Firsty eSIM Data Plans for Montenegro

Firsty does offer an unlimited data eSIM plan for Montenegro. The plan, called Firsty Free, has a validity of 1 day, is priced at $0 USD, and includes advertisements. It offers unlimited data but the maximum achieved speed is 256 kbps, and the service may throttle speeds. As with most unlimited plans, a fair‑usage policy applies, meaning that after heavy usage speeds may be reduced. Users who need to confirm the specific speed limits or the amount of data available at normal speed should contact Firsty directly.

Firsty does not offer Montenegro eSIM plans that include a phone number or SMS capability. All available plans from this provider for Montenegro are strictly data‑only, so you will not receive a local number or the ability to send or receive cellular text messages.

Travelers who need communication while abroad can still use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection provided by the eSIM for voice calls and messaging.

Firsty provides 16 single‑country data plans and 1 multi‑country plan that include Montenegro. The single‑country offerings span prices from free up to about $175 and data limits ranging from 1.5 GB to unlimited. Among those plans, some use a fixed data amount (e.g., a set number of gigabytes for the entire validity period), while others impose a daily data cap that refreshes each day, giving customers the option to choose between a larger all‑in‑one data allocation and a steadier daily allowance. Overall, the available plans cover a broad range of price and data cap levels, accommodating both budget travelers and those who need more substantial data use.
