BellSouth Corp says it is interested in an alliance with Chilean cellular telephone operator Telecom which would extend the US firm’s mobile network throughout the country, but said talks with Telecom, controlled by local long-distance carrier Entel-Chile, were not a priority. BellSouth already has a concession covering Santiago and the central Fifth Region. It said it would delay deciding future moves until Chile’s Supreme Court has ruled over an appeal by cellular companies over regulations governing personal telephone concessions which the government plans to award this year.
