In response to the recent earthquake in Haiti, AT&T is supporting efforts to keep our customers connected.
To make this possible, we’re offering our customers unlimited long distance calling and text from the U.S. to Haiti. This offer is valid for all AT&T Postpaid, PREPAID, and Home Landline customers from August 18, 2021 through August 31, 2021.
Customers may still receive alerts during these dates, but accounts will reflect the credits and/or waived voice and text charges.
