JamboSim eSIM Data Plans for Montenegro

JamboSim does not provide a true unlimited‑data eSIM for Montenegro. All of the plans marketed with “Unlimited” in the name offer a fixed amount of high‑speed data – 3GB per day – and after that cap is reached the speed is throttled to 1000kbps. For travelers who need more data, F‑JamboSim offers fixed‑amount plans, such as 50GB for 30 days or 100GB for 180 days, which may be more cost‑effective for heavy usage.

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 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.
