Simbye does not provide a truly unlimited high‑speed eSIM plan for Hungary. The plans that carry “Unlimited” in the name give 2GB of high‑speed data per day and, once that amount is used, the internet speed is reduced to 1000 kbps.
Instead, travelers can choose from several fixed‑data options, such as the Hungary Unlimited 7‑, 15‑, or 30‑day plans that each offer 2GB/day, or the larger fixed‑data bundles like Hungary 50GB for 180 days or Hungary Orange Holiday 100GB for 30 days. These plans allow a predictable data allowance and may be more cost‑effective unless an extremely heavy data user requires truly unlimited traffic.
