5G时代需要更换手机和手机卡吗？中国移动给出答案
5G的推行已经迫在眉睫，各大运营商都给出了时间表，而5G的推行也不是运营商单方面的事情，毕竟运营商的服务只是从基站到手机卡，而手机卡要装到手机上才能用，那么5G时代，我们需要更换手机和手机卡吗？
其实有很多人对所谓的4G、5G的概念不太了解，我们举个例子，就好比家里用的水管和水龙头，我们要想家里的水龙头流水更快一些，应该怎么办呢？
首先要从源头开始，必须要有自来水公司提供足够大的水压，这就相当于运营商的基站，没有这个就没有水，也就没有信号。
其次，只有一定的水压，而没有管道来输送水也是不行的，我们还要有足够粗的水管来保证水流速度，类比到运营商就相当于要提供更好的信号频率。
最后，水管到我们用户家里之后我们要有一个水龙头吧，这样我们就可以随时开关控制水流。同样水龙头的大小也会影响我们流水的速度，这就相当于我们使用的手机终端，可以随时接收信号和上网。
这么一类比就不难理解了，5G相对4G来说就相当于把压力、水管和水龙头都进行了升级，任何一个环节不匹配的换都是不能满足用户对5G的需求。
运营商们建立基站，增强网络信号，都是在做这方面的准备，而据了解，由于5G采取了全新的网络制式和网络频率，世界上还没有任何一部手机可以支持5G信号，也就是说如果用户想要体验5G服务，到时候必须要更换手机。
关于是否要更换SIM卡的问题，中国移动给出答案，未来4G的手机卡在5G手机上可以兼容并正常使用，因为手机卡只是相当于一个标签存在，并不提供接收信号的功能，因此未来我们没有必要更换手机卡。不过根据3G到4G时代的经验，通常更换手机卡是运营商们免费提供的，这一点我们不必担心。
综上所述，如果要享受5G的体验，是需要更换手机，而没有必要更换手机卡的，相信大家都可以理解了。5G时代的高网速、低延时已经让很多人非常向往了，到时候，我们会进入一个全新的更快速的时代，相信5G可以让我们的信息沟通更加的流畅。
