The Strait of Magellan, a gateway to Antarctica and a region of stunning natural beauty, is also one of the world's more remote areas. While urban centers like Punta Arenas and Puerto Natales offer decent internet, venture further afield, and connectivity quickly diminishes. This guide prepares you for staying connected, or happily disconnected, as you explore this historic waterway in 2026.

Mobile Providers

Entel

Mobile
Coverage: Best overall coverage in populated areas, especially Punta Arenas and Puerto Natales. Spotty elsewhere.
Cost: Moderate to high, depending on data plan. Roughly $10-30 USD for a tourist SIM with good data for 1-2 weeks.
Notes: Reliable in cities, but expect no service in vast stretches of road and wilderness. Good for calls and basic internet in towns.

Movistar

Mobile
Coverage: Good coverage in cities and along main routes.
Cost: Moderate to high, similar to Entel. Roughly $10-30 USD for a tourist SIM.
Notes: Competes well with Entel in urban areas. Performance drops significantly in remote parts of the Strait.

Claro

Mobile
Coverage: Decent coverage in major towns, less extensive than Entel or Movistar in very remote areas.
Cost: Moderate, often slightly cheaper than Entel/Movistar. $8-25 USD for a tourist SIM.
Notes: A viable option in cities; consider for supplementary coverage or if offers are better.

Starlink

Satellite
Coverage: Excellent (where line of sight is clear)
Cost: High upfront cost for hardware ($500-600 USD) plus monthly subscription ($100-120 USD).
Notes: Ideal for truly off-grid connectivity, especially for prolonged stays in remote areas or larger groups. Requires a clear view of the sky.

SIM Card Guide

For international travelers, purchasing a local SIM card is highly recommended. In Chile, you can find official stores for Entel, Movistar, and Claro in larger cities like Punta Arenas. Supermarkets (like Lider, Jumbo) and convenience stores also sell prepaid SIMs, though activation might require an ID/passport and be easier at an official store. Expect to pay around $5-10 USD for the SIM card itself, plus your chosen data package (e.g., $10-25 USD for 5GB-20GB valid for 15-30 days). eSIMs are becoming increasingly popular for international travelers, offering convenience without needing a physical SIM. Check providers like Airalo, Nomad, or Holafly for Chile-specific eSIM plans before you travel. Activation is usually digital and instant.

WiFi Availability

WiFi is readily available in hotels, guesthouses, and many restaurants and cafes in cities like Punta Arenas, Puerto Natales, and Porvenir. Speeds can vary, but are generally sufficient for basic browsing, email, and social media. Free public WiFi hotspots are rare. Outside these urban centers, especially along the more remote stretches of the Strait or on excursions to Tierra del Fuego, WiFi becomes very scarce or non-existent. Always confirm WiFi availability with your accommodation in advance, especially in smaller towns.

Offline Tips

  • 1Download comprehensive offline maps (Google Maps, Maps.me, OpenStreetMap) for the entire region before departure.
  • 2Save essential documents, booking confirmations, and travel itineraries to your device or cloud storage for offline access.
  • 3Download entertainment like music, podcasts, and e-books to keep you company during long drives and in areas without signal.
  • 4Inform family or friends of your itinerary, including expected routes and overnight stops, before entering areas with limited connectivity.
  • 5Carry a physical map as a backup for navigation, especially on remote roads where electronic devices might fail or run out of battery.
  • 6Use a portable power bank to keep your devices charged, as charging opportunities can be limited on the road.

Emergency Communication

Given the vast and often unpopulated expanses around the Strait of Magellan, relying solely on mobile phones for emergency communication is risky. In areas with no mobile signal, satellite communication devices like Garmin inReach or Spot are invaluable. These devices allow you to send SOS messages to emergency services, send texts, and share your location via satellite. For immediate emergencies, call 131 for ambulances, 132 for firefighters, and 133 for police in Chile. Always have these numbers readily available. Ensure your travel insurance covers emergency evacuation and medical assistance in remote regions.
