Android gets SIM card carrier Information

Android gets SIM card carrier Information

Telephonymanager TM = (telephonymanager) Context. getsystemservice (context. telephony_service );
Use of telephonymanager
Telephonymanager provides the entry for obtaining Communication Service Information on the device. The application uses this method to obtain the service provider or status of the phone. The program can also register a listener to listen for changes in the phone status.
You do not need to instantiate this class directly. Use context. getsystemservice (context. telephony_service) to obtain the instance of this class.

Note: Some phone information requires the appropriate permissions.
Invalid Method

Getsimoperatorname ()
Returns the service provider name (SPNs). // obtain the service provider name, such as China Telecom, China Unicom, and China Mobile.
Use the following method
Method 1:
Obtain the imsi code of the mobile phone and determine whether it is China Mobile/China Unicom/China Telecom

Telephonymanager telmanager = (telephonymanager) getsystemservice (context. telephony_service );

 

/** Get the imsi code of the SIM card
* Unique SIM card ID: imsi International Mobile User identification code (imsi: International Mobile Subscriber identification number) is the identifier for distinguishing mobile users,
* It is stored in the SIM card and can be used to distinguish valid information of mobile users.

Imsi is composed of MCC, MNC, and msin. MCC is a mobile country number and consists of three digits,
* The only country that identifies a mobile customer is China's 460. the MNC is the network ID, which consists of two digits,
* It is used to identify the mobile network to which mobile customers belong. China Mobile is 00, China Unicom is 01, and China Telecom is 03;

Msin is a mobile customer identification code consisting of 11 digits.
*

Uniquely identifies China Mobile clients in China's GSM mobile communication network. To distinguish between mobile and Unicom, you only need to obtain the MNC field in the SIM card.
*/

 

 

String imsi = telmanager. getsubscriberid ();

If (imsi! = NULL ){
If (imsi. startswith ("46000") | imsi. startswith ("46002 ″))

{// Because imsi under mobile network number 46000 is used up, A 46002 number is virtualized, and this number is used in segment 134/159.
// China Mobile

} Else if (imsi. startswith ("46001 ″)){

// China Unicom

} Else if (imsi. startswith ("46003 ″)){

// China Telecom

}
}

 

 

Method 2
Telephonymanager telmanager = (telephonymanager) getsystemservice (context. telephony_service );
String operator = telmanager. getsimoperator ();

If (Operator! = NULL ){
If (operator. Equals ("46000") | Operator. Equals ("46002") | Operator. Equals ("46007 ″)){

// China Mobile

} Else if (operator. Equals ("46001 ″)){

// China Unicom

} Else if (operator. Equals ("46003 ″)){

// China Telecom

}

String simoperator = Tel. getsimoperator ();

Imsi has a total of 15 digits, and its structure is as follows:
MCC + MNC + min
MCC: Mobile country code, mobile country code, 3 digits in total, 460 for China;
MNC: mobile network code, mobile network code, two digits in total, China Telecom 03, China Mobile 02, China Unicom GSM 01, a typical imsi Number of 460030912121001;
Min has a total of 10 digits, and its structure is as follows:
09 + m0m1m2m3 + ABCD
Among them, the m0m1m2m3 and the h0h1h2h3 in the mdn number can have a correspondence relationship, and the four bits of ABCD are freely allocated.
We can see that imsi has added MCC before the min number to differentiate the countries where each user is from, so that it can implement international roaming. In the same country, if there are multiple CDMA operators, they can be differentiated through MNC.
