Voyasim does not provide an eSIM for Ethiopia that includes a phone number or SMS capability. Travelers can only purchase data‑only plans from this provider. If voice or text communication is needed, popular VoIP applications such as WhatsApp, Telegram, or iMessage can be used over the data connection, but availability of these services can vary in Ethiopia, so it is advisable to confirm that the apps you rely on are accessible before buying a plan.
