Telephonymanager TM = (Telephonymanager) context.getsystemservice (Context.telephony_service);

Note: Some phone messages require the appropriate permissions.

Get the name of the service provider, such as Telecom, Unicom, mobile The first method is to obtain the IMSI code of the mobile phone, and to judge that it is China Mobile Unicom Telecom

Getsimoperatorname ()  //Returns the Service Provider Name (SPN). 

IMSI International Mobile Subscriber Identification Number (imsi:international Mobile subscriber identification number) is a sign that distinguishes a mobile user and is stored in a SIM card that can be used to differentiate valid information from a mobile user.

IMSI consists of MCC, MNC, Msin,

MCC is a mobile country number, consisting of 3 digits//uniquely identify the country to which the mobile customer belongs, our country is 460;

MNC for the network ID, composed of 2 digits//used to identify mobile customers belong to the mobile network, China Mobile is 00, Unicom is 01, Chinese telecom for 03;

Msin for mobile Customer identification Code, the use of equal length of 11 digits//Uniquely identify the domestic GSM mobile communication network to move customers.

It can be seen that imsi in the min number before the MCC, can distinguish each user from the country, so can achieve international roaming.

In the same country, if there are multiple CDMA operators, the MNC can be used to differentiate.

So to distinguish between mobile or unicom, just get the MNC field in the SIM card

String IMSI = Telmanager.getsubscriberid ();

if (Imsi!=null) {
 
 if (Imsi.startswith ("46000″) | | Imsi.startswith ("46002″)" 
 
 {
 
 // Because the mobile network number 46000 under the IMSI has been exhausted, so virtual a 46002 number, 134/159th segment used this number //  China Mobile  
 
}else Span style= "color: #0000ff;" >if (Imsi.startswith ("46001″) {
 
 // China Unicom  
 
}else if (Imsi.startswith ("46003″") {
 
 // China Telecom  
 
} 
 
}                 /span> 

The second method of

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

}

}
