Giga.Tel does not provide El Salvador eSIM plans that include a phone number or SMS capability. Travelers who purchase a Giga.Tel eSIM for El Salvador will receive only a data‑only plan, so traditional voice calls and text messages cannot be sent or received via the local network.
Instead, users may rely on internet‑based VoIP services such as WhatsApp, Telegram, or iMessage, which function over the data connection, to communicate. Those services are not guaranteed to work everywhere; prospective customers should verify that the apps they need are accessible in El Salvador before buying an eSIM.
