NextSIM does not provide genuinely unlimited data plans for Kazakhstan. All plans that carry “Unlimited” in their name still have a fixed data allowance – for example, eSIM Unlimited Standard 1 Day Kazakhstan gives 1 GB of high‑speed data and after that the speed drops to 512 kbps. The same pattern applies to the other “Unlimited” offerings, which are actually daily caps of 1 GB or 2 GB with throttling once the limit is reached.
If a traveler wants a larger, uninterrupted data supply, nextSIM offers fixed data plans that can be more cost‑effective for heavy usage. The eSIM 100 GB 30 Days Kazakhstan plan gives 100 GB for $103.98, and the eSIM 50 GB 30 Days Kazakhstan plan provides 50 GB for $59.62. Daily plans are also available, such as the 1 GB/day and 2 GB/day options that span 1–30 days in validity. These alternatives allow users to choose a fixed amount of high‑speed data without the speed throttling that accompanies the “Unlimited” labeled plans.
