How do we connect to a 5G NR network?
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) :
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#BND=(Fill in you bands here, see AT guide)
If you are using a Windows PC change the USBCFG to option 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

If you are still encountering problems connecting to a 5G network you can create a support ticket: https://techship.com/page/support/technical_support/. Please describe your problem and set up thoroughly and include the logs from this troubleshooting.
How to collect initial diagnostics data for Simcom 5G cellular modules when creating a Techship technical support ticket?
In order to troubleshoot and solve a technical problem, we ask you to please provide information about your host system and logs from the related Simcom 5G module when creating a technical support ticket.
This allows us to get a better understanding of what could relate to the experienced behaviour.
Please provide a detailed problem description and in what situations the problem is present or how it can be reproduced. Please also attach pictures showing the module assembled in your host device with RF interface cables connected between cellular module and the casing and provide datasheets for the antennas used if the problem appears to be a RF related problem such as no network registrations seen, or data throughputs not meeting your expectations etc.
Describe the host system:
-Hardware (system board, peripherals...)
-Operating system and detailed versions (E.g. Windows, Linux release, kernel version...)
-Drivers and driver versions
Identify the precise details of cellular module found on label (if not visible in attached picture)
-SKU / BOM or P/N code
-Serial / IMEI number
If your system is Linux based, please capture the terminal logs bellow:
ls -l /dev/serial/by-id
ls -l /sys/bus/usb-serial/devices
The log outputs from AT commands below can be collected from the cellular module by accessing the USB enumerated serial interfaces that accept AT commands. These are typically found as Modem or Serial type of interfaces in Window device manager, check their related COM port numbers from device manager and use a terminal software like Teraterm, Sscom or similar to send the AT commands to the cellular module. typically the default 115200 bitrate and 8N1 parity settings works well for collecting these details.
In Linux systems the USB serial ports are typically found in path /dev/ and named ttyUSB0, ttyUSB1, ttyUSB2, not all serial ports accept AT commands so you might have to check which of them are the correct one. Please note that if you have Modemmanager process running in your system, it likely already communicate on the USB serial interfaces so you should stop the Modemmanager service prior to attempting to collect the diagnostic logs. Minicom or other terminal software can be used to send the AT commands to the cellular module.
Start by sending an plain AT command followed by enter key to confirm that you get a OK reply and knowing that the AT communication is working.
Now start sending the following AT commands to the module and capture the output into a log text file and include them when creating the technical support ticket at Techship.com. If possible, provide the logs with a SIM card inserted and PIN unlocked, to allow the module to be in normal operational mode and registered in network.
