Stellar eSim does not provide a true unlimited data eSIM for the United Kingdom. Every plan that carries the word “Unlimited” in its name has a data cap of 3GB and a validity period ranging from 1 day to 60 days. After the 3GB allowance is reached the plan is not designed to continue providing high‑speed data without limits.
If a traveler needs more data, Stellar eSim offers fixed data plans such as the 100GB 30‑day plan, the 100GB 60‑day plan, and the 50GB 30‑day plan. These plans give a larger, hard‑cap data allowance for a set number of days and can be more cost‑effective for users who consume a lot of data.
