Quectel Change Imei 〈ORIGINAL · 2025〉

Low-cost IoT modules using MediaTek or Unisoc (Spreadtrum) architectures handle identity data differently. They often require specialized flash tools provided under NDA to distributors, which can rewrite the calibration sector containing the IMEI. 4. Troubleshooting Common Failures

This article is based on reverse-engineered public documentation and developer forums. Quectel does not endorse end-user IMEI modification. Use at your own risk.

Often, issues arise not from the IMEI, but from incorrect Access Point Names (APN). Use AT+CGDCONT to configure the correct APN for your provider.

For most users, the safest approach is to keep the factory‑assigned IMEI and address connectivity issues through proper carrier agreements and module configuration. If you require additional assistance, the Quectel forums and official technical support channels remain the best resources for module‑specific questions. quectel change imei

The feature utilizes specific to interface with the modem's non-volatile memory.

During development, carriers require specific IMEI ranges for testing. Changing an evaluation module’s IMEI to a pre-approved test IMEI can speed up certification.

Send the AT+EGMR command with the desired 15-digit number. Low-cost IoT modules using MediaTek or Unisoc (Spreadtrum)

Standard AT commands ( AT+... ) are used for network communication. However, proprietary AT commands exist for engineering and calibration.

This method can permanently brick the module if the checksum or ESN (Electronic Serial Number) mismatches. It also voids warranty.

For engineers and developers working with Quectel modules, the safest and most professional approach is to respect the factory-programmed IMEI as an immutable hardware identifier and seek manufacturer support for any compliance or repair needs.

To send these commands, you must connect to the module's using a serial communication tool like PuTTY, MobaXterm, or Quectel's proprietary tools.

AT+EGMR=1,7,"<your_new_15_digit_IMEI>"

This is the most critical section.

Violations result in . These offences are cognisable and non-bailable under Section 42(7). The Telecommunications (Telecom Cyber Security) Rules, 2024 also prohibit altering IMEIs or producing equipment where IMEIs can be configured or changed.
