thirr.com eSIM Data Plans for Montenegro

thirr.com does not provide any unlimited data eSIM plans for Montenegro.

Instead, thirr.com offers several fixed‑data options. For example, the EU BASE 100GB 30D plan supplies 100 GB of data for 30 days, while the Mediteran 100GB 30D plan also offers 100 GB for 30 days. A smaller option, EU BASE 50GB 30D, gives 50 GB for 30 days. These plans are examples of the fixed‑data choices available; they represent only a portion of the full selection. Choosing a fixed plan may be more cost‑effective unless you anticipate very heavy data usage.

thirr.com does not offer a Montenegro eSIM plan that includes a local phone number or SMS capability. Only data‑only eSIMs are available from thirr.com for Montenegro; travelers can rely on data‑based VoIP applications such as WhatsApp, Telegram, or iMessage for calls and messaging. However, some destinations may block or limit access to specific apps or VoIP services, so travelers should confirm that the apps they need are usable in Montenegro before buying a plan.

thirr.com lists 7 single‑country plans and 42 multi‑country plans covering Montenegro, with prices ranging from roughly $2.28 to $343.24 and data caps between 1 GB and 100 GB; validity periods vary from 3 to 365 days, and most plans allow tethering, while data caps are typically fixed amounts rather than daily limits.
