Telefônica Celular, which services more than 23 percent of the Brazilian market, will initially offer CDMA2000 1X services in Rio de Janeiro where the operator currently has market share of more than 63 percent. Telefônica will also offer its 1X services to 20 areas in the southern region of the city, as well as the downtown area and international and domestic airports.
