Internet in Buenos Aires — decent speeds, patchy reliability
Buenos Aires averages around 42 Mbps on fixed broadband, with reliability rated “good” at roughly 82%. That’s enough for daily video calls and most cloud workflows, but not the cleanest experience compared to Western European capitals. Newer Palermo buildings often have fiber (FTTH) reaching 200-500 Mbps; older apartments in San Telmo or Microcentro can be capped at 30-50 Mbps cable or ADSL.
The single biggest risk isn’t speed — it’s short power and fiber outages in summer storms or during Buenos Aires’ occasional grid strain. Always have a mobile backup.

Tips for reliable connectivity
Always have a mobile backup. Buy a prepaid SIM on arrival — Claro, Movistar, or Personal, about USD 5-10/month for 10-20 GB. 4G coverage is excellent citywide; 5G is live in Palermo, Recoleta, and parts of Microcentro. Tether your phone when the fiber drops (and it will, at least once per month).
Check the building before you rent. Ask the landlord or previous tenant which ISPs are installed and run a speed test before paying a deposit. Pre-war buildings in San Telmo may be stuck on 30-50 Mbps ADSL because newer lines haven’t been pulled.
eSIM for the first days. Airalo, Holafly, or Nomad sell Argentina eSIMs starting around USD 10 for a week. Use one for the first 3-5 days while you find a local SIM or get a SUBE card.
UPS for critical calls. If you work remote full-time, consider a small battery backup (UPS) for your router. Grid reliability is the weak point more than internet itself — summer brownouts happen. For workflows you can’t afford to lose, a coworking space with generator backup (WeWork, AreaTres) is the safer default.
VPN on public WiFi. Cafe and coworking WiFi is usually shared-password. Mullvad, Proton VPN, or NordVPN are solid — USD 5-10/month.
Best-connected neighborhoods
Palermo (Soho and Hollywood) — Fiber-heavy, dense coworking coverage, 5G throughout. Default pick for remote workers. Any Palermo cafe gets you 40-80 Mbps.
Recoleta and Barrio Norte — Good fiber coverage, slightly older buildings may lag. See more in the neighborhoods guide.
Villa Crespo — Newer towers often have Telecentro fiber; traditionally slightly cheaper rents than Palermo with similar infrastructure.
Microcentro — Business district, enterprise-grade internet in WeWork and office buildings, but residential stock is older and mixed.
Avoid relying on WiFi in: parts of La Boca, older Belgrano streets far from the main avenidas, and San Telmo pre-war buildings — always tour with a speed test. Compare this to the cost of living trade-offs before committing to a cheaper neighborhood.
