A map fails you on a trip for two reasons: it is unavailable, or it is in the wrong language for the person you need to show it to.
Download the area before you leave
Every major map app lets you download a region for offline use. Do it at home, because offline maps work with no signal, no data plan and no eSIM activation. That covers the gap between stepping off the plane and getting connected. The gap ends when live transit times and traffic come back, which a downloaded map cannot give you.
- The downloads are large, so use home Wi-Fi rather than a hotel connection.
- They expire, typically after a few weeks. A map downloaded for a postponed trip may be gone when you finally fly.
- Offline maps generally give you the map, search and driving directions. They usually do not give you live transit times or real-time traffic.
The global app is often not the local one
In several Asian cities the best transit data, the most accurate opening hours or the only working ride-hailing integration sits in a local app, and the international app you use everywhere else is visibly worse. Local operators supply their data to local platforms first, and sometimes only to them. Check each destination instead of assuming your usual app wins.
Save the address in local script
A romanised address is frequently useless to a taxi driver. The street name in Latin script may not match anything they read, and transliteration conventions vary.
Save your accommodation’s address in the local script, exactly as the property writes it. Keep it where you can show it without data: a screenshot, a note, or the hotel’s own card in your wallet. This habit prevents more arrival trouble than any app. Do the same for the return, with the airport’s name and terminal in local script.
Screenshot the first route
Take a screenshot of the route from the airport to your first night’s accommodation while you still have a good connection. It survives a dead data plan, a failed eSIM activation and a phone in battery-saver mode, and it takes ten seconds.
How we prepare
We travel on Saily for data and treat offline maps as the backup. Before flying:
- Download the offline region at home.
- Install the local transit app and open it once, so its first-run setup happens on reliable internet.
- Save the accommodation address in local script.
- Screenshot the first route.
Everything else gets solved on arrival, with a working connection.
