Cape Verde’s coverage picture is shaped entirely by island geography — dense and reliable on Sal and Boa Vista’s resort areas, workable in Santiago and São Vicente’s cities, and considerably thinner on quieter islands like Santo Antão, Fogo, Maio, and Brava.
Quick answer: Coverage is strong and consistent on Sal and Boa Vista, the country’s main tourist islands. Praia and Mindelo maintain solid urban coverage on Santiago and São Vicente. Smaller islands like Santo Antão, Fogo, São Nicolau, Maio, and Brava see considerably more limited and inconsistent signal.
