esimzon does not provide an Oman eSIM that includes a phone number or SMS capability. The available plans are data‑only, so travelers will not receive a local number for making outbound or inbound calls, nor will they receive SMS messages. Travelers who need voice or messaging can rely on VoIP services such as WhatsApp, Telegram, or iMessage over the data connection. However, it is advisable to confirm that these applications are accessible and not restricted in Oman before purchasing a plan.
