The National Telecommunications Regulatory Authority (NTRA) was out on Sunday with its monthly quality of service (QoS) report (pdf) on Egypt’s four mobile networks. Orange Egypt and Etisalat Misr fell back on the quality of their data services, while Vodafone Egypt and state-owned WE saw the highest prevalence of failed calls, according to a summary of key results courtesy of Hapi Journal. The QoS report was only recently introduced by the NTRA.
