The Mexican telecom industry is developing rapidly and has enormous growth potential, making it one of the most interesting telecom markets in the world. There have, however, been complaints that, despite liberalisation, basic telephony is still almost a monopoly, with Teléfonos de Mexico (Telmex) holding around 94% of all lines in service. Telmex’s sister company América Móvil dominates the mobile sector through its unit Telcel, which has around 80% of the market. Overall teledensity stands at 18%, which is about average for Latin America, but there are huge disparities between urban and rural areas, ranging from 41% teledensity in the Federal District, to 5% in the poor, mainly Indian state of Chiapas. VoIP has gained huge popularity, especially with small and medium sized businesses. Several companies offer VoIP services, although providers have the same licensing requirements as other voice carriers, and many have been shut down for operating illegally. Broadband, especially ADSL, is one of the fastest growing telecom markets in Mexico. The shift from dial-up to broadband became apparent in 2005, when dial-up accounts started to decrease, while broadband soared by around 122%.
