eSIM2Me does not provide a phone number or SMS support for Oman. Their Oman eSIM plans are data‑only, so travelers cannot make or receive conventional calls or texts via the local network. They can still use VoIP applications such as WhatsApp, Telegram or iMessage over the data connection, though some destinations may block or restrict access to certain apps or services, so travelers should confirm that the apps they rely on will be available in Oman before purchasing.
