4S eSIM eSIM Data Plans for Montenegro

4S eSIM does not provide a truly unlimited data eSIM for Montenegro. Their “Unlimited” plans actually have a fixed high‑speed data allowance; after using their specified amount the speed is reduced to 1 000 kbps. For example, the Montenegro 3GB Unlimited plan offers 3 GB of speed before throttling, while the Montenegro 20GB Unlimited plan offers 4 GB per day over 5 days.

If a traveler needs a large amount of data, 4S eSIM offers fixed‑data alternatives. The Montenegro 50GB plan gives 50 GB of unthrottled high‑speed data for 5 days, and the Montenegro 30GB Unlimited plan gives 2 GB per day for 15 days. These are representative of the available high‑data options and are not exhaustive of all plans.

4S eSIM does not provide a phone number or SMS capability for Montenegro, so only data‑only eSIMs are available from this provider.
Travelers who need voice or text messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these services are accessible in Montenegro before purchasing a plan.

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.
