BNESIM does not provide a truly unlimited data eSIM for Montenegro. The only plan with “Unlimited” in its name is the Montenegro, Republic of Unlimited 10 days plan, which offers a 3 GB/day allowance at full speed and then reduces speed to 1 Mbps after the daily limit is reached; the data amount is therefore capped.
Travelers who want a high‑volume fixed data option can choose plans such as Surf 100 GB in Montenegro, Republic of for 30 days, which provides 100 GB of high‑speed data valid for 30 days, or Surf 100 GB in Montenegro, Republic of with no expiry, which offers the same 100 GB allowance for an unlimited period. These fixed‑data plans can be more cost‑effective unless a user requires unlimited high‑speed usage.
