GigSky does not offer eSIM plans with a local phone number or SMS capability for Tanzania. Travelers who rely on a traditional phone number or SMS will need to use alternative methods such as a data-only plan combined with VoIP services.
GigSky's Tanzania eSIMs provide only high‑speed cellular data. Popular VoIP applications like WhatsApp, Telegram, or iMessage can be used over the data connection for calls and messaging, though some destinations may block or restrict certain apps. Travelers should confirm that the services they need are accessible in Tanzania before purchasing a plan.
