Avelis eSIM does not provide a plan for Eswatini (Swaziland) that includes a phone number or SMS capability. Travelers can only purchase a data‑only eSIM from this provider for the destination. If voice or text communication is needed, popular VoIP applications such as WhatsApp, Telegram, and iMessage can generally be used over the data connection, but some destinations may block or restrict access to specific apps or VoIP services, so it is advisable to verify that the apps you rely on are accessible in Eswatini (Swaziland) before purchasing.
