Due to increased costs imposed by terminating carriers outside the US, you may pay a higher cost for international calls that terminate using dialed digits or other routing codes reserved for terminations on a mobile or like service in the called country or area. The table below identifies countries and the associated dialed digit detail for countries where AT&T does or will very soon differentiate mobile and similar terminations with different rates on many services. This table below will be updated periodically to keep this information as current as possible for your use. However, this information changes rapidly and the list below accordingly may not to be comprehensive, and does not detail all mobile digits in all countries. In addition, imposition of increased costs for such terminations may occur on very short notice, so that there may be a lag between when the higher rate begins to apply and updates to the table.
