GIGAGO does not offer an eSIM for Eswatini (Swaziland) that includes a phone number or SMS capability. Travelers can only purchase data‑only eSIM plans from this provider for the destination.
If a voice or text experience is required, the usual workaround is to use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. Because some destinations block or restrict specific apps, it is advisable to confirm that the VoIP services you intend to use are accessible in Eswatini (Swaziland) before buying a plan.
