Suriname has two main mobile operators: Telesur (government-owned, the dominant carrier) and Digicel Suriname. HelloRoam eSIMs connect via partner networks where available.
4G LTE is available in Paramaribo and the coastal strip extending from Nieuw Nickerie in the west to Albina near the French Guiana border. Commewijne district just east of Paramaribo has some 4G coverage. The Brokopondo district and the Surinamese interior, including the Central Suriname Nature Reserve, have no mobile coverage.
Rivers and jungle lodges south of Paramaribo are beyond network reach. Brownsberg Nature Park, about 130 km south of Paramaribo, has very limited signal at the park entrance. The Maroon villages along the Suriname River and Marowijne River are outside coverage areas.
