Zhao Yazhi _android Get the native operator, the mobile phone number part can get

Mobile phone numbers are not all available. Only a part of it can be obtained.

This is because the mobile operator does not write data from the mobile phone number to the SIM card. The SIM card has only a unique number. For network and equipment identification that is the IMSI number, the cell phone signal can be said to pass through this number in the network, not mobile phone number.

Imagine. After your SIM is lost, do you want to replace a new one with a replacement number?

No, it is because the IMSI number in your mobile phone number is changed to the IMSI number of the new SIM card.

So why does the phone number have to show it?

This is like a variable, and when the mobile operator assigns it a value, it will naturally have a value. No value is naturally empty.

The domestic SIM card is IMSI number, no phone number exists on the machine. Only when you have contact with the base station. The operator assigns you the number.

But I also wrote a class implementation to get the operator
