old phone number deactivated

Hello there AhmedOlsa,

It looks like you came to us from Restore your iPhone, iPad, or iPod touch from a backup - Apple Support, which you'll absolutely need when we get the situation with your phone number resolved. Let's get started!

We'll need to use Manage two-factor authentication for your Apple ID from iPhone - Apple Support, which states to update the trusted number, we'll need to do the following:

"Add or remove a trusted phone number

When you enrolled in two-factor authentication, you had to verify one trusted phone number. You should also consider adding other phone numbers you can access, such as a home phone, or a number used by a family member or close friend.

1. Go to Settings  > [your name] > Password & Security.
2. Tap Edit (above the list of trusted phone numbers), then do one of the following:

• Add a number: Tap Add a Trusted Phone Number.
• Remove a number: Tap  next to the phone number."

If you're using a different device, let us know so that we can provide accurate steps moving forward.

After updating the phone number:

"Trusted phone numbers don’t automatically receive verification codes. If you can’t access any trusted devices when setting up a new device for two-factor authentication, tap “Didn’t get a verification code?” on the new device, then choose one of your trusted phone numbers to receive the verification code."

Let us know if you're able to complete those steps. If not, let us know what happens. If you get an error, we'll need to know the exact error you receive, since it provides valuable information that we'll need for troubleshooting.

Have a lovely day!
