functions - Auto copy value from specific user meta field to another field

I'm looking for synchronizing specific user meta field with another one.
ex: Coping user phone number to woocommerce billing phone.
So the admin can only edit one field and the other updates automaticly.
Thank you.

You can simply hook function to sync phone number field as following;

<?php

// HOOK ON REGISTERING NEW USER/CUSTOMER
add_action('user_register', 'mm_sync_phone_number' , 20, 1);    

// HOOK ON PERSONAL OPTIONS UPDATE
add_action('personal_options_update', 'mm_sync_phone_number' , 20, 1);

// HOOK ON USER PROFILE UPDATE    
add_action('edit_user_profile_update','mm_sync_phone_number' , 20, 1); 

function mm_sync_phone_number( $user_id ) { 

    // GET PHONE NUMBER FROM OTHER FIELD
    $phone_number = get_user_meta( $customer_id, 'meta_key_of_other_phone_field', true );

    // UPDATE PHONE NUMBER IN BILLING PHONE NUMBER FIELD
    update_user_meta( $user_id, 'billing_phone',  $phone_number ); 

}

?>

This way every time, whenever admin is going to add or update user/customer from the dashboard, the value of your phone number field will be updated in the other WooCommerce billing phone number field.
