GulfData does not provide a truly unlimited data eSIM for Montenegro. The plans that use “Unlimited” in the name actually allow 1 GB per day at full speed, after which the connection is throttled to 512 kbps. Because of this fixed daily cap they are not considered unlimited plans in the eSIM industry.
Instead, GulfData offers fixed data plans that can be more cost‑effective for most travelers. For example, the Montenegro 20GB – 30 days plan gives 20 GB of high‑speed data that must be used within 30 days, and it has no speed reduction. Other options include the Balkans 20GB – 30 days plan and the Global 20GB – 90 days plans, all of which provide a hard data allowance with no throttling once the data is exhausted.
