Phone and Internet in Argentina for Foreigners

Expats · Argentina

Foreigners in Argentina can get a working mobile line in minutes, but only with a valid passport and a declared length of stay: the national telecoms regulator ENACOM requires both. The three big networks, Claro, Movistar and Personal, all sell prepaid tourist packages, and Personal also sells an eSIM online.

The Short Answer: What You Need to Get Online in Argentina

Bring your passport and buy the SIM at a carrier shop or an authorised dealer, not from a street seller. The operator must ask for your passport or travel document and the length of stay you plan.

If you stay longer than you declared, the line stops carrying traffic until you confirm your registration and a new stay period. Calls to customer service and emergency numbers keep working while the line is blocked.

How SIM Registration Works for Foreigners

The rule sits in Article 8 of ENACOM Resolution 263/2023, which replaced the regulations attached to the older Resolution 8507/2016. Foreigners without an Argentine ID must show a valid passport and/or travel document and declare how long they will stay.

When that period ends, the operator must disable the line, except for customer service and emergency services, until you renew your registration. Article 3 of the same resolution requires operators to offer registration in person or remotely, so the exact route depends on the operator.

Foreigners who hold an Argentine DNI follow the same biometric identity validation as citizens. If you only have a passport, expect the operator to handle your documents itself, and ask which route it offers.

The Three Networks Compared

Claro, Movistar and Personal run the main mobile networks. The national tourism board listed the tourist products below in May 2025, so treat the prices as a guide to the price level, not as a current quote. We did not check them against the operators’ current price lists.

On those 2025 figures Claro offered the most data, Movistar the lowest price for a 30-day package and Personal the shortest, cheapest bundles. Compare current prices before you choose.

eSIM: The Fastest Option If Your Phone Supports It

Personal sold an eSIM online with an international credit card, activated immediately by QR code, according to the tourism board in May 2025.

An eSIM only works on a phone that supports it and is not locked to your home carrier. Check both before you fly, because a locked phone cannot take a local line of any kind.

Home Internet: Fast on Paper, Uneven in Practice

Argentina’s fixed internet has improved quickly. ENACOM figures reported by DPL News in April 2026 show 6.2 million fibre-optic accesses, roughly double the 2023 level, and an average national speed of 245.53 Mbps, up 9.2% in a semester.

Satellite internet is growing too, with more than 750,000 accesses reported in April 2026, a sign of demand outside the fibre areas.

An average hides large differences. Ask any landlord which provider serves the building before you sign, because a fast national average does not guarantee fibre at your door.

Public Wi-Fi and Coworking

Buenos Aires runs a free public network, BA WiFi, with more than 1,200 antennas at over 1,000 busy spots. The tourism board says it gives around 5 Mbps per user in 30-minute sessions, which is enough for messages, not for video calls.

For work, the board lists coworking spaces in Buenos Aires, Córdoba, Mendoza, Rosario and Bariloche, with day or week passes it puts at US$2–5. Those prices date from May 2025.

A Short Checklist Before You Go to the Shop

Take your passport and an unlocked phone. Know the date you leave, because you must state your stay length, and add a few days of margin so the line does not stop on the way to the airport.

Ask four questions at the counter: how many days the package lasts, what happens to unused data, whether messaging apps are included, and how to top up. The tourism board says Claro’s tourist chip included unlimited WhatsApp and social media in May 2025, so ask whether that is still the case.

Keep the activation confirmation and the passport details you gave. You will need them if the line is blocked and you have to reconfirm your registration.

The Downsides

Registration of a physical SIM needs a trip to a shop. Prices change often, and the cheapest promotions usually require a new line or a change of operator.

We found no independent coverage tests. If you travel to Patagonia or the Andes, carry offline maps and a second option, such as a Personal eSIM next to a Claro SIM.

What It Means for You

For a short stay, buy a Personal eSIM before you land, and add a physical SIM if you plan to leave the cities. For a stay of several months, register a physical SIM in your own name with the stay length you really need.

Argentina’s monthly inflation was 1.7% in August 2026, and INDEC publishes the September figure on 13 October. At the 9 October EODHD close of 1,516.75 pesos per US$1, plans priced in pesos can rise in dollar terms without notice, so confirm the price on the day.
