4S eSIM eSIM Data Plans for Montenegro

4S eSIM does not provide a truly unlimited data eSIM for Montenegro. All plans listed for Montenegro have a fixed data allowance, such as 3 GB, 5 GB, 10 GB, 20 GB, 30 GB, 50 GB, or larger, and each plan is tied to a specific validity period ranging from 1 day to 30 days. Travelers who need a large amount of data can choose a fixed plan with a high data cap—for example, a 50 GB plan valid for 5 days or a 30 GB plan valid for 15 days—rather than an unlimited option.

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.
