account details unavailable

I also had this problem and it was fixed when I went into my settings and turned on the "data" on the settings. I went in to settings --> cellular --> scroll down to "settings" amongst the list of apps and turn on the data. Voila problem fixed!

i was have the same problem but fix it. just go to setting >> general >> rest>> rest setting (only) and this problem will disappear . but u have to reorganized yr setting from the beginning

I have same problem on iPhone 4S. IOS 9.1

When i go to Setting/iCloud and I tap my name/apple ID, I am prompted to 'Sign in to iCloud"

(Enter the password for your Apple ID). when I put in my password the error message comes up showing

"Verification failed

An unknown error has occurred"

Sometimes it comes up with what asiriwadhna experienced.

I have changed my password all to no avail. Whats more confusing is I am able to log into iTunes/App store.

My iCloud email is my primary mail and I could not access it since all this started, so i had to use security questions when changing passwords.

Need help ASAP.

It didn't help me 😟 I'm desperate!

I've done everything but that 'AccountDetails Unavailable' message keeps showing

I Also get this msg. It happens either because I enabled two step verification or I put my email in a second iPad. My device has no cellular connection. i just hit ok and dismiss it..

Thank you - this worked for me! 🙂

I could not get as far as the verification code step.

For me it seemed that although I'd inserted a SIM and the carrier was showing correctly, the carrier had not set up the plan as yet and I was not getting mobile data. (wifi off)

I'm not sure if it needs wifi as I'd skipped wifi setup - as soon as I did hook up to wifi though I could sign in to iCloud and shortly after I got a few texts from the 3/4G carrier saying the service was being set up and to restart the phone.
