JamboSim eSIM Data Plans for Antigua and Barbuda

JamboSim does not provide a true unlimited‑data eSIM for Antigua and Barbuda. The only plan labeled “Unlimited” offers 3 GB per day of high‑speed data and then throttles the speed to about 1 Mbps after the daily allowance is reached, so it is a capped plan with reduced speed once the limit is exceeded.

For travelers who need more data without daily limits, JamboSim offers several fixed data plans. For example, the “eSIM JamboSim Global 20GB / 30 Days” provides 20 GB of high‑speed data for 30 days, and the “eSIM JamboSim Global 10GB / 30 Days” gives 10 GB for the same period. These fixed data bundles can be more cost‑effective for most visitors.

JamboSim offers Antigua and Barbuda eSIM plans that include a phone number and outbound SMS capability. The available plans range from 1 GB for 7 days, priced at $11.99 USD, up to 20 GB for 365 days, priced at $105.99 USD. Each plan provides a local phone number with dialing code +1 and allows outbound calls and outbound SMS. The numbers are from the +1 country code and are not local Antigua and Barbuda numbers, but they enable communication to and from the destination. Users should confirm specific call and SMS availability directly with JamboSim if they need particular functionalities.

JamboSim provides 24 multi‑country data plans that include Antigua and Barbuda. These plans are split into one daily data‑cap offering and twenty‑three fixed data‑cap options. Prices for the bundle range from about $1.99 to $99.99, while the data caps span from 200 MB up to 20 GB, giving travelers a broad selection of budgets and usage levels.
