Why an eSIM is Recommended for Antigua and Barbuda
No Free EU Roaming
Unlike European countries, Antigua and Barbuda has no free EU roaming. Your home plan will be expensive: between $2 and $5 per MB depending on your carrier. For a one-week trip with moderate usage (browsing, social media), you can easily spend $50-$100 on roaming.
Free WiFi vs eSIM
Free WiFi is available in hotels and resorts in Antigua and Barbuda, but it has drawbacks:
- Security: unsecured public networks, hacking risks
- Reliability: unstable connections, frequent dropouts
- Mobility: can't use while exploring beaches, sailing, or traveling between islands
An eSIM offers secure, reliable connectivity everywhere, even in remote areas.
