JamboSim eSIM Data Plans for Montenegro

JamboSim does not offer a truly unlimited data eSIM for Montenegro. All of its plans for the country have a hard cap of 3 GB per day, after which the speed is reduced to about 1 Mbps. Travelers who need more data can choose from the fixed‑data plans listed in the dataset, such as the 3 GB/day plans that last 3, 5, 7, 10, 15, 30 days, or the larger 50 GB or 100 GB bundles that are valid for 7, 30, or 180 days. These fixed‑data options provide a clear data allowance and validity period, which can be more cost‑effective for most users compared to a plan that advertises “unlimited” but actually throttles after a daily limit.

JamboSim offers eSIM plans that include a phone number for Montenegro. All plans use the dialing code +1, allowing outbound voice calls and outbound SMS messages; inbound voice and SMS are not supported. The available plans range from 1 GB for 7 days priced at $11.99 USD to 20 GB for 365 days priced at $105.99 USD, covering validity periods of 7 to 365 days. Because the phone number comes from the +1 dialing area and has only outbound capabilities, travelers who need local inbound calling or messaging should confirm the specific functionality with JamboSim before purchase.

JamboSim lists 10 single‑country data plans that include Montenegro. The provider does not offer any multi‑country plans that cover Montenegro. The available single‑country plans range from $1.99 to $196.99 and offer data caps between 200 MB and 100 GB, giving travelers a broad spectrum of options to choose from depending on their usage needs.
