SimOptions does not provide any Tanzania eSIM plan that includes a phone number or SMS capability. Only data‑only eSIMs are offered for Tanzania. Travelers who need voice or text communications can use VoIP services such as WhatsApp, Telegram, or iMessage over the data connection, but the availability of these apps can vary and may be restricted in some regions. It is advisable to confirm that the specific VoIP applications you rely on are accessible in Tanzania before purchasing an eSIM.
