4S eSIM does not currently offer an unlimited data eSIM for Antigua and Barbuda.
The available options are fixed data plans, such as the 40GB plan valid for 365 days and several 20GB plans ranging from 5 to 30 days. These plans provide coverage across Antigua and Barbuda and allow consistent speeds through the local network. Choosing a fixed data plan can be more cost‑effective for most travelers unless the user requires very high data consumption beyond the provided allowances.
4S eSIM does not offer an eSIM plan for Antigua and Barbuda that includes a phone number or SMS capabilities. Only data‑only plans are available from this provider for the island nation. Travelers can still use voice and messaging services via popular VoIP applications such as WhatsApp, Telegram, or iMessage, which operate over the data connection without requiring a local phone number or SMS support.
4S eSIM offers 25 single‑country data plans that cover Antigua and Barbuda, and 87 multi‑country plans that include the island nation, for a combined total of 112 available data plans. The available plans range in price from $4.05 to $329.64 and provide data caps between 500 MB and 40 GB, with validity periods spanning 1 to 365 days. None of the listed plans specify a daily data cap, so all data capacities are fixed for the duration of the plan.
