Why choose a SimFuse eSIM for St. Barthélemy?

Do I set up before travel or on arrival in St. Barthélemy?

Set up before you travel. Install the eSIM at home over Wi-Fi - it uses no data and won't start your plan. The validity clock only begins when the eSIM first connects to a network in St. Barthélemy, so you can have everything ready days in advance and simply land connected.

How much data do I need for St. Barthélemy?

For a typical trip to St. Barthélemy: around 1GB per week covers maps and messaging, 3–5GB per week suits everyday browsing and social media, and 10GB or more is best if you stream, video call often or use your phone as a hotspot. You can always top up instantly in the app if you run low - no need to reinstall the St. Barthélemy eSIM.

Will I pay roaming charges in St. Barthélemy?

No. You pay one upfront price for your St. Barthélemy data plan and that's the end of it. There are no per-megabyte roaming fees and no bill waiting for you when you get home - the single biggest reason travellers switch from carrier roaming to a SimFuse eSIM.

Frequently asked questions

eSIMs in general
What is an eSIM?

An eSIM is a digital SIM built into your phone - there is no plastic card to insert. You download a data plan over the air and your phone connects to a local network instantly. Most phones released since 2018 support eSIM.

How does a travel eSIM work?

You buy a plan, install the eSIM with a QR code or directly in the SimFuse app, and it connects to a partner network at your destination. Your home SIM stays active for calls and texts, while the eSIM handles your data.

Is my phone compatible with an eSIM?

Most phones from iPhone XS / XR (2018) onward, plus recent Samsung Galaxy, Google Pixel and many other models, support eSIM. Open Settings and look for 'Add eSIM'. Your phone must also be carrier-unlocked.

When does my data plan start - at purchase or on arrival?

Validity begins when the eSIM first connects to a network at your destination, not when you buy or install it. Installing at home over Wi-Fi uses no data, so you can set everything up before you fly.

Can I keep my regular phone number?

Yes. SimFuse travel eSIMs are data-only and run alongside your physical SIM, so your home number stays active for calls and texts. You simply set the eSIM as your data line while travelling.

Can I make calls and send texts?

SimFuse plans are data-only, but you can call and message over WhatsApp, FaceTime, iMessage, Telegram and any other app using your data. Your home SIM remains available for traditional calls and SMS.
