Uruguay is one of the few countries in South America where the local prepaid card is a genuinely better buy than a travel eSIM, provided you are here long enough to go and get one. Antel, the state operator, sells tourist data packs measured in tens of gigabytes for a few hundred to a thousand pesos, which at roughly 40 pesos to the dollar puts local volume at a fraction of what any travel brand charges. That is the whole argument for the physical card, and it is a strong one on a three-week stay. Against it sit three frictions that nobody mentions in the brochure: you need your passport, you need to be somewhere the operator has a staffed shop, and Uruguayan retail keeps Uruguayan hours, which in the case of the airport desk means weekdays only. Work out which side of that trade you fall on before you land rather than at the baggage carousel.

Antel, Movistar and Claro: Who Sells What
Uruguay's mobile market has exactly three players and they behave very differently at the retail counter. Antel is the state-owned incumbent, the biggest of the three, and the one with the deepest presence outside the capital. Its shops are everywhere, including small interior towns where the private operators have a reseller at best, and it is the only operator with a dedicated point inside Carrasco airport. Movistar, owned by Telefonica, and Claro, part of America Movil, entered when the mobile market opened to competition in 2004 and both concentrate their retail on Montevideo, Punta del Este and the larger provincial cities.
For a visitor, the choice is mostly settled by where you are standing when you decide to buy. In Montevideo all three are trivially available: the shopping centres on Avenida 18 de Julio and in Punta Carretas carry all of them, and there are Antel and Movistar branches within a short walk of most of the tourist centre. Once you leave the coastal strip, Antel is the safe default, both because its shops persist and because its network does.
Buy the brand that matches where you are going
If your Uruguay is Montevideo, Colonia and Punta del Este, any of the three will serve you well and price is the only thing worth comparing. If your Uruguay involves Ruta 5 north, the thermal springs near Salto, the estancia country around Tacuarembo or the unpaved run out to Cabo Polonio, buy Antel and stop thinking about it. Coverage differences between the three are barely visible in the south and quite visible in the north.
All three sell 5G, all three have spectrum in the 3.5 GHz band from the 2023 auction, and in practice you will see 5G in central Montevideo and around the Punta peninsula and 4G everywhere else. None of that should influence which card you buy.
What a Tourist Pack Actually Costs in Pesos
Here is the arithmetic that makes this page worth reading. The Uruguayan peso has traded around 40 to the US dollar through 2026, which makes conversion mercifully easy: knock a zero off and divide by four. Against that rate, the data packs aimed at visitors look like this.
| Operator | Pack | Price (UYU) | Approx USD | Rough per GB |
|---|---|---|---|---|
| Antel | 1 GB, one day | 150 | $3.75 | $3.75 |
| Antel | 40 GB, seven days | 1,000 | $25 | $0.63 |
| Movistar | 3 GB, seven days | 235 | $5.90 | $1.95 |
| Antel | Bare starter SIM, no data | 65 | $1.65 | n/a |
Two things jump out. The first is that the large Antel weekly pack is the cheapest data in this comparison by an order of magnitude, at somewhere around 60 US cents a gigabyte. Nothing sold to travellers comes close. The second is that the small one-day pack is terrible value and exists for locals topping up, not for you: at 3.75 dollars for a single gigabyte over a single day, an eSIM beats it comfortably.
A caveat on sourcing, because you should know how firm these numbers are. Antel does not publish a tidy English-language tourist tariff, and the figures above come from retail and travel guides current in 2026 rather than from an official price sheet. Treat them as the right order of magnitude rather than to the peso, and expect the exact pack names and allowances to shift between visits. What has not shifted in years is the shape of the conclusion: local volume is cheap, tourist convenience is not.
The Passport, and What Nobody Checks
Every one of the three operators will ask for your passport when it activates a prepaid line for you. Staff enter your details at the point of sale and the line becomes associated with your identity document. This is normal practice across all three networks, and a photograph of the passport on your phone is generally not accepted where the original is expected, so carry the book itself on the shopping trip.
Worth being precise about what this is and is not. Uruguay does not appear on the standard international lists of countries with a hard statutory prepaid registration mandate, which is a slightly different thing from operators asking for identification as a matter of commercial policy and anti-fraud practice. The practical effect for you is identical either way: no passport, no line. But it means the requirement is a shop-floor rule rather than a border-control one, and there is no separate registration step you have to complete later, no SMS code from a ministry, and no IMEI declaration of the sort several other countries in this region impose.
What to have with you at the counter
- Your actual passport, not a copy or a photo of one
- An unlocked handset, or an eSIM-capable one if you want the profile rather than the plastic
- Pesos or a card. Both are accepted; Uruguay is comfortably card-friendly and contactless is normal
- A rough idea of the pack you want, because staff will otherwise sell you a monthly local plan
- Patience for the activation, which typically completes in well under half an hour
None of the above applies to a travel eSIM. You buy it in an app with a card, nobody sees your passport, and the profile is issued outside Uruguay entirely. That is a real convenience difference rather than a marketing one, and on a short trip it is most of what you are paying for.
Where to Buy One, and When the Doors Are Open
The airport is the obvious first thought and the least reliable option. Antel keeps a point in the arrivals hall at Carrasco, and according to the airport's own service directory it operates Monday to Friday from 07:00 to 19:00 with no weekend hours listed. Given how much of the long-haul traffic into Montevideo lands in the evening or at weekends, a significant share of arriving passengers will find it closed. Secondary travel guides sometimes claim daily hours running to 22:00; the airport's own listing does not support that, and it is not the sort of thing to gamble a connected arrival on.
In Montevideo itself, the options are plentiful. Antel's own retail network runs to dozens of branches across the country, with several in central Montevideo and the shopping centres. Movistar and Claro both have branches along the main commercial streets and in Punta Carretas and Montevideo Shopping. Standard Uruguayan retail hours apply, roughly 09:00 or 10:00 until 18:00 or 19:00 on weekdays, with shorter Saturdays and very little open on Sunday outside the malls.
Topping up afterwards
Recharging is the easy part and it is where Uruguay quietly excels. Abitab and Redpagos are payment-agent networks with branches and franchised counters in supermarkets, pharmacies and corner shops nationwide, and both handle mobile top-ups for all three operators in cash. You give a counter clerk the number and the amount and it lands on the line within moments. Each operator also has its own app and web recharge, though a foreign card is occasionally refused by local payment gateways, which is exactly when the Abitab counter down the road saves the day.
The convenience-store trap
Plenty of kiosks and small shops advertise recharges, and those will work fine for adding credit to a line you already have. Very few of them can sell and activate a new prepaid line, because that requires the identity registration step. If you need a new SIM rather than a top-up, go to an operator-branded shop rather than the nearest place with a sticker in the window.
Can You Get a Local eSIM Instead of Plastic?
This question comes up constantly and the answer online is a mess, so here is what can actually be established. Antel does issue eSIM profiles: its own online store lists an eSIM as a product at 65 pesos, about a dollar and a half, described as a chip built into the handset that you activate by scanning a QR code, with an instruction page covering both iOS and Android and a device compatibility checker alongside it. So the technology is live and has been for some years.
What is much harder to pin down is whether a walk-in visitor on a prepaid line can get one. Several travel and comparison sites assert flatly that Antel restricts eSIM to contract and postpaid customers and that prepaid remains plastic only. Antel's own product listing states no such restriction anywhere on the page. Those two things cannot both be confidently true, and we could not resolve them from outside the country. Assume you may be told no at the counter, and do not build a travel plan around getting a local Antel eSIM on arrival.
Reasons the local card still wins
Reasons to skip it
Drawing the Line Between Card and eSIM
The break-even here is unusually clean, because the two products are priced for different customers rather than competing head to head. Under a week, buy the eSIM. Nomad's Uruguay packages start at 6 dollars for a gigabyte over seven days and 19 dollars for five gigabytes over a month, which is more than most people burn on a short trip and costs less than the taxi to an Antel shop plus the hour it takes. You land connected, you never queue, and your passport stays in the safe.
Beyond about ten days, or on any trip where you will be tethering a laptop, the local card starts to make the eSIM look silly. A thousand pesos for forty gigabytes is not a marginal saving, it is a different order of pricing, and if you are working from Montevideo for a month there is no honest argument for paying travel rates instead.
The combination most people should actually run
Buy a small eSIM before you fly so you are online at Carrasco regardless of what day you land, then decide in your first few days whether the trip is heavy enough to justify a local card. That way the weekend-arrival problem disappears, you have working maps and messaging from the aircraft door, and you keep the option of walking into an Antel shop on Monday morning if the data burn turns out higher than expected. Running both is normal on a dual-SIM handset and costs you nothing beyond the small eSIM you were going to want anyway.
Three things that catch visitors out
- Sunday is quiet in Uruguay. Operator shops largely close, and the airport Antel point does not open at weekends at all
- A Uruguay SIM or eSIM is useless the moment you step off the ferry in Buenos Aires. Argentina is a separate country and a separate plan
- January on the Maldonado coast is congested rather than uncovered. A local card gets a slightly better place in the queue than a roaming eSIM, which is one more small point in its favour if you are there in high summer
Frequently Asked Questions
Is a local Uruguayan card really cheaper than buying an eSIM at home?
On volume, yes, and by a wide margin. Antel's larger tourist pack is quoted at around 1,000 pesos for 40 GB over a week, which is roughly 25 dollars and works out near 60 cents a gigabyte. The cheapest travel eSIM for Uruguay charges 19 dollars for 5 GB. If you plan to use serious amounts of data, particularly tethering a laptop, the local card is not a close call. If your week involves maps, messaging and the occasional video call, you will not get near 40 GB and the price advantage is theoretical, at which point the eSIM's convenience wins the argument instead.
What happens if I land at Carrasco on a Saturday night?
You walk past a closed Antel counter. The airport's own service directory gives the Antel point in the arrivals hall as Monday to Friday, 07:00 to 19:00, with no weekend hours listed at all. Currency exchange, luggage storage and taxis operate far longer, but the mobile counter does not. Your options that evening are the airport WiFi, hotel WiFi once you reach town, or an eSIM you installed before you flew. For a lot of visitors arriving on the evening long-haul banks, this single scheduling fact is the entire case for buying a travel eSIM in Uruguay.
Can I top up a Uruguayan SIM without a local bank card?
Easily, and this is one of the things Uruguay does better than most of the region. Abitab and Redpagos are nationwide payment-agent networks with counters inside supermarkets, pharmacies and corner shops, and both take cash top-ups for all three operators. You hand over the number and the amount and the credit lands almost immediately. The operators' own apps and websites also work, but a foreign-issued card is sometimes declined by local gateways, so knowing the Abitab option exists saves a frustrating half hour.
Does buying a Movistar or Claro card get me worse coverage than Antel?
In Montevideo, Colonia, Piriapolis and the Maldonado resorts, no. All three networks are well built out across the populated south and you would struggle to tell them apart on a normal itinerary. The gap opens north and east: Antel carries the densest rural footprint and holds a usable signal longest on the interior routes and on the rougher stretches of the Rocha coast. If your trip stays on the coastal strip, buy on price. If it heads inland or out to the dunes, buy Antel.
Will the shop hand me an eSIM if I ask for one instead of a plastic SIM?
Possibly, but do not count on it. Antel plainly issues eSIM profiles, listing one in its online store at 65 pesos with QR activation and a device compatibility checker. What is disputed is whether a prepaid line, which is what a visitor gets, can be delivered as an eSIM or only on plastic. Several travel sites say postpaid and contract customers only; Antel's own product page states no restriction. We could not settle it from outside Uruguay, so plan for plastic and treat an eSIM offer at the counter as a pleasant surprise.
