Quectel Ec25 Change Imei Access

AT The module should reply:

OK Try:

AT+EGMR=1,10,"350123456789012" Or

AT+CFUN=1,1 Or power-cycle the module physically.

Make a note of this number. You may need to restore it later. Some EC25 modules ship with IMEI write-protection enabled. To disable it temporarily, you may need the "IMEI unlock password" from Quectel (usually available only to verified OEM customers). However, for most standard EC25 modules: quectel ec25 change imei

AT+CGSN=1 Example output:

Soft reset:

AT+CGSN=1 The output should now display your new IMEI. The AT+EGMR command writes to the NV memory, so the change should survive factory resets ( AT&F ) or firmware upgrades. However, if you ever send AT+QPRTPARA=3 followed by AT+QURIPARA=3 , the IMEI will revert to the original masked ROM value.
