Gaza Online does not provide a truly unlimited high‑speed data eSIM for Montenegro. All of the plans that carry the word “Unlimited” are actually limited to 1 GB of data, either per day or total, and once that limit is reached the connection is throttled to 512 kbps.
A variety of fixed‑data plans are available instead. For example, a 20 GB plan valid for 30 days costs $147.50 USD, a 10 GB plan for 30 days is $82.50 USD, and a 5 GB plan for 30 days is $45.50 USD. These options give you a larger high‑speed data allowance without the speed reduction that applies to the so‑called unlimited plans, and they are often more cost effective unless you need more data than the fixed caps allow.
