Android开发中,可能需要区分当前的phone是gsm或cdma类型,有时候cdma phone注册到4G网络时,调用Phone@getPhoneType获取到的类型为PHONE_TYPE_GSM,其实除了这个方法获取sim卡类型,还可以根据iccid会mccmnc来区分当前的sim卡类型,甚至可以区分得更详细(移动、联通、电信),具体方式如下:
//Only one sim card private static final int PHONE_TYPE_CMCC = 0; private static final int PHONE_TYPE_UNICOM = 1; private static final int PHONE_TYPE_CDMA = 2; private int getPhoneType() { int phoneType = -1; TelephonyManager tm = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE); String mccMnc = tm.getSimOperator(); if ("46000".equals(mccMnc) || "46002".equals(mccMnc) || "46007".equals(mccMnc) || "46008".equals(mccMnc) || "45412".equals(mccMnc)) { phoneType = PHONE_TYPE_CMCC; } else if ("46001".equals(mccMnc) || "46006".equals(mccMnc) || "46009".equals(mccMnc)) { phoneType = PHONE_TYPE_UNICOM; } else if ("46003".equals(mccMnc) || "46005".equals(mccMnc) || "46011".equals(mccMnc) || "45502".equals(mccMnc) || "45507".equals(mccMnc)) { phoneType = PHONE_TYPE_CDMA; } return phoneType; }
这样可以直接区分当前sim卡所属的运营商,然后根据运营商区分PHONE_TYPE_GSM(移动、联通)或PHONE_TYPE_CDMA(电信)类型
