AloOui eSIM Data Plans for Montenegro

AloOui does not provide a truly unlimited high‑speed eSIM plan for Montenegro. Its plans that use the word “Unlimited” actually provide a fixed amount of high‑speed data—typically 1 GB/day or 2 GB/day—after which the connection is throttled to 512 kbps or 2000 kbps, respectively. For example, the Montenegro eSIM Unlimited Lite gives 1 GB of 5G data for a 1‑day validity and then reduces the speed once the threshold is reached; the Montenegro eSIM Unlimited Plus offers 2 GB of 5G data for a 1‑day validity before throttling.

If you need more data without speed reductions, AloOui offers fixed‑data plans such as the Montenegro 50GB for 30 days at $63.54 USD or the Balkans 100GB for 180 days at $372.50 USD. These fixed plans can be more cost‑effective for heavy data users compared to the capped unlimited plans.

AloOui does not provide Montenegro eSIM plans that include a phone number or SMS capability. Travelers can purchase only data‑only eSIMs from this provider in Montenegro. VoIP applications such as WhatsApp, Telegram, and iMessage can generally be used over the data connection for calls and messaging, but users should confirm that these services are accessible in Montenegro before purchasing.

AloOui offers 28 single‑country plans that cover only Montenegro and 60 multi‑country plans that include Montenegro as part of a broader bundle. Within these options, some plans provide a fixed data allowance—ranging from 1 GB up to 100 GB—while others use a daily data cap that resets each day. The available price range runs approximately from $6.45 to $448.42, matching the data cap spectrum of 1 GB through 100 GB.
