In the West African country of Ghana, one of the world's poorest places, the busy signal is a reminder of the unfulfilled promise of the Information Age. Making a telephone call here requires persistence. Roughly half don't go through because of system failures, but that's only the start of Ghana's telephone woes. The country has a mere 240,000 phone lines-for a population of 20 million spread across an area the size of Britain. Moreover, telephone bills are inaccurate, overcharges common, and the installation of a new line can cost a business more than $1,000, the rough equivalent of the annual office rent. Lines are frequently stolen, sometimes with the connivance of employees of Ghana Telecom, the national carrier. Phones go dead, and remain unrepaired, for months. Some businesses hire staff for the chief purpose of dialing numbers until calls go through.

The spread of mobile phones has only worsened telephone gridlock. There are more mobile phones in Ghana than wired ones-about 300,000, as of March-but the network is clogged because of a shortage of cell stations. Customers are bedeviled by what operators term "dropped calls." Besides, calls are costly. The price of a one-minute wireless conversation, under the most common plan, is ten times higher than it would be in the United States. "The situation has come to a point of crisis," says Kwesi Nduom, the country's minister for economic planning.
