AT (ATtention) commands for UE Testing

TechRadar · February 22, 2023, 11:30pm

AT (ATtention) commands can be used to test a UE (User Equipment) in a telecommunication network.

Here are some commonly used AT commands for testing UE:

AT: This command is used to check if the UE is responding.
AT+CGSN: This command is used to get the serial number of the UE.
AT+CGMI: This command is used to get the manufacturer name of the UE.
AT+CGMM: This command is used to get the model name of the UE.
AT+CPIN: This command is used to enter the SIM card PIN code.
AT+CSQ: This command is used to check the signal strength of the network.
AT+CREG?: This command is used to check the network registration status of the UE.
AT+CGACT?: This command is used to check the PDP (Packet Data Protocol) activation status of the UE.
AT+CGATT?: This command is used to check the attachment status of the UE to the GPRS (General Packet Radio Service) network.
AT+COPS?: This command is used to get the network operator’s name and information.
ATD: This command is used to dial a phone number.
ATA: This command is used to answer an incoming call.
ATH: This command is used to hang up a call.

Here are some useful links to AT command references and resources:

Note that the exact set of commands supported by a UE depends on its manufacturer and model, as well as the network it is connected to.
