5G时代到来，刚买4G手机的用户怎么办？这两点有必要了解一下！
从今年上半年开始，国内外众多手机厂商已经陆续发布5G智能手机。之前，中国移动预测，预商用阶段5G手机价格在8000元以上，规模化后可能在千元左右，可见5G手机跟4G手机相比，价格变化也不大。资费方面，5G是进入互联网高速公路的入口，到时候日常流量使用肯定要高于4G，但根据三大运营商的说法，5G的资费不会高于4G。移动更加霸气，中国移动首个5G套餐直接开出了“一毛钱1GB”的“白菜价”，即使你每个月使用1TB流量，资费也才100多元。
除了流量资费问题，群众更关心的是手机的问题，一位网友抱怨：“刚买的iPhone XS max花了1万多，可是看到5G电话卡都诞生了，心里懊恼不已，这一万块钱白花了！难道我的iPhone只能用到今年下半年吗？换个电话卡，不知道能不能使用5G电话呢？自己是不是亏了？”在笔者看来，这些问题只是很表面的，深入去探讨，大家其实担心的是自己是否需要换手机，是否需要换手机卡。经过研究，如今笔者也可算是明白了，下面跟大家解答一下这些疑惑。
第一，使用5G是一定要更换手机的。因为目前人们使用的4G手机不具备5G调制调解器，顶多支持4G网络，如果你希望使用5G网络，去感受5G带来的新体验，那么就需要换手机。但是大家也要明白，虽说5G时代已经到来，但是大家仍然可以继续使用4G网络。目前三大运营商正在陆续关闭2G、3G，但是4G网络不会这么快关闭。
第二，使用5G不一定需要更换手机卡。中国移动已经对外公布，从4G升级到5G无需更换SIM卡，可用现有4G卡直接接入5G网络。当然运营商同时也会为5G网络提供新的手机卡，为了更好的体验感，大家也可以进行更换。
事实上，虽说目前已经有部分城市试行5G，但距离真正的5G时代还是有一定距离的。5G网虽然理论网速较高，可达数十GB每秒，但是5G前期网络覆盖不完善，5G网目前因为频率问题，覆盖率不高，完成普及时间估计要很久。如今4G网络资费相对较低，只要运营商不限速，网速也是够快的，所以4G网络在未来三到五年时间内依然是主力，没有必要更换5G手机。
