Supera link does not provide an unlimited‑data eSIM for Kazakhstan. All of its Kazakhstan‑covering plans are fixed‑data plans. One of the options is a 5GB/day plan that can be purchased for 7, 10, 15, 20 or 30 days of validity, with prices ranging from about $42 to $176 USD, and it includes tethering, a reduced speed allowance of 1024kbps, and coverage on 3G, 4G and 5G networks.
Choosing a fixed‑data plan can be more cost‑effective for travelers who do not require constant high‑speed data, but any heavy data consumer may find a plan with a higher daily or total data cap to be a better value.
