Fixed-line teledensity in Haiti is the lowest in Latin America, and mobile penetration is the second lowest after Cuba. Political unrest has severely affected investments in a country where most people have no electricity, telephones, or running water. Fixed-line services are provided by state-owned monopoly operator Teleco, which is inefficient and poorly managed. Mobile telephony, instead, is open to competition. Digicel has become the fourth mobile operator, entering the market in 2006. Although only affordable by the wealthy, mobile phones overtook fixed lines in service in 2002. There are now more than twice as many mobile customers as there are fixed-line subscribers, even though mobile penetration is only around 4%. Internet access is also open to competition. WLL and VoIP are being used to supplement the shortage of fixed lines.
