How is SouthESIM coverage on St. Barths' more rugged coastlines, like Grand Fond or Toiny?

When you're exploring the wilder side of St. Barths, like the scenic areas around Grand Fond and Toiny, SouthESIM generally provides good signal along the main coastal roads. However, if you venture off onto the more secluded, rocky hiking trails or hidden coves, the connection might become a bit spotty. We recommend downloading offline maps or content before heading out to those truly off-the-beaten-path spots, just in case!
