Wiiline does not provide eSIM plans for Zambia that include a phone number or SMS capability. Travelers can only purchase data‑only eSIMs through Wiiline for the country. However, the data connection allows the use of popular VoIP applications such as WhatsApp, Telegram, and iMessage for voice and text communication. Some destinations may restrict or block particular VoIP services, so travelers should verify that the apps they rely on will work in Zambia before buying an eSIM.
