Yesim offers unlimited data eSIMs for Antigua and Barbuda. The provider sells a 1‑day unlimited plan priced at $13.80 USD and two Global Plus unlimited plans for 7 days and 15 days, priced at $74.73 USD and $113.81 USD respectively. All of these plans are labeled as unlimited and allow tethering and are powered by 3G and LTE networks in Antigua and Barbuda.
Because the data cap is unlimited, speed may be throttled after significant usage in accordance with a Fair Usage Policy. While the plans promise unrestricted data, the quality of service can be reduced when a certain threshold of data is exceeded. Travelers who are concerned about potential speed restrictions should contact Yesim directly to confirm whether a Fair Usage Policy applies and to learn the typical amount of data remaining at normal speed.
