大大有沒有嘗試過，先把SIM退出，用橡皮擦把金手指(金屬接點處)擦過一次試試看呢？
或是直接跟電信公司提出SIM卡更換的服務，表明有讀取接觸不良的問題應該可以免費可以問問看
多數這種狀況應該跟手機比較沒關係，都是卡的接觸比較多，之前遇到是這樣
除非～～手機的SIM卡槽～～有鬆脫現象

I encountered an issue where the SIM card cannot be read several times. Thankfully, I contacted a Locksmith for assistance, and they quickly resolved the problem. They are not only helpful with locks but can also provide solutions for unexpected tech issues like this.

I had a frustrating experience with my SIM card, as it couldn't be read several times. Thankfully, I switched to Sim Cards 4 Travel, and it worked flawlessly throughout my journey. Highly recommended for reliable connectivity.

我過去遇到的作法是  直接去電信門市換張新SIM卡

卡也是會壞掉的

這個方式還沒有試過，之後若有遇到類似的問題試試看能否解決。
