How does Android obtain the local network provider? See the followingCode:

Public String getprovidersname () {string STR = "N/A"; try {This. imsi = This. telephonymanager. getsubscriberid (); system. out. println (this. imsi); If (this. imsi. startswith ("46000") STR = "China Mobile"; break; If (this. imsi. startswith ("46002") STR = "China Mobile"; break; If (this. imsi. startswith ("46001") STR = "China Unicom"; else if (this. imsi. startswith ("46003") STR = "China Telecom";} catch (exception localexception) {localexception. printstacktrace ();} return STR ;}


This. telephonymanager = (telephonymanager) paramcontext. getsystemservice ("phone "));

That's simple ....
