GigSky does not provide an eSIM plan for Argentina that includes a phone number or SMS capability. Travelers who need a local phone number or SMS must look for a different provider or rely on data‑only plans and use VoIP applications such as WhatsApp, Telegram, or iMessage to make calls and send messages. Keep in mind that some destinations may block or restrict certain VoIP services, so it is advisable to confirm that the apps you plan to use are accessible in Argentina before purchasing a GigSky plan.
