MobileSIM eSIM Data Plans for Antigua and Barbuda

MobileSIM does not offer a truly unlimited data eSIM for Antigua and Barbuda. The plan titled “Unlimited data for 7 days” actually provides 3GB per day, after which the speed is reduced to 1000kbps, so it is a capped offer rather than an unlimited one. Travelers who want a larger, but still limited, data allowance can choose from MobileSIM’s fixed data plans, for example the Global 20 GB for 30 days plan, which gives 20 GB of high‑speed data within a 30‑day validity window. The other fixed options include Global 10 GB, Global 5 GB, Global 5 GB for 60 days, and Global 3 GB, all of which provide a set data amount for a specified number of days. These fixed plans can be more cost‑effective for most users unless they have an extremely heavy data requirement.

MobileSIM does not provide eSIM plans for Antigua and Barbuda that include a phone number or SMS capability. Only data‑only eSIMs are offered for that destination. Travelers who need to make calls or send messages can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these services are accessible in Antigua and Barbuda before purchasing, as some destinations may block or restrict certain apps.

MobileSIM has a total of ten data plans that cover Antigua and Barbuda; all of these are multi‑country plans. Among them nine are fixed data cap plans, providing a set amount of data for the duration of the validity period, while one plan operates on a daily data cap, giving a specified amount of data every day of the activation period. Prices for the available plans range from about $2.30 to $66.00, with data caps spanning from 200 MB up to 20 GB and validity periods between 5 and 60 days.
