Cet article explique comment changer le code IMEI de son téléphone.
C'est vraiment simple, je ne savais pas que l'on pouvait réaliser cette opération directement depuis le téléphone !

To find out IMEI number of your device, just dial #06# .
To find out device ID, Just dial ##8255##* and you will get your device id in GTalk Service Monitor. And an another way to find out device id is by going to Menu > Settings > About Phone > Status.

1. First Dial #7465625# or ##3646633##* on your android device.

2. Now, click on Connectivity option or call pad,

3. Now look for CDS information and then click on it.

4. Then, checkout for Radio information.

5. Now, if your android device is a dual sim device. Then you will get two option like IMEI_1 [SIM1] and IMEI_2 [SIM2]. Then select any one or of which you want to change IMEI number.

6. Now, change your IMEI number illustrated below,

         AT +EGMR=1,7,”IMEI_1” and “AT +EGMR=1,10,”IMEI_2”                 

7. Now, just replace IMEI1 or IMEI2 with your any your desired number. and then click on SEND.

(And...changes are visible after reboot !)
