Networks Fuse uses in Saint Martin

Fuse connects to Saint Martin's mobile networks — Dauphin Telecom — switching automatically to whichever has the strongest signal. There's nothing to choose and nothing to set up — your eSIM picks the best available network the moment you arrive in Saint Martin.

Staying connected in Saint Martin

  • No activation needed. Your existing Fuse plan already covers Saint Martin.
  • Use your usual data allowance. Browsing, maps and video calls in Marigot work just like they do at home.
  • No bill shock. When you reach your monthly cap, data simply stops — it never auto-charges.

Travelling on more data? The Surge plan gives you 15 GB a month that works the same way right across Saint Martin.
