Jetpac does not provide a truly unlimited data eSIM for the United Kingdom. The plans that carry the word “Unlimited” in their name actually deliver 3 GB per day and, once that limit is reached, the data speed is throttled to 1 024 kbps. Because the data is capped in this way, the plans are not unlimited in the strict sense of providing high‑speed data without limits.
Jetpac offers fixed‑data alternatives that may suit heavier users. For example, a 30 GB plan is available for 30 days at $25.00 and a 40 GB plan is available for 30 days at $29.99. These plans give a larger total amount of high‑speed data without the daily cap that applies to the “Unlimited” options.
