ChillaxSIM eSIM Data Plans for Montenegro

ChillaxSIM does not provide a truly unlimited data eSIM for Montenegro. The plans that contain “Unlimited” in their titles, such as the Balkans 12 Countries Unlimited Data for 1 day or 3 days, actually allot only 1 GB of high‑speed data; once the limit is reached, the connection throttles to 5000kbps.

Instead, ChillaxSIM offers fixed data plans that cover the region, including options such as 50 GB for 30 days or 30 GB for 30 days, both allowing tethering and providing 128kbps speed after the data allowance is used. These plans are available for travellers who need more than the 1 GB offered by the “Unlimited”‑named plans.

ChillaxSIM does not provide a Montenegro eSIM plan that includes a phone number or SMS capability. Only data‑only eSIMs are available from the provider for Montenegro. Travelers can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection to make calls and send messages, but the availability of these services may vary in Montenegro, so users should check that the apps they rely on work there before purchasing.

ChillaxSIM currently offers 42 data plans with coverage in Montenegro, all of which are multi-country options. These plans range in price from $3.90 to $105.90 and provide a data allowance between 1GB and 50GB. Available plans include both fixed data options (a set amount of data for the plan’s duration) and daily data cap plans, which provide a certain amount of data per day. Some plans may also have reduced speeds after a certain data usage threshold, at either 128kbps or 5120kbps.
