Best eSIM for Argentina in 2026: Cheapest and Unlimited Data

I've been to Argentina with an eSIM on my phone, and everything worked great. My job is online and I'm a digital nomad, so after 50+ countries, buying a travel eSIM right before the flight is just part of packing.

My picks

• Best for most trips: Ubigi eSIM for Argentina, 10 GB for 30 days at $23.00, with 5G and hotspot.
• Best unlimited data: eSIMGlobe eSIM for Argentina, unlimited for 7 days at $29.50, with no slowdown listed in its specs.
• Best with Chile, Brazil or Uruguay: Airalo Latin America eSIM, 10 GB for 30 days at $36.00, with Argentina, Chile, Brazil and Uruguay on the same plan.
• Best for light data use: Nomad eSIM for Argentina, 3 GB for 30 days at $9.50, with hotspot.
• Cheapest pay as you go: Roamless eSIM for Argentina, where 1 GB costs $3.45 from credits that never expire.

These five are the providers I trust for Argentina, and you can compare their plans side by side on one page for all five.

Best eSIM for Argentina: 10 GB and 20 GB plans compared

To find the best eSIM for Argentina for your kind of trip, start with 10 GB and 20 GB, both for 30 days. With a month of buses and flights ahead of you, a 30-day plan lasts the whole trip without a second purchase. On the 20 GB plans, 1 GB costs $2.33 to $2.35 at eSIMGlobe, Nomad, Roamless, Saily and Airalo. Ubigi's 25 GB plan brings it down to $1.76.

For a cheap eSIM for Argentina at 10 GB, start with Ubigi's 30-day plan. Every current plan and price is on our Argentina eSIM plans page.

Best unlimited data eSIM for Argentina: eSIMGlobe for a week

For a week, eSIMGlobe is the unlimited data eSIM for Argentina I recommend, because seven days cost $2.63 less than with Roamless.

Roamless, Airalo and Saily give you 3 GB a day at full speed, then 1 Mbps, or "up to 1 Mbps" with Saily. With Roamless, the 3 GB resets "every 24 hours from your first data use". Over a week, that's 21 GB.

What does 1 Mbps still do? In Airalo's words, at that speed "you can still send and receive messages, browse simple web pages, use maps for navigation and make lower-quality video calls".

Ubigi gives you 20 GB at full speed for the whole week, then 2 Mbps. eSIMGlobe lists no speed reduction on its unlimited plans.

For a whole month, Ubigi asks $78.00 for 30 days, against $91.50 at Holafly and $98.99 at Saily. Ubigi's 30-day plan includes 60 GB at full speed, then 2 Mbps.

Proof: Ubigi confirms its 30-day unlimited plan for Argentina includes 60 GB of full speed data, then 2 Mbps

Say you spend a week in Buenos Aires with a work call on video every afternoon. That's the trip eSIMGlobe's 7-day plan suits, because you never stop to count gigabytes. Light users don't need it. If you only open the map now and then between museums and dinners, a 10 GB plan does the job for less.

eSIM cards for Argentina: my five picks reviewed

Ubigi eSIM for Argentina: best for most trips

Pros

• 10 GB for 30 days at $23.00
• Movistar and Personal, both with 5G
• Hotspot allowed on its plans
• Starts on arrival in Argentina

Cons

• No 20 GB plan, 25 GB next
• Data only, calls over WhatsApp

Ubigi eSIM for Argentina is my top pick for most travelers, from a week in Buenos Aires to a month of buses and flights around the country. Skip it if your route goes on to Chile, Brazil or Uruguay, because its Argentina plans work only in Argentina.

The plan I recommend is 10 GB for 30 days at $23.00, because for $2.00 more than 10 GB for 7 days, it lasts the whole month. For a week or less, the 7-day plan at $21.00 is enough. Need more? Ubigi has no 20 GB plan, and the next size is 25 GB for 30 days at $44.00, where 1 GB costs $1.76.

Ubigi uses two networks in Argentina, Movistar and Personal, both with 5G.

Proof: Ubigi confirms its Argentina eSIM connects to the Movistar and Telecom Personal networks, with 5G on both

Hotspot is fine too, in Ubigi's own words "Data sharing allowed".

You can install the eSIM at home the week before you fly, because in Ubigi's words, "your data plan activation starts upon arrival at destination". The plane touches down in Buenos Aires, you switch off airplane mode while it's still taxiing, and an Argentine network shows up at the top of your screen. Only then do your 30 days begin.

When the data runs low, you recharge in the Ubigi app, even without Wi-Fi or data left.

Ubigi plans for Argentina

• 1 GB for 7 days: $6.00
• 3 GB for 15 days: $12.00
• 10 GB for 7 days: $21.00
• 10 GB for 30 days: $23.00
• 25 GB for 30 days: $44.00
• Unlimited (full-speed pool, then 2 Mbps): 7 days $35.00 with 20 GB, 30 days $78.00 with 60 GB

eSIMGlobe eSIM for Argentina: best unlimited data

Pros

• Unlimited for 7 days at $29.50
• No speed reduction listed
• "Hotspot: Yes" on its plans
• Top-ups available

Cons

• 4G only, no 5G
• 30-day unlimited costs more ($126.60)
• No phone number, calls through apps

Seven days of unlimited data cost $29.50 with eSIMGlobe eSIM for Argentina, the plan for a week of heavy use. For a month of unlimited, I don't recommend it: its 30 days cost $126.60, against $78.00 at Ubigi.

The plan I recommend is that 7-day plan, because its specs read "Speed Reduction: NO" and "Hotspot: Yes". Your phone can share this data with your laptop on a day when the hotel Wi-Fi stops working. Check the technical specs of your plan before you buy.

eSIMGlobe's Argentina plans are 4G, not 5G.

On a road trip through the Mendoza wine country, you can keep the map open all day and send the evening's photos home.

There's no new phone number, so calls go only through apps. You can buy it well before the trip, up to 180 days ahead, and you start the eSIM on arrival in Argentina. Top-ups are available too.

eSIMGlobe plans for Argentina

• 1 GB for 7 days: $5.50
• 3 GB for 30 days: $10.30
• 5 GB for 30 days: $14.80
• 10 GB for 30 days: $26.00
• 20 GB for 30 days: $46.60
• Unlimited: 3 days $12.60, 5 days $21.10, 7 days $29.50, 10 days $42.20, 14 days $59.00, 20 days $84.40, 30 days $126.60

Airalo eSIM for Argentina: best with Chile, Brazil or Uruguay

Pros

• One plan for 17 countries
• Argentina, Chile, Brazil and Uruguay included
• No hotspot limit on unlimited plans
• Top-ups when the data runs out

Cons

• Unlimited only up to 10 days
• Argentina-only 10 GB costs more ($30.00)

Routes that cross into Chile, Brazil or Uruguay are where Airalo eSIM for Argentina fits, because its Latin America plan covers all four countries on one eSIM. For Argentina alone, I don't recommend it: Airalo's 10 GB plan costs $30.00, more than Ubigi or eSIMGlobe ask for the same 30 days.

The plan I recommend is the Airalo Latin America eSIM, 10 GB for 30 days at $36.00. One purchase covers the whole route, so when you cross from the Argentine side of Iguazu to the Brazilian side, the same eSIM keeps your map running.

For a few days in Argentina alone, Airalo also sells unlimited data for 3, 5, 7 or 10 days. Its rule reads "Lower speed rate of 1 Mbps after 3 GB usage per day". There's no unlimited plan longer than 10 days, so Airalo doesn't fit a month of unlimited.

Hotspot has no limit on unlimited plans. In Airalo's words, "There is no limit on tethering or the number of devices you connect." If the data runs out early, you buy a top-up, though "It is not possible to extend the validity period".

Airalo plans for Argentina

• 1 GB for 3 days: $5.00
• 3 GB for 7 days: $10.00
• 10 GB for 7 days: $28.00
• 10 GB for 30 days: $30.00
• 20 GB for 30 days: $47.00
• Unlimited (3 GB a day, then 1 Mbps): 3 days $19.50, 5 days $27.50, 7 days $34.50, 10 days $38.50
• Latin America, 17 countries: 10 GB for 30 days $36.00, 20 GB for 30 days $49.00

Nomad eSIM for Argentina: best for light data use

Pros

• 3 GB for 30 days at $9.50
• Hotspot allowed

Cons

• 4G only, no 5G
• No unlimited plan for Argentina
• Use it within 60 days

Maps, messages and ride apps, with Wi-Fi at the hotel for the rest: that's the trip Nomad eSIM for Argentina suits. It's my pick for light data use. Skip it if you need more than a few GB, because Nomad's 10 GB plan costs $28.00, more than Ubigi's.

I recommend Nomad's 3 GB for 30 days because it costs less than the same plan at Roamless ($9.95) or Saily ($9.99). For a few more photos and calls, 5 GB for 30 days costs $16.00.

Nomad's Argentina plans are data only and run on Movistar's 4G network, with no local number. Hotspot is allowed too.

Buy it close to your trip. Nomad asks you to "activate your plan within 60 days of the purchase date", and "After that, it will automatically activate and start the expiry."

If you need more data, you can buy an add-on to your Argentina eSIM, and in Nomad's words, "When your initial plan expires, your add-on activates automatically". Nomad sells no unlimited plan for Argentina, and its largest plan is 20 GB for 30 days.

Nomad plans for Argentina

• 1 GB for 7 days: $5.00
• 3 GB for 30 days: $9.50
• 5 GB for 30 days: $16.00
• 10 GB for 30 days: $28.00
• 20 GB for 30 days: $47.00

Roamless eSIM for Argentina: cheapest pay as you go

Pros

• 1 GB costs $3.45 on credits
• Credits never expire
• Movistar with 5G
• Hotspot with no limit

Cons

• Unlimited only up to 20 days
• No phone number included

Price is the reason to choose Roamless eSIM for Argentina for a stopover or a short visit: 1 GB from credits costs $3.45, while Airalo and Nomad ask $5.00. The credits never expire.

Credits cost less only for small amounts. From 3 GB on, the plan costs less: 3 GB is $9.95 on a plan and $10.35 on credits. Top up once, and you use your credits "for data, calls, and SMS".

You land for two days in Buenos Aires before a flight south, and 1 GB of credits covers the Uber and the map. The rest stays for your next trip.

The plan I recommend is 1 GB on credits for a stay of a few days, because it costs $1.50 less than Roamless's own 1 GB plan at $4.95. For a long weekend with more data, Roamless also sells unlimited for 3 days at $19.08, with 5G. eSIMGlobe's 3 days cost $12.60. That's $6.48 less, but on 4G.

Does an eSIM work in Argentina? Networks, 5G and Patagonia

Yes, an eSIM works in Argentina. The country has three main mobile operators, Claro, Movistar and Personal, and all five of my picks run on Movistar, with Ubigi adding Personal.

Visit Argentina, the country's official tourism site, says all three operators give good coverage in the major cities, while the signal in remote areas can drop, especially with Personal. Claro "typically leads (widest national signal), followed by Movistar, and then Personal". Movistar "performs well in most locations" on the tourist routes, but "In very remote areas or Patagonia, Movistar may have weaker coverage".

Your phone is usually on 4G in Argentina: in the same guide's words, all three carriers offer 4G LTE, "and early-stage 5G in select areas". If you want 5G where it exists, Ubigi and Roamless list it for Argentina, while Nomad and eSIMGlobe are 4G only.

If you want Claro too, eSIMo lists all three networks, with 10 GB for 30 days at $34.90. Check the plan details for hotspot and 5G before you buy.

Coverage can vary around rural roads, mountain routes and journeys away from larger towns, and the tourism guide adds that Personal's "signal is more limited in the southern region (Patagonia)". On a long bus ride across Patagonia between towns, download offline maps of your route before you leave. Then your map works with no signal.

eSIM or an Argentina SIM card?

For most visits an eSIM in Argentina is the easier choice, because it's on your phone before you leave home. An Argentina SIM card makes sense when you need an Argentine number.

Claro, Movistar and Personal all sell prepaid SIM cards, called "chips", to foreigners, and you show your passport or another valid ID. For all three, Visit Argentina puts it this way: "Registration is legally required, but it's a simple process handled by the store staff on the spot". Movistar SIM cards are also sold at kiosks, and you can register them over WhatsApp with your passport details.

A SIM card for tourists still means a stop at a shop or a kiosk after you land. If WhatsApp on your home number is all you need, a SIM card for Argentina isn't worth that extra stop. The full comparison is in eSIM vs SIM card for travel.

Visiting more countries than Argentina? Chile, Brazil and Uruguay

An Argentina plan works only in Argentina. The best eSIM for Argentina and Chile, or for Argentina and Brazil, is a regional plan, and our Latin America eSIM plans page compares them. For 10 GB over 30 days, Airalo's Latin America plan costs $36.00 and Roamless's costs $35.95, $13.00 and $12.95 more than Ubigi's Argentina plan.

Uruguay is the country to check. If you take the ferry from Buenos Aires, Roamless's Latin America plan won't work there, because it leaves Uruguay out. Airalo's plan includes it. On our homepage you pick every country of your route and see the plans that cover all of them.

My verdict: what is the best eSIM for Argentina in 2026?

In Buenos Aires, Mendoza and the other cities, any of my picks works. For Patagonia and long routes between towns, take an eSIM card for Argentina with more than one network. Where one network has a gap, another may still have signal. eSIMo comes first, because it lists Claro, which typically has the widest national signal, along with Movistar and Personal. Ubigi, on Movistar and Personal, is the two-network choice.

For most trips, Ubigi is the best eSIM for Argentina: 10 GB for 30 days costs $23.00, with 5G and hotspot.

My pick for a week of unlimited data is eSIMGlobe at $29.50, with no speed reduction in its specs. For a month of unlimited, Ubigi's $78.00 plan gives you 60 GB at full speed.

Go with Airalo's Latin America plan when Chile, Brazil or Uruguay is on the route. I recommend Nomad for light data use at $9.50 for 3 GB, and Roamless for pay as you go, where 1 GB costs $3.45.
