What you get with an Antigua and Barbuda eSIM
All ten plans are data-only and prepaid, so you pay once and there are no surprise charges. The smallest bundle offers 500MB valid for 1 day, and larger options cover longer stays and heavier use. You'll have mobile data across Antigua, Barbuda, and the smaller islets in between, using 4G/LTE or 5G where the underlying network and your device support it.
Because these are data plans, you won't receive an Antiguan or Barbudan phone number. You can still use WhatsApp, iMessage, FaceTime, email, maps, and any app that works over the internet. For ride-hailing, restaurant bookings, or checking ferry times, data is all you need.
Installing and activating your eSIM
Once you complete your order, the QR code arrives by email within minutes. You can install the eSIM profile before you leave home by scanning the code in your phone's settings, but leave it switched off until you reach Antigua and Barbuda. When you arrive, turn on the eSIM and data roaming, then turn off your home SIM to avoid accidental charges.
Your device must be carrier-unlocked and eSIM-compatible. Most iPhones from the XS onward, recent Samsung Galaxy and Google Pixel models, and many other flagships released in the past few years will work. Check your manufacturer's list if you're unsure, and make sure your phone is not locked to a carrier back home.
Staying connected across Antigua and Barbuda
Coverage is strongest in and around St. John's, English Harbour, Jolly Harbour, and the resort zones along the northwest and west coasts of Antigua. Barbuda's main settlement, Codrington, and the ferry dock have reliable service, though signal may thin out on remote beaches and the eastern lagoon. The road between VC Bird International Airport and most hotels has consistent coverage, so maps and messaging work as soon as you leave the terminal.
If you're island-hopping by ferry, downloading offline maps before departure is sensible because signal drops mid-crossing. Day trips to Nelson's Dockyard, Shirley Heights, or Half Moon Bay use minimal data for photos and light browsing; streaming video or uploading large files is best saved for WiFi at your hotel or a café. A 500MB plan suits a short stay with WiFi backup, while multi-day visitors who rely on maps, social media, and ride-hailing apps should consider a larger bundle.
Frequently asked questions
Do eSIMs work on both Antigua and Barbuda?
Yes. The plans cover the entire nation, including both main islands and the smaller cays. You won't need to buy separate plans or switch profiles when you take the ferry from Antigua to Barbuda.
Can I use my eSIM as soon as I land at VC Bird Airport?
Yes, as long as you installed the eSIM profile before arrival and turn it on once you land. You can also install it after clearing customs if you have airport WiFi, then activate immediately.
Will my eSIM give me a local phone number?
No. These are data-only plans, so you won't receive an Antiguan or Barbudan number and cannot make regular voice calls or send SMS. Internet-based calling and messaging work normally.
Which network will my eSIM use in Antigua and Barbuda?
That depends on the specific plan you purchase. esimbloom sources wholesale capacity from multiple providers, so the underlying network varies. All plans deliver mobile data across both islands using 4G/LTE or 5G where supported.
How much data do I need for a week in Antigua and Barbuda?
Light use—maps, messaging, and occasional photo uploads—usually fits within one to two gigabytes per week. If you stream music, upload video, or work remotely without WiFi, consider three gigabytes or more. Most hotels and restaurants offer WiFi to reduce mobile data consumption.
