Numero eSIM does not provide a Yemen eSIM with a phone number or SMS capability. The provider offers only data‑only eSIM plans for Yemen, so travelers cannot receive or make standard telephone calls or send SMS messages directly through the SIM.
For voice and messaging, users can rely on popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations impose restrictions on these services, so travelers should confirm that the apps they need are accessible in Yemen before purchasing a plan.
