[2] Unitel sells its services via a network of shops; recharging cards for pre-paid contracts are also sold by individual street sellers all over Angola.

Unitel operates a network based on GSM and UMTS standards, and provides voice communications, text (SMS) and multimedia (MMS) messages, and mobile internet access.

Since December 2011, Unitel covers all Angolan municipalities, by installing a transmitter in Rivungo, Kuando Kubango province; a station which is operated by solar power.

The company was previously owned by Oi and Helios (through Africatel), Angolan state-owned oil company Sonangol and local firms like Geni holding (through Mercury), and Vidatel owned by Isabel dos Santos, each holding 25% of Unitel.

In October 2022, Angolan President João Lourenço issued a decision finalising the nationalising of Unitel, ending the links of Isabel dos Santos, the daughter of Angolan longtime ex-president, with the operator.
