gosimless does not offer an eSIM plan for Montenegro that includes a local phone number or SMS capability. The provider’s Montenegro offerings are limited to data‑only plans, so travelers will not receive inbound or outbound voice or text services.
If communication is needed while in Montenegro, passengers can rely on VoIP applications such as WhatsApp, Telegram, or iMessage via the data connection, though some destinations may restrict access to these apps. Travelers are advised to confirm that the services they depend on are available before buying a data‑only eSIM.
