Stellar eSim does not provide a truly unlimited data eSIM for Guernsey. The plans that carry the “Unlimited” label in their name are actually fixed data plans with a 2GB high‑speed allowance that expires after the stated validity period. After the 2GB limit is reached the speed is reduced.
Travelers can instead choose from the fixed data plans listed for Guernsey, such as the 50GB plan valid for 90 days or the 30GB plan valid for 60 days. These plans offer larger high‑speed data allowances and can be more cost‑effective for longer stays.
