SMS two step verification is not working

Hi there,

I have a Windows notebook and I am trying to connect to my icloud email account. Since iCloud and Mozilla Thunderbird are not working together I am trying to connect using my Opera browser. All is fine until I am supposed to receive a SMS with a confirmation code. Guess what. After waiting 11 hours I have still not received a SMS with a confirmation code from Apple or from iCloud.

Does my phone work? Yes. Adobe also has this option and it works, from time to time, but at least they have the decency to offer to send the code via email. Which Apple does not have.

Also today I paid my monthly subscription for some applications and I bought something via internet and my card has a 3D secure authorization code also sent by SMS on my phone. Lucky me I did not have to wait 11 hours.

Please advise.

Sebastian
