Hello!
I activate my second iPhone via my id. I enter all the data correctly, I'm sure. but another iPhone says that my id can not be used (although I confirmed that it is possible)
Your iPhone, iPad, iPod touch, Mac, PC, or Android phone automatically associate with your Apple ID and iTunes when you use certain iTunes features. After a device associates, you can use it to download and play music, movies, TV shows, etc. that you previously bought from the iTunes Store. You can also turn on Automatic Downloads on an associated device.
You can have ten devices (no more than five of them computers) associated with your Apple ID and iTunes at one time.
The list of associated devices that you can view in iTunes is not the same as the list of devices that you're currently signed in to with your Apple ID. You can check your Apple ID device list to see where you're signed in on your Apple ID account page.
You don't need to associate your devices to buy content or download new purchases. You can remove an associated device if:
- You reach your limit of associations and want to add a new one.
- You can't download past purchases from the iTunes Store.
- You want to sell or give away an associated device.
More about associated devices
Your iPhone, iPad, iPod touch, Mac, PC, or Android phone automatically associate with your Apple ID and iTunes when you:
- Sign in to Apple Music with your Apple ID.
- Download music to your iPhone, iPad, or iPod touch in the Music app to listen to when you're offline.
- Turn on iCloud Music Library.
- Download past purchases that you made in the iTunes Store, App Store, or iBooks Store.
- Turn on Automatic Downloads for iTunes Store, App Store, or iBooks Store purchases.
- Turn on Family Sharing.
- Subscribe to iTunes Match.
When you try to associate another Apple ID with a device that was already associated, you might see a message that says, "This device is associated with another Apple ID. You cannot associate this device with another Apple ID for [number] days." Depending on when you associated your device with your Apple ID, you might need to wait up to 90 days to associate the device with another Apple ID.
Let us know if this helps.
Thank you for using Apple Support Communities.
Cheers!
