The Carretera Austral, a legendary route stretching through Chilean Patagonia, offers unparalleled natural beauty and adventure. As of 2026, while connectivity is improving, it remains highly variable. Expect excellent service in larger towns like Coyhaique, but significant dead zones and limited mobile signal between settlements. This guide provides an essential overview for staying connected, navigating offline, and ensuring safety on this remote journey.

Mobile Providers

Entel

Mobile
Coverage: Generally offers the best, though still intermittent, mobile coverage along the Carretera Austral. Strongest in major towns like Coyhaique, Puerto Aysén, and Cochrane, with some signal in smaller villages. Expect long stretches of no signal, especially south of Coyhaique and between remote communities.
Cost: Prepaid SIM cards typically cost CLP 5,000-10,000, often including some initial credit. Data packages vary widely, from CLP 3,000 for 5GB (7 days) to CLP 15,000 for 30GB (30 days).
Notes: Often the most reliable choice for mobile data and calls in Chile. Purchase upon arrival in larger cities or towns with an official store. Ideal for checking messages and light browsing when available.

Movistar

Mobile
Coverage: Provides decent coverage in larger towns and some populated areas along the route, comparable to Entel in urban centers. However, its reach diminishes rapidly in very remote sections and between towns.
Cost: Prepaid SIMs are similarly priced to Entel, around CLP 5,000-10,000. Data plans are competitive, with options from CLP 2,500 for smaller bundles to CLP 12,000 for larger monthly packages.
Notes: A strong second option if Entel coverage is poor in specific micro-regions. It's advisable to check both Entel and Movistar if possible, or carry SIMs from both if critical.

Claro

Mobile
Coverage: Generally has the most limited coverage among the major carriers in remote Patagonian areas, including much of the Carretera Austral. Primarily found in larger towns; coverage drops off quickly outside of these areas.
Cost: Typically offers slightly more budget-friendly prepaid SIMs (around CLP 4,000-8,000) and data plans (from CLP 2,000).
Notes: Recommended only as a backup option or if your primary provider fails. Not ideal for comprehensive coverage along the entire route due to its limited reach.

Starlink

Satellite
Coverage: Delivers excellent high-speed internet coverage across the entire Carretera Austral route, even in the most isolated valleys, provided you have a clear view of the sky. This service bypasses terrestrial network limitations.
Cost: Requires purchasing Starlink hardware (approx. USD 500-600 in 2026) and a monthly subscription (approx. USD 90-120). Rental options may be available from specialized adventure outfitters in larger cities like Santiago or Puerto Montt.
Notes: The premium solution for guaranteed high-speed internet. Essential for digital nomads, remote workers, or anyone requiring consistent, robust connectivity. Requires a stable power source (e.g., vehicle power inverter).

Garmin inReach / Spot

Satellite
Coverage: Provides global coverage for emergency SOS, two-way text messaging, and basic tracking functions across all parts of the Carretera Austral, regardless of terrain or mobile signal availability.
Cost: Device cost (USD 300-500) plus a monthly or annual subscription plan (USD 15-60/month depending on features).
Notes: Not for internet browsing, but an absolutely crucial safety device for remote travel. Allows you to send custom messages, check-in, and trigger an SOS to a 24/7 monitoring center in emergencies.

SIM Card Guide

For travelers to Carretera Austral, purchasing a local SIM card is highly recommended for when mobile signal is available. You can buy prepaid SIM cards from Entel, Movistar, or Claro at official carrier stores in larger cities like Santiago, Puerto Montt, or Coyhaique. They are also often available at supermarkets, pharmacies, and convenience stores. You will need your passport for registration. Activation is usually immediate. For international travelers, consider an eSIM from a global provider before your trip; many offer regional plans that include Chile, allowing you to have some connectivity upon arrival without needing a physical SIM. Ensure your phone is unlocked and supports eSIM technology.

WiFi Availability

Wi-Fi is generally available in most accommodations (hotels, hostels, cabañas) in towns along the Carretera Austral, though quality and speed can vary significantly. Many cafes and restaurants in larger towns like Coyhaique, Puerto Aysén, and Cochrane also offer Wi-Fi to customers. Dedicated co-working spaces are extremely rare, perhaps only found in Coyhaique. Expect slower speeds than in urban centers and be prepared for occasional outages. Some remote lodges and campsites are beginning to offer Starlink-powered Wi-Fi, providing a faster and more reliable connection for a fee.

Offline Tips

  • 1Download offline maps for the entire Carretera Austral route using apps like Google Maps, Maps.me, or OpenStreetMap before you depart. These are absolutely essential for navigation as mobile signal will be absent for long stretches.
  • 2Utilize dedicated GPS apps (e.g., Gaia GPS, iOverlander for points of interest and campsites) or a standalone GPS device for reliable navigation without relying on mobile data.
  • 3Download all necessary entertainment – movies, music, podcasts, audiobooks – to your devices before heading into remote areas.
  • 4Inform friends or family of your itinerary and expected check-in times. Consider leaving a detailed route plan with your car rental agency.
  • 5Carry multiple portable power banks to keep your phone, tablet, and other devices charged, especially for GPS usage.
  • 6Invest in or rent a satellite communication device (like Garmin inReach or Spot) for emergency communication in areas with no mobile service.
  • 7Download or print all important travel documents, reservations, and contact numbers as digital copies may be inaccessible.

Emergency Communication

Given the remote nature of the Carretera Austral, emergency communication planning is vital. While standard mobile phones will work in towns, they are unreliable in the vast dead zones between them. For true peace of mind and safety, especially if venturing off the main road, consider renting or purchasing a satellite communication device such as a Garmin inReach or Spot. These devices provide global coverage for sending SOS alerts to emergency services, along with two-way text messaging capabilities. Starlink, while providing full internet access, is primarily for connectivity, not a dedicated emergency messaging device unless you have a reliable power source and a method to contact emergency services via internet call or message. Always ensure your vehicle has a first-aid kit, extra fuel, and basic survival gear.
