PikaSim does not provide an unlimited data eSIM for Montenegro. All of its available plans for the country are fixed‑data packages that contain a hard cap of 20GB of high‑speed data. For example, the Montenegro 20GB 30Days plan offers 20GB of data for 30 days, and similar 20GB packages with 30‑day and 90‑day validity are also available for Montenegro or as part of a larger regional bundle. Because the data cap is fixed, the plans may be more cost effective for most travelers, especially those who do not need very high data usage. If a traveler requires a larger or unlimited data allowance, PikaSim currently does not have such a plan for Montenegro.
