4S eSIM eSIM Data Plans for Montenegro

4S eSIM does not provide a plan that truly delivers unlimited high‑speed data in Montenegro. All of the plans listed under the name “Unlimited” actually include a fixed data allowance—ranging from 3GB to 50GB—and once the cap is reached the speed is automatically throttled to 1000kbps.

Travelers who need large amounts of data can choose one of the fixed‑data plans instead. For example, the 50GB plan for 5 days costs about $31.14 USD, while a 20GB plan for 15 days is available for roughly $26.89 USD. Selecting a fixed‑data option can be more cost‑effective for heavy users, and the high‑speed data is unrestricted until the specified quota is used.

4S eSIM does not offer a Montenegro eSIM with a phone number or SMS capability. The provider supplies only data‑only eSIM plans for Montenegro. Travelers can still use data‑based VoIP and messaging services such as WhatsApp, Telegram, and iMessage to make calls and send messages over the internet connection.

4S eSIM provides 54 single‑country plans that cover Montenegro and 108 multi‑country plans that include Montenegro. The single‑country plans offer data from 714 MB up to 50 GB, with prices ranging from about $1.60 to $195.83 and validity periods between 1 and 365 days. Many of the plans are fixed‑data‑cap options, while others are structured around a daily data cap. The price for these plans generally starts around $1.60 for the smallest data bundle and rises toward $195.83 for the largest 50 GB option.
