BetterRoaming does not provide a Zambia eSIM that includes a phone number or SMS capability. The provider offers only data‑only eSIM plans for Zambia, so travelers will not receive a local calling code or the ability to send and receive text messages through the network.
Because no telephony features are included, users typically rely on VoIP applications such as WhatsApp, Telegram, or iMessage to make calls and send messages over the data connection. These apps usually work in Zambia, but travelers should verify that the services they need are accessible in the country before purchasing a plan.
