Manet Travel does not provide eSIM plans for Mongolia that include a phone number or SMS capability. Travellers who need voice or text services will need to rely on data‑only plans and can use VoIP apps such as WhatsApp, Telegram, or iMessage over the data network. However, some destinations may block or restrict access to specific apps or VoIP services, so it is advisable to check that the services you rely on work in Mongolia before purchasing a plan.
