You can use this to Website Tools > Custom CSS

div.form-block fieldset.phone .field .caption-text {
    font-size: 0 !important;
}
div.form-block fieldset.phone .field:first-child .caption-text:before {
    content: "new country text";
    font-size: 16px;
}
div.form-block fieldset.phone .field:last-child .caption-text:before {
    content: "new phone text";
    font-size: 16px;
}

Thank you so much! It works perfectly!
