Android gets IMSI information (judging is mobile, Unicom, Telecom Mobile card)

First we need to know mobile phone IMSI number 3 bits 460 is the country, followed by 2 bits 00 02 is China Mobile, 01 is China Unicom, 03 is Chinese telecom. So the first step is to get the phone IMSI number: The code is as follows

1     /**2 * Get IMSI information3      * @paramContext4      * @return5      */6      Public StaticString Getphoneimsi (context context) {7Telephonymanager mtelephonymgr =(telephonymanager) Context8 . Getsystemservice (context.telephony_service);9LOG.V ("LJC", "Get Getsubscriberid" +Mtelephonymgr.getsubscriberid ());Ten         returnMtelephonymgr.getsubscriberid (); One}

Or:

1     /**2 * Check if Telecom Mobile card3      * 4      * @returnThe Telco card returns true otherwise false5      */6      Public BooleanChecksimcarl (Context context) {7         BooleanValue =false;8String IMSI =Getphoneimsi (context);9         if(IMSI! =NULL) {Ten             if(Imsi.startswith ("46003")) OneValue =true; A         } -         returnvalue; -         //IMSI Front 3 bit 460 is the country, followed by 2 bit 00 02 is China Mobile, 01 is China Unicom, 03 is Chinese telecom. Which the         //if (Imsi.startswith ("46000") | | Imsi.startswith ("46002")) { -         //providersname = "China Mobile"; -         //} else if (Imsi.startswith ("46001")) { -         //providersname = "China Unicom"; +         //} else if (Imsi.startswith ("46003")) { -         //providersname = "China Telecom"; +}
