ZenSim eSIM Data Plans for Antigua and Barbuda

ZenSim does not provide a truly unlimited high‑speed data eSIM for Antigua and Barbuda. The only plan that carries “Unlimited” in its name is the Antigua and Barbuda Unlimited STANDARD – 5 Days, which supplies 3 GB per day for five days, functioning as a capped offer rather than an open‑ended unlimited service.

Instead, ZenSim offers fixed‑data plans that can be more economical for most travelers. For example, the Antigua and Barbuda 20 GB plan is available for 15 days at $60.00 USD or for 30 days at $66.00 USD, and the 10 GB plan is available for 15 days at $42.00 USD. These fixed plans include tethering and cover the entire country. If a traveler needs extended or higher‑volume data, selecting one of these fixed plans is generally more cost‑effective than pursuing an unlimited‑named but capped option.

ZenSim does not provide eSIM plans that include a local phone number or SMS capability for Antigua and Barbuda. Travelers can purchase only data‑only eSIMs from ZenSim for that destination, and any voice or messaging needs can be met by using VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection.

ZenSim has 10 single‑country plans that can be used in Antigua and Barbuda, and, in addition, 10 multi‑country plans that also cover the island nation as part of a broader network. The plans vary in cost from roughly $10 to $84 USD; data caps range from 1 GB to 20 GB, and validity periods are between 5 and 30 days. Some of the offerings are daily‑data‑cap plans, allowing a set amount of data each day, while others are fixed‑data‑cap plans that provide a single prepaid data allotment for the entire validity period. All ZenSim plans may include tethering, depending on the specific option chosen.
