友情提示：拨打长途电话的办法很多，可以使用各通信运营商（包括中国电信、中国移动、中国联通等）固定电话、移动手机或者上网电脑来实现通话功能，固定电话、移动手机可以直接拨打对方号码也可以通过IP电话（又名VoIP电话、网络电话）拨打，上网电脑可以免费与对方上网电脑通话也可以低价拨打对方固定电话、移动手机，请根据各自情况综合考虑选用。
问题报告： 本站尽力为您提供最全面、仔细、准确的长途电话区号、手机号段归属、电话号码查询信息，但因为各个地区的合并、增加、撤销、变更以及电话号码方案变更、升位还有地名的多样性等问题，难以避免出现错误或者过时信息，非常欢迎大家在使用中报告发现的问题或者告知更新内容。请直接在下面留言，本站核实后会马上进行修改，以便对以后的浏览者有更好的帮助，非常感谢！
