eSimfly does not provide a truly unlimited data eSIM for Hungary. All plans that carry “Unlimited” in their name have a fixed data allowance, such as 3GB per day or a total of 35GB for 30 days, after which the speed is reduced to 1000kbps.
Travelers who need a large amount of high‑speed data can choose from eSimfly’s fixed data plans. Examples include the Hungary Unlimited 30 days plan with 3GB/day, the O2 Unlimited (International) plan offering 35GB for 30 days, and the Bouygues Telecom 120 GB plan for 30 days. These fixed‑data options are often more cost‑effective unless a user requires an extremely high volume of data.
