Astaroam eSIM Data Plans for Montenegro

Astaroam does not provide a truly unlimited data eSIM for Montenegro. All plans that carry the “Unlimited” name give a 3GB/day data allowance, after which the speed is reduced to 1000kbps. Travelers who need higher high‑speed data volumes can choose fixed‑data options, for example the 20GB 30Days plan (20GB, 30 days, $8.94 USD) or the 10GB 30Days plan (10GB, 30 days, $6.37 USD). These plans offer the full data allowance without throttling.

Astaroam does not provide a Montenegro eSIM that includes a phone number or SMS service. The available plans are data‑only, so travelers who need to receive or make calls via a local number will need to rely on VoIP applications. Applications such as WhatsApp, Telegram, and iMessage can usually be used over the data connection, but travelers should verify that these services are accessible in Montenegro before purchasing, as some destinations may block or restrict certain apps or VoIP services.

Astaroam lists a total of 28 data plans that include coverage of Montenegro, comprising 10 single‑country plans and 18 multi‑country plans. The available options span prices from $2.06 to $48.54 and data caps ranging from 500 MB up to 20 GB, with validity periods between three and thirty days. The catalog features both fixed‑data‑cap plans and daily‑data‑cap plans, allowing travellers to choose a structure that best matches their usage patterns.
