Giga.Tel does not provide a truly unlimited data eSIM plan for travelers to the Cayman Islands. The only plan that includes “Unlimited” in its title is the Global(Not Include Mainland China) 15 days(1GB/Day Unlimited) offering 1 GB of high‑speed data per day for 15 days; once the 1 GB per day limit is reached, traffic is throttled to 512 kbps.
Instead, Giga.Tel offers fixed‑data options for the Cayman Islands, such as the Caribbean 10 GB plan valid for 30 days, a 20 GB plan valid for 3 days, and a 5 GB plan valid for 7 days. These plans provide a larger pool of high‑speed data without the high‑speed restriction that applies only after a limited amount of data is used. For most travelers, selecting a fixed data plan can be more cost‑effective than relying on a plan that advertises unlimited usage but in reality imposes a speed cap.
