Hello doom__1,
Thank you for using the Apple Support Communities. I'd want to make sure I was able to use my Apple Music subscription as well. I understand you've canceled your pre-existing subscription, and you want to use the bundled Apple Music offered by your carrier.
When you say it won't link your Apple ID, can you provide some detail about this? What exact message are you seeing?
This link, titled About bundling Apple Music through mobile phone service providers, has a few suggestions that might be a good starting point:
- If you signed up for Apple Music through both your mobile phone service provider and Apple, cancel one of your subscriptions. You can cancel your subscription through Apple on your iPhone or on your Android phone. If you want to cancel your bundled Apple Music subscription, contact your mobile phone service provider.
- If you can't verify your subscription, make sure that you're connected to the Internet. If you're using cellular data on your iPhone or iPad, make sure that Cellular Data is turned on in Settings > Cellular. You might also see a message asking you to verify your subscription if you're signed up through both Apple and your mobile phone service provider.
- If you see a message that says your phone number can't be verified, follow these steps:
- On your iPhone or iPad: Go to Settings > Phone > My Number. If your mobile phone number isn't correct, enter the correct number, then tap Save.
- On your Android device: Make sure that you have the latest version of the Apple Music app. Then, close the app and go to Settings > Apps > Apple Music > Permissions and turn off the Phone permission. Reopen Apple Music, and when asked about SIM permissions, allow it. Deny the second message about Phone permissions, and enter your correct mobile phone number manually."
I hope that is helpful. Have a good day.
