Relay SD Telecommunication Relay Service is a free service that provides telephone access to people who are deaf, hard-of-hearing, deaf-blind, and speech-disabled. This service allows text-telephone (TTY) users to communicate with standard telephone users through specially training relay Communications Assistant (CA).

Calls can be made to anywhere in the world, 24 hours a day, 365 days a year with no restrictions on the number, length, or type of calls. All calls are strictly confidential and no records of any conversations are maintained.

Anyone who wishes to use Relay SD simply dials the toll-free relay number to connect with a relay CA. The relay operator will dial the requested number and relay the conversation between the two callers.

A neat feature about Relay SD is the ability to reach ALL services by simply dialing 7-1-1.
