MTX Connect does not provide a Tanzania eSIM plan that includes a local phone number or SMS capability. The available plans are data‑only and allow internet access, but do not support inbound or outbound telephone calls or text messages. Travelers who need voice or messaging services can rely on VoIP applications such as WhatsApp, Telegram or iMessage, which operate over the data connection. However, some destinations may limit access to certain VoIP services, so it is advisable to verify that the apps you rely on work in Tanzania before purchasing an eSIM from MTX Connect.
