TailSim eSIM Data Plans for Montenegro

TailSim does not provide a true unlimited‑data eSIM for Montenegro, as none of its plans list a data cap of unlimited. The plans that use the word “Unlimited” in their names all include a fixed allowance of 3GB per day; once that amount is reached the speed is throttled to 1000 kbps. TailSim offers a range of fixed data plans instead, such as 20 GB for 30 days ($24.99 USD), 10 GB for 30 days ($12.99 USD) and 5 GB for 30 days ($10.99 USD). These bundles can be more cost‑effective for most travelers, while a Pay‑as‑you‑go option is not available for Montenegro.

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.
