Giga.Tel does not provide an Oman eSIM that includes a phone number or SMS capability; only data‑only plans are offered for this destination.
Travelers wishing to make voice or text communications while in Oman can use popular VoIP apps such as WhatsApp, Telegram, and iMessage over the data connection. However, access to these services can sometimes be limited or blocked in certain regions, so it is advisable to check that the apps you rely on are available in Oman before purchasing a Giga.Tel eSIM.
