I need an Apple ID with my new cellphone number

Hello, thank you for using Howly. I’ll be happy to help you out! May I ask your name?

Nice to meet you, *****!
Do you mean you want to change your phone number in your Apple Id account?

Go to Settings > tap [your name] > Name, Phone Numbers, Email. Next to Reachable At, tap Edit.
Tap Delete next to your phone number and follow the instructions.
Let me know if any of the steps are not quite clear, I'll be happy to clarify them for you!

Thanks
