Instabridge does not provide a Mongolia eSIM plan that includes a phone number or SMS capability. All eSIMs offered by Instabridge for Mongolia are data‑only plans, so travelers can use internet data but cannot receive or make voice calls or SMS through the local network.
Travelers who need messaging or calling can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict access to specific apps or VoIP services, so it is advisable to verify that the apps you depend on are available in Mongolia before purchasing an eSIM.
