Этот телефон у меня с 2008 года. Работает до сих пор. Батарею еще не менял, хотя пора уже. Отличный телефон. По истечении 8 лет абоненты стали жаловаться, что плохо меня слышат. Решил проблему настойками в инженерном меню. Усилил чувствительность микрофона. use Samsung SGH-D780 Duos month or more i recommend it should buy |

Main feature:
The main advantage of the Samsung SGH-D780 Duos is that both SIM cards remain active at all times. There are many phones that use two cards, but most of them require switching from one SIM to another. Samsung Duos actually works with two numbers at once — these are real “two phones in one”. It is for this purpose that TWO transceivers are installed in it.
