Stellar eSim does not offer any eSIM plans for Tanzania that include a phone number or SMS capability. Only data‑only eSIMs are available for that destination.
Travelers can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for calls and messaging. Some destinations may block or restrict access to specific apps or VoIP services, so it is advisable to confirm that the apps you rely on are accessible in Tanzania before purchasing.
