I’m having no luck connecting to an AT&T network. I’ve confirmed the sim works in another device with the APN “phone”. I’m not really sure where to go from here, any help would be appreciated.
Thanks
Please try following the troubleshooting guide below:
The device cannot see the network (+CSQ: 99,99)
+QCFG: “nwscanseq”,010203 >> indicates it is looking for the GSM first, for fast network searching we can change it to CAT M1 using AT+QCFG=“nwscanseq”,020301
+QCFG: “nwscanmode”,0 >> is automatic, which looks for GSM network too, We can change it to LTE only networks using AT+QCFG=“nwscanmode”,3
+QCFG: “iotopmode”,2 >> indicates Network search is under both CAT M1 and CAT NB1 RATs. We can change it to CAT M1 only using AT+QCFG=“iotopmode”,0
+QCFG: “band”,0x1,0x10,0x80000 >> indicates it is searching for LTE B5 band only. AT+QCFG=“band”,F,180A,180A will let you search all the LTE bands in US.
This will speed up your network search and network registration.
Once the module is configured to the desired settings, power cycle the module and check the following after 10s of module boot up.
