Will it work at the Quilmes ruins?

The Ruinas de Quilmes sit in the remote Calchaquí Valley near Amaicha del Valle, where coverage is limited. Sort your tour details and maps in Tafí or Cafayate before heading out to the site.

Is this the same eSIM I'd use in Salta or Cafayate?

Yes. It's Argentina's single national plan, so it keeps working as you continue north into Salta or up the Calchaquí Valley toward Cafayate. No new SIM is needed at the border.

Good to know in Tucumán

The climb from the city up to Tafí del Valle winds through cloud forest where signal comes and goes on the switchbacks; download the route and any tour details before you leave San Miguel.

Best time to visit Tucumán

Spring and autumn are most comfortable; summer rains turn Tafí del Valle lush and green, while winter stays dry and clear but cooler in the sierras.

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.

Across the region

Where you'll lean on data in Tucumán.

San Miguel de Tucumán

The lively capital has strong 4G and 5G for its plazas, museums and empanada spots.

The misty mountain valley town holds town-centre data, fading on the winding approach road.

Ruinas de Quilmes

The ancient hillside ruins sit in a remote valley with limited, unreliable coverage.

Amaicha del Valle

This Calchaquí village has patchy data, so sort your maps and tours before arriving.
