ChillaxSIM eSIM Data Plans for Montenegro

ChillaxSIM does not provide any truly unlimited data eSIM for Montenegro. All plans that carry the word “Unlimited” in their name contain a limited high‑speed allowance of 1GB and specify a reduced speed of 5120kbps once the limit is reached.

Instead, ChillaxSIM offers fixed‑data options that might better suit heavier users. For instance, a 20GB plan is available for 30 days at $37.90 USD, a 30GB plan costs $54.90 USD for 30 days, and a 10GB plan can be purchased for 10 days at $18.90 USD. Each of these plans includes tethering and specifies a reduced speed of 128kbps after the high‑speed data is exhausted.

ChillaxSIM does not offer a Montenegro eSIM that includes a phone number or SMS capability. Only data‑only plans are available for Montenegro through ChillaxSIM.

Users can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for voice and messaging, which works without a local phone number or SMS service.

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.
