-The **data** module provides basic mobile data management functions. You can obtain and set the default slot of the SIM card used for mobile data, and obtain the uplink and downlink connection status of cellular data services and connection status of the packet switched (PS) domain. Besides, you can check whether cellular data services and data roaming are enabled.

+# Telephony Error Codes
+
+## 8300001 Input Parameter Value Out of Range
+
+**Error Message**
+
+The input parameter value is out of range.
+
+**Description**
+
+This error code is reported if the value of the input parameter (for example, **slotId**) is not within the valid range. In this case, the API call will fail and the corresponding operation cannot be performed.
+
+**Cause**
+
+The input parameter value is invalid.
+
+**Solution**
+
+Enter a valid parameter value.
+
+
+
+## 8300002 Service Connection Error
+
+**Error Message**
+
+Operation failed. Cannot connect to service.
+
+**Description**
+
+This error code is reported if the attempt to connect to a service fails.
+
+**Cause**
+
+Service startup or IPC connection has failed.
+
+**Solution**
+
+Operation error. Try again later.
+
+
+
+## 8300003 System Internal Error
+
+**Error Message**
+
+System internal error.
+
+**Description**
+
+This error code is reported if an internal error has occurred.
+
+**Cause**
+
+The possible cause is that data read/write has failed because the network is abnormal.
+
+**Solution**
+
+Operation error. Try again later.
+
+
+## 8300004 SIM Card Not Detected
+
+**Error Message**
+
+Do not have sim card.
+
+**Description**
+
+This error code is reported if no SIM card is detected.
+
+**Cause**
+
+No SIM card is inserted or the SIM card is not properly inserted.
+
+**Solution**
+
+Insert the SIM card or remove and insert the SIM card again.
+
+
+## 8300999 Unknown Error
+
+**Error Message**
+
+Unknown error code.
+
+**Description**
+
+This error code is reported if an unknown error occurs.
+
+**Cause**
+
+An unexpected error occurs in the system. The possible cause is that error codes of the bottom layer are not within the processing range.
+
+**Solution**
+
+Operation error. Try again later.
+
+
+## 8301001 SIM Card Not Activated
+
+**Error Message**

-## Overview<a name="section315316685115"></a>
 
-If HiSysEvent logging is required for a component, you need to define a YAML file and [configure the YAML file path](#section123181432175135) in the **bundle.json** file. During compilation, the OpenHarmony compilation framework will use the Python compilation script to parse and verify all the YAML files configured in the **bundle.json** file. On completion, the compilation framework will summarize the configuration information in the YAML files and convert the information into a JSON file named **hisysevent.def**. After that, the compilation framework will put the JSON file to a specified path as the basis for the system to determine whether to log system events.

+### Function Introduction
+
+If HiSysEvent logging is required for a component, you need to define a YAML file and [configure the YAML file path](#configuring-the-yaml-file-path) in the **bundle.json** file. During compilation, the OpenHarmony compilation framework will use the Python compilation script to parse and verify all the YAML files configured in the **bundle.json** file. On completion, the compilation framework will summarize the configuration information in the YAML files and convert the information into a JSON file named **hisysevent.def**. After that, the compilation framework will put the JSON file to a specified path as the basis for the system to determine whether to log system events.
+
+
+### Basic Concepts
 
 Understanding the following concepts would be helpful for you in configuring HiSysEvent logging.
 
-- Event domain
-  Represents the domain to which an event belongs. It is specified by the **domain** field in the YAML file. For details, see [domain](#section123181432175123) in the example YAML file.
+- Event domain<br>Represents the domain to which an event belongs. It is specified by the **domain** field in the YAML file. For details, see [domain](#example) in the example YAML file.
 
-- Event name
-  Indicates the events in an event domain. For details, see [EVENT\_NAMEA/EVENT\_NAMEB](#section123181432175123) in the example YAML file.
+- Event name<br>Indicates the events in an event domain. For details, see [EVENT\_NAMEA/EVENT\_NAMEB](#example) in the example YAML file.
 
-- Parameter
-  Defines the key values in an event name. For details, see [__BASE/NAME1/NAME2](#section123181432175123) in the example YAML file.
+- Parameter<br>Defines the key values in an event name. For details, see [__BASE/NAME1/NAME2](#example) in the example YAML file.
 
 
-### Constraints<a name="section123181432175114"></a>
+### Constraints
+
+Constraints on the event domain, event name, and parameter
 
 - Each YAML file can contain only one event domain, and the domain name cannot be the same as that defined in other YAML files.
 
 - Zero or more event names can be defined for one event domain. The event names in the same event domain must be unique.
 
-- Multiple parameters can be defined for one event name. The parameters in the same event name must be unique. There must be one and only one parameter named **\__BASE** in each event name. See Table 1 for the fields of this parameter and Table 2 for the fields of other custom parameters.
-
-  **Table 1** Fields in the \__BASE parameter
+- Multiple parameters can be defined for one event name. The parameters in the same event name must be unique. There must be only one parameter named **__BASE** in each event name. See Table 1 for the fields of this parameter and Table 2 for the fields of other custom parameters.

-### Example<a name="section123181432175123"></a>
+### Example
 
--   In the example YAML file, the event domain name is **MODULEA**. The event domain contains two events named **EVENT\_NAMEA** and **EVENT\_NAMEB**.
--   **EVENT\_NAMEA** is defined as a critical event of the fault type. The event contains the **NAME1** parameter of the string type, the **NAME2** parameter of the string type, and the **NAME3** parameter of the unsigned short integer type. Therefore, you can perform [real-time subscription](subsys-dfx-hisysevent-listening.md) to the event based on the event domain **MODULEA** and event name **EVENT\_NAMEA**.
--   **EVENT\_NAMEB** is defined as a general event of the statistics type. The event contains the **NAME1** parameter of the unsigned short integer type and the **NAME2** parameter of the integer type. Because two event tags named **tag1** and **tag2** are defined for **EVENT\_NAMEB** in the **\__BASE** parameter, you can perform [real-time subscription](subsys-dfx-hisysevent-listening.md) to the event based on the event domain **MODULEA** and event name **EVENT\_NAMEB**, or based on the event tag.
+- In the example YAML file, the event domain name is **MODULEA**. The event domain contains two events named **EVENT_NAMEA** and **EVENT_NAMEB**.

+## cl.powermgr.3 System Common Event Behavior Change
+
+The following common events are provided in the battery information through [@ohos.commonEventManager (common event module)](https://gitee.com/openharmony/docs/blob/master/en/application-dev/reference/apis/js-apis-commonEventManager.md):
+
+- COMMON_EVENT_BATTERY_LOW: common event for low battery level. It includes the remaining battery in percentage.
+- COMMON_EVENT_BATTERY_OKAY: common event for normal battery level. It includes the remaining battery in percentage.
+- COMMON_EVENT_POWER_CONNECTED: common event for connection to an external power supply. It includes the type of the power supply to which the device is connected.
+- COMMON_EVENT_POWER_DISCONNECTED: common event for disconnection from an external power supply. It includes the type of the power supply from which the device is disconnected.
+- COMMON_EVENT_CHARGING: common event for starting of battery charging. It includes the battery charging status.
+- COMMON_EVENT_DISCHARGING: common event for ending of battery charging. It includes the battery charging status.
+
+Changed the method of obtaining data from common events from **CommonEventData.data** to **CommonEventData.code**.
+
+#### Change Impact
+
+The application developed based on earlier versions needs to adapt the method for obtaining common events in the battery information. Otherwise, the original service logic will be affected.
