What is a SIM Card?

In short, SIM stands for Subscriber Identification Module. It’s what connects a phone to a specific carrier and gives it unique identifiers like a phone number. In simpler terms, it’s a small card that allows your phone to get service from a carrier.
简而言之，SIM代表订户识别模块。 它是将电话连接到特定运营商并为其提供唯一标识符(例如电话号码)的要素。 简单来说，这是一张小卡片，可让您的手机从运营商处获得服务。
There are a few different sizes of SIM Cards available: Standard SIM, Micro SIM, and Nano SIM, each of those progressively smaller than the previous one. While all three are still used in a variety of phones, Nano SIM has been the most popular choice over the last few years.
有几种不同大小的SIM卡可用：标准SIM卡，Micro SIM卡和Nano SIM卡，每种尺寸都比前一种逐渐减小。 尽管这三款手机仍在各种手机中使用，但Nano SIM在过去几年中一直是最受欢迎的选择。
