New iphone stay in a loop when entering apple password

Hi lubnamazin,

It sounds like you're running into an issue with trying to sign into your Apple ID on your new iPhone, is that right? We want to make sure you're able to fully enjoy your new iPhone, and we'd love to see how we can help.

Just to make sure we're on the same page, is the issue happening when you try to complete the steps outlined under the "Sign in with your Apple ID" part of this page? Set up your iPhone, iPad, or iPod touch If so, do any error messages appear when you try to sign in?

If your device has already been set up, you can use these steps to sign into your Apple ID account: Sign in with your Apple ID

Also, to help rule out a possible connection issue, can you let us know if the issue happens when your device is connected to another network? Connect iPhone to the internet

Thanks!
