Simsima eSIM Data Plans for Antigua and Barbuda

Simsima does not provide a true unlimited‑data eSIM for Antigua and Barbuda; the only plan labeled “Unlimited” offers 3 GB of high‑speed data per day for 7 days before the speed drops to 1000 kbps. Travelers can instead choose from fixed‑data options such as the 20 GB plan valid for 30 days, which delivers high‑speed 5G data throughout Antigua and Barbuda, or the 10 GB 30‑day plan that offers ample data at a lower cost. These fixed‑data plans may be more economical for most users, unless a very heavy data usage scenario justifies the limited high‑speed allowance.

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 offers 10 single‑country data plans and 14 multi‑country data plans for Antigua and Barbuda. The plans come in two main styles: fixed data amounts ranging from 500 MB up to 20 GB, and daily data caps that allow a set amount of data each day over the validity period. Prices for these plans span from about $5.63 to $152.63, giving travelers options at both the lower‑cost and higher‑capacity ends of the market. Validity periods vary from 5 to 180 days, and some plans may include reduced speed options of 512 kbit/s or 1 Mbit/s.
