ViaConecta does not offer any eSIM plans for Zambia that include a local phone number or SMS capability. The provider only sells data‑only eSIMs for this destination, so travelers will not obtain an inbound or outbound voice number through the plan.
Even without a phone number, travelers can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging. However, some destinations may restrict access to certain apps or VoIP services, so it is advisable to confirm that the apps you rely on work in Zambia before purchasing an eSIM.
