Astaroam eSIM Data Plans for Montenegro

Astaroam does not provide a truly unlimited high‑speed data plan for Montenegro. Their “Unlimited” options give 3 GB per day and throttle speed to 1000 kbps once the daily limit is reached. Travelers can instead choose from fixed‑data plans such as the 20 GB 30‑day plan at $9.01, the 10 GB 30‑day plan at $6.42, or the 5 GB 30‑day plan at $4.58. Those fixed‑data plans are usually more cost effective unless a user anticipates extremely heavy data usage.

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 provides 10 single‑country eSIM plans that cover Montenegro and an additional 6 multi‑country plans that include Montenegro in their coverage. The plans range in price from about US $2.08 to US $48.92, while the data limits offered span from 1 GB up to 20 GB. For customers looking for a predictable data allowance Astaroam supplies 13 fixed data‑cap plans, whereas 3 of the plans reset their data on a daily basis. The validity of the plans varies between 3 and 30 days, giving users flexibility in how long they want to stay connected while traveling.
