In late 2011 when outside operators came into the country, the Costa Rican Electricity Institute had 90% of the mobile market but a year later this dropped to 79%.
The information comes from the Telecommunications Statistical Report prepared by the Superintendency of Telecommunications (Sutel). The report indicates that the fastest growing company in the same period was Claro, which went from having 3% to 9% of the market in twelve months.
Since the formal break up of the monopoly held by the state communications firm, ICE, the number of allocated cell lines has grown from 3.9 to 5.3 million.
Elfinancierocr.com reports that this information was obtained "by an appeal to the Constitutional Court, which forced the Sutel to provide the number of lines that the ICE had up to November 2011, which was considered a strategic issue by the state company and the regulator. "
