AlpineSIM eSIM Data Plans for Antigua and Barbuda

AlpineSIM does not offer a truly unlimited data eSIM for Antigua and Barbuda. All listed plans have a hard data cap and a fixed validity period – for example, the 20GB/30Days plan provides 20GB of high‑speed data over 30 days, and the 10GB/30Days plan offers 10GB over the same timeframe.

If you need a large amount of data, you can choose one of the available fixed data plans. For instance, the 5GB/30Days plan delivers 5GB in 30 days, while the 20GB/30Days plan gives 20GB in the same period. These fixed plans are typically more cost‑effective than a truly unlimited option, unless you anticipate using data well beyond the allocated allowance.

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.
