Organic Maps, Google Maps and HERE WeGo compared for no-signal travel — private open-source maps, the most complete navigator and solid offline driving.
Roaming abroad can still cost real money depending on your plan, and in plenty of mountains and rural areas there is simply no signal to roam on. A map downloaded to the phone solves both problems, and modern offline maps take less space than people fear — often a few hundred megabytes for a whole country. The two apps below take opposite approaches: the world's most complete navigator with an offline mode, and a privacy-first open-source app built to live entirely on the device. The 2 apps in this guide were chosen for those two philosophies; many travellers end up installing both before a trip.
Organic Maps is the privacy-first offline map: free, open source, ad-free and tracker-free, built on OpenStreetMap and light on storage.
Organic Maps is built for exactly the situation Google handles worst: no signal, no data to spend, and no desire to broadcast your location. The app is free and open source, shows no ads and runs no trackers, and the maps are based on OpenStreetMap data downloaded to the device, so navigation works one hundred percent offline. Files are heavily compressed, which leaves more room for photos, and it is particularly strong for hiking and cycling routes that Google often ignores. The trade-offs follow from that focus: no real-time traffic or speed-camera alerts, no public-transit navigation, and fewer business listings than Google's places database. For getting around outdoors or abroad with privacy, it is the best pick; for the nearest open pharmacy, keep Google nearby.
Google Maps lets you download areas for offline navigation while keeping business search and opening hours, where alternatives go thin.
Google Maps remains the most complete navigator you can put on a phone: voice-guided driving, walking, cycling and transit directions, live traffic with automatic rerouting, Street View and a places database no rival matches. Offline mode downloads a chosen area to the phone and still carries business names and opening hours, which is exactly where most competitors go thin mid-trip. It is the app to use when you need to find an open restaurant in a strange city. The costs are familiar: navigation uses substantial battery and data when online, Google collects a lot of location information, and offline regions occupy space and need periodic updating. For comprehensive point-of-interest data, nothing here overtakes it.

Questions & answers
How do I download a map for offline use?
In Google Maps, search for the area, tap the place name and choose Download offline map, then frame the region on screen. Organic Maps and HERE WeGo let you download whole countries or regions from their maps menu. Do it on Wi-Fi before travelling — country files can run to several hundred megabytes — and update them at the hotel if the trip is long, since roads and opening hours change.
How much storage does a downloaded map need?
It depends on the area and the app: a large city is usually around one to two hundred megabytes, while a mid-sized country can run from a few hundred megabytes to about a gigabyte. Organic Maps is the most efficient because it compresses OpenStreetMap data heavily; HERE WeGo is the largest because it includes detailed navigation data. One or two countries fit comfortably on almost any phone.
Does GPS work with no signal and no data?
Yes — that is the key detail. GPS is a satellite receiver and works identically with no SIM and no data plan; your phone knows its position in the middle of nowhere. What needs internet is fetching the map to draw that position on, which is exactly why downloading the region in advance is enough. Turn on airplane mode outdoors and the blue dot keeps moving.
Which is best for travelling abroad?
Organic Maps if privacy and data use matter, since it sends nothing to any server and works through roaming blackspots. HERE WeGo is the traditional pick for driving, with the most solid offline car navigation. Google Maps wins when you need restaurants, shops and current opening hours, because nobody matches its places database. The practical move is Organic Maps plus a downloaded Google area for the cities.
