曾与18X号段一同预留给3G的15X号段,自年初开始在各地悄悄普及。从年初到现在中国移动的新增用户很多都开始使用158和159打头的号码,据运营商解释,15X号段的应用最直接的原因就是随着用户的激增,以往的13X号段已经瓜分殆尽,趋于饱和,需要另辟“新大陆”。 Section 15X, which was reserved for 3G together with section 18X, has been quietly popularized all over the country since the beginning of the year. From the beginning of the year till now, many new subscribers of China Mobile have started to use the numbers starting with 158 and 159. According to the operators, the most direct reason for the application of No. 15X segment is that as the users surged, the old No. 13X segment was already distributed To make it saturated and to open another “new continent.”
