Halo eSIM eSIM Data Plans for Montenegro

Halo eSIM does not provide a true unlimited data plan for Montenegro. The only options that are marketed as “Unlimited” give travelers a fixed daily allowance of 3 GB; after that daily limit the speed is throttled to 1 Mbps for the remainder of the day.

If an unlimited data experience is required, travelers can choose a fixed data plan instead. For example, Halo eSIM offers a 20 GB/30‑days plan or a 10 GB/30‑days plan for Montenegro, which provide larger, uninterrupted data allowances during the validity period.

Halo eSIM does not provide a phone number or SMS capability for Montenegro; only data‑only eSIM plans are available from this provider. Travelers who need voice or text services can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these apps are accessible in Montenegro before purchasing, as some destinations may block or restrict certain services.

Halo eSIM offers 12 single‑country plans and 9 multi‑country plans for Montenegro. The available plans range from about $4.62 to $87.39 USD and provide between 1 GB and 20 GB of data. Some of the plans feature a daily data cap, while others offer a fixed total data amount.
