Analysis of telephonymanager telephone related information management in Android

Sometimes we want to obtain information about the machine, such as sim card information and mobile phone developer information. At this time, we can use telephonymanager. Let's take a look at a detailed introduction to the code found on the Internet.

The SIM card information is as follows:
