Jetpac does not provide a truly unlimited data eSIM for the United Kingdom. The plans that carry the word “Unlimited” in their name give 3GB of high‑speed data per day and, once that daily limit is reached, the speed is throttled to 1000kbps. This means the data allowance is capped and the plan is not unlimited.
Travelers who need a larger data allowance can choose Jetpac’s fixed data plans. For example, a 40GB plan is available for 30 days at $29.99, and a 30GB plan is available for 30 days at $25.00. These plans offer a fixed amount of high‑speed data without the daily throttling that applies to the “Unlimited” plans, and they can be more cost‑effective for most users.
