eSIMsData does not provide an unlimited‑data eSIM for Montenegro. All of its plans have a hard cap, whether the caps are expressed as a daily allowance (e.g., 1 GB/day or 2 GB/day) or as a total bundle (e.g., 50 GB for 30 days or 100 GB for 30 days).
Travelers who need a large amount of data can choose among the fixed data plans eSIMsData offers. For example, the Montenegro 100 GB 30 days plan gives 100 GB of high‑speed data for a month, and the Montenegro 50 GB 30 days plan offers half that allowance at a lower price. These options provide a set data amount without the “unlimited” terminology, while still allowing reasonable data consumption for the validity period.
