什麼是 iSIM(整合式 SIM 卡)及它如何運作?

iSIM(整合式 SIM 卡)的運作方式與 eSIM 相同。

由於 SIM 卡直接整合至裝置,無需插入實體晶片。

eSIM 是傳統 SIM 卡的小型版本,支援相同功能。

不同之處在於 eSIM 無法移除,因為直接嵌入智慧型手機的電路板。

iSIM 則更進一步,

它體積更小,並連接到一樣小型的數據機,內嵌於手機的處理器中,也就是「系統單晶片」(SoC)。

iSIM 有許多優點。

首先,因為尺寸小於 1mm2,可為智慧型手錶等小型電子裝置提供行動網路,也為整合更強力的電池留下了空間。

此外,iSIM 更為安全。

由於它所在的位置及尺寸大小,我們實體上無法接觸到。此外,iSIM 整合在處理器中,因此提供了多一層的認證,以加強保護個人資料。

最後,使用此技術有助於降低製造傳統 SIM 卡插槽的相關成本。
