Simbye does not provide a Zambia eSIM that includes a local phone number or SMS capability. Travelers who purchase a Simbye eSIM for Zambia will receive only a data‑only plan. They can still make calls and send messages using VoIP applications such as WhatsApp, Telegram, or iMessage, provided those services are accessible in Zambia; however, destination‑specific restrictions may apply, so users should verify app availability before buying.
