Simsima eSIM Data Plans for Montenegro

Simsima does not provide a true unlimited‑data eSIM for Montenegro. The plans titled “Unlimited” in the catalogue offer 3 GB of high‑speed data each day; once that daily quota is reached, the connection is throttled to 1000 kbps. Consequently, the plans are technically capped rather than offering unlimited data.

For travelers who need large amounts of high‑speed data, Simsima supplies fixed‑cap options. Examples include a 100 GB plan valid for 180 days, a 50 GB plan for 30 days (or 90 days), and a 20 GB plan for 30 days. These can be more cost‑effective, especially for users whose consumption does not exceed the fixed allowances.

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 lists 10 single‑country data plans for Montenegro and 19 multi‑country plans that include the country as part of regional coverage. The plans span a price range from roughly $3.75 to $172.36, with data caps that vary between 1 GB and 100 GB and validity periods that last from 5 days up to 180 days. The offering contains both fixed‑data‑cap plans—where a set amount of data is supplied for the entire validity—and daily‑cap plans, in which the available data is limited on a day‑by‑day basis.
