TailSim eSIM Data Plans for Montenegro

TailSim does not provide a truly unlimited data eSIM for Montenegro. All of its plans for the country use fixed data allowances, such as 3GB per day on the “Unlimited”‑named packages, which fall to a throttled speed of 1000 kbps after the cap. Travelers who need more high‑speed data can choose from TailSim’s fixed data plans, such as the 20 GB plan for 30 days or the 10 GB plan for 30 days, which offer larger bundles of data at a set validity period. These fixed plans can be more cost‑effective for most users unless they require a very large, uninterrupted data supply.

TailSim does not provide an eSIM for Montenegro that includes a phone number or SMS capability. The provider offers only data‑only plans for that destination. Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these services are accessible in Montenegro before purchasing.

TailSim offers 13 single‑country data plans for Montenegro and no multi‑country coverage options. The available plans span a price range from about $3.99 to $82.50, a data volume range from 1 GB to 20 GB, and validity periods from 3 to 30 days. Among the 13 single‑country choices, eight provide a daily data capping option and five offer a fixed data amount, allowing travelers to select the model that best fits their usage pattern.
