Invalid phone number error while creating Apple ID

Hi davit999,

Congratulations on your new iPhone. For help with creating an Apple ID, check the steps below found in the article here: How to create a new Apple ID

"Create your Apple ID using the App Store on your device

1. Open the App Store and tap the sign-in button .
2. Tap Create New Apple ID. If you don't see this option, make sure that you're signed out of iCloud.
3. 
4. Follow the onscreen steps to provide an email address, create a strong password, and set your device region. The email address that you provide will be your new Apple ID.*
5. Enter your credit card and billing information, then tap Next. You can also choose None. Learn what to do if None isn't showing or you can't select it. You won't be charged until you make a purchase. 
6. Confirm your phone number. This can help to verify your identity and recover your account if needed. Tap Next.
7. Check your email for a verification email from Apple and verify your email address.

After you verify your email address, you can use your Apple ID to sign in to the iTunes Store, App Store, and other Apple services such as iCloud.

* In China mainland, you might be required to provide a +86 phone number for your Apple ID. You can change the number later, or change your country or region to a location that doesn't require it. This number is only used for verification purposes."

If you continue to have an issue you can test creating the account on a different device. Should the issue remain, reach out to Apple Support directly to further assist.
