华为鸿蒙系统是否不支持安装应用到SD卡里？

概述

本示例展示了电话服务中SIM卡相关功能，包含SIM卡的服务提供商、ISO国家码、归属PLMN号信息，以及默认语音卡功能。

样例展示

基础信息

介绍

本示例使用sim相关接口，展示了电话服务中SIM卡相关功能，包含SIM卡的服务提供商、ISO国家码、归属PLMN号信息，以及默认语音卡功能。

效果预览

使用说明：

1.若SIM卡槽1插入SIM卡则SIM卡1区域显示为蓝色，否则默认为白色。

2.点击SIM卡1区域，弹窗显示SIM卡1的相关信息，再次点击面板消失。

3.默认拨号的SIM卡其按钮背景色为蓝色，目前只展示默认拨号的SIM卡，更改默认拨号卡功能暂不支持。

4.呼叫转移界面功能暂不支持，故点击按钮无实际操作。

具体实现

• 该示例主要通过hasSimCard方法获取指定卡槽SIM卡是否插卡，getSimState方法获取指定卡槽的SIM卡状态，SimState方法判断SIM卡状态，isSimActive方法获取指定卡槽SIM卡是否激活，getSimSpn方法获取指定卡槽SIM卡的服务提供商名称，getISOCountryCodeForSim方法获取指定卡槽SIM卡的ISO国家码，getSimOperatorNumeric方法获取指定卡槽SIM卡的归属PLMN号，getDefaultVoiceSlotId方法获取默认语音业务的卡槽ID等开发电话服务的相关功能。
