Cable & Wireless Grenada Ltd. (formerly GRENTEL - Grenada Telecommunications Limited) was formed in January, 1989 when the Grenada Government sold 51% of its shares in the Grenada Telephone Company (GTC), which managed the local networks, to the international carrier, Cable & Wireless West Indies.
Both companies merged to form a joint venture established by the Telecommunications Act of 1989. The Act gave the company exclusive rights to provide telecommunications services in the country.

The Government in December of that same year sold to Cable & Wireless an additional quantity of shares. This increased the Cable & Wireless share holding to its current 70% with the government retaining 30%.

Cable & Wireless West Indies Ltd. undertook a rebranding programme in April 1998, which led to GRENTEL being renamed Cable & Wireless Grenada.

The company's investment of more than EC$110 million over five years has enabled an increase in the number of telephone lines from 7,500 in 1989 to now over 30,776 lines today. Telephone service is available on demand island wide due to the implementation of a number of systems, including a comprehensive computer system that links all aspects of the company's operations. Also in place is a fibre-optic cable ring around Grenada, which has increased the security of the network and improved its ability to withstand man-made or natural disasters.

The company's main office is located on the picturesque Carenage in Grenada's city, St.George's. One branch office is located on the sister island of Carriacou - a small island located about 60 miles off the coast of Grenada; another is located in the South of the Island, Mt. Hartman, Grand Anse. The company also has several remote sites including Mt. St. Catherine and Fort Frederick in Grenada and Mt. Royal in Carriacou.
