Horizon eSIM eSIM Data Plans for Montenegro

Horizon eSIM does not provide an unlimited‑data eSIM for Montenegro. All of Horizon eSIM’s Montenegro offerings are fixed‑data plans with a capped data allowance and a set validity period. For example, the “Montenegro 20GB 30Days” plan gives 20GB of high‑speed data usable within 30 days, and the “Montenegro 10GB 30Days” plan provides 10GB for the same period. While these bundles can be more cost‑effective for travelers who need a large amount of data but are not extreme users, they do not grant unlimited data access.

Horizon eSIM does not offer plans that include a phone number or SMS capability for Montenegro. The provider only offers data‑only eSIM plans for the country. Travelers who need voice or text service can use VoIP apps such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these services are available and unrestricted in Montenegro before purchasing.

Horizon eSIM offers nine single‑country data plans for Montenegro. These plans vary in price from about $0.31 to $309.16 and provide data caps ranging from 1 GB up to 20 GB, with validity periods between 7 and 365 days. No multi‑country plans are listed for Montenegro.
