Giga.Tel does not provide a Zambia eSIM that includes a phone number or SMS capability. The plans available from Giga.Tel in Zambia are data‑only, so travelers cannot receive or make traditional voice calls or text messages. However, the data connection can be used with internet‑based services such as WhatsApp, Telegram, or iMessage for voice and messaging. Travelers should verify that these VoIP applications are accessible in Zambia before purchasing, as some destinations may block or restrict certain apps or VoIP services.
