GigSky does not provide a phone number or SMS service for its Nigerian eSIM plans. Customers can only purchase data‑only plans for use over the local network.
Travelers who rely on voice and text may still use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations restrict certain apps or VoIP services, so users should verify that the apps they need are accessible in Nigeria before buying a plan.
