Giga.Tel does not provide any Guatemala eSIM plan that includes a local phone number or SMS capability. Only data‑only eSIM options are offered for travelers visiting Guatemala with this provider.
For voice and messaging, travelers can use VoIP services such as WhatsApp, Telegram, or iMessage over the data connection. These apps typically function without a local phone number, but availability can vary in certain markets, so it is advisable to confirm that the apps you need are accessible in Guatemala before purchasing a Giga.Tel plan.
