Qrispy eSIM does not provide a true unlimited data eSIM for Guernsey. The only options listed are pay‑as‑you‑go plans, with data amounts of 1GB, 2GB, 3GB, 5GB, or 10GB. These plans pre‑load a balance that the traveler can use at any time; the prepaid credit does not expire, so unused data can be carried forward. Because the plans are pay‑as‑you‑go, the traveler pays only for the data actually used and can purchase additional credit whenever required, making them a flexible alternative to a fixed unlimited offering.
