Frequently asked questions
How do I activate an eSIM in St. Barthélemy?
Download the eSIM79 app, pick St. Barthélemy, buy a plan and install the eSIM in one tap. It activates automatically when you arrive — no store visit, no physical SIM.
Does my phone support eSIM?
Most iPhones since the XS, Samsung Galaxy S20 or newer and Google Pixel 3 or newer support eSIM. The app checks your device automatically.
Can I keep my own number?
Yes — the eSIM is data-only and runs alongside your primary SIM, so your number keeps receiving calls and texts.
When does the validity start?
The clock starts on first network connection at your destination, not at purchase — buy safely before you travel.
