Rufly does not offer a truly unlimited high‑speed data eSIM for Montenegro. The plans labelled “Unlimited” provide 500 MB of high‑speed data each day, after which the speed is reduced to 5 Mbps. Once the total usage passes 30 GB (for the 7‑day variants) or 45 GB (for the 15‑day variant), the speed drops further to 512 Kbps.
Travelers who need more data can choose a fixed data plan such as the 7‑day or 15‑day bundles, which include larger daily allowances and a longer validity period. These fixed plans are generally more cost‑effective unless the user requires an extremely heavy data consumption beyond the 500 MB/day limit.
