eSIM Travel Tips for Buenos Aires
Book a Taxi or Transfer From EZE Airport
Ezeiza International Airport is 45km from the city centre. Uber operates in Buenos Aires but pick-up at EZE can be complicated due to taxi union restrictions. Use Cabify or a pre-booked transfer. Your HelloRoam eSIM keeps the app running from arrivals.
Palermo Is the Best Tourist Base
Palermo Soho, Palermo Hollywood, and the Las Canitas area have strong outdoor 4G. These are Buenos Aires' safest and best-connected tourist areas.
Save Your Location: Buenos Aires Addresses Use Intersections
Buenos Aires addresses are often given as intersections rather than house numbers. Save your hotel address as a GPS pin in Google Maps offline before arriving.
Download Maps Before Day Trips Outside the City
Day trips to Tigre Delta and the Buenos Aires province pampas can have weaker signal on rural roads. Download offline maps before leaving the city.
Know the Emergency Number in Argentina
Argentina's police number is 101 and ambulance is 107. The general emergency number is 911. Save these before using public transport, attending tango shows, or exploring after dark.
Network Coverage in Buenos Aires
Buenos Aires has 4G LTE coverage across all major barrios. The city centre (Microcentro), Puerto Madero waterfront, Palermo, Recoleta, San Telmo, and La Boca all have solid outdoor 4G from multiple operators. Claro Argentina has the widest 4G footprint in the Buenos Aires Metropolitan Area (AMBA). Movistar and Personal provide strong coverage in the central barrios and expand into the wider conurbano.
Ezeiza International Airport (EZE) has 4G in the terminal buildings and parking areas. Jorge Newbery Airport (AEP), the domestic airport in the city itself, also has 4G. The Buenos Aires Subte (metro) has spotty signal in the deeper underground sections. Lines A, B, D, and E lose signal on longer underground stretches, while Lines C and H near the surface have more consistent 4G. Aboveground BRT and bus corridors in the city have full 4G.
The Buenos Aires Premetro tram and suburban rail stations (Mitre, Sarmiento, Roca lines) have 4G at all major stations. Trendy barrios like Palermo Soho, Palermo Hollywood, Villa Crespo, and Chacarita have reliable 4G for navigation and social media. Gran Buenos Aires suburban areas have variable quality, with the main GBA corridors covered and outer pockets having weaker signal.
5G rollout in Buenos Aires began in 2024 but remains limited to select city-centre areas. Most travellers will be on 4G LTE for the duration of a Buenos Aires visit. New Zealand travellers should confirm their handset is unlocked and supports local network bands.

eSIM vs Local SIM in Buenos Aires
For Kiwi travellers, a HelloRoam eSIM is generally cheaper than buying a local SIM on arrival or using an international add-on from a New Zealand carrier.
| Category | HelloRoam Recommended | Argentine local SIM (Claro/Personal/Movistar) | Carrier roaming |
|---|---|---|---|
| Typical cost | From NZ$7.71 total | NZ$8.58–NZ$42.92 total | NZ$8.58–NZ$25.75/day |
| Details | Buy before you leave. Fixed price in NZD. No exchange rate confusion or peso calculations at an airport kiosk. Data is active when you land at Ezeiza. No ID registration or paperwork required. | Tourist SIMs are available at the airport and in city shops but require passport registration. Prices are quoted in Argentine pesos, which fluctuate significantly. Top-up can be confusing for short-stay visitors who do not speak Spanish. Exchange rate complexity adds friction to getting the right plan. | Home carrier roaming in Argentina is expensive. Daily rates of NZD 10 to 15 are common on US plans. A week in Buenos Aires at roaming rates costs NZD 70 to 105 for data alone, often with speed caps after a small daily allowance. |
Prices approximate as of . Actual savings vary.

Buenos Aires Tango Festival (August) is a local highlight. Avoid January–February if possible. Your HelloRoam eSIM keeps you online all year.

Cat
On a trip to Europe, my hotel Wi-Fi was so slow and outside Wi-Fi was unreliable. I couldn’t take it anymore so I got helloroam for a few days. It was tricky to set up correctly because of the primary settings (with my original number). But I reached out to their customer service via WhatsApp. Super responsive and helpful, with specific and clear steps to troubleshoot. Appreciate having 4G roaming instead of being stuck with in and out Wi-Fi during my trip!!
Rated 5 out of 5 by this reviewer
Very good experience! The eSIM was easy to set up and worked great in London. It was much cheaper than it would have been to use my own operator there.
