Did you know that some public pay phones have built-in TTYs? Local relay calls won’t cost you a dime, including those placed by voice callers to TTY users. Long-distance relay calls may be billed to another number or a calling card at no extra charge.
To make a long-distance relay call from a pay phone, simply say the type of call you are making (collect, calling card, credit card, pre-paid card, third-party billing, or person-to-person), then give the number you are calling.
Note: Collect, third-party billing, calling card, and credit card calls require billing verification or authorization.
