Prepaid Data Plans for Saint Barthélemy Travel
esimbloom lists 22 prepaid eSIM plans for Saint Barthélemy from $0.68 (the smallest is 1GB for 7 days). Every plan is data-only — mobile internet for maps, messaging and bookings, but no local phone number or SMS — and prepaid: pay once, no contract, no roaming charges.
Your eSIM connects to established mobile infrastructure across the island. Service runs on the local mobile network at whatever speed it and your device support. You pay once upfront, receive your QR code by email within minutes, and use exactly the data you purchased with no surprise charges.
How to Activate Your Saint Barthélemy eSIM
Before you fly, check that your phone supports eSIM technology—most iPhones from XS onward and recent Android flagships do. After purchasing, you will receive a QR code by email. Install the eSIM while you still have Wi-Fi by scanning the code in your phone's settings, but do not activate the plan yet.
Turn on your eSIM and enable data roaming once you land in Saint Barthélemy. Your plan validity starts the moment the eSIM first connects to the network. Keep your home SIM installed if you need to receive verification codes or calls; your phone will route mobile data through the eSIM and calls through your primary line.
Staying Online in Saint Barthélemy
Saint Barthélemy is a small island—just 25 square kilometres—and mobile coverage reaches most inhabited areas including Gustavia, St. Jean, and the main resort zones along the northwest and eastern coasts. You will find reliable connectivity in hotels, beaches, and restaurants. Hilly interior areas and more remote coves may see weaker signal, but most travellers stay within well-covered zones.
