Roambit does not offer an eSIM plan that provides a local phone number or SMS capability for Zambia. Travelers who purchase a Roambit eSIM will receive only a data‑only plan, which lets them browse the Internet, use VoIP applications, and access streaming services.
With a data‑only eSIM, users can still make voice and text communications through popular VoIP apps such as WhatsApp, Telegram, and iMessage, provided those services are not blocked in Zambia. Because access to some applications can change, it is advisable for travelers to verify that the VoIP services they rely on are available in Zambia before purchasing an eSIM.
