Dialing Failure Problem

<p>[TOC]</p> <h3>I. Problem Phenomenon</h3> <p>The device cannot dial successfully and keeps showing dial-up failure, resulting in the device not being able to connect to the central server.</p> <h3>II. Analysis Steps</h3> <p>You can follow these steps to troubleshoot the causes of the problem one by one: 1、Check the module identification status. 2、Check the SIM card identification status. 3、Check the antenna and signal status. 4、Check the matching status of dialing parameters and SIM card. 5、Check the SIM card network and traffic status. 6、Check the binding status of the IoT card. 7、Check whether the WIFI network is connected.</p> <h3>III. Operating Instruction</h3> <h4>1、Check the module identification status</h4> <p>Check the module identification status in the device menu,-DEVICE STATE, if the type is displayed, the module exists and is identified successfully.</p> <p><img src="http://118.195.179.210:9000/server/index.php?s=/api/attachment/visitFile&amp;amp;sign=a7c45d83d5a994f3bcc8c7b6105b3561" alt="" /></p> <h4>2、Check the SIM card identification status</h4> <p>Check whether the network type of the host and the installed SIM card correspond. Or SIM card is not activated, or SIM expired without traffic. Check the SIM card recognition status in DEVICE STATE in the device menu, and the presence of the SIM card indicates that the SIM card is successfully recognized.</p> <p><img src="http://118.195.179.210:9000/server/index.php?s=/api/attachment/visitFile&amp;amp;sign=08d660dac31fe7a1b7c7dee6340baf07" alt="" /></p> <h4>3、Check the antenna and signal status</h4> <p>Check whether the 4G antenna is connected (some products are built-in antenna) and whether the SIM signal value shown in the device status is available or the value is low (normal dial-up success can access the Internet for more than 15 and up to 31).</p> <p><img src="http://118.195.179.210:9000/server/index.php?s=/api/attachment/visitFile&amp;amp;sign=b4fd7dbc6d13b65e7fce042c030e8773" alt="" /></p> <h4>4、Check the matching status of dialing parameters and SIM card</h4> <p>In general, dialing parameters will be automatically recognized, but also need to check the corresponding SIM card type, does not correspond to the need to modify the corresponding network type in the host menu (4G Unicom for FDDLTE-2, 4G Telecom for FDDLTE-1, Mobile for 4G-TDDLTE), need to open the dialing enable.</p> <p><img src="http://118.195.179.210:9000/server/index.php?s=/api/attachment/visitFile&amp;amp;sign=6784c614aae8508b1fcbe309543f6348" alt="" /></p> <h4>5、Check the SIM card network and traffic status</h4> <p>Can access the cell phone, whether the phone can identify successfully and normal Internet access, can make calls and send text messages (using the SMS function of the device), or to the corresponding online business office consulting to view the SIM card traffic status.</p> <h4>6、Check the binding status of the IoT card</h4> <p>If an IoT card is used, please use a normal SIM card to go for comparison.</p> <h4>7、Check whether the WIFI network is connected</h4> <p>Check if the device is connected to the wifi network in the network information, WiFi station mode is enabled, because WiFi priority is greater than 4G, so when the two coexist, 4G will show dial-up failure, but when WiFi is AP mode, it can coexist;</p> <p><img src="http://118.195.179.210:9000/server/index.php?s=/api/attachment/visitFile&amp;amp;sign=f7510c6a8e38a21d0259e52d180e36ff" alt="" /></p> <p><img src="http://118.195.179.210:9000/server/index.php?s=/api/attachment/visitFile&amp;amp;sign=404b641bae3de2bd262bd46bd525e886" alt="" /></p> <hr />
