I m setting up my new iphone. I do not have access to my old iphone and number.

i just received a mail in which it is said that an account recovery request is made and i will get a call after 3 days when it is ready to recover

The Account Recovery request is different and used when you cannot access your account. That process goes like this:

• After you request account recovery, you get an email with a confirmation of your request and the date and time of when you can expect to regain access. This email arrives within 72 hours.
• It may be several days or more before you can reset your password. Contacting Apple Support can’t help you shorten this time.
• When the waiting period is over, Apple will send you a text or automated phone call with instructions to regain access to your account. If you don’t receive the text or call, once the period specified in the original email is over, you can still go directly to apple.com/recover. Follow the instructions to regain access to your Apple Account.

It is also important not to do anything that will cancel the Account Recovery request:

• If you started your account recovery in Settings, System Settings, or the Apple Support app, you can continue to use that specific device during the account recovery period.
• Regardless of how you started the account recovery request, you should turn off all other devices that are currently signed in with your Apple Account until account recovery is complete. If your Apple Account is in use during your request, your account recovery will be cancelled automatically.
• If you started your account recovery request with iforgot.apple.com through your device’s browser, you should avoid using that device during this period. If possible, turn that device off. Using that device might cancel account recovery.

Changing the Trusted Phone number on your Apple Account is effective immediately. I have not experienced an email confirmation on the change.

If you think someone else has access to your account to change your Trusted Phone Numbers, then you would also want to change your Password.

When I added a Trusted Phone number to my Apple Account, I just had to enter the number and a verification text was sent to it and after I clicked the link, the number was added.

• Is there some other factors that may be causing an additional delay, like a forgotten Apple Account Password?
• Do you have access to the Trusted Phone number you added to receive the verification code?
• Did you change it from a Trusted Device or on the web?
• Was it done with one of these methods?

--- On your iPhone or iPad: Go to Settings > [your name] > Sign-In & Security > Two-Factor Authentication. Below the list of devices and phone numbers, tap Add Trusted Phone Number.

--- On your Mac: Choose Apple menu  > System Settings > [your name] > Sign-In & Security > Two-Factor Authentication. In the Trusted Phone Number section, you can add and remove phone numbers.

--- On the web: Go to account.apple.com, then click Sign-In and Security > Account Security. In the Trusted Phone Number section, you can add and remove phone numbers.

When you enter a new Trusted Number, a 6-digit TOTP code is sent either by SMS or voice (depending on your “type” selection) to the new number.

You’ll need to enter that code received at the new number back at “your location” before the new Trusted Number becomes “in-service.”

An account recovery is an entirely different beast with a significant waiting period.

Only AFTER you regain access to your account will you be able to setup updated Trusted Numbers.
