No. An eSIM can be installed only once, and it locks to the first device it is installed on. It cannot be moved to another phone, re-scanned, or reinstalled afterward, and it is non-refundable once installed. Please install your eSIM on the device you plan to keep using. If you are switching devices and need help, contact our support team.

It's crucial for travelers to note that Antigua & Barbuda is an independent nation and is not part of any domestic roaming zones for US, UK, or Canadian carriers. Relying on your home SIM from providers like Verizon, T-Mobile, Rogers, or O2 will almost certainly lead to expensive international roaming charges, often billed as costly daily passes. WorldESIM provides a dedicated and budget-friendly data solution for Antigua & Barbuda, ensuring you can enjoy seamless connectivity on both islands without the worry of excessive fees, keeping your focus on the beautiful Caribbean experience.

Yes, absolutely. WorldESIM ensures comprehensive coverage across both islands of Antigua & Barbuda with a single, convenient plan. Whether you're enjoying the vibrant atmosphere of Dickenson Bay in Antigua, taking a scenic ferry or flight, or relaxing on the serene pink sand beaches of Barbuda, your WorldESIM will maintain a strong and reliable signal. This integrated coverage is ideal for travelers exploring the full beauty of this twin-island nation, allowing you to stay connected wherever your Caribbean adventure takes you.

WorldESIM is an excellent solution for cruise passengers seeking affordable and reliable connectivity during port calls. Unlike expensive, often slow, satellite-based ship Wi-Fi, your WorldESIM will instantly connect to the local 4G network the moment your ship docks in St. John's, Antigua. This allows you to explore the port, use navigation apps to discover local attractions like Nelson's Dockyard, communicate with ease, and share your experiences without incurring exorbitant costs. Enjoy seamless, high-speed data from the moment you step ashore.

For ultimate mobility and privacy, WorldESIM's mobile data offers a significant advantage over typical all-inclusive resort Wi-Fi. While resorts like Sandals provide Wi-Fi, it can often be shared, leading to slower speeds, and coverage might be limited to common areas. A personal WorldESIM connection provides a private, fast 4G/LTE signal that follows you everywhere – from your room to the beach, by the pool, or while exploring local markets. Enjoy consistent, secure connectivity for all your digital needs, ensuring a seamless and worry-free travel experience.

To ensure you receive the best possible speed and coverage across both Antigua and Barbuda, WorldESIM partners with the leading local network providers, typically Digicel or Flow. These partnerships guarantee access to fast and reliable 4G/LTE speeds, essential for navigating the islands with Google Maps, making video calls to family, or sharing your stunning Caribbean photos. Our commitment is to provide robust connectivity, allowing you to fully enjoy every moment of your journey without interruption.

To ensure a smooth experience with WorldESIM, it's essential to confirm your device's eSIM compatibility.

This will help you verify that your specific phone model is ready for global connectivity before you embark on your multi-country adventure.

For a smooth arrival experience, we recommend scanning and installing your WorldESIM QR code while you still have a stable internet connection at home or during a layover. This ensures your data is ready the moment you land at V.C. Bird International Airport (ANU), letting you immediately access maps, ride-shares, or communicate with your accommodation without searching for public Wi-Fi.
