Hello alanbama, welcome as a new customer with us! Currently, Wideband Audio has not yet been launched with our carrier. It is best to have the setting off as it will not change the difference in the call clarity while on. We may launch Wideband Audio in the future. For future news and alerts stay tuned here: http://bit.ly/n5snpq
