Superalink does not provide eSIM plans for Tanzania that include a phone number or SMS capability. All available Superalink eSIMs for Tanzania are data‑only, meaning you can connect to 4G or 5G networks for internet access but cannot receive or make conventional voice calls or send SMS messages.
Travelers who need to communicate while in Tanzania can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, these services may be subject to local restrictions, so it is advisable to verify that the specific apps you rely on are accessible in Tanzania before purchasing a Superalink eSIM.
