Support Activities

Although eBill enables you to perform most billing self-service activities independently, there may be times when you need to contact a specialist. Contact these support specialists:

• Company Administrator (aka Telecom Expense Manager or TCM): First check your Profiles & Permissions settings to ensure you have the correct permissions needed to perform the task at hand. If not, contact your Company Administrator for approval.

• Chat support is available for personalized real-time assistance Monday through Friday, 8:00 a.m. to 8:00 p.m. Eastern Time.

• For corporate accounts, your dedicated AT&T Business Care Manager should be your first and primary point of contact when you need assistance with Premier Online Care support and training.
