What if I change my local or long distance carrier to a provider other than AT&T?

AT&T Unity℠ rate plans require that you maintain qualifying AT&T services, including an AT&T Business Unlimited Long Distance calling plan.

If you make a change to your account that causes you not to meet these eligibility requirements, the AT&T Unity expanded calling feature will be removed from your wireless rate plan, and calls to AT&T and wireless phone numbers will be billed at normal airtime rates. Wireless from AT&T will send you a text message letting you know that the AT&T Unity unlimited calling feature has been removed.
