Good to Know
- Buenos Aires has excellent mobile speeds and extensive 4G/5G coverage. Home broadband speeds frequently exceed 200 Mbps, making it reliable for remote work.
- All three major carriers (Personal, Movistar, Claro) support prepaid tourist SIM cards. Physical SIMs are cheap (under 1 USD) and can be purchased at airports, kiosks, and retail stores.
- Movistar offers the fastest broadband (219 Mbps average download) but Personal offers the most consistent mobile speeds (123 Mbps average). Claro has the best coverage in rural Patagonia.
- Tourist SIM cards or e-SIMs cost far less than international roaming (typically $10–$26 for a month of data vs. €10–€15 per MB on roaming). e-SIMs activate instantly before arrival via QR code.
- Public WiFi is available citywide but speeds and reliability vary. Dedicated mobile data is more dependable for continuous nomad work needs.
- Local SIM cards purchased at Buenos Aires airport may cost more than those bought in city stores. e-SIMs avoid queues and language barriers entirely.
- Argentina's mobile networks use GSM standard (same as Europe/Asia), so unlocked phones will work immediately. Check your device is unlocked if coming from a US carrier lock.
