+
+## cl.telephony.1 sms模块SystemAPI接口入参变更
+
+已发布的部分电话子系统sms短信模块SystemAPI传入参数发生变化，不符合OpenHarmony接口规范。从API9开始做出以下变更：
+
+isImsSmsSupported接口新增一个传入参数slotId，表示卡槽号。
+
+
+
+**变更影响**
+
+基于此前版本开发的应用，需适配变更js接口的入参，否则会影响原有功能。
+
+
+
+**关键的接口/组件变更**
+
+- 涉及接口
+
+  isImsSmsSupported(callback: AsyncCallback<boolean>): void;
+  isImsSmsSupported(): Promise<boolean>;
+
+- 变更前：
+
+```js
+function isImsSmsSupported(callback: AsyncCallback<boolean>): void;
+function isImsSmsSupported(): Promise<boolean>;
+```
+
+- 变更后：
+
+```js
+function isImsSmsSupported(slotId: number, callback: AsyncCallback<boolean>): void;
+function isImsSmsSupported(slotId: number): Promise<boolean>;
+```
+
+
+
+**适配指导**
+
+新增一个入参，示例代码如下：
+
+callback方式
+
+```js
+let slotId = 0;
+sms.isImsSmsSupported(slotId, (err, data) => {
+      console.log(`callback: err->${JSON.stringify(err)}, data->${JSON.stringify(data)}`);
+});
+```
+
+promise方式
+
+```js
+let slotId = 0;
+let promise = sms.isImsSmsSupported(slotId);
+promise.then(data => {
+    console.log(`isImsSmsSupported success, promise: data->${JSON.stringify(data)}`);
+}).catch(err => {
+    console.error(`isImsSmsSupported failed, promise: err->${JSON.stringify(err)}`);
+});
+```
