How can I regain access to my iPhone being mirrored?

Mirroring the IMEI number of a phone is no longer a thing. It used to be called cloning and the cell providers have long ago put a stop to it. If you think your IMEI has been mirrored, contact your cell provider for additional information and help securing your account.

There is no access to your phone through the IMEI number. If you have some specific information or can provide a screenshot of something that concerns you, please update with that information.

If your ex knows your Apple Account password, then it is possible your account has been compromised. That would only give them access to the iCloud website, not direct access to your device. If you think that is a possibility , then change your Apple Account password now.

What makes you think that? Your iPhone being remotely accessed is nearly impossible without jail breaking your iPhone, which is a very extensive and expensive procedure to bypass your iPhone's security and limitations in place, unlikely your ex did that.

But your ex could access your content, not control, if you guys shared an Apple Account. If so I suggest you either take control or create a new one. To take control change the passcode and remove any foreign devices and numbers.

Facebook uses their own two factor authentication that would alert him of a password change. You would need to check with Meta or your Facebook account for options on changing the number used for two factor authentication. Do that along with changing your Facebook password is the only way your account will be secured. This has nothing to do with your device and the same thing would happen no matter what device you used to access your account.

For your Apple Account, it uses a different two factor authentication where you will also need to review the Trusted Phone numbers used on your account. On your device, there are 2 things to do immediately:

• Review your Trusted Phone Numbers - Go to Settings > [name on top] > Sign-In & Security (or Password & Security) > Two-Factor Authentication, and under Trusted Phone Numbers, make sure those are yours. If there are any you do not recognize, then tap Edit and remove them.
• Review Devices logged into your Account - Go to Settings > [name on top], and scroll to the bottom to view the devices signed into your Account. If you do not recognize a device, then tap on it and choose the Remove Device option. After that change your Apple Account Password again, and if his number was not listed as a Trusted Device, he will not be able to sign back into your account.

You can also run Security Check on your device to review information that you are sharing, It can also be used to review the Trusted Numbers and devices logged into your account. This is what you should review with Security Check:

• Check whom you’re sharing information with
• Review Trusted Phone numbers
• Review and change devices connected to your Apple Account
• Reset system privacy permissions for apps
• Change your iPhone passcode
• Change your Apple Account password

Change your passwords to all of the email addresses you use in you Apple ID, then change your Apple ID password. If you have an associated phone number, you probably need to log into your service provider account and remove any access and/or change the password for that account as well.

There are people sharing their Apple ID Passwords, or letting their significant others have access to other accounts that would unfortunately allow someone who is savvy/nefarious enough to figure out how to get the OP's Apple ID PW. Also - depending on how the OP used the phone, if they ever allow the other person to use the device and weren't present, it's possible that the other person went into settings or the Password App and simple located the OP's Apple ID PW.

It's not rocket surgery, but I appreciate to an Apple loyalist and a tech savvy person, the means by which someone might have access to another person's device, are not within the standard security protocols and use case scenarios.

Ikrupp is 100% correct. If people are sharing passwords or accounts which Apple has strongly advised against doing so for many years, then it isn't Apple's problem and they can't do anything about it.

Perhaps the OP meant that the ex used the IMEI or IMEI2 to set up a second device altogether? I think that lay people, myself included, oft use terms like "mirror" incorreclty until we know what its actually, technical term means. I have no idea what what half of the words in Community mean which makes the advice unhelpful. You gave great advice, but TBF I find myself searching non-Apple Community forums and teaching this stuff to myself for all of the reasons stated herein.

The OP asked how he could regain access to his iPhone, which suggests to me he lost all access to his phone such that it was more than just "mirroring" because when I use that feature for its intended purpose - as you and anyone who uses mirroring between devices knows - you simply end the mirroring from the iPhone.

And how is that Apple’s problem?
