Simsima eSIM Data Plans for Antigua and Barbuda

Simsima does not provide a truly unlimited data eSIM for Antigua and Barbuda. The only plan that carries the label “Unlimited” is the “Unlimited – 7 days” plan, which offers 3GB of high‑speed data per day and reduces the speed to 1000kbps after that daily limit is reached.

Travelers who need more data can choose from Simsima’s fixed data plans. For example, the 20GB plan valid for 30 days and the 20GB plan valid for 365 days both provide 5G coverage and include 20GB of high‑speed data. A 10GB plan valid for 30 days is also available. These fixed data plans give a larger data allowance than the daily‑limited “Unlimited” plan and may be more cost‑effective for most users, unless a traveler expects to use data beyond the fixed limits.

Simsima does not offer an Antigua and Barbuda eSIM plan that includes a phone number or SMS capability. The provider only sells data‑only eSIMs for this destination. Travelers who need voice or text communication can still use VoIP services such as WhatsApp, Telegram or iMessage over the data connection, but they should verify that these apps work in Antigua and Barbuda before purchasing.

Simsima provides seven single‑country data plans and thirteen multi‑country data plans that include Antigua and Barbuda. The plans cover a price range from $5.63 to $84.83 and offer data caps between 1 GB and 20 GB, with validity periods that vary from five days to one year. Some of the offerings are fixed data caps, meaning the amount of data is set for the entire validity period, while a smaller subset of plans are daily data cap plans that allow a set amount of data each day, after which the connection may be slowed or turned off.
