    let mobile = Platform.OS == 'ios' ? phoneWithCountryCode : '+' + phoneWithCountryCode;
    if (mobile) {
      if (msg) {
        let url = 'whatsapp://send?text=' + msg + '&phone=' + mobile;
        Linking.openURL(url).then((data) => {
          console.log('WhatsApp Opened');
        }).catch(() => {
          alert('Make sure WhatsApp installed on your device');
        });
