How to get a phone number in React Native?

Question

With React Native, how do you get the current phone number?

On the same lines can I get the username?

Answer 1

You can not. This cannot be done using the public iOS APIs and therefore cannot be done using React Native.

Answer 2

It looks like the react-native-sim library can do this on Android, although as @xanadont mentions, this is currently not possible on iOS.
