Argentina Internet Speed Test - Check Fiber & 5G

Cable Broadband

Eight submarine cables connect Argentina to global networks. The Firmina cable landed in Las Toninas in 2025, running from South Carolina to Argentina with additional landings in Brazil and Uruguay. This Google-backed system provides direct US connectivity.

The SAC-2 cable launched in Q1 2025, connecting Myrtle Beach, South Carolina to Las Toninas. Other cables include Tannat, Unisure, SAm-1, SAC, Malbec, Bicentenario, and the ARSAT cable. These systems provide redundant international connectivity with landing stations concentrated in Buenos Aires province.

Fiber Broadband

Domestic fiber expanded rapidly across urban centers. State-owned ARSAT operates the Federal Fiber Optic Network (Refefo) connecting over 1,200 towns. In 2024, ARSAT signed agreements to light up 4,405 kilometers of unused fiber cables spanning 14 provinces.

Personal (Telecom Argentina) operates the widest national fiber footprint. Movistar's fiber network concentrated in Buenos Aires, Córdoba, Rosario, and other major cities delivers the fastest average speeds. Claro expanded fiber coverage through cable operator acquisitions. Regional ISPs including Metrotel, cooperatives, and municipal networks serve secondary cities.

Mobile Networks

5G networks cover major population centers. Telecom Argentina operated 550 5G sites in early 2025 with plans to reach 750 sites by year end. Movistar and Claro deployed 5G in Buenos Aires, Córdoba, Rosario, Mendoza, and other large cities.

ENACOM opened the 2.3-2.4 GHz band for private 4G and 5G industrial networks. Coverage projections estimate 84% population coverage by 2030, up from 38% in 2025, with most cities achieving full 5G coverage by 2027. 4G LTE networks cover over 95% of the population, providing the primary mobile connectivity for most Argentines.

Urban Areas

Buenos Aires province and metropolitan region hold the strongest internet infrastructure with fiber choices from Personal, Movistar, Claro, Telecentro, IPlan, and regional providers. Fixed broadband speeds in Buenos Aires average 151.9 Mbps download and 92.2 Mbps upload, the nation's fastest.

Personal Fibra delivers 212.0 Mbps average in the capital. Over two-thirds of Buenos Aires households achieve 50+ Mbps speeds. 5G coverage spans the metro area from multiple operators. Residents choose from fiber plans starting at ARS 14,000/month for 100 Mbps to ARS 35,000-40,000/month for 1 Gbps.

Secondary Cities

Córdoba City averages 86.8 Mbps download and 54.3 Mbps upload, making it the second fastest major market. Personal Fibra achieves 171.7 Mbps average. Rosario, Mendoza, Santa Fe, and other provincial capitals enjoy multiple ISP choices with fiber, cable, and 5G options. These central region cities typically see speeds of 70-100 Mbps. Secondary cities have 2-3 ISP options with speeds of 40-80 Mbps.

Rural Areas

Rural provinces face a sharp digital divide. While mobile 4G LTE covers over 95% of the population, typical speeds in rural areas drop to 15-30 Mbps. Northern provinces including Formosa, Chaco, and Misiones, plus southern Patagonia regions show significant gaps.

Many rural residents lack fiber options and depend entirely on mobile broadband or satellite. ARSAT's expansion aims to connect more rural towns with fiber backbone, though last-mile deployment remains economically challenging.

Remote and Underserved

Starlink and other satellite providers entered the market to serve remote estancias and small towns without terrestrial options.

Personal (Telecom Argentina) dominates as the incumbent operator with 4.0 million fixed broadband subscribers representing one-third of the national total. Personal operates the widest fiber footprint across Argentina's provinces. Personal Fibra delivers strong speeds including 212.0 Mbps average in Buenos Aires and 171.7 Mbps in Córdoba.

Personal mobile

Personal mobile holds 33% market share. In March 2025, Telecom Argentina completed regulatory filings to acquire Telefónica Móviles Argentina (Movistar mobile), which would give it 61% mobile share pending final approval.

Movistar (Telefónica) earned recognition for the fastest fiber network in Argentina. nPerf testing showed Movistar averaging 167.4 Mbps download and 127 Mbps upload nationally in Q3 2025. Movistar concentrated fiber deployment in Buenos Aires, Córdoba, Rosario, and major cities rather than pursuing widest coverage.

Movistar mobile held 28% market share before the acquisition by Telecom Argentina. The fixed broadband unit remains separate.

Claro dominates mobile with 40% market share, the largest in Argentina. Claro expanded fixed broadband through cable and fiber, competing primarily in urban markets. Claro's 5G network covers Buenos Aires, Córdoba, and other major cities.

Telecentro

Telecentro operates as the leading independent cable operator with 1.5 million fixed broadband connections, representing 12-13% national market share. Telecentro serves primarily Buenos Aires province and central regions. Plans focus on cable and hybrid fiber-coax rather than pure fiber-to-the-home.

IPlan targets premium customers in Buenos Aires and select cities with symmetrical fiber plans up to 1 Gbps. Regional cooperatives, municipal networks, and smaller ISPs serve specific cities and towns, providing important competition outside major markets.

Affordability

Internet costs a moderate portion of Argentine household income adjusted for purchasing power. The average household earns approximately ARS 500,000-600,000 monthly in 2025. Fiber at ARS 20,000/month for 300 Mbps represents 3-4% of household income. This compares favorably to neighboring countries when adjusted for local purchasing power, though high inflation creates pricing volatility.

Fiber entry starts at ARS 14,000-16,000/month for 100 Mbps plans from major operators. Standard 300 Mbps plans cost ARS 20,000-24,000/month. Gigabit fiber runs ARS 35,000-40,000/month.

Contract and Fees

ENACOM deregulated pricing in April 2024, eliminating caps. Average monthly costs rose from ARS 3,700 to ARS 15,600 by end of 2024 as operators adjusted to market rates and inflation. Installation fees typically run ARS 5,000-10,000 including equipment.

Mobile Data Pricing

Mobile data offers lower entry points. Prepaid plans from Claro, Personal, and Movistar start at ARS 2,000-3,000/month for 3-5 GB. Mid-tier plans at ARS 5,000-8,000/month provide 15-25 GB. Unlimited plans cost ARS 12,000-18,000/month with throttling after 30-50 GB. Prepaid dominates over postpaid due to economic volatility.

Contract and Fees

Regional pricing varies little despite speed differences. Buenos Aires users paying ARS 20,000/month get 150+ Mbps from top providers, while provincial users may see 50-80 Mbps on the same plan due to infrastructure limitations. Always verify actual speeds in your specific address before committing to long-term contracts. Dollar-linked pricing remains rare after currency controls loosened.

5G Rollout

5G deployment accelerated across 2024-2025. Telecom Argentina operated 550 sites in early 2025 with targets to reach 750 by year end. Movistar and Claro deployed networks in Buenos Aires, Córdoba, Rosario, Mendoza, and other major cities. ENACOM opened the 2.3-2.4 GHz band for private industrial networks.

Coverage projections estimate 84% population coverage by 2030, up from 38% in 2025. Most cities will achieve full 5G by 2027. Adoption grows through fixed wireless home internet rather than smartphones initially, as 5G handsets remain expensive for most Argentines.

Fiber Deployment

Fiber-to-the-home expanded through competitive deployment by Personal, Movistar, Claro, and regional operators. Buenos Aires province, Córdoba, Rosario, and major cities now have fiber passing most urban homes.

ARSAT's federal backbone connects over 1,200 towns with plans to light up 4,405 kilometers of additional fiber across 14 provinces. Fixed broadband subscriptions concentrate in urban centers.

Argentina operates as Latin America's second-largest technology hub after Brazil. Buenos Aires hosts 400,000+ tech workers across startups, fintech, software development, and business process outsourcing. Companies including MercadoLibre, Globant, Auth0, and hundreds of startups demand reliable connectivity. This tech sector drives demand for symmetric gigabit fiber and enterprise-grade SLAs.

Mobile-first internet use dominates consumer behavior. Smartphone penetration exceeds 80%. E-commerce, digital payments, social media, and content consumption run primarily through mobile devices.

The government's Digital Argentina initiative prioritizes closing urban-rural connectivity gaps and promoting digital skills. ENACOM's deregulation aims to stimulate private investment in infrastructure expansion.
