如果(guo)企業(ye)在(zai)運營(ying)商(shang)辦理(li)，需要去線下營(ying)業(ye)廳，而且號碼是需要收費的(de)(de)，質(zhi)量不同，價格也不一樣，一般從幾(ji)十(shi)到(dao)幾(ji)千(qian)不等，對于很多初創企業(ye)而言，這樣辦理(li)成本(ben)是很高的(de)(de)。如果(guo)企業(ye)在(zai)服務提(ti)供商(shang)處理(li)，他們只需要在(zai)互聯網上找到(dao)一個(ge)可靠的(de)(de)，你可以選擇每(mei)個(ge)數字段的(de)(de)三(san)個(ge)運營(ying)商(shang)的(de)(de)數量，這是非常方便的(de)(de)。

在成本方(fang)面(mian)，企業只需要預存(cun)電話費(fei)，號碼(ma)是免(mian)費(fei)選擇(ze)的，預存(cun)款的金額與所選擇(ze)的包裝價格有(you)關(guan)。

但是，需要注意的是，套餐(can)價格越(yue)(yue)高，預存電話費就越(yue)(yue)多，相(xiang)應數量(liang)的質量(liang)就越(yue)(yue)好。

為了避免電(dian)話費(fei)的浪費(fei)，企業可以根(gen)據(ju)實際(ji)情(qing)況選(xuan)擇(ze)自己的套(tao)餐，并選(xuan)擇(ze)相對容易(yi)記住的號碼。

因(yin)此，我們可(ke)以看到，400電(dian)話可(ke)以免費(fei)處理，這可(ke)以很容易地在服務提供商處完成。
