GigSky does not provide any eSIM plans for Guatemala that include a phone number or SMS capability. The provider offers only data‑only eSIMs for this destination.
Travelers who need voice or messaging can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. Because access to these services can be blocked or restricted in some places, users should confirm that the apps they rely on are available in Guatemala before purchasing a plan.
