Is there coverage in El Chaltén and on the Fitz Roy trails?

El Chaltén village has data, though it can be slow when busy. Once you're on the Laguna de los Tres or Laguna Torre trails there's essentially no signal, so pre-download maps and plan photo uploads for town.

What about the road between El Calafate and El Chaltén?

It's around three hours of open steppe with almost no coverage. Send any messages and load navigation before you set off. The same national eSIM reconnects automatically when you reach each town.

Good to know in Santa Cruz

Between El Calafate and El Chaltén it's roughly three hours of open steppe with almost no signal; download offline maps and send any messages before you leave town. The trails around Fitz Roy are largely offline too.

Best time to visit Santa Cruz

Patagonian summer, October to April, is the window for glaciers and Fitz Roy; many services and roads close over the harsh, windy winter months.

Traveller streaming and browsing freely on an unlimited-data travel eSIM

Unlimited plans

High-speed data, nothing to count

Priced per day — the longer you stay, the better the daily rate. Ideal for streaming, hotspot and longer trips where you'd rather not watch a data meter. A fair-use policy keeps speeds fast for everyone; see each plan for the detail.

Best for streaming, video calls & hotspot
Great for longer or open-ended trips
One price per day — no GB anxiety

By-the-GB plans

3GB10GB20GB

A set bundle, brilliant value

A fixed data allowance (say 3 GB or 10 GB) valid for your travel days. The best-value pick for lighter trips built around maps, messaging and a bit of browsing. Running low? Top up in a couple of taps — nothing to reinstall.

Santa Cruz eSIM: your local data guide.

Santa Cruz is deep Patagonia: the groaning ice of the Perito Moreno Glacier, the granite spires of Fitz Roy above El Chaltén and the windswept plains toward Río Gallegos. A Santa Cruz eSIM lets you confirm glacier boat times, download trail maps for Los Glaciares and message your lodge from places where towns are hours apart.

One eSIM for Santa Cruz and all of Argentina. It's the national Argentina eSIM — from $5.39/day with unlimited data, working the same in Santa Cruz as it does the moment you leave it.

Across the region

Where you'll lean on data in Santa Cruz.

El Calafate

The glacier gateway town has workable 4G for tours, lodges and the airport transfer.

El Chaltén

Argentina's trekking capital has village data that slows when busy; the trails are essentially offline.

Perito Moreno Glacier

The boardwalks generally hold 4G, but the drive out and the boat trips lose signal.

The practical bit

Getting around Santa Cruz on your eSIM.

Apps you'll want online in Santa Cruz

How long to stay in Santa Cruz

How much data for Santa Cruz

A balanced 3-5 GB is plenty for a glaciers-and-Fitz Roy trip, since the long steppe drives and trails are largely offline; light users may manage on around 2 GB.

Coverage in Santa Cruz

El Calafate and El Chaltén villages have workable 4G, but the vast distances between them, the glacier boat trips and the Fitz Roy trails are largely without signal.
