DC-Unlocker allows you to send AT commands directly to your modem's COM port. This is useful for: dc-unlocker commands list

Switching Modes: Disabling virtual CD-ROMs or SD card readers to free up system resources.

Network Locking: Checking if your device is actually locked or checking the remaining unlock attempts.

Signal Diagnostics: Getting detailed signal strength reports (RSSI). Essential Huawei Commands

Huawei modems often use specific command prefixes for advanced configuration. AT^SETPORT: Configures the modem's active ports.

Example: AT^SETPORT="A1,A2;2,7" disables the CD and SD modes while keeping the NDIS and PCUI interfaces active.

AT^U2DIAG: Used to switch between modem, CD-ROM, and card reader modes. AT^U2DIAG=0: Only modem mode. AT^U2DIAG=255: Modem + CD-ROM + Card Reader. AT^SYSCFG: Sets the preferred network technology. AT^SYSCFG=2,2,3FFFFFFF,2,4: Sets preference to 3G/WCDMA.

AT^CARDLOCK="unlock_code": Manually enters the unlock code generated by your IMEI to remove the SIM lock. Essential ZTE Commands

ZTE devices use a different set of command protocols, often focusing on encryption status and network selection. AT+ZCDRUN=8: Disables the virtual CD-ROM. AT+ZCDRUN=9: Enables the virtual CD-ROM. AT+ZSEC?: Checks the security/SIM lock status. Response 2: Network Locked. Response 3: Unlocked. +ZNCK="unlock_code": Command to enter your unlock code. AT+ZSNT: Changes the network mode. AT+ZSNT=1,0,0: 2G only. AT+ZSNT=2,0,0: 3G only. AT+ZSNT=0,0,0: Automatic mode. General Utility Commands

These standard AT commands work across almost all cellular modems supported by DC-Unlocker.

ATE: Configures command echoing (useful for seeing what you are typing).

AT+RESTORE: Restores the module to factory default settings. AT+GSLP: Puts the modem into deep-sleep mode to save power.

AT+ZRSSI: Reports current signal strength, including RSSI and RSCP values. How to Send Commands in DC-Unlocker

Launch the DC-Unlocker client and click the Detect (magnifying glass) button.

Once detected, you will see a white terminal window at the bottom of the interface. Type your command in the terminal and press Enter.

The software will return OK if the command was successful or ERROR if the device did not recognize it.
