Argentina: from Buenos Aires to Patagonia's glaciers

First time writing for the Carnet, so let me introduce myself with a confession: I've been quietly in love with Latin America for years, and Argentina is the one that finally got me on the plane. Tango, asado, football arguments that turn into friendships — I came for all of it, and I stayed because the country kept handing me reasons. This is the trip I'd been promising myself, and it splits cleanly in two: Buenos Aires first, then the long fall south into Patagonia.

Let's be honest about scale before anything else, because Argentina humbles you on a map. It's a continent pretending to be a country. Between the capital and the bottom of the world there are thousands of kilometres, and you do not drive them on a whim — you fly. I learned to think of internal flights the way I think of long bus rides at home: a normal part of the plan, booked early, not a luxury.

Buenos Aires, loud and tender

I started in the capital, and Buenos Aires welcomed me the way a big city does when it's sure of itself — no fuss, just rhythm. My days fell into a shape: a café and a medialuna in the morning, walking until my feet complained, a parrilla at night where the grill does most of the talking. The asado here isn't a meal, it's a belief system, and I converted on day one.

I wandered Recoleta with its grand façades and its famous cemetery, a city of marble avenues for the dead; San Telmo on a Sunday, all antiques and street tango; the painted tin houses of La Boca. And the tango itself — not the polished show kind, but a neighbourhood milonga where couples who'd clearly been dancing for fifty years moved like they shared one spine. I didn't dance. I watched, with a glass of Malbec, and that was plenty.

Connection-wise, the capital is easy. In Buenos Aires my eSIM behaved like it would in any major city — solid signal, maps loading instantly, video calls home with no drama. I used it to book restaurant tables, to ride-hail across the city at night, and to send my brother a shaky live video of a street tango couple because some things you simply cannot describe over text.

South, into Patagonia

Then came the part I'd dreamed about: a flight south, and suddenly the country empties out into wind, sky and stone. I based myself first in El Chaltén, the little trekking village under the Fitz Roy massif, and I want to be straight with you here — this is where the signal thins out. In town there's coverage, enough to message and check the weather, but the moment you walk into the mountains you're off the grid, and that's not a flaw, it's the whole point.

I hiked toward the Fitz Roy on a day the famous granite towers actually showed themselves — they're shy, often hidden in cloud — and stood at the lagoon below them feeling very small and very happy. My phone was in airplane mode by then, photos only. The day before, in town, I'd downloaded my offline maps and screenshotted the trail notes, because counting on a live connection on the mountain would have been wishful thinking.

From there to El Calafate, the base for the Perito Moreno glacier — and that glacier is one of the few places on earth that lives up to every photo you've ever seen of it. A wall of cracked blue ice, groaning and occasionally calving great slabs into the water with a sound like distant thunder. I stood on the walkways for hours. Out at the glacier itself, don't expect bars; back in El Calafate, my eSIM picked the network up again and I dumped a hundred photos into the family chat in one go.

What Argentina taught me

What I take home is a rhythm: a noisy, generous city where you're always connected, and a vast south where being unreachable for a few hours is part of the gift. The trick is to plan for both — to arrive in Patagonia with your maps already downloaded and your expectations of signal honestly low, so that when the connection comes back in town, it feels like a bonus rather than a need.

📶 Romain's tip

Sort your eSIM before you land, so Buenos Aires works from the airport — you'll want maps and a ride straight away. In the capital, expect city-grade coverage; in Patagonia, expect good signal in El Chaltén and El Calafate but none on the trails or out at the glacier, so download offline maps and trail notes while you've still got bars. Check your phone's compatibility in 30 seconds here and find your Argentina plan on the destinations page. (Heading to Europe instead? There's a ready-made regional option on the EU/EEA page.)
