很多(duo)人(ren)經常打(da)(da)著400免(mian)費(fei)電(dian)(dian)(dian)話(hua)(hua)(hua)(hua)(hua)的(de)幌子(zi)，所(suo)有(you)其(qi)他400電(dian)(dian)(dian)話(hua)(hua)(hua)(hua)(hua)都(dou)不是(shi)(shi)免(mian)費(fei)的(de)。400電(dian)(dian)(dian)話(hua)(hua)(hua)(hua)(hua)是(shi)(shi)全國統一的(de)號碼。在中國任何地(di)方打(da)(da)電(dian)(dian)(dian)話(hua)(hua)(hua)(hua)(hua)都(dou)像打(da)(da)當(dang)地(di)電(dian)(dian)(dian)話(hua)(hua)(hua)(hua)(hua)，沒有(you)漫游(you)。手機(ji)(ji)和飛機(ji)(ji)都(dou)可以(yi)撥打(da)(da)，是(shi)(shi)800電(dian)(dian)(dian)話(hua)(hua)(hua)(hua)(hua)的(de)升級版(ban)。800電(dian)(dian)(dian)話(hua)(hua)(hua)(hua)(hua)才是(shi)(shi)真正的(de)免(mian)費(fei)電(dian)(dian)(dian)話(hua)(hua)(hua)(hua)(hua)。但是(shi)(shi)800電(dian)(dian)(dian)話(hua)(hua)(hua)(hua)(hua)只能用座機(ji)(ji)電(dian)(dian)(dian)話(hua)(hua)(hua)(hua)(hua)，手機(ji)(ji)打(da)(da)不到。400電(dian)(dian)(dian)話(hua)(hua)(hua)(hua)(hua)比800電(dian)(dian)(dian)話(hua)(hua)(hua)(hua)(hua)便宜很多(duo)。400是(shi)(shi)雙(shuang)向分攤收費(fei)，可以(yi)避免(mian)惡意撥打(da)(da)。總的(de)來說(shuo)，400電(dian)(dian)(dian)話(hua)(hua)(hua)(hua)(hua)不錯，建議使(shi)用。

客戶更(geng)(geng)滿意，企業(ye)(ye)會更(geng)(geng)好(hao)是(shi)400電(dian)話的原因，也是(shi)服務(wu)態度，14年來，致力于為企業(ye)(ye)提供更(geng)(geng)親(qin)密、細致的服務(wu)、更(geng)(geng)好(hao)、更(geng)(geng)安全(quan)的技術、更(geng)(geng)先進、更(geng)(geng)方(fang)便的功(gong)能，開放400電(dian)話服務(wu)只是(shi)開始，長(chang)期售(shou)后服務(wu)是(shi)用戶選擇的根(gen)本原因。
