MoodSIM does not provide a truly unlimited data eSIM for Guernsey. The plans that carry “Unlimited” in their name are actually daily‑capped: after 500 MB, 1 GB, or 2 GB of high‑speed data per day the speed drops to 384 kbps. For travelers who need more data without a daily cap, MoodSIM offers fixed data plans such as 50 GB for 180 days or 20 GB for 30 days, both with 5G coverage in Guernsey. These fixed plans can be more cost‑effective for most users, while the capped “Unlimited” options provide a larger daily allowance at a lower price.
