Skyalo does not offer any eSIM plans for Guatemala that include a phone number or SMS capability. Travelers can only purchase a data‑only eSIM from Skyalo for this destination. However, they can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for voice calls and messaging. Some destinations, including Guatemala, may block or restrict certain VoIP services, so travelers should confirm that the apps they rely on are accessible before buying a plan.
