5G网络再次被确认，到底是换手机还是换SIM卡？望大家相互转告！
5G的时代已经来到了，虽然现在4G的网络小编感觉已经完全足够使用了，但是随着科技发展5G网络的铺设也有它的必要性，譬如未来的许多高科技产品中像是无人VR应用，灯杆井盖的烟雾传感器，移动终端的实时监控会使用到5G的网络，而目前为了第一时间占领这片新的资源高地，现在几乎所有的运营商都宣布了5G网络的试点列表。也预计将在2019年上半年实施网络的全面铺设。但是不少网友都在担心现在的5G网到来的这么快，我们该换新手机吗，能带的起来5G网的话是不是换sim卡就好了？不过跟着小编看完后，相信大家就可以放心了。
我们先来聊一聊5G网是什么吧，在重庆首次连接5G网之后。现场第一时间做了网速测试，结果显示5G网速超过10Gbps，延迟几乎为零。和4G网相比快了不止一个量级，就靠这个速度，之后不光是秒下游戏秒下电影，未来的游戏也许会靠着网速在同一时间给我们传递更多的数据，但是就像是2G到３Ｇ的时间耗费了相当２年，小编估计5G基站的建设完成时候，因该也要三年后了，所以单单从现在的时间点上面来讲，现在还不到用考虑更换手机的时候呢。
接下来就是很多人关心的问题了，也就是我们到时候是否要换SIM卡？还是手机也得换了，毕竟因为当年在２G改换到3G 4G时，各大营业厅都有通知我们更换新的SIM卡，但是当时其实更换ｓｉｍ卡的原因倒不是３４Ｇ网络的问题，而是因为因为早期的SIM卡用户信息非常不安全，设计上很容易被复制，所以运营商利用这个机会将用户使用的SIM卡更新为更安全的USIM卡。既然现在的ｕｓｉｍ卡的安全性能有充足的保障，那么5G时代到来也没有更换SIM卡的需要。
但是手机却是需要更换成根据5G网络开发的新机型了，毕竟网速太快，5G网络会给手机全新的技术标准，如果要使用5G网络就必须换新机，因为就算是苹果华为的硬件方，使用最好的处理器的旗舰款4G手机也达不到5G手机的要求，即使你办理的是５Ｇ卡。 4G手机也开启不了５Ｇ模式，这不是刷个机换个系统版本就能解决的问题的。所以如果你想第一个吃螃蟹的话，那么可以不换ｓｉｍ只换手机哦。是不是看完了全篇对５Ｇ时代和要求有了清楚的了解了呢。
