– Switch to SIM-level identity (IMSI) rather than IMEI-based filtering. Carriers can configure this.
Testing how private LTE/5G networks handle specific device profiles, blocking rules, and identity white-lists.
On many Quectel modules (EC25, EG95, etc.), the command syntax is:
Understanding the, legal, technical, and practical aspects of changing the IMEI (International Mobile Equipment Identity) on Quectel modules is complex. The IMEI is a unique identifier for a cellular device, and changing it is often illegal and violates network policies. quectel change imei
Once the module reconnects, open the terminal session again and verify that the changes successfully registered: AT+GSN Use code with caution. The terminal should now display the new 15-digit sequence. Troubleshooting Common Errors 1. Error Response: "ERROR" or "+CME ERROR: 58"
Connect to the module's AT port at the correct baud rate (usually 115200). Enter AT to confirm the connection (should return OK ). Execute the command: AT+EGMR=1,7,"123456789012345" If successful, the module returns OK .
Often, attempts to change IMEI through AT commands only work under specific, controlled scenarios, such as when the module is not actively connected to a WAN network. 3. Legal and Regulatory Warnings – Switch to SIM-level identity (IMSI) rather than

While changing an IMEI is a powerful tool for hardware developers, it is a highly restricted activity globally. Understanding the legal landscape is mandatory for any engineer or business. Local Laws and Regulations
For the changes to commit and register on the cellular baseband, cycle the power or issue a soft reset command: AT+CFUN=1,1 Use code with caution. 3. Hardware-Specific Considerations
These modules are different. They do not support AT+EGMR .
To communicate with Quectel modules, you use a series of (Hayes command set) sent via a serial port (UART or USB AT Port). 1.1. Querying the Current IMEI
