SIM卡正逐渐被嵌入式SIM(eSIM)取代，谷歌Pixel 10系列成为最新采用eSIM的手机。eSIM作为焊在主板上的可编程芯片，能存储多个号码且节省空间，苹果iPhone 14已率先取消物理卡槽。尽管eSIM有优势，但作者在体验后表示后悔这一转变。

SIM卡即将消亡：一位科技编辑的eSIM初体验

曾经承载用户移动身份的小塑料片——SIM卡，正面临被时代淘汰的命运。为给其他元件腾出空间，谷歌Pixel 10系列成为最新一款取消物理卡槽的旗舰机，这迫使长期回避eSIM的笔者不得不首次尝试这项技术，结果却令人懊悔不已。

演进历程 SIM卡技术自90年代诞生以来，经历了信用卡大小的初代标准，到miniSIM、microSIM的迭代，最终演变为如今指甲盖大小的nanoSIM。但即便如此，智能手机内部空间仍寸土寸金，2016年推出的eSIM标准应运而生。

技术特性 与传统可插拔SIM卡不同，eSIM是直接焊接在主板上的可编程芯片。其优势在于：支持存储多张虚拟SIM、通过软件切换运营商、杜绝SIM卡被盗风险，且占用空间仅为物理卡的一半。这也解释了为何厂商纷纷弃用传统卡槽——苹果iPhone 14系列就通过取消卡槽，为国际版换来了约8%的电池容量提升。

市场现状 虽然谷歌今年才在美版Pixel 10系列实现eSIM独占，但与国际版相比并未带来明显硬件升级，这种"为变而变"的做法，正是笔者体验后深感遗憾的关键所在。

以下是评论内容的总结，平衡呈现不同观点：

支持eSIM的观点： 1. 便利性高，特别是国际旅行时能快速激活本地号码 - "being able to just show up in a country, download an app, and have a working local number within minutes is fantastic" (abigail95) - "eSIMs are perfect for travel" (xvilka)

2. 技术优势，无需物理卡槽
   • "I didn't have to try to track down my sim slot key...it took about 5 minutes" (mayanraisins)
   • "The major advantage is now that the expensive...can be replaced with a few standardized API calls" (waweic)

反对eSIM的观点： 1. 激活和迁移问题 - "Had to go into a store and have them sort it out there" (LeafItAlone) - "My telco requires that I receive an SMS on my eSIM to move it to new phone" (izacus)

2. 隐私和控制权担忧
   • "eSIMs are another way for big tech and government to track and identify you" (ifh-hn)
   • "well yeah, of course esim is shitty, as is everything imposed by big tech monopolies" (shlip)

中立/具体场景分析： 1. 物理SIM卡仍有价值 - "Main as traditional sim, esim for travel" (BoredPositron) - "I just swapped boring old plastic card in a minute" (Yizahi)

2. 技术实现问题
   • "SIM cards have always been secure elements...A 'SIM' should just be a keypair" (kevincox)
   • "Nobody has been able to convince me that esim is not just going back in time 15+ years" (birdman3131)

消费者选择权争议： - "why does he purchase a phone without those? By doing so you are confirming...the right choice" (forty) - "My min spec requirements for a phone are...physical dual SIM support" (secondcoming)
