Frequently Asked Questions
No! This is the #1 roaming trap. Antigua and Barbuda is an independent country and is NOT part of the EU, UK, or US domestic plans. Most home carriers (like AT&T, Verizon, T-Mobile, or UK's Vodafone/O2) will charge you expensive international "Day Pass" rates (e.g., $10-$15 per day). A Cellesim eSIM is a one-time prepaid fee that is significantly cheaper.
Yes, absolutely. This is the most important question for visitors. Our eSIM plan covers both islands with one single purchase. You can have a strong signal at Dickenson Bay (Antigua), take the ferry/flight, and stay connected on the pink sand beaches of Barbuda.
Yes, perfectly. This is the ideal solution for cruise passengers. Your cruise ship's Wi-Fi is satellite-based and expensive. The moment your ship docks in St. John's, your eSIM will connect to the local 4G network. This allows you to leave the port, use Google Maps (for your taxi), and upload your beach photos for the day.
Yes, for mobility and privacy. Most luxury resorts (like Sandals) offer Wi-Fi, but it is often slow, shared with all guests, and only works in the lobby. A personal eSIM gives you a private, fast 4G/LTE connection that works everywhere, in your room, by the pool, and, most importantly, when you leave the resort to explore.
To give you the best speed and coverage on both islands, our eSIM connects to the premium local providers, typically Digicel or Flow. This ensures you get the fastest available 4G/LTE speeds for using Google Maps or making WhatsApp calls from your hotel.
Scan it at home before your flight. This ensures you get immediate data the moment you land at V.C. Bird International Airport (ANU) without searching for free WiFi.
Connect to any airport or hotel WiFi in Antigua and Barbuda and contact our 24/7 support via WhatsApp or Email immediately.
Yes, Google Maps works well across the island. Reliable data is essential for navigating the winding roads to English Harbour or remote beaches.

Signal is strong at the docks but may drop temporarily in the middle of the open ocean crossing between St. John's and Barbuda.
