You can import bookmarks sent from MAPS.ME or third party apps if they export bookmarks in KML format:
1. Open shared KML/KMZ file with bookmarks sent by email, instant messenger or cloud storage, for example, iCloud or Google Drive.
Tap the file with bookmarks (KML or KMZ format) → tap Share button in the upper right corner → choose Import with maps.me in the pop-up window.
Tap the file with bookmarks (KML or KMZ format) → choose Open with MAPS.ME in the pop-up window (if you have no other apps that support KML files, the file will be instantly open in MAPS.ME).
Alternatively, you can copy KML files to the app folder. After that, you should open bookmarks menu and press "Convert" button in the pop-up window. Please note: KMZ is a zipped KML file, you should unpack it first before copy to the app folder.
If you have an Android device you can use almost any file manager and choose open kml file with MAPS.ME. Some file managers like Samsung file manager can't read .kml or .kmz files, but you can use other file managers, for example, Total Commander.
2. It will be open with MAPS.ME and you’ll see "Bookmarks loaded successfully!. You can find them on the map or in Bookmarks Menu screen".
