JamboSim eSIM Data Plans for Montenegro

JamboSim does not provide a truly unlimited data eSIM for Montenegro.
The plans that carry the word “Unlimited” in their name give 3GB of high‑speed data each day; after that limit is reached the speed is throttled to 1000kbps.

Travelers who need more data can opt for fixed‑data plans instead. For example, a 50GB plan that is valid for 30 days costs $75.99, and a 100GB plan for 180 days is available for $195.99. These higher‑cap options offer a predictable amount of data without the speed reduction that comes with the “Unlimited” plans.

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 supplies 10 single‑country data plans for Montenegro and 65 multi‑country plans that include Montenegro. The single‑country options range from 200 MB to 100 GB and are priced between $1.99 and $196.99. Multi‑country plans follow a similar price and data‑cap spectrum, some offering fixed data amounts while others provide daily data caps. Tethering is allowed on most plans, though speed may be reduced to 1000 kbps in certain cases.
