Lotso Travel does not provide a truly unlimited high‑speed data eSIM for Montenegro. All of the listed plans have a hard data cap that must be used within the validity period; once the cap is reached the connection remains active but the speed is throttled (generally to 128kbps, though variations of 384kbps or 5.1Mbps also exist).
Travelers seeking large amounts of data can choose from several fixed‑data plans. For example, the 90GB Unlimited eSIM – 30 day plan gives 3GB of full‑speed data per day before the connection reduces to 128kbps, and the 60GB Unlimited eSIM – 30 day plan offers 2GB per day before throttling. These options illustrate the breadth of high‑volume bundles available, but they do not deliver unlimited high‑speed usage.
