RedSim does not provide a truly unlimited high‑speed data eSIM for Montenegro. All Montenegro‑specific plans list a daily cap—3 GB per day for the Montenegro Unlimited plans or 5 GB per day for the Europe (41 countries) Unlimited plans that include Montenegro. When the daily limit is reached, speed drops to 1 Mbps (or 384 kbps for the 10GB/day 1‑day plan) for the remainder of the day, so the data allowance is not unlimited.
Travelers who need a larger data allowance can choose fixed‑data plans such as the 20 GB 30‑day plan, which gives 20 GB of high‑speed data to use within that period, or the 10 GB/day 1‑day plan, which offers 10 GB of high‑speed data for a single day before throttling. These fixed‑data options may be more cost‑effective for most travelers than the daily‑cap “Unlimited” plans.
