eSIM4Travel does not offer any Oman eSIM plans that include a phone number or SMS capability. The available plans are data‑only and provide high‑speed internet access for the validity period specified.
Travelers who need communication can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. Since some destinations may block or limit certain apps or services, users should verify that the VoIP services they rely on are accessible in Oman before buying a plan.
