To be able to connect to a 5G network both the module and SIM card need to have 5G technology support. If you have problems with NSA or SA for a specific band make sure that your module actually supports this as well. Read through your product’s hardware guide which can be found on the product’s page.

Support for 5G NSA/SA on a specific band can also be firmware dependent. Make sure that you have the latest firmware installed on your module.

This FAQ includes many different AT commands, both 3GPP standard and vendor specific commands, so it’s recommended to have your module’s AT guide with you while troubleshooting.

Perform a network scan with AT+COPS=? and check if your module can find any 5G networks. You can see if it’s a 5G network by looking at the last value in the quadruple. Depending on which technology you use this should be set to:

11 - NR_5GCN (NR connected to a 5G core Network)
12 - NGRAN (NG-RAN access technology)
13 - EUTRA_NR (Dual connectivity of LTE with NR)

If your module can find the 5G network, check your current network configuration with the read command AT+COPS? to make sure it’s set to the correct value. Similarly you can check the NR5G network registration status with the following AT command sequence (note this command only applies for 5G SA) :

AT+C5GREG=2

AT+C5GREG?

You can select the Wireless Data Service with AT+WS46:

36 - NG-RAN only
37 - NG-RAN and E-UTRAN
38 - NG-RAN, E-UTRAN and UTRAN
40 - NG-RAN and UTRAN

Telit 5G related AT commands:

Enable your 5G band with AT#BND
To enable/disable only the 5G bands AT#5GCTL can be used
Check that you're connected to a 5G band with AT#SERVINFO or AT#RFSTS
Check that your network supports 5G NSA with AT#5GLINKSTAT?

FN980 does not have SA enabled by default. To enable it run the following commands:

AT#FWSWITCH=0
AT#BND=(Fill in you bands here, see AT guide)
AT#REBOOT

If you are using a Windows PC change the USBCFG to option 2
AT#USBCFG=2

SIMCom 5G related AT commands:

Enable both SA and NSA with AT+CSYSSEL=”nr5g_disable”,0
Disable SA with AT+CSYSSEL="nr5g_disable",1
Disable NSA with AT+CSYSSEL=”nr5g_disable”,2
Configure 5G NSA bands with AT+CSYSSEL=”nsa_nr5g_band”
Configure 5G SA bands with AT+CSYSSEL=”nr5g_band”

Set your preferred mode with AT+CNMP
- 55 - WCDMA+LTE+NR5G
- 71 - NR5G
- 109 - LTE+NR5G

Sierra Wireless 5G related AT commands:

Display your 5GNR information with AT!NRINFO?

Enable/disable ENDC (NSA) and SA with AT!RTCA (note that these settings are not persistent across power cycles)

AT!GSTATUS not responding with NR5G fields and looks similar to:

NR5G RSRP (dBm): --- NR5G RSRQ (dB): ---

NR5G SINR (dB): —

The response details are dependent on the network providing the necessary information to the modem. To be sure you get these values the modem has to be in a data call in SA mode

Fibocom 5G related AT commands:

Select RAT with AT+GTRAT or RAT and Bands with AT+GTACT
- 14 - NR-RAN
- 16 - NR-RAN/WCDMA
- 17 - NR-RAN/LTE
- 20 - NR-RAN/WCDMA/LT
