Offline Maps Are Your Global Backup

The moment you realize you've lost connection is never the right time to start downloading a map. Savvy travelers know that prepping offline maps is as foundational as packing travel documents—it removes friction at every step, from customs lines to late-night hotel arrivals. Think of it as your secret weapon against unpredictable airports, transit delays, and spotty mobile service worldwide.

How to Save Offline Maps

Follow these steps to ensure you always have the maps you need—no matter where you land.

01

Choose Your App

Pick an offline-capable mapping app that fits your needs.

Google Maps is the go-to for most, but Maps.me has stronger offline search. Confirm that your app supports downloads for all your stops.

02

Check Storage Space

Offline maps take up storage—anticipate your phone’s limits.

Maps can range from 100MB (for a neighborhood) to 1GB+ (for large metro regions). Clear space, or use a microSD card if your device supports it.

03

Download the Maps

Download each map area while you have strong Wi-Fi.

In Google Maps: Search city, tap 'Download offline map.' For Maps.me: Download country or region. Include airports, your accommodation, major transit hubs, and backup routes.

04

Pin Key Locations

Save must-visit points—no need to remember addresses on the fly.

Drop pins for your hotel, Global Entry interview site, airport terminals, and attractions, so you can access them even if you lose connection.

05

Test It Offline

Switch to airplane mode and verify maps and routes function as expected.

Open the app, search for your pins, and try route navigation. Fix issues before you travel, not after you land.

Always include your arrival and departure airports—even for connection cities.

Unexpected changes in layovers or plans? Store maps for adjacent major cities if you suspect diversions.

Update Periodically

Maps expire—refresh your downloads every 30 days pre-travel for accuracy.

Use in Airplane Mode

Test routes before your flight or at your gate to be certain navigation doesn't require a live signal.
