TelephonyManager is a service class that manages the call status and network information of a mobile phone. It provides a large number of getXxx () methods to obtain information about the telephone network.

TelephonyManager class overview:

It can be used to access telephone service information on a device. Applications can use this class to determine the telephone service and status and access some types of user information. The application can also register a listener to receive notifications of phone status changes.

You cannot directly instantiate this class. Instead, you can useContext. getSystemService (Context. TELEPHONY_SERVICE)Method to initialize the TelephonyManager instance.

Note that you can access certain phone information permission-protected .. Your application should have some permissions to access the location and status of your mobile phone.

The TelephonyManager class provides the following methods:

 

Public Methods
Int	GetCallState () Returns a constant indicating the call status on the device.
CellLocation	GetCellLocation () Returns the current location of the device.
Int	GetDataActivity () Returns a constant representing the type of the active data connection.
Int	GetDataState () Returns a constant indicating the current data connection status.
String	GetDeviceId () Return a unique device ID, for example, imei gsm and meid cdma.
String	GetDeviceSoftwareVersion () Return the software version number of the device, for example, the IMEI/sv gsm mobile phone number.
String	GetLine1Number () Return the phone number of Line 1. For example, MSISDN is used for GSM.
List <NeighboringCellInfo>	GetNeighboringCellInfo () Return the information of the adjacent cell of the device.
String	GetNetworkCountryIso () Return the country code of the registered network operator.
String	GetNetworkOperator () Returned MCC + registered network operator of a multinational company
String	GetNetworkOperatorName () Returns the name of the registered Network Carrier.
Int	GetNetworkType () Returns a constant representing the radio technology (network type) currently used on the device ).
Int	GetPhoneType () Return the type of the device (mobile phone ).
String	GetSimCountryIso () Returns the country code of the SIM card carrier.
String	GetSimOperator () Return the SIM card of the provider of MCC + Multinational Corporation (mobile country code + mobile network code.
String	GetSimOperatorName () The name of the service provider ).
String	GetSimSerialNumber () Returns the serial number of the SIM card, if applicable.
Int	GetSimState () Returns a constant representing the status of the SIM card device.
String	GetSubscriberId () Return a unique user ID. For example, IMSI is a GSM mobile phone.
String	GetVoiceMailAlphaTag () Retrieve the letter identifier associated with the voicemail number.
String	GetVoiceMailNumber () Return the voicemail number.
Boolean	HasIccCard ()
Boolean	IsNetworkRoaming () Returns true. If the device is considered to be roaming the current network, it supports GSM.
Void	Listen (PhoneStateListener listener, int events) Register a listener object to receive notifications that change the status of a specified phone number.

How to read SIM card text messages in Android

Open the default information program of the system, click menu, and there is an option "manage SIM card information" after entering it. After clicking it, you can view and edit the SIM card information.
 
In Android, how does one obtain information in the SIM card? If there is a short message in the SIM card or other information written in the SIM card?

I don't know what information you mean? Is it used to obtain the contact information in the SIM?
