自建研究基站，00101以外的PLMN不可用， RM5xxQ 系列

物联网模组 LTE-Advanced & 5G 模组

自建研究5G基站，PLMN使用00101一切正常，在尝试把PLMN改为别值时出现了问题。

AT+COPS=?运营商搜索可识别，但自动注册失败，使用AT+COPS=1,2,"20896"手动注册显示OK仍然失败。核心网并未触发注册，问题出在基站跟模块之间。使用测试频率为3.619080GHz
请问问题可能出在哪，怎么查看导出模块日志？另外几个COM口看吗？

AT+COPS=?
+COPS: (1,"208 96","208 96","20896",12),(3,"CHINA MOBILE","CMCC","46000",7),(1,"CHN-CT","CT","46011",7),(3,"CHINA BROADNET","CBN","46015",7),(3,"CHN-UNICOM","UNICOM","46001",12),(3,"CHINA MOBILE","CMCC","46000",12),(1,"CHN-CT","CT","46011",12),(3,"CHN-UNICOM","UNICOM","46001",2),(3,"CHINA BROADNET","CBN","46015",12),(3,"CHN-UNICOM","UNICOM","46001",7),,(0-4),(0-2)

OK

是否跟模块内置的运营商配置文件有关？

Hi @zhou_leo
可能跟MBN选择有关，可以尝试改为选择row_mbn试试。
修改手动选择row_mbn：
at+qmbncfg=“AutoSel”,0
AT+QMBNCFG=“SELECT”,“ROW_Commercial”
AT+CFUN=1,1

默认自动选择MBN：
at+qmbncfg=“AutoSel”,1
AT+CFUN=1,1

十分感谢，这对我很有帮助。
