MCI Relay followed two months later with a Relay Operator system accessible through telnet. MCI Relay and Hamilton Relay both released AOL Instant Messenger relay systems in July of the following year. By 2005, at least four Relay Operator providers (Hamilton, MCI, Sprint, Sorenson, and i711) were providing direct Relay Operator access from the Sidekick using either one of the instant messenger clients or through a free download from the Catalog, and two companies (Lormar Logic and i711) were providing direct TDD access. The software for these is provided at no additional charge in addition to the normal data plan. The free Lormar Logic service also provides the Deaf with direct encrypted calling to the United States Social Security Administration and the Internal Revenue Service. The i711 client provides extra services to the Deaf at an additional fee (such as AAA roadside services, and finding Open Captioned movies, etc.).
