No. eSIMNEXA does not offer an unlimited data eSIM plan for Kazakhstan. The highest bundle available is a fixed‑data plan that provides 60GB of data for 30 days. Other sizable options include 30GB for 30 days, 20GB for 15 days, and 20GB for 30 days, all of which have a set validity period. These fixed plans may be more cost‑effective for most travelers, though a very heavy data user might need a larger bundle.
