JamboSim eSIM Data Plans for Montenegro

JamboSim does not provide a true unlimited‑data eSIM for Montenegro.
All plans that carry the word “Unlimited” give a fixed quota of 3 GB per day; once that amount is reached the connection speed falls to 1000 kbps.

If a traveler needs larger data allowances without speed throttling, JamboSim offers fixed data plans such as 50 GB for 30 days or 100 GB for 180 days, which are available for Montenegro. These high‑volume packages can be more cost‑effective for users who need a lot of data.

JamboSim provides Montenegro eSIM plans that come with a phone number and the ability to send SMS. The available plans range from 1GB for 7 days at $11.99 USD up to 20GB for 365 days at $101.99 USD. Each plan uses a US/Canada dialing code +1. Calls can be made but not received, and SMS can be sent but not received. For any specific local number or inbound messaging needs, please confirm directly with JamboSim.

JamboSim lists 10 single‑country plans that cover Montenegro and 34 multi‑country plans that include Montenegro. The single‑country options are primarily daily data‑cap plans that reset each day, making them suitable for short visits, while the multi‑country plans are fixed data‑cap packages that provide a set amount of data for the entire validity period. Prices across these plans range from $1.99 to $185.99 and data caps span from 200 MB up to 100 GB.
