Can’t get in my iCloud account

Hey eze813

If we understand correctly, you're trying to use account recovery to regain access to your Apple ID account, but don't remember the trusted phone number on file. If that's correct, you do need to at least know the phone number to start the process. Have you been able to check with family, friends, and your carrier at that time? Just in case, here's more information about account recovery: How to use account recovery when you can’t reset your Apple ID password - Apple Support

Thanks for using Apple Support Communities.

Take care!

The line is disconnected , you can switch to new cellular service , using the same mobile number , however number is always with first cellular service centre .

Using the same number the new cellular services will give their services to you they will issue a new sim , the account is still active on the iCloud server .

in case if the actual owner ( your moms friend contact apple support senior care advisors Contact Apple for support and service - Apple Support ) if credit card was added in the account and its details are known to her , the account can be verified within moments and opened by them .

Your friends mom has to visit cellular service centre , the number can be obtained from them it depends is the trusted number still active , the Apple ID and its password is remembered see threads iCloud verification - Apple Community

Hi eze813,

When an iPhone is given away, it needs to be erased with the Apple ID signed out and Find My disabled. This info is found here:

What to do before you sell, give away, or trade in your iPhone or iPad - Apple Support

Since those steps were not followed, this means the iPhone is Activation Locked. This is a security feature, and can not be removed by you or Apple.

If your friend's mom still has the proof of purchase receipt for that iPhone, they can use the Account Recovery process which we talked about in our last message.

Otherwise, you can recycle the iPhone:

All the best.
