Update an Apple Account trusted phone number before changing SIMs

A trusted phone number can receive Apple Account verification codes and support account recovery. People often remember this only after abandoning an old SIM, moving countries or losing a phone. Update the number while you still have a trusted device and access to the old route. Apple distinguishes trusted numbers from trusted devices; neither should be treated as a substitute for the other.

Before you start​

Make sure the new number can receive messages or calls and is under your control. Keep the old SIM active until the new number is verified. Check whether a family or employer controls the new line; a number that can be reassigned unexpectedly is a poor long-term recovery method.

Do it step by step​

1. On a trusted iPhone, open Settings, tap your name, Sign-In & Security, then Two-Factor Authentication or Account Security as shown. Find Trusted Phone Numbers. Apple also documents account.apple.com for web changes.
2. Add the new number and select the available verification method. Enter the code delivered to that number. Do not provide this code to someone who calls claiming to be Apple or a mobile carrier.
3. Confirm the new number appears in the account's trusted-number list. Check that your trusted Apple devices remain signed in and able to display verification prompts.
4. Only after confirmation, remove an obsolete number that you no longer control. Leaving a recycled number on the account can send security codes to a stranger; removing the only working number prematurely can block you.
5. Test a normal account security view from a device you already own, without repeatedly signing out of everything. Record official recovery steps in a safe place before travel or device replacement.
6. If your phone was stolen or the old number was compromised, contact the carrier through a verified channel, secure your Apple Account and inspect its signed-in devices. Changing a trusted number alone does not undo an active unauthorized session.

Check the result​

The new number is verified and listed, the obsolete one is removed when appropriate, and a trusted device still works. You can receive the next code without relying on a disconnected SIM.

If something goes wrong​

If you cannot reach any trusted number, follow Apple's account recovery process from its official website or support instructions. A caller offering to bypass the waiting period or requesting the code is a red flag.

Know the limit​

Phone numbers can be reassigned or taken over through carrier fraud, so do not rely on one number as the only recovery path. Account recovery timing and controls may differ if a recovery key is enabled. Keep multiple independent, controlled routes where Apple permits. Apple trusted phone numbers
