Astaroam eSIM Data Plans for Montenegro

Astaroam does not provide an unlimited data eSIM plan for Montenegro. The available plans for Montenegro have fixed data caps: 20 GB, 10 GB, and 5 GB, all valid for 30 days on 5G networks. Travelers who need more data may consider purchasing a plan with a larger allowance, such as the 20 GB option, which can be more cost‑effective than repeatedly buying smaller plans for heavy usage.

Astaroam does not offer an eSIM for Montenegro that includes a local phone number or SMS capability. The provider only supplies data‑only eSIMs for the country. Travelers who need to place calls or send messages can use internet‑based services such as WhatsApp, Telegram, or iMessage, which work over a data connection without requiring a phone number or SMS.

Astaroam offers six single‑country plans that cover Montenegro and a further six multi‑country plans that include the country, giving travelers a total of twelve options. The available plans range in price from roughly $3.80 to $87.03, with data caps between 1 GB and 20 GB and validity periods of 7 to 30 days. Each plan provides a fixed amount of data; several of the plans allow tethering, enabling the use of the data on connected devices.
