Uruguay eSIM Guide 2026
Uruguay is South America's calm, well-organized corner: the relaxed capital Montevideo on the River Plate, the glamorous beach resort of Punta del Este, the colonial charm of Colonia del Sacramento, and the laid-back coastal towns and gaucho estancias of the interior. Uruguay has some of the best mobile infrastructure in South America, with excellent coverage across the country and strong 5G. An eSIM is live before you leave the airport, and coverage is good almost everywhere you go, with only the most rural interior areas thinning out. For the cities, the coast and the main circuit, Uruguay is very well connected. This hub maps it all.
We sell eSIMs, so read every recommendation here as exactly that. Where a local SIM or your home roaming genuinely beats us for your trip, this guide says so plainly.
Uruguay in one screen
Uruguay has excellent 4G coverage across Montevideo, Punta del Este, Colonia and the country, delivered by three networks: Antel (the strong state operator), Claro and Movistar. Uruguay has among the best mobile infrastructure in South America, with strong 5G in the cities and the coast. 4G is the practical standard elsewhere and handles everything a traveler does. The country is small, flat and well-developed, so coverage is good almost everywhere, with only the most rural interior and the deepest countryside thinning out. For the cities, the coast and the main circuit, coverage is very good. This hub maps it all.
Sort your data before you land, not at an airport kiosk and not by leaving your home carrier's international roaming on. Uruguay sits outside most European and Asian roaming bundles, so day-fees are steep. A travel eSIM bought at home and switched on after landing skips the queue and the roaming bill entirely.

Uruguay eSIM FAQ
Does an eSIM work everywhere in Uruguay?
Effectively yes. Uruguay has among the best mobile infrastructure in South America, so an eSIM works across Montevideo, Punta del Este, Colonia, the coast and the main towns with good coverage. The country is small and well-developed, so the gaps are minor, limited to the deepest rural interior and a few deliberately off-grid spots like Cabo Polonio. The eSIM connects to Antel, Claro or Movistar the same way a physical SIM does.
Which network has the best coverage in Uruguay?
Antel, the state operator, is generally considered to have the widest reach and is a strong network nationwide, leading on coverage and 5G. Claro and Movistar are also good, particularly in the cities and coast. For the broadest coverage including the rural interior, an Antel-based or multi-network eSIM is the safest choice, though all three perform well across this well-connected country.
Is there 5G in Uruguay?
Yes, Uruguay has a strong 5G rollout, led by Antel, with good 5G across Montevideo, Punta del Este and the main areas. The country's excellent 4G handles everything a traveler does elsewhere. Uruguay is one of the better-connected countries in South America, so in the cities and coast you will often have fast 5G, with reliable 4G nearly everywhere else.
Can I keep my home phone number with an eSIM in Uruguay?
Yes. A travel eSIM is a separate profile, so your home SIM stays active alongside it. You keep your home number for calls and texts while your data runs through the Uruguay eSIM. Keep home data roaming switched off so you are not billed a daily fee.
How much data is enough for a Uruguay trip?
For a typical week or two covering Montevideo, the coast and the main circuit, around 5 to 10 GB is comfortable for most travelers. Uruguay is easy and well-connected, so you can rely on mobile data freely. The data needs article breaks this down by traveler type.
