Are there any special calling card rates with the AT&T One Rate® 10¢ Plan?
When you sign up, you can order the AT&T One Rate® Calling Card Plan. It’s great for people who make a lot of calling card calls. You can call anywhere in the United States at anytime for one low rate of 30¢ a minute when you dial the call yourself using 1 800 CALL ATT®. An additional monthly plan fee of $1 applies. Calls placed from a pay phone are subject to a surcharge of up to 56¢ per call to recover fees charged to carriers to compensate pay phone owners for use of their equipment.
