Self-sufficient phone is a system that has been implemented since May 2012, and was introduced to improve the distribution structure centered on telecommunication companies to guarantee users’ choice and reduce the price burden.
It is a system to reduce household communication costs like budget phones, but there is a difference that self-sufficiency phones aim to lower the price burden of mobile phone devices, and budget phones aim to lower communication costs.
Self-supplemented phones have the advantage of being able to choose a cell phone only by one’s own subjectivity, and the carrier and rate plan can be selected and used without being coerced by others. 자급제폰 개통방법
