4. Having your SAM activated, access the Method section and there you have to choose By Country and Carrier option. Choose your GSM carrier on which you will be using your unlocked iPhone. Some carriers are using several ID’s for their SIM cards and, therefore, it is important to use the SIM ID function if you will be using your device on such a network operator. Otherwise, iTunes will be will not unlock your device. In some cases the Auto Detect function will work. In other cases, choosing the network operator on which your iPhone is locked, will do the job. Unfortunately, it looks like everything depends on that specific carrier.

5. In the More Information area you have to look for SAM Details and write the IMSI number in a notepad file. You can also copy it in an iOS applications, too. Then tap on the Spoof Real SIM to SAM.

To be more precise, you have to disconnect your iPhone from the computer, close iTunes, reconnect the device, open again iTunes, and your iPhone should be automatically activated.

In order to accomplish this task, you will have to access the menu which is placed in the upper part of your iTunes. There, you will find the followings: the name of the device, the iOS version, the phone number etc. Using your mouse, click on the telephone number and you will be seeing the ICCD which has been saved by iTunes. Then you have to check if the same ICCID is being written on your SIM card. If they are not the same, then this entire tutorial needs to be restarted.

8. Disconnect your device from the computer. Close iTunes and head to the SAM menu in order to de-activate it.

9. Reconnect your iPhone to the computer, open iTunes, and this application will tell you that it cannot activate your device. This error appears because you have de-activated SAM.

10. Close iTunes and open it again. Now, everything should be OK and your iPhone should already register in the new network. Unfortunately the PUSH notifications won’t work, therefore, from the SAM menu you have to choose the Clear Push option and re-connect your device to iTunes.
