Before purchasing a smartphone cheaply, it is necessary to first organize the concept of the single-tong method.The Dantong Act, which has been in effect since October 2014,In other words, the Terminal Distribution Structure Improvement Act focuses on regulating illegal subsidies.Despite the same terminal, it is caused by a series of incidents in which someone buys at a low price and someone buys at a high price.The important keywords here are public subsidies, optional contract discounts, and self-sufficient mobile phones! These are three things.The public subsidy is slightly different for each mobile operator, but you can see that the average calculation amount is the same.For example, if a terminal manufactured by company A costs 1 million won, and the public subsidy is 300,000 won, you can purchase the device with the difference of 700,000 won.For reference, in case of iPhone, the support is usually less than 100,000 won, which is rather low.The optional contract discount system refers to a system that provides a 25% discount on the terminal price instead of using the terminal for 12 to 24 months without receiving public subsidy at all.Doesnt it look somewhat similar to the agreement we commonly know?If the public subsidy is set higher among the public subsidy and the optional contract discount, you can choose the public subsidy.If the optional contract discount rate is higher, you can choose the optional contract discount.Whichever of the two you do, you can choose the one that is advantageous to you.The two systems cannot be overlapped.Since public announcement subsidies are calculated differently depending on the terminal and the carrier, it is recommended that you make a selection after checking through mobile phone price comparison.What to consider when choosing a mobile phone is the selection of specifications according to the purpose of use. Galaxy S20, Galaxy Note 10, Galaxy Zflip, LG Smartphone V50 to Galaxy A90, Galaxy A80, Galaxy A50 Check out the performance and purpose of your cell phone model Its good to buy it.Lastly, a self-sufficient mobile phone refers to a mobile phone purchased with a one-time payment without any support from a carrier.H store or a place like S companyYou can think of what youre buying as belonging to this category.Wouldnt it be a little bit of a benefit to the household if you buy a cell phone whose body value is the price of gold, after comparing the price?
