GigSky does not provide a Mongolian eSIM that includes a phone number or SMS capability. For travelers who need a local phone number or the ability to send SMS messages in Mongolia, a different provider must be selected, or alternative communication methods must be used.
While GigSky offers data‑only eSIM plans that allow the use of VoIP applications such as WhatsApp, Telegram, and iMessage over the mobile data connection, some destinations may block or restrict access to these services. Travelers should verify that the VoIP apps they rely on are available in Mongolia before purchasing a plan.
