
It helps to know the limits before you rely on offline maps:
What works offline:
- Turn-by-turn driving directions
- Street names and address search within the downloaded area
- Basic business locations (name, address, hours if cached)
- Walking and cycling directions
What does not work offline:
- Live traffic updates (you need a signal for these)
- Public transport timetables and directions
- Searching for new businesses or real-time opening hours
- Street View
- Sharing your live location with others
How to Download an Area for Offline Use on iPhone or Android
- Open Google Maps on your phone. Make sure you are connected to Wi-Fi before you start — offline maps can be large files and will eat through your mobile data if downloaded on a cellular connection.
- Tap your profile picture or initials in the top right corner of the screen.
- Choose Offline maps from the menu.
- Tap Select your own map.
- A blue rectangle will appear over a map of your current area. Pinch and zoom to adjust the area you want to download. You can cover a city, a region, or an entire country — but larger areas use more storage space.
- The app shows you how much storage the download will use. Typical areas range from a few hundred megabytes to over a gigabyte for large regions.
- When happy with the area, tap Download.
- Wait for the download to finish. Keep the app open and stay on Wi-Fi during this step.
How to Name and Manage Your Offline Maps
Once downloaded, the map is saved and ready to use. You can manage it by going back to Profile > Offline maps. From here you can:
- Rename the map to something memorable, like “Scotland Trip” or “Spain Holiday”
- Update the map (Google Maps offline maps expire after 30 days — the app will remind you to update)
- Delete old maps you no longer need to free up storage
How to Use Google Maps When You Have No Signal
Once your area is downloaded, using it offline is exactly the same as using it normally:
- Open Google Maps — it will show the downloaded map even without signal.
- Search for a street or address within your downloaded area and tap Directions.
- Choose Driving or Walking and tap Start.
- Turn-by-turn navigation will work using your phone’s GPS, which does not need a data signal.
Important: GPS itself does not need mobile data or Wi-Fi — it uses satellites. What needs a signal is loading the map tiles. By downloading them in advance, you have everything you need stored locally.
How to Download a Specific Location Quickly
There is a faster way to download a smaller area around a specific city or place:
- Search for the city or place in Google Maps.
- Tap the name of the place at the bottom of the screen to open its information card.
- Scroll down and look for the option that says Download offline map (this appears for many cities and towns).
- Tap it, confirm the area, and tap Download.
Tips and Common Mistakes
- Download before you travel, not at the airport. Do it at home over a stable Wi-Fi connection while you have time. Airport Wi-Fi is slow and unreliable for large downloads.
- Check you have enough storage. A large area like all of London or all of a Spanish province can be 500MB–1GB. Go to your phone’s Settings and check how much free space you have before downloading.
- Keep maps updated. Offline maps expire after 30 days. Enable auto-update in Settings > Offline maps to let Google refresh them automatically over Wi-Fi.
- Download a slightly larger area than you think you need. If your plans change and you end up 20 miles from your expected route, you will be glad you have extra coverage.
- Do not rely on offline maps for public transport. Bus and train times are live data — offline maps cannot help here. Download a timetable app separately if you will be using local transport.
Alternatives to Google Maps for Offline Navigation
Google Maps is the most widely used option, but it is not the only one:
- Apple Maps (iPhone only) now supports offline map downloads in recent iOS versions. Go to Settings > Maps > Offline Maps.
- Maps.me: A free app designed entirely around offline maps, with detailed coverage of walking trails and rural areas that Google sometimes misses.
- HERE WeGo: Free, works offline, popular with travellers who want detailed European road maps.
Frequently Asked Questions
How long do offline maps last before they expire?
Google Maps offline areas expire after 30 days and need to be updated. The app sends you a notification when an update is available. If you are travelling somewhere specific, download or update the map the day before you leave.
Can I still use the app normally when I have signal?
Yes. When you are connected, Google Maps uses live data as normal. The offline map sits in the background and only takes over when no signal is detected.
How much storage do offline maps use?
It varies enormously by area size. A single city might be 50–150MB. A large region (like all of Southern England or all of a European country) can be 1–3GB. Check the size estimate before downloading and make sure you have enough free storage.
Can I download maps on mobile data instead of Wi-Fi?
By default, Google Maps only allows offline downloads over Wi-Fi to protect your data allowance. You can change this in Settings > Offline maps > Allow download over mobile data, but only do this if you have an unlimited data plan.
Does offline navigation drain my battery faster?
GPS navigation uses battery whether you are online or offline. Bring a car charger or portable battery pack for long journeys, as running navigation for several hours will drain most phones significantly.
