VoidMob does not provide an Oman eSIM that comes with a local phone number or SMS capability; all eSIM plans sold by VoidMob for Oman are data‑only. If a traveler needs to make or receive voice calls using a traditional phone number, this option is not available from VoidMob for Oman.
Over the data connection, VoIP applications such as WhatsApp, Telegram, or iMessage can be used to send messages and make calls, but travelers should check whether these services are accessible in Oman before purchasing, as some destinations may block or restrict certain apps.
