gosimless does not provide an eSIM plan for Eswatini (Swaziland) that includes a local phone number or SMS capability. The provider offers only data‑only eSIMs in this destination, meaning users cannot make traditional voice calls or receive text messages through a local number.
Travelers can still use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for voice and messaging services. Since these services rely on data rather than a phone number or SMS, they remain available regardless of the lack of telephony support in the eswatini eSIM plan.
