Combine your billing phone and account phone from the checkout page and all other locations. Since numbers are fully compatible with WooCommerce, this means that we even support its check-in check-in function, and to make it work properly, we must add a “mobile phone number” field in the checkout, and WooCommerce already has a “counter” in the checkout Charge phone number” field, so this plug-in combines the two fields for the registration process during checkout.
