eSIM for Patagonia

Patagonia: what to know before you go

Argentina and Chile

Plans are sold per country, so crossing over means one for each. El Calafate, El Chaltén, Bariloche and Ushuaia are on the Argentine side, while Torres del Paine and Punta Arenas are in Chile.

Getting there

You can fly to El Calafate, Ushuaia, Bariloche and Punta Arenas. Beyond that it is mostly long bus rides or a hire car.

Little signal

The towns are covered, the long roads linking them often are not. Keep maps offline and top up fuel whenever you can.

The parks

Long sections of trail in Los Glaciares and Torres del Paine have no signal. Reserve entry and campsites online in advance, and keep the confirmations saved offline.

How much data you need

About 3 to 4 GB is typical for a week of maps, bookings and photos.

Questions about Patagonia

Will I need separate plans for Argentina and Chile?

If you cross the border, yes. Each plan covers one country, so install both and switch over as you cross.

What is the cheapest Patagonia eSIM plan?

Patagonia uses the Argentina plans, because an eSIM belongs to a country and not to a city. $3.99 gets you 1 GB for 7 days. Data sizes range from 1 GB to 20 GB across 9 plans, and there are unlimited day passes too.

Which mobile networks does the Patagonia eSIM connect to?

You get Claro and Movistar. The operators are listed on every plan, so you can check before you buy.

Is there an unlimited data plan for Argentina?

Yes, the day passes. Each day starts with a full speed allowance, and after it you stay online at a reduced speed of 512 Kbps.

Will my phone number still work?

Yes. Every plan is data only, so your regular line stays active for calls and texts, and WhatsApp carries on as usual.

Should I buy a local SIM card in Patagonia?

There is no need. An eSIM is a digital SIM card that you install from a QR code before the trip, so you skip the airport kiosk and never open the SIM tray.

How does it compare with roaming in Patagonia?

The eSIM is prepaid, so you know the full cost before you go and no charges appear later. Roaming is billed afterwards by your own carrier at its own rates, usually per day or per megabyte. Leave data roaming off on your regular line so it cannot bill you.

When is the best time to install the eSIM?

At home, on Wi-Fi, before you leave. Once you arrive, pick the Fizztrip line for mobile data and switch data roaming on for that line.

When does the plan start counting days?

At the first connection at your destination. Buying the eSIM or installing it does not start the clock, so a 30 day plan runs for 30 days from the moment it first joins a network there.

Can I buy the eSIM weeks before my trip?

Yes. Validity only starts at the first connection at your destination, so buying or installing early does not use up any days. Install it before the "Install by" date on your order.

Is there a deadline to install the eSIM?

Yes. Your order and the site show an "Install by" date, and an eSIM that is still not installed after that date expires. Buying early is fine: just install it on Wi-Fi before then.

What happens when my data runs out?

The connection pauses and nothing extra is charged, since every plan is prepaid. Top up from the eSIM page and you are back online on the same eSIM, with nothing to reinstall. On a day pass you get a full speed allowance each day. Once it is used, you stay connected at a lower speed (512 Kbps) until the next day begins.

Can I add data later?

Yes, straight from the eSIM page. The extra data goes onto the eSIM you already have, so there is nothing new to install.

Can I share data with a hotspot?

Yes. Hotspot traffic uses the same plan data and Fizztrip adds no fee for it. Keep in mind that a laptop burns through data much faster than a phone, so for remote work a day pass or a larger plan is the safer pick.
