Mobile telephony was introduced in Mexico in 1989 when Iusacell arrived on the scene.

Over 15 years, Mexico’s mobile industry has matured, absorbing new technologies, and new payment plans as it broadened its customer base. Falling ARPUs have led to consolidation of the sector, and steady increases in network capacity utilization.
