ChillaxSIM eSIM Data Plans for Montenegro

ChillaxSIM does not provide a truly unlimited high‑speed data eSIM for Montenegro. The plans named “Unlimited” only offer 1GB per day of high‑speed data; after that limit is reached the speed is throttled to 5000kbps. Travelers who need more data without throttling can choose one of the fixed‑data packages, such as the 10GB plan for 5 days, the 10GB plan for 10 days, or the 50GB plan for 30 days, which provide larger data allowances before any speed reduction applies. These fixed options may be more cost‑effective for users with heavier data needs.

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.
