Simsima eSIM Data Plans for Montenegro

Simsima does not provide a truly unlimited data eSIM for Montenegro. The plans that carry the “Unlimited” label give a fixed allowance of 3 GB per day; after that daily amount the speed is throttled to 1000 kbps.

For travelers who need a larger data allowance, Simsima offers fixed‑data plans such as 50 GB for 30 days or 20 GB for 30 days. These plans give a substantial amount of high‑speed data before any reduction in speed occurs, making them more cost‑effective for typical usage.

Simsima does not offer a Montenegro eSIM with a phone number or SMS capability. The provider sells only data‑only eSIM plans for Montenegro, so there is no inbound or outbound voice or text service included.

Travelers who need to make calls or send messages can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection. However, these services are not guaranteed to work everywhere; some destinations block or restrict certain apps, so it is advisable to confirm that the apps you rely on are accessible in Montenegro before purchasing a plan.

Simsima provides 10 single‑country plans that cover only Montenegro, and 20 multi‑country plans that include Montenegro as part of a broader regional coverage, for a total of 30 distinct options. The plans span a price range of roughly $4.20 to $105.10 USD, with data caps from 1 GB up to 50 GB. Within these offerings, 7 plans have a daily data cap that resets each day, letting travelers use a small amount of data per day, while 23 are fixed‑data plans that deliver a set amount of data for the entire validity period, without daily limits. This mix allows users to choose between short‑term daily usage or longer‑term bulk data depending on their travel needs.
