5G Uruguay eSIM | Antel, Movistar & Claro Coverage

A Uruguay eSIM comes with one absolute exception worth knowing before you book: Cabo Polonio has no signal from any carrier — this guide covers that, and the passport rule at official outlets. Uruguay is South America’s quiet 5G overachiever: the state carrier Antel was an early regional adopter, blankets Montevideo and the resort coast, and holds the interior in a way no rival matches. But the country also has one of the region’s starkest coverage exceptions — Cabo Polonio, a village with no electricity grid and no signal from any carrier — and a registration rule that shapes your arrival: every SIM, foreigner included, must be tied to a passport at an official outlet. This guide covers the Antel vs Movistar vs Claro decision, the Punta del Este January congestion effect, and the Carrasco airport kiosk that closes too early for late flights. The sections on coverage and registration below are honest about the Uruguay failures our support desk fields weekly.

Quick answer: The carrier decision in Uruguay matters less than buying before you fly: pick Antel for the widest map or Claro for budget data, and get the profile installed at home. First eSIM? Download and install are both covered in the activation guide.

If your phone’s eSIM status is unverified, the device compatibility checker is the two-minute first step.

The 30-second version: Antel is Uruguay’s coverage leader — the widest 4G map, genuine 5G in Montevideo and Punta del Este, and the only network that holds across Ruta 1 to Colonia and into the interior. Movistar is the strong urban-and-coast alternative that thins inland; Claro is the budget third. Physical SIMs require passport registration at official outlets (the Carrasco airport Antel kiosk is convenient but not 24/7), so the friction-free route is an eSIM bought online before you fly. And if Cabo Polonio is on your itinerary: download offline maps, because no eSIM choice changes that map.

Best carrier for your trip: Antel vs Claro

Your trip	Best carrier	Why
Montevideo city stay	Any of the three	All networks are strong in the capital
Punta del Este and the east coast	Antel or Movistar	Both hold the resort strip; Antel absorbs January crowds better
Ruta 1 and Colonia del Sacramento	Antel	Unbroken 4G along the highway corridor
Interior and northern towns	Antel	The only network with a real rural map
Cabo Polonio and remote Atlantic coast	None — plan offline	No carrier reaches the village; nearest signal ~7 km away
Buquebus ferry from Buenos Aires	Any — with roaming on	The network switches mid-river; your profile has to be ready
Wine country (Canelones, Carmelo)	Antel	Rural winery roads are Antel territory

💡 A multi-network Uruguay eSIM re-selects between Antel, Movistar and Claro automatically — the fix for the west-coast roads where the three footprints trade places.

Uruguay’s eSIM carriers, compared in plain terms

Antel, Movistar and Claro: the Uruguayan comparison

Three networks sit behind every Uruguay eSIM, one of them state-owned, and a rural map that separates them far more sharply than price does.

	Antel	Movistar	Claro
Ownership	State-owned	Telefónica	América Móvil
National reach	The widest by a distance	Strong urban and coast, thins inland	Thinnest of the three
5G	Montevideo, Pocitos, Punta del Este	Growing, selective	Selective
Ruta 1 corridor	Unbroken	Patchy	Patchy
Price	Cheap	Competitive bundles	Cheapest packs
Best for	Country-wide travel, interior, highways	City and resort trips	Budget urban stays

Antel vs Claro: which is better in Uruguay?

Antel — Uruguay’s state-owned carrier — is not just the domestic leader; it is one of Latin America’s strongest mobile networks, an early 5G adopter with genuine coverage in Montevideo, Pocitos and Punta del Este’s main avenues, and the widest rural footprint by a distance. Traveler reports converge on the same story: on Ruta 1 toward Colonia, on the coastal roads east, and in the interior towns, Antel holds while the rivals thin. Ookla’s Speedtest Global Index backs the infrastructure story — fixed medians around 208 Mbps (top-40 globally) in recent editions — and Cable.co.uk’s survey prices local data at roughly USD 0.28 per GB, among the world’s cheapest 20 markets.

The regulator is URSEC, the communications services regulatory unit.

Registration is the one hoop: every SIM in Uruguay is tied to an identity document by law — the clerk scans or photographs your passport at an official outlet. Foreigners can register a limited number of lines per passport, and registration happens only at official shops, not at repair stalls or random resellers. For top-ups afterward, the ubiquitous Abitab and Redpagos kiosks reload credit in cash in under a minute.

Movistar eSIM: the Uruguay urban-coast alternative

Movistar (Telefónica) is the credible number two: very good in Montevideo and along the coastal strip, competitive tourist bundles, growing 5G. Its documented weakness is the interior — traveler accounts of losing signal inland while a companion on Antel keeps streaming are consistent enough to be a pattern. City and resort trip: fine. Country-wide trip: the backup network.

Claro: the budget option in Uruguay

Claro (América Móvil) is the smallest network and prices accordingly — decent urban coverage, cheap packs, noticeably thinner rural reach than either rival. The honest verdict from locals and long-stayers: the few dollars saved are not worth the dead zones unless you never leave the pavement.

Can you buy a Uruguay eSIM from Antel?

Yes for physical SIMs, with paperwork; less clear for carrier eSIMs. Uruguay’s operators sell prepaid lines to foreigners legally and cheaply, but every purchase requires in-person passport registration at an official outlet. That is a fixed cost in time rather than money — the process takes about ten minutes, and the clerk photographs your document.

Where you can buy Uruguay eSIM

	Direct from Antel, Movistar or Claro	Travel eSIM on a Uruguayan network
What you need	Passport registration at an official outlet	A compatible, unlocked phone
When it activates	Store hours, in person	Before you fly, on your own Wi-Fi
Uruguayan number	Yes	No — data-only
Local price	About USD 0.28 per GB — among the world’s cheapest	Fixed upfront price
Top-ups	Abitab, Redpagos and pharmacies, in cash	Not applicable
Best for	Stays past two weeks, or anyone paying locally	Shorter trips and late-night arrivals

The price gap is real but small in absolute terms, because Uruguayan data is so cheap that even an expensive travel eSIM costs a few dollars more for a fortnight. What a local line buys you beyond the price is a Uruguayan number and the ability to top up for cash at any pharmacy — genuinely useful if your stay runs long or you are working locally.

Uruguay coverage gaps: the Cabo Polonio exception and others

Most Uruguay eSIM coverage articles read like the whole country has signal. The reality has a short list of exceptions that matter:

Region	Coverage reality	Best carrier	Watch out for
Montevideo	Dense 4G/5G; excellent everywhere	Any	Congestion downtown at peak
Punta del Este and José Ignacio	Full 4G/5G on the main drag	Antel	January–February saturation drops the peninsula and Playa Brava to 3G
Ruta 1 → Colonia	Unbroken 4G on Antel	Antel	The river road east of Colonia is patchier
Colonia del Sacramento old town	Good in town and at the port	Any	Historic walls weaken indoor signal
Rocha coast (La Paloma, Punta del Diablo)	Town coverage; gaps between	Antel	Movistar thins noticeably here
Cabo Polonio	No signal from any carrier — nearest mast ~7 km at the Valizas turnoff	None	Book your posada before you go; download offline maps in Montevideo
Interior and the north	Antel holds; rivals thin	Antel	Long gaps between towns on minor roads
Rivera and the Brazilian border	Covered, with Brazilian networks bleeding across	Antel	Your phone may lock onto a Brazilian network — check roaming

Why Cabo Polonio has no signal at all

Cabo Polonio is not a coverage gap in the ordinary sense — it is a village with no electricity grid, accessible only by 4x4 or on foot across the dunes, where the nearest confirmed signal is roughly 7 km away at the Valizas turnoff. Three practical consequences:

1. You cannot book or rebook anything from there. Confirm your posada before you travel.

2. Download offline maps in Montevideo, not in Rocha — the coast road has gaps before you even reach the village.

3. Tell someone your plan. This is the correct use case for an offline itinerary and, if you are travelling solo, a check-in arrangement.

What Uruguay coverage maps do not show

• The coast and the capital are covered by everyone. The operator differences only register once you head inland or north.

• January changes the physics. Punta del Este’s population multiplies, and cells built for a small town serve a seasonal city. Speeds fall; coverage does not disappear.

• The Brazilian border is a roaming trap. Around Rivera and Chuy, phones frequently attach to Brazilian networks. If your plan does not include Brazil, switch to manual network selection.

Market context: DataReportal’s Digital 2025: Uruguay counts 7.18 million mobile connections — 212% of the population — against 3.15 million internet users. That saturation figure is the statistical signature of a small, wealthy, thoroughly connected market where the networks are built for residents first and visitors inherit a good deal.

Extending the trip? The same breakdowns exist for our Argentina eSIM guide, Brazil eSIM page and Chile eSIM plans — and note the Buquebus ferry across the Río de la Plata switches you from Argentine to Uruguayan networks mid-crossing, so your profile should be set to roam before you board.

Plan prices compared: online, airport or city store

Route	What it takes	Best for
Travel eSIM online before you fly	Install on Wi-Fi, roaming on at landing	Most visitors — no counter, no registration
Antel kiosk at Carrasco airport (MVD)	Passport registration, ~10 minutes	Daytime arrivals wanting a local number
Antel / Movistar / Claro city stores	Passport registration at an official outlet	Long stays and the biggest local buckets

Route 1 — Buy online and install before you fly

The route that bypasses the Carrasco counter and its closing time.

1. Clear the device question first with the eSIM compatibility tool.

2. The install itself belongs on home Wi-Fi; name the line “Uruguay data” so it is easy to spot.

3. Use it for mobile data and switch data roaming on.

4. Land at Carrasco — or cross on the Buquebus — and the profile attaches automatically.

5. Download offline maps now if Cabo Polonio or the Rocha coast is on your route.

Route 2 — Antel at Carrasco airport

1. Find the Antel counter in arrivals during opening hours.

2. Bring your passport; registration is a legal requirement.

3. Choose a visitor-oriented bundle — staff speak some English.

4. Test data before leaving the counter.

5. Note that the counter is not open around the clock, which is the main caveat.

Route 3 — City store, for longer stays

1. Visit an official Antel, Movistar or Claro outlet — not a repair stall or a reseller.

2. Register with your passport; there is a limit on lines per document.

3. Test data at the counter.

4. Top up later at Abitab, Redpagos or most pharmacies, in cash.

The airport kiosk caveat: the Antel counter in Carrasco arrivals is genuinely convenient — staff speak some English, bundles are visitor-oriented — but it is not open around the clock, and late-night landings find it shuttered. If your flight lands after midnight, either install an eSIM before you fly or plan the store visit for the next morning. Top-ups afterward happen at Abitab, Redpagos and most pharmacies.

Before you buy anything: confirm the phone is unlocked and eSIM-capable (compatibility list), note your EID (*#06#), and install pre-purchased profiles before departure.

Check your phone before a Uruguayan eSIM

Are Android phones OK for Uruguay eSIMs?

Uruguayan networks use standard American bands, widely supported by international handsets. The failures that actually occur:

Device situation	Symptom	What to do
Carrier-locked handset	eSIM will not install or shows no service	Ask your original carrier for the unlock code first
Mainland-China iPhone	No “Add eSIM” option — disabled in that market	Not fixable; buy a physical SIM from an Antel or Claro outlet
Dual-SIM user	eSIM installed, no data	Nominate the eSIM as the data line
Older handset	No EID when you dial *#06#	Buy a physical SIM
Phone locked to a Brazilian carrier	Attaches to Brazilian networks near the border	Use manual network selection, and check roaming terms

The one-minute eSIM readiness test

Run it before you leave home — Carrasco arrivals has no repair kiosk.

• Dial *#06#. If About shows an EID, the phone can hold eSIM profiles.

• On iPhone, Carrier Lock sits under Settings → General → About; “No SIM restrictions” is the target.

• Android: Settings -> Connections -> SIM Manager is the place.

How do I set the APN for my Uruguay eSIM?

Travel eSIM profiles carry their own APN — type nothing. For locally bought lines that fail to pass data:

Carrier	APN	Username	Password
Antel	apn.antel.com.uy (per Antel instructions)	blank	blank
Movistar	internet.movistar.com.uy (per Movistar instructions)	blank	blank
Claro	internet.claro.com.uy (per Claro instructions)	blank	blank

APN values for Antel, Claro and Punta del Este eSIMs

Manual entry is almost never needed on a managed travel eSIM; these are the local-line cases.

• You bought a carrier line rather than a managed travel eSIM

• A profile installed from a manual activation code instead of a QR scan

• An older handset that did not pull carrier settings automatically

• You bought at a reseller and staff did not configure it for you

Uruguay APN settings, carrier by carrier

Settings → Cellular → [the Uruguayan line] → Cellular Data Network on iPhone, or Settings → Network & Internet → Access Point Names on Android. Save, restart, confirm the Antel or Claro line is handling data — official outlets will often pre-configure it at purchase.

How do I install my Uruguay eSIM?

The Uruguay eSIM install is four steps, all done on Wi-Fi before departure: scan the QR, label the line, make it the data line, enable roaming. Our step-by-step activation guide covers the detail.

Uruguay eSIM pre-flight: six things to set on home Wi-Fi

Work through these in advance, especially if you land after the Carrasco counter has shuttered.

#	Check	What “good” looks like
1	Phone not carrier-locked	About page shows “No SIM restrictions” under Carrier Lock
2	Phone supports eSIM	EID shown by *#06#
3	QR code saved	Screenshot on the phone and in the cloud
4	Profile installed before departure	Ready for a midnight arrival or a ferry crossing
5	Data line and roaming set	eSIM is the data line, roaming switched on
6	Cabo Polonio and ferry legs	Offline map saved and roaming on before the Buquebus crossing
7	Offline maps for the Polonio route	Saved in Montevideo, before the coast road

The Uruguay activation process

1. Install before departure if your flight lands late — the Carrasco counter is not a 24-hour safety net.

2. Ferry arrivals from Buenos Aires: enable data roaming on the Uruguay line before boarding, so the profile attaches the moment you cross into Uruguayan waters.

3. Watch the Brazilian border. Around Rivera and Chuy your phone may prefer a Brazilian network; force manual selection if your plan does not include Brazil.

4. Full bars, no data: the data-line setting first, then roaming, then the APN. Our activation troubleshooting guide walks each step.

Troubleshooting a Uruguay eSIM in four steps

A. The eSIM will not install

1. Carrier Lock (Settings -> General -> About) must read “No SIM restrictions” before anything else matters

2. Make sure the QR is unclaimed; most work exactly once

3. Have support resend the profile if it is stuck

B. Installed, but no signal bars

1. Toggle the line off, wait a beat, then on

2. Settings → Cellular → Network Selection → choose Antel manually

3. Reboot, and escalate to a network reset only if the fault stays

C. Signal bars, but no internet

1. Re-key the APN from the table without shortcuts

2. Assign mobile data to the eSIM

3. Line-level roaming needs to be on, not just the handset switch

4. The usage page will show if the allowance is finished

D. Worked all week, dead at the coast or the border

1. Cabo Polonio has no signal at all — check the region table first

2. At the Brazilian border, force manual network selection

3. In January at Punta del Este, congestion rather than coverage is the cause

Why is mobile data so cheap in Uruguay?

Understanding why Uruguay behaves differently helps you buy better:

Feature	Why it matters to you
Antel is state-owned	National coverage is treated as infrastructure rather than a commercial opportunity — which is why the rural map is so much wider than its rivals'
Early 5G adopter	Uruguay had commercial 5G earlier than much of Europe, so “5G” here is a real feature in the cities rather than a marketing label
212% mobile penetration	Networks are built for volume, and per-gigabyte prices are among the world’s lowest
Registration by law	Every line, foreigner included, is tied to an ID document — the one piece of friction in an otherwise easy market
Abitab and Redpagos	The cash top-up network that makes a local line practical for a long stay

Local SIMs in Uruguay vs the travel option

If Uruguay is one stop on a longer route rather than the destination:

1. Decide your countries first, your SIMs second. Argentina, Brazil and Uruguay are three separate network problems.

2. For the river crossing, enable roaming before boarding. The Buquebus hands over mid-river, and you want the profile awake when it does.

3. Watch the Brazilian border. Around Rivera and Chuy, phones prefer the Brazilian network; force manual selection if Brazil is not included in your plan.

4. Keep offline maps for the Rocha coast. The gaps begin well before Cabo Polonio.

5. Plan a cash top-up route if you go local. Abitab and Redpagos are everywhere in towns and nowhere on the coast.

What do travelers ask about Uruguay eSIMs?

Plans and prices: Uruguay eSIMs

Yes — physical SIMs are legal and cheap for foreigners, with one requirement: passport registration at an official outlet, and a limit on how many lines one passport can register. Travel eSIMs bought online skip the counter entirely.

Is ID registration required for SIMs in Uruguay?

Yes — every SIM is tied to an identity document by law, scanned or photographed at the point of sale. The counter step disappears with travel eSIMs bought online; the provider pre-registers.

Which carrier is best in Uruguay?

Antel, on every measure that matters to a traveler: the widest rural map, the strongest 5G, the Ruta 1 corridor, and the interior. Movistar is the urban-coast alternative; Claro is the budget option with the thinnest map.

Will my eSIM work in Cabo Polonio?

No — and neither will anything else. The village has no cell signal from any carrier and no electricity grid; the nearest coverage is around 7 km away. Book accommodation in advance and download offline maps.

Antel vs Claro 5G: which is better in Uruguay?

Yes — Antel’s 5G covers central Montevideo, Pocitos and Punta del Este’s main avenues, with Movistar and Claro expanding selectively. Rural Uruguay is a 4G experience, and it is a good one.

Does my eSIM work on the Buenos Aires ferry?

Once you cross into Uruguayan waters, yes — the profile attaches to a local network mid-crossing if data roaming is enabled. Argentine networks serve the Buenos Aires side; mid-River Plate is the switch zone.

What’s the right GB count for Uruguay?

5–10 GB covers maps, messaging, social and video calls if you use accommodation Wi-Fi for uploads. Local data is among the world’s cheapest — around USD 0.28 per GB — so oversizing costs little.

Can I share my Uruguay eSIM connection?

Yes — hotspot and tethering work on most plans, both local and travel eSIM. Watch the fair-use terms if you plan to run a laptop all day on a resort connection in January.

Cheapest data in Uruguay, compared

Because the market is small, wealthy and state-led: Antel is owned by the government, competition is real, and 212% mobile-connection penetration means operators compete on volume rather than scarcity. It is one of the few countries where a traveler’s per-gigabyte cost genuinely rivals what locals pay.

Is Punta del Este usable in January?

Yes, with a caveat — it is the country’s annual stress test. The peninsula’s population multiplies for the summer season, and cells built for a much smaller town are shared among everyone. Expect lower speeds at peak hours rather than no service.

Do I need a local number for a long stay?

For stays past two weeks, and especially if you are opening a local account or dealing with Uruguayan businesses, yes — buy an Antel line with your passport and top up for cash at Abitab. For a holiday, a data-only eSIM covers everything.

Will my Uruguay eSIM work in Argentina or Brazil?

Not on a Uruguay-only plan. For a Río de la Plata or Southern Cone loop, price a regional plan instead of stacking profiles — our Argentina eSIM guide and Brazil eSIM page cover the two most common onward stops.

Is Antel really that much better than Movistar and Claro?

For a city holiday, no — all three are good in Montevideo and along the resort coast. For anything inland, on Ruta 1, or in the interior towns, yes: Antel holds where the others thin, and that is the trip type where the difference shows.

Can I use a Uruguayan SIM in Argentina?

It will roam, but Uruguay is not in the EU and there is no equivalent free-roaming arrangement across the Río de la Plata. Expect charges, and price a regional plan if your itinerary crosses the river more than once.

How Uruguay data plans break down

For a short trip, a travel eSIM — because local data is so cheap that the gap between it and a travel plan is a few dollars, which is not worth a registration queue. For a month or more, an Antel line topped up in cash is the cheapest connectivity in South America.

Local numbers in Uruguay: do you need one?

Only if you are staying long enough to deal with local services, open a local account, or be reachable by a Uruguayan business. For a holiday, WhatsApp over data covers everything.
