Jamaica has two main mobile operators: Digicel Jamaica and Flow (Cable and Wireless). HelloRoam eSIM plans connect via partner networks with 4G LTE across the island's main corridors.
Montego Bay has strong 4G in the airport, the Hip Strip, and all major resort areas. Kingston, the capital, has good urban coverage across New Kingston, Half Way Tree, and the Port Royal area. The north coast highway from Montego Bay through Falmouth to Ocho Rios has consistent 4G along the road. Negril's seven-mile beach strip and the town center have solid coverage.
The Blue Mountains inland from Kingston have weaker signal at higher elevations. The interior parishes of Manchester and Clarendon have 4G in main towns but lighter coverage on rural roads. Port Antonio on the northeast coast has 4G in the town and marina area. Grand-Anse Beach and remote river valleys in the John Crow Mountains have minimal to no coverage.
