Kolet does not offer a truly unlimited high‑speed data plan for Poland. The plans labeled “UNLIMITED” provide up to 5 GB of high‑speed data per day; once that daily limit is reached the speed drops to 1000 kbps. Therefore, data use is still capped even though the plan name includes “Unlimited.”
For travelers who need a larger data allowance, Kolet offers fixed‑data plans such as the Poland 20 GB for 365 days plan, which supplies 20 GB of high‑speed data over a year, or the Poland 10 GB for 365 days plan. These fixed‑data options give a clear data limit and may be more cost‑effective for users who require predictable usage.
