VeloeSIM does not provide an unlimited data eSIM plan for Mongolia. All of its available plans in this destination have a fixed data cap. For example, VeloeSIM offers a 10GB plan for 30 days at $54.99 USD and a 5GB plan for 30 days at $29.99 USD, each of which grants access to Mongolian cellular networks. Selecting a fixed‑data plan may be more cost‑effective for most travelers unless very heavy data use is anticipated.
