The 60-second verdict
Flysimio sells 5 GB for 30 days in Uruguay at $27.50 on Claro. Airalo's cheapest 30-day Uruguay plan is $87.00, because they sell the country as unlimited-only. For a week in Montevideo and Punta del Este, our 1 GB / 7-day plan at $5.62 or 3 GB / 30 days at $17.38 is usually all you need.
Uruguay has genuinely excellent infrastructure for its size — Antel, the state telecom, was one of the earliest 5G movers in Latin America — so a cheap plan here does not mean a slow connection.

Uruguay's networks
Antel, Claro and Movistar serve Uruguay. Antel is state-owned, has the widest coverage and leads the 5G rollout in Montevideo and Maldonado. Flysimio routes through Claro, which is strong across Montevideo, the coast and the main highway network. Uruguay is small and flat, so national coverage is unusually consistent.
Timing: the summer runs December to February
Worth stating plainly, since it catches northern-hemisphere visitors out. Uruguay's summer is December to February, and that is when Punta del Este goes from a quiet resort town to one of the busiest beach destinations in South America. Two practical consequences:
- Punta del Este and José Ignacio have 5G in peak season, but the network is heavily loaded in January — expect slower real-world speeds than the signal bars suggest.
- Outside December to February the coast is genuinely quiet and much cheaper. Montevideo and Colonia are worth visiting year-round.
Coverage by destination
- Montevideo — 5G across Ciudad Vieja, the Rambla waterfront and Carrasco airport.
- Punta del Este and José Ignacio — 5G in season.
- Colonia del Sacramento — 4G across the UNESCO old town; the Ruta 1 from Montevideo has continuous 4G.
- Atlantic coast (Rocha, La Paloma) — 4G along the coast road.
- Cabo Polonio — 3G only. No vehicles and no mains electricity; access is a 4WD ride over dunes. Treat it as semi-offline, which is rather the point of going.
- Interior (Tacuarembó, Rivera, Durazno) — 4G on the main routes.
How much data do you need?
Uruguay is compact and Wi-Fi is widespread, so a week between Montevideo, Colonia and Punta runs 2–3 GB for most travellers. Buy 3 GB at $17.38 for a week or 5 GB at $27.50 for a fortnight.
Setting it up
- Buy and install on Wi-Fi before you fly.
- Switch the line on at Carrasco and enable Data Roaming for that line only.
- Turn Data Roaming off on your home line.
- If you are arriving by ferry from Buenos Aires, switch the Uruguayan line on before you dock at Colonia or Montevideo.
- Uruguay uses the peso uruguayo, and card acceptance is good in the cities.
Frequently asked questions
What is the best eSIM for Uruguay?
Flysimio on Claro — 5 GB for 30 days is $27.50 against $87.00 for Airalo's cheapest 30-day Uruguay plan, which is unlimited-only. For a week-long trip the 3 GB plan at $17.38 is usually plenty.
Is there 5G in Uruguay?
Yes. Antel, the state telecom, was an early 5G mover in Latin America, and there is 5G in Montevideo, Maldonado and Punta del Este. Uruguay has unusually good infrastructure for its size.
Does my eSIM work in Cabo Polonio?
Only on 3G. Cabo Polonio has no road access, no vehicles and no mains electricity — you reach it by 4WD over the dunes. Plan it as a semi-offline stop, which is largely why people go.
When is the best time to visit Uruguay?
December to February is Uruguayan summer and peak season on the coast, when Punta del Este is busiest and most expensive. Shoulder months are quieter and cheaper, and Montevideo and Colonia are year-round destinations.
Will my eSIM work travelling from Argentina to Uruguay?
A Uruguayan plan only works in Uruguay, so switch it on when you dock at Colonia or Montevideo if you are crossing by ferry from Buenos Aires. If you are visiting both countries, a South America regional plan may be simpler than two country plans.
