The Paraguayan Congress has requested a review by telecoms regulator Conatel on the resolution that authorized the merger of Telefonica Celular del Paraguay (Telecel) and Compania Privada de Comunicaciones (CPC), Portal Paraguayo de Noticias reports. Telecel operates on the local market under the Tigo brand name.

Back in 2011 Conatel had approved the merger between the two companies, which also granted the use of the 900 MHz frequency band by Tigo. According to the initiative started by congresswoman Olga Ferreira de Lopez, Tigo was thus allowed to provide 4G mobile broadband services to the detriment of state-owned company Copaco.

Conatel will have to provide details on the procedure via which it gave the green light to the two operators’ merger, as well as make public the reason why the CPC maintained a valid licence for use of the 900 MHz spectrum, since the authorization was granted in 1997 but the spectrum had never been used until the merger.
