AlpineSIM eSIM Data Plans for Antigua and Barbuda

AlpineSIM does not provide a truly unlimited high‑speed eSIM for Antigua and Barbuda. The plans that carry the word “Unlimited” actually grant a fixed amount of data per day—ranging from 500 MB/day to 5 GB/day—and after the limit is reached the speed is throttled.

If you need more data, AlpineSIM offers fixed‑data eSIMs with larger allowances. For example, a 20 GB plan is valid for 30 days and costs $106.64, a 10 GB plan is also valid for 30 days and costs $54.76, and a 5 GB plan is available for 30 days at $35.00. These options may be more cost‑effective for travelers who require more than the daily limits on the “Unlimited” plans.

AlpineSIM does not offer eSIM plans that include a local phone number or SMS capability for Antigua and Barbuda. The available plans are data‑only, so travelers will not receive a local number or the ability to send or receive text messages directly through the eSIM.

Users who need voice or messaging can rely on internet‑based services such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or limit certain VoIP services, so travelers should confirm that the apps they rely on are accessible in Antigua and Barbuda before buying a plan.

AlpineSIM offers 38 single‑country plans and 28 multi‑country plans that include Antigua and Barbuda. The catalog spans a price range from about $4.05 to $1, 033.38 and data allowances between 500 MB and 20 GB, with plans lasting from one to thirty days. Some options deliver a fixed data amount for the entire validity period, while others reset a daily data cap. Tethering is permitted on certain plans.
