GigSky does not provide any eSIM plans that include a local phone number or SMS capability for Paraguay. Travelers wishing to maintain a phone number or send SMS messages in Paraguay must use the data-only eSIMs that GigSky offers and rely on VoIP applications such as WhatsApp, Telegram, or iMessage for voice and text communication. However, the availability of these VoIP services can vary, so travelers should check that the apps they need are accessible in Paraguay before purchasing a plan.
