Nomad does not provide a truly unlimited data eSIM for Montenegro. The plans that carry “unlimited” in their name actually give 2GB of high‑speed data per day and, once that daily quota is reached, the speed drops to 1000kbps. For travelers who need more data without the daily cap, Nomad offers fixed data plans such as the 20GB 30‑day plan and the 50GB 30‑day plan, both of which provide a larger, single data allowance and can be more cost‑effective unless the user is an extremely heavy data consumer.
