eSimfly does not provide a truly unlimited data eSIM for Kazakhstan. The plans that carry “Unlimited” in their name give 3GB of high‑speed data each day; once that daily limit is reached the speed is throttled to 1000kbps, so the data is still capped. If a user needs a larger, hard‑cap allowance, eSimfly offers fixed data plans such as the 50GB 30‑day plan or the 20GB 30‑day plan, which can be more cost‑effective for most travelers while still delivering high‑speed data until the 50GB or 20GB limit is reached.
