卡和模组的IMEI是绑定的，卡在其他设备上也是可以上网的

那换张卡（普通的手机卡） 插上去能用吗？

可以插下

AT+CEER?

AT+QCEER

不一定能看出来。

AT+QCFG=”band”

这个有没有问题。

EC20CEFRSGR08A07M2G说是模块固件不支持物联网卡，是不是要升级到5Mxx才行是不

10

先用自己的手机卡看看能不能注网。

要看PS域没问题才能激活PDP.

我好像发现了一个问题，27,99就能注册，23,99就注册不了，但是23,99都-83dBm了吧

好像又正常了，拨号也能正常上网了 就是很卡

14

现在有一个问题就是插入物联网卡信号就是23,99，插入自己的手机卡就是99,99

15

这个就是没有注网成功。

16

是这个LIMSRV字符吗

17

是的。“LIMSRV” 用户设备正在小区上据守，但尚未在网络上注册。
