Most modern ROMs come with support for non-Google geolocation providers. On these systems UnifiedNlp can be installed as a user app to replace the network location provider. It acts as a middleware for various plugins aka backends, it does not provide any location lookup itself. For further information please refer to the https://f-droid.org/packages/com.google.android.gms package and the <a href="https://github.com/microg/android_packages_apps_UnifiedNlp/blob/HEAD/README.md">README</a>. To be able to use this package, you will either need the <a href="https://repo.xposed.info/module/de.r3w6.xposedunifiednlp">XposedUnifiedNlp module</a>, or your custom ROM must have org.microg.nlp added to the list of network location services, otherwise https://f-droid.org/packages/com.google.android.gms would be more suitable for you (provided that you do not have GAPPS installed on your system). After installing you have to reboot your device, install a backend service and activate/configure it in the app settings. After this you can use UnifiedNlp by activating network-based geolocation from Settings -> Location: You need to select any mode but "device only".
