Law one, we enter the official settlement
1th Step into the iphone we go into my Support profile and then we click into the Apple ID login.
Step 2nd, if we take the iphone as an example, we're going to unbind
3rd step, click the Logout button and confirm.
Step 4, and then you will find the cancellation page, as shown in the following figure
This binding cancellation is the binding of your Apple ID to your iphone, so you won't be able to use the Apple ID to download the software anymore.
Method Two, through the SIM card
The first step, we use colleagues or friends of the IPhone, first back up good.
Step two, then we install the SIM card into their phone, activate the iphone, log on to the imessage service with the phone number, and then close it.
The third step, then we remove the card from the friend's phone, and then delete all the settings and content, install a friend's SIM card, after activation to restore the previous backup.
