Answer 1

Refer to the documentation for configuring phone auth with FirebaseUI: https://github.com/firebase/firebaseui-web#configure-phone-provider

You have the ability to set the default selected country via defaultCountry configuration field, eg:

ui.start('#firebaseui-auth-container', {
  signInOptions: [
    {
      provider: firebase.auth.PhoneAuthProvider.PROVIDER_ID,
      // The default selected country.
      defaultCountry: 'GB'
    }
  ]
});
