Instabridge does not offer an Oman eSIM that includes a local phone number or SMS capability. Travelers using Instabridge in Oman will receive a data‑only eSIM, and they can rely on VoIP applications such as WhatsApp, Telegram, and iMessage for voice and text communication. However, some destinations may block or restrict certain VoIP services, so it is advisable to confirm that the apps a traveler needs are accessible in Oman before purchasing.
