Argentina is concentrating the rollout of 5G in densely populated areas, with the city of Buenos Aires and the province of the same name leading in the number of antennas, in a context of gradual adoption of the new technology.
Two years after the spectrum tender that enabled the development of 5G, there were 1,460 sites deployed, while 4G reached 23,302 sites nationwide, according to the latest figures from the National Communications Agency (Enacom).
Both Claro and Telecom Argentina have stated on various occasions that they are carrying out a rollout of 5G in areas of high population density with the aim of relieving congestion on the 4G network and ensuring the availability of devices capable of connecting to 5G.
It is estimated that less than 20% of Argentina's device base is compatible with 5G networks.
According to Enacom, the autonomous city of Buenos Aires had 509 sites deployed as of September, while the province of Buenos Aires ranked second with 477. Other provinces with high population density, such as Santa Fe and Córdoba, follow with 104 and 103 sites, respectively.
As of September, the regulator recorded 64.89 million mobile lines, an annual growth of 0.31%. 28.3% of accesses were located in the province of Buenos Aires and 19.8% in the city of Buenos Aires. Córdoba and Santa Fe ranked third and fourth, with 8.6% and 7.4% of mobile accesses, respectively.
The mobile sector generated revenues of 5.51 billion (bn) pesos (US$3.7 million) in the third quarter of 2025.
Fixed internet
Fixed internet access reached 12.55 million, 7.33% more than in the same period of the previous year, while household penetration reached 83.6%.
Total fiber reached 5.67 million lines, surpassing cable modem, which closed with 5.33 million. The migration to fiber optics is expected to accelerate in 2026.
Satellite connections grew strongly to 306,096 accesses, driven by Starlink.
Revenues from fixed internet services totaled 2.24bn pesos.
