Airalo does not offer any eSIM plan for Nigeria that includes a local phone number or the ability to send or receive SMS. Travelers can only purchase data‑only eSIMs for the country. These data plans allow the use of VoIP applications such as WhatsApp, Telegram, and iMessage over the internet, but some destinations may block or limit access to specific apps or services, so users should verify that the apps they rely on are available in Nigeria before purchasing.
