I use @ionic-native/google-maps. Should I enable billing?
@ionic-native/google-maps, which uses Google Maps Android API v2 and Google Maps SDK for iOS, is the same.
@ionic-native/google-maps is still free?
Yes. Since the @ionic-native/google-maps uses Google Maps Android API v2 and Google Maps SDK for iOS internally, it’s still unlimited usage and free.
