Ohayu eSIM Data Plans for Montenegro

Ohayu does not provide a truly unlimited data eSIM for Montenegro. The plans listed under “Montenegro Unlimited” actually allow 3 GB per day and, after that limit is reached, the speed is reduced to 1000 kbps. If a traveler's usage exceeds the 3 GB/day threshold, their data will slow down rather than remain unlimited.

Alternatively, Ohayu offers fixed‑data plans that may be more economical for frequent or heavy data users. For example, a 50 GB plan for 90 days costs $71.49 USD, and a 25 GB monthly plan costs $49.49 USD. These plans provide a higher data allowance than the unlimited‑name plans without the speed throttling that follows the daily limit.

Ohayu does not provide any Montenegro eSIM plans that include a phone number or SMS capability. Instead, all Ohayu eSIMs for Montenegro are data‑only, and travelers can use VoIP services such as WhatsApp, Telegram, or iMessage over the data connection for communication.

Ohayu provides a total of 13 distinct data plans that include coverage in Montenegro. Nine of these are single‑country plans, while four are multi‑country packages that also cover Montenegro. The available plans range in price from $8.49 to $71.49 and offer data limits between 2 GB and 50 GB, with validity periods from 5 days to 90 days. Within these options, some plans use a fixed data amount for the entire validity period, while others offer a daily data cap that allows a set amount of data each day. This variety gives travelers flexibility to choose a package that best matches their usage habits and time in Montenegro.
