Post-Warranty Service

If you need service on your telephone after the one-year warranty period, here’s what you do:

If you bought your telephone from AT&T or if you bought it from an Authorized AT&T Dealer, and you also signed an AT&T post- warranty Maintenance Agreement, call the Helpline. Your post- warranty Maintenance Agreement entitles you to service calls with no additional charges for parts or labor.

If you bought your telephone from AT&T but you did not buy a post- warranty maintenance contract, call our Helpline for service charges and assistance.

If you bought your telephone from an AT&T Authorized Dealer but you did not buy AT&T post-warranty service, call your Dealer for assistance (or call our Helpline).

Important Notice:

We expect your telephone will work well for you for many years. However, we do recommend that you buy an AT&T post-warranty Maintenance Agreement if you are concerned about the expense of repair or replacement of your telephone after the one-year warranty period. See your AT&T Representative, your Dealer, or call us toll free at 1 800 247-7000 if you would like to talk about the coverage and price of a Maintenance Agreement.
