yaySIM does not offer an Egypt eSIM that includes a phone number or SMS capability. The provider only supplies data‑only plans for the country, so travelers will not receive a local number or receive text messages with the eSIM.
Without a phone number, callers can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection to make voice or video calls and send messages. However, some destinations may block or restrict access to specific apps or VoIP services, so users should confirm that the services they rely on are available in Egypt before purchasing a plan.
