Uruguay has three main mobile operators: Antel (state-owned, dominant), Movistar Uruguay, and Claro Uruguay. Antel has the widest coverage and is widely rated the best network. HelloRoam eSIMs connect via Antel or its partner networks.
Uruguay has excellent mobile infrastructure by South American standards. Antel launched 5G in Montevideo in 2024, making Uruguay one of the first countries in the region to deploy commercial 5G. 4G LTE covers Montevideo, Punta del Este, Colonia del Sacramento, Salto, Paysandú, and most cities and towns.
The Route 1 coastal highway from Montevideo west toward Colonia and the Route 9 east toward Punta del Este both have continuous 4G coverage. The Atlantic beach towns of La Paloma, Cabo Polonio, and Punta del Diablo, popular with backpackers and surfers, have 4G in the main town centers.
Cabo Polonio, a remote cape reachable only by 4WD truck and known for its sea lions and isolated atmosphere, has very limited to no mobile coverage. The national park area around Cabo Polonio is intentionally low-development. Download offline maps before the truck ride in. The interior farming regions have solid rural 4G on main roads. Australian travellers should confirm their handset is unlocked and supports the local network bands.
