Android运营商名称显示之PLMN与SPN

frameworks/opt/telephony/src/java/com/android/internal/telephony/uicc/SpnOverride.java:39: static final String PARTNER_SPN_OVERRIDE_PATH ="etc/spn-conf.xml";

spn-conf.xml

OPN 是指此SIM卡的提供商名称

PLMN 当前注册的网络提供商名称（ServiceState：setOperatorName(opNames[0], opNames[1], opNames[2]);//从modem得到的数据）

SPN 服务提供商名称（SPN(Service Provider Name)就是当前发行SIM卡的运营商的名称）

OPN和SPN都是提前预置在SIM卡中的网络提供商和服务提供商可能不是同一个企业，所以有事需要单独显示SPN
