JamboSim eSIM Data Plans for Montenegro

JamboSim does not offer truly unlimited high‑speed data plans for Montenegro. The plans labeled “Unlimited” actually provide 3 GB of high‑speed data each day, and once that daily limit is reached the speed is reduced to 1000 kbps. Travelers who require more data can choose from fixed‑data options, such as the 100 GB plan valid for 180 days or the 50 GB plans valid for 30 or 90 days. Fixed plans can be more cost‑effective unless the user is an extremely heavy data consumer.

JamboSim does not provide an eSIM with a local phone number or outbound SMS capability for Montenegro. All of its plans for the country are data‑only; they give you high‑speed internet but no local dialing code, voice calls or SMS services. Travelers who need to make calls or send messages can rely on popular VoIP applications such as WhatsApp, Telegram and iMessage, which operate over the data connection and do not require a local phone number.

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.
