- /proc/516/exe → /usr/sbin/ModemManager
这个ModemManager要停掉； - 模块现在只能在2G网络，国内许多地方2G都退网了，检查下相关配置吧。
ModemManager关掉之后还是不行，执行QCM无法拨号上网，另外2G网络这个该如何恢复，肯是误操作了，SIM卡我用的是移动的4G卡

天线是不是没接？
AT+QCFG=“nwscanmode”
天线接了，另外请教一下EC200A-CN GA是否支持使用GobiNet,现在我看一直是使用的是ECM模式，使用udhcpc也不能连接网络，能否提供一下这个模块的重置AT指令
这个模组是不支持GobiNet的。
从上面的日志看，应该是天线有问题。
