MeSIM’s packages for Poland are not truly unlimited. Each plan lists a specific daily high‑speed data allowance, such as 500MB/day, 1GB/day, 2GB/day or 3GB/day, and once that amount is used the connection speeds down to a throttled rate of up to 384kbps. The term “unlimited” in the plan names refers to the absence of a rolling validity period, not to an unlimited data volume.
Travelers who need more data can choose from fixed‑data plans that provide large daily allowances, for example a 3GB/day plan valid for 3 to 60 days, or the orange‑holiday products that offer 200GB for 30 days or 500GB for 90 days. These alternatives give a set amount of high‑speed data and are typically more cost‑effective for most users unless a traveler requires extremely high volumes of data.
