Every the end of the month, I worry about the cellular phone charge. Usually on the charge paper, more much amount of money is written than I have expected. I don’t understand well why the cellular phone charge is too expensive.
Thesedays people use some kinds of communication means like internet (messenger or blog) or telephone. But only the charge of cellular phone is high. Wireless internet is mobile commucation mean,too. But its rate is not too expensive as cellular phone rate.
SK telecom, LG telecom and KTF have to make reserchs of the ways to reduce the charge. Only offering many card services (mobile carrier card) is not the way for customer satisfaction.
