📺 How we use Holafly on the road: https://youtu.be/PygXsK0KsAo

We're official Holafly ambassadors (since May 2022), and Holafly is the only travel-data service we use. We've relied on it firsthand across the Americas — Mexico, Nicaragua, Costa Rica, Panama, and the USA — which is a big part of why it's our pick for a route like this. Pricing verified July 2026.

Why Pan-American overlanders choose Holafly Plans

The route: roughly 19,000 miles from Alaska to Ushuaia, across 14+ countries — North America (Alaska, Canada, USA, Mexico), Central America (Guatemala, Honduras, El Salvador, Nicaragua, Costa Rica, Panama), a shipping stop around the roadless Darién Gap, and South America (Colombia, Ecuador, Peru, Chile, Argentina).

The connectivity problem: the traditional approach means buying and topping up a different SIM in every country — a new provider, a new language barrier, and new plan restrictions at each border, over and over.

The Holafly Plans approach: one eSIM for the whole journey. You cross a border and the plan connects to the local network automatically — no SIM swapping, no negotiating at a shop, the same unlimited data throughout.

What Plans solves on the Pan-American

Remote work that funds the trip. Unlimited data on Plans Unlimited supports video calls from a campsite, uploading content, running an online business, and VPN security — the difference between a working overland trip and a purely offline one.

Border crossings without the SIM hunt. Instead of finding a shop (often closed on weekends), negotiating in Spanish or Portuguese, and hoping you understand the restrictions at every one of 14+ borders, you just keep driving and stay connected. For non-Spanish/Portuguese speakers, that alone can justify the plan.

Safety on remote stretches. Across the Baja desert, Central American mountains, the Peruvian Andes, and Patagonia, data is what keeps you reachable — for the iOverlander community, breakdown coordination, medical navigation, weather and road warnings, and embassy contact.

Why one Plan beats a SIM in every country

Buying a local SIM at each border can look cheaper on paper, but it comes with constant SIM-hunting, language barriers, tourist pricing, and capped data that runs out mid-country — repeated more than a dozen times. One Plan gives you unlimited data, hotspot sharing, no negotiations, and no gap in coverage between borders. For a trip measured in months, the convenience and the always-connected safety margin are the whole point.

Pan-American coverage, honestly

Holafly Plans connects automatically to local networks across all the countries on the route. As with any mobile network, coverage is strongest in cities and along major highways and weaker in remote wilderness — the Baja desert, high Andes passes, deep jungle, and the emptier stretches of Patagonia. That's a limitation of cell towers everywhere, not the eSIM.

From our own travels in Mexico and Central America (Costa Rica, Nicaragua, and Panama among them), connectivity along the main corridors and in towns was reliable for navigation and daily use. For the countries we haven't personally driven, the same pattern holds on Holafly's coverage guidance: solid in populated areas and along the Pan-American corridor, patchier off-grid. Plan for offline maps on the remote sections regardless of provider.

The Darién Gap: there's no road between Panama and Colombia, so vehicles ship by cargo while passengers fly (typically Panama City to Cartagena). Your Plan works in Panama before shipping and in Colombia after, so you can coordinate the logistics over WhatsApp and stay reachable throughout.

Apps Pan-American overlanders rely on

  • Navigation: iOverlander (campsites, warnings, tips — the most important one), an offline-capable map app, Google Maps, and Waze for road conditions
  • Community & safety: iOverlander safety ratings, overlander Facebook and WhatsApp groups for convoy coordination, and Instagram to connect with others on the route
  • Border crossings: translation, a currency converter, a document scanner for permits and insurance, and a VPN for banking security

All of it runs on data — which is why an unlimited plan that never lapses between borders is such a fit.

Real overland scenarios

12-month Alaska → Ushuaia. A full run of the highway with daily navigation, border research, social updates, and a few remote-work days a week. Plans Unlimited Annual — $594.81 for the whole year (about $49.57/month) covers it end to end, unlimited.

6-month USA → Costa Rica. Working remotely to fund the drive — client calls, file uploads, email, and VPN. Plans Unlimited Monthly — $58.41/month, cancel when you arrive.

18-month full round trip, family of four in an RV. Parents working, kids on online schooling, evenings streaming, a travel blog — all sharing one plan via unlimited hotspot. Run the annual plan ($594.81) for year one, then $58.41/month after. Unlimited hotspot keeps the whole family connected on a single subscription.

What travelers say

Across overlanding forums and communities, the same points come up for long Latin America drives: people love not having to buy and configure a new SIM at every border, the unlimited data holds up for remote work and daily navigation along the main corridors, and having one always-on plan (rather than gaps between countries) is repeatedly described as a safety feature, not just a convenience. Non-Spanish speakers especially mention skipping the shop negotiations entirely.

Pan-American FAQ

Does Holafly Plans work in all the Pan-American countries? It covers 160+ destinations, including the USA, Canada, and Mexico; all of Central America from Guatemala through Panama; and Colombia, Ecuador, Peru, Chile, and Argentina — the full highway route.

What about language barriers buying SIMs? You skip them — no SIM shops, no Spanish or Portuguese negotiations, automatic network connection, and 24/7 English support. For many overlanders that's reason enough on its own.

Can I work remotely the whole route? Yes — unlimited data supports video calls, VPN, uploads, and cloud work wherever there's solid coverage, which is most populated areas and main corridors. Keep offline maps for the remote stretches.

What about the Darién Gap? Your Plan works in Panama before shipping and in Colombia after, so you stay connected to coordinate the crossing.

How do I share with family or crew? Plans Unlimited includes unlimited hotspot — connect laptops, tablets, and everyone's devices through your phone.

Do I need a lot of equipment? No — it's an eSIM on your phone, so there's no dish or extra hardware to power, mount, or guard, and it keeps working while you drive.
