Gustavia (the capital harbor) has 4G. St Jean Beach (the main resort strip) has strong 4G. The island is only 25km² — coverage is consistent across the main populated areas. Remote hilltop roads and some secluded beaches have variable signal. The ferry route from St Maarten loses signal on open water and reconnects approaching Gustavia harbor.
