How do I disable two factor authentication for my Apple ID because I'm not using my SIM card anymore?

Hello,

I see you want to disable two-factor authentication. For some background I suggest you read the support article: "Two-factor authentication for Apple ID" - Two-factor authentication for Apple ID - Apple Support

When reading that article some people (including some providing advice on this forum who miss the part about some people being able to disable the feature and just say you cannot) have difficulty determining if a person can or cannot disable two factor authentication on their accounts. Here's the actual situation:

Several years ago Apple transitioned to using two-factor authentication for additional account security. Accounts created since that time automatically use two-factor authentication and this indeed cannot be disabled.

Some people have older accounts from before two-factor authentication was mandatory on new accounts. Apple encourages those users to transition to two-factor authentication when signing in on their accounts because without it "your account is less secure and you can't use features that require a higher level of security." However, the support article also says in tiny, light-grey font: "If you updated to two-factor authentication inadvertently, you can turn it off within two weeks of enrollment." In other words if you have an older account, recently activated two factor authentication ("inadvertently" or not), and you're within the two week period for turning it off again, you should check for an email from Apple for a way to do this. If you don't see one about this, look in your junk mail folder.

If you can still sign into your account on another device you can investigate adding more ways to get a code such as multiple telephone numbers where you can receive a text or a phone call. This is based on the section "About trusted phone numbers and trusted devices" in the article: Two-factor authentication for Apple ID - Apple Support

To see, add, or change your trusted phone numbers use one of these methods:

● On your iPhone, iPad, or iPod touch: Go to Settings > your name > Password & Security. Next to Trusted Phone Number, tap Edit.

● On a Mac computer choose Apple menu  > System Settings (or System Preferences), then click your name (or Apple ID). Click Password & Security, then add or remove a trusted phone number.

● Using a web browser:

1) Go to https://appleid.apple.com and sign in.

2) Follow security options until you find one letting you change trusted numbers,

3) Click "+" to add a new number (you may be required to verify this number).

4) If you wish to remove an old number, click "-" next to the number.

If you had set up an Account Recovery Contact ( Set up an account recovery contact - Apple Support ) you can also get a code that way.

If you can’t sign in, access a trusted device, reset your password, or receive verification codes, you can request account recovery to regain access to your account.

You should consider making sure you have multiple trusted devices and telephone numbers (ask a friend or a relative).
