+## cl.telephony.1 sms模块接口变更
+
+sendMessage接口作废弃处理，变更为sendShortMessage接口。
+
+**变更影响**
+
+从API version 10开始，sendMessage接口废弃。应用需要自行适配为sendShortMessage。接口功能不变。
+
+**关键的接口/组件变更**
+
+修改前的接口原型：
+
+```js
+function sendMessage(options: SendMessageOptions): void;
+```
+
+修改后的接口原型：
+
+```js
+function sendShortMessage(options: SendMessageOptions, callback: AsyncCallback<void>): void;
+function sendShortMessage(options: SendMessageOptions): Promise<void>;
+```
+
+
+
+**适配指导**
+
+使用变更后的接口，示例代码如下：
+
+```js
+let sendCallback = function (err, data) {
+    console.log(`sendCallback: err->${JSON.stringify(err)}, data->${JSON.stringify(data)}`);
+}
+let deliveryCallback = function (err, data) {
+    console.log(`deliveryCallback: err->${JSON.stringify(err)}, data->${JSON.stringify(data)}`);
+}
+let slotId = 0;
+let content = '短信内容';
+let destinationHost = '+861xxxxxxxxxx';
+let serviceCenter = '+861xxxxxxxxxx';
+let destinationPort = 1000;
+let options = {slotId, content, destinationHost, serviceCenter, destinationPort, sendCallback, deliveryCallback};
+sms.sendShortMessage(options, (err) => {
+    console.log(`callback: err->${JSON.stringify(err)}`);
+});
+```
+
+```js
+let sendCallback = function (err, data) {
+    console.log(`sendCallback: err->${JSON.stringify(err)}, data->${JSON.stringify(data)}`);
+}
+let deliveryCallback = function (err, data) {
+    console.log(`deliveryCallback: err->${JSON.stringify(err)}, data->${JSON.stringify(data)}`);
+}
+let slotId = 0;
+let content = '短信内容';
+let destinationHost = '+861xxxxxxxxxx';
+let serviceCenter = '+861xxxxxxxxxx';
+let destinationPort = 1000;
+let options = {slotId, content, destinationHost, serviceCenter, destinationPort, sendCallback, deliveryCallback};
+let promise = sms.sendShortMessage(options);
+promise.then(() => {
+    console.log(`sendShortMessage success`);
+}).catch(err => {
+    console.error(`sendShortMessage failed, promise: err->${JSON.stringify(err)}`);
+});
+

+## cl.telephony.2 sim模块接口变更
+
+getSimTelephoneNumber接口权限变更，由ohos.permission.GET_TELEPHONY_STATE变更为ohos.permission.GET_PHONE_NUMBERS。
+
+**变更影响**
+
+从API version 10开始，getSimTelephoneNumber接口权限变更为ohos.permission.GET_PHONE_NUMBERS。
+
+应用需要修改为申请权限ohos.permission.GET_PHONE_NUMBERS。接口功能不变。
+
+**关键的接口/组件变更**
+
+修改前的接口原型：
+
+```js
+  @permission ohos.permission.GET_TELEPHONY_STATE
+  function getSimTelephoneNumber(slotId: number, callback: AsyncCallback<string>): void;
+
+  @permission ohos.permission.GET_TELEPHONY_STATE
+  function getSimTelephoneNumber(slotId: number): Promise<string>;
+```
+
+修改后的接口原型：
+
+```js
+  @permission ohos.permission.GET_PHONE_NUMBERS
+  function getSimTelephoneNumber(slotId: number, callback: AsyncCallback<string>): void;
+  
+  @permission ohos.permission.GET_PHONE_NUMBERS
+  function getSimTelephoneNumber(slotId: number): Promise<string>;
+```
+
+
+
+**适配指导**
+
+使用变更后的接口，示例代码如下：
+
+module.json中申请权限需要更换或者添加ohos.permission.GET_PHONE_NUMBERS。
+
+```js
+"requestPermissions" : [
+    {
+        "name": "ohos.permission.GET_PHONE_NUMBERS",
+        "reason": "$string:GET_PHONE_NUMBERS"
+       }
+]
+```
+
+```js
+"requestPermissions" : [
+    {
+        "name": "ohos.permission.GET_PHONE_NUMBERS",
+        "reason": "$string:GET_PHONE_NUMBERS"
+       }
+]
+```
