eSimfly eSIM Data Plans for Antigua and Barbuda

eSimfly does not provide a genuinely unlimited data eSIM for Antigua and Barbuda. The only plan that carries “Unlimited” in its name, Caribbean Islands Unlimited 7 Days, actually allows 3 GB per day of high‑speed data and then drops the speed to 1000 kbps after that limit is reached, so it is not truly unlimited.

Instead, travellers can choose from fixed data plans that grant a set amount of high‑speed data for a fixed period. For example, eSimfly offers a 20 GB plan valid for 30 days at $48.18 USD and a 20 GB plan with a 365‑day validity for $83.66 USD. Another option is the Vodaf

eSimfly does not provide a truly unlimited data eSIM for Antigua and Barbuda. The only plan that includes “Unlimited” in its name, Caribbean Islands Unlimited 7 Days, actually limits users to 3 GB per day of high‑speed data and then throttles the speed to 1000 kbps once that daily amount is reached, so it is not a no‑cap plan.

Instead, travellers can choose from fixed data plans. For instance, a 20 GB plan valid for 30 days costs $48.18 USD, while a 20 GB plan with a 365‑day validity costs $83.66 USD. Another option with a larger data allowance is the Vodafone Travel (International) plan, which offers 25 GB for 30 days at $43.25 USD. These fixed plans provide a high‑speed data allowance for a set period and can be more cost‑effective than an unlimited plan for most users.

eSimfly does not provide an eSIM plan with a local phone number or SMS capability for Antigua and Barbuda. Travelers who purchase an eSIM from eSimfly for this destination will receive only a data‑only plan; there is no telephone dialing code, inbound or outbound voice service, or SMS service included.

Instead, users can rely on internet‑based communication apps such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations restrict access to certain VoIP services, so it is advisable to confirm that the apps you require will work in Antigua and Barbuda before buying a plan.
