我也有时候遇到，来咨询一下。以上是一条完整的，其它的基本都是一致，直到拨号程序退出

您看一下您用的手机卡是不是物联网卡，从打印信息上看是识别到卡有问题，正常是 requestGetSIMStatus SIMStatus: SIM_READY，您这个是SIM_ABSENT，应该是卡没有正常识别，您可以换张SIM卡试试，尽量用普通手机卡，物联网卡需要apn拨号

对的 ，我们使用的是物联网卡。我们采购的设备都是使用的这种卡，有时候会出现这样的问题。不知道有什么好的解决方案？

zhichao 发表于 2021-9-30 16:29:38

应该是需要AT指令设置一些参数，比如
1. 物联网卡的APN
2. 物联网卡的鉴权模式：PAP还是CHAP，或者是认证回退
3. 物联网卡的用户名
4. 物联网卡的密码

具体可以百度一下
