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 11 single‑country data plans that cover only Montenegro and, in addition, 21 multi‑country plans that include Montenegro along with other destinations, bringing the total number of relevant plans to 32. The plans vary in price from about $4.01 to $105.13 and in data allowance from 1 GB up to 50 GB. Some of the offerings are fixed‑data‑cap plans, which deliver a set amount of data for the life of the subscription, while others are daily‑data‑cap plans, allowing a specified amount of data to be used each day. This mix gives travelers a range of options in both cost and data flexibility.
