GigSky does not provide an eSIM for Niger that includes a phone number or SMS capability. Travelers can only purchase data‑only eSIM plans, which offer internet access but no built‑in voice or text services. For voice and messaging, users can rely on VoIP applications such as WhatsApp, Telegram, or iMessage when connected to the data network; however, some destinations may block or restrict certain apps, so it is advisable to confirm that the services you need work in Niger before buying a plan.
