get your own phone number with react-native

Yes it is possible, through the library link

You install it using the commands:

npm i react-native-sim-data
react-native link react-native-sim-data

You import it into your code:

import RNSimData from 'react-native-sim-data'

And you get the data of the SIM by means of the function:

RNSimData.getSimInfo()

The object you get has the following structure:

{
  carrierName0: string;
  displayName0: string;
  countryCode0: string;
  mcc0: string;
  mnc0: string;
  isNetworkRoaming0: string;
  isDataRoaming0: string;
  simSlotIndex0: string;
  phoneNumber0: string;
  deviceId0: string;
  simSerialNumber0: string;
  subscriptionId0: string;
}

To get the phone number it would be:

RNSimData.getSimInfo().phoneNumber0;

NOTE: The number 0 you see in the properties refers to the amount of SIM your device has, if your phone is Dual SIM you can get the phone number of both by changing 0 by 1.
