4G模块无法识别到SIM卡

风儿吹

SIM卡使用的是移动卡，两张在手机上都能正常使用，把卡装在开发板上，使用手册的4G测试方法一直没有通过，两张卡都不行。

网上搜索到AT查询SIM卡命令，AT+CPIN？，显示的是CME  ERROR：10，是没有插入SIM卡的意思，两张卡都是一样。

您的手机卡是插在4g模块下边的卡槽上了吗，您的打印信息中显示的就是SIM_ABSENT，卡没有识别。您可以再看看，是否将sim卡插错位置，有没有将SIM卡插反

输入echo  “AT^LEDCTRL=1”>/dev/ttyUSB2 报错，ERROR 。

您用的4G模块不是我们的吧，我们的4G固件版本和您的不一致，您的是requestBaseBandVersion EC20CEHDLGR06A07M1G，我们的不是这个

插SIM卡的位置有几个？

能用做4G测试的就只有4G旁边的那个，在SD卡卡槽附近
