nextSIM eSIM Data Plans for Antigua and Barbuda

nextSIM does not provide a true unlimited data eSIM for Antigua and Barbuda. All plans that carry the word “Unlimited” in their name are actually fixed‑data packages—each offers either 1GB or 2GB of high‑speed data, after which the speed is throttled to 512kbps or 2000kbps. The data is capped, so it is not an unlimited high‑speed plan.

Travelers looking for larger data allowances can choose from nextSIM’s fixed‑data options. For example, the eSIM Antigua and Barbuda 20GB 30Days Standard plan provides 20GB of high‑speed data for 30 days at a cost of $93.08 USD, while the eSIM GLOBAL 50GB 30Days Premium plan gives 50GB across Antigua and Barbuda and 156 other countries for $1, 289.42 USD. These fixed‑data plans may be more cost‑effective for heavy data users.

nextSIM does not offer an Antigua and Barbuda eSIM that includes a local phone number or SMS capability. Travelers can only buy a data‑only eSIM from this provider for the destination. For voice and messaging, popular VoIP applications such as WhatsApp, Telegram, and iMessage can be used over the data connection.

nextSIM offers a mix of single‑country and multi‑country data plans in Antigua and Barbuda, with 47 single‑country plans and 14 multi‑country plans available. The plans range from as low as $8.64 to $1, 284.00, providing between 1 GB and 50 GB of data and valid for 1 to 365 days. Some plans set a fixed data amount, while others cap usage on a daily basis—this allows travelers to choose a plan that fits short‑term bursts of use or longer stays with a predictable data allowance.
