No, eSIM2Me does not provide an unlimited data eSIM for Montenegro. The provider offers fixed data plans instead, such as the Global Orange 100GB plan that is valid for 30 days, or the Europe & Balkans 50GB plans that are available with 3, 5, 7 or 10‑day validity periods. For travelers who need a large amount of data but do not require an unlimited supply, these fixed data plans can be a more cost‑effective choice unless the user is an extremely heavy data consumer.
