MeSIM does not provide a truly unlimited‑data eSIM for the Baltic countries. All of the Baltic‑coverage plans listed in the MeSIM catalogue have a hard data cap, expressed as a daily high‑speed allowance (for example 500 MB/day, 1 GB/day, 2 GB/day, or 3 GB/day). After the high‑speed limit is reached, the connection speed drops to 512 kbps or 384 kbps, depending on the specific plan.
Travelers who need more data can choose from a range of fixed‑data plans. For instance, a 7‑day plan with 1 GB/day high‑speed data is available for $11.65, while a 3‑day plan with 3 GB/day high‑speed data costs $12.15. These fixed‑data options are often more economical for moderate to heavy data users, but they still impose a maximum data allowance rather than offering unlimited data.
