At the National Assembly Science. ICT. Broadcasting. and Communications Committee audit, controversy erupted over delays in introducing the "integrated plan," long cited as key to cutting phone bills.
Park Jeong-hun of the People Power Party said, "Former Minister Yoo Sang-im of the Ministry of Science and ICT promised a first-quarter launch—why is it being delayed?"
The integrated plan lets subscribers choose rates based on data volume and transmission speed without distinguishing between 5G and LTE, and has been pursued following criticism of a "rate reversal" in which some LTE plans cost more than 5G.
Second Vice Minister Ryu Je-myung of the Ministry of Science and ICT said, "Plans that showed a rate reversal have largely been resolved, including through halted subscriptions, and we are reviewing ways to tie in QoS (additional data service at 1–5 Mbps after basic data is used up) improvements to provide greater benefits."
