Giga.Tel does not offer a local phone number or SMS capability for its Philippine eSIM plans. All available plans are data‑only, so travelers cannot place or receive traditional voice calls or text messages with a local number.
Without a local number, users can still communicate using VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations, including the Philippines, may block or restrict access to certain VoIP services, so travelers should verify that the apps they rely on work in the specific areas they intend to visit before purchasing a Giga.Tel eSIM.
