I don't have any SIM card (in the past I had, and used it on iTunesConnect) and I just found that when I tried to log in, the SMS verification page popped up and forced me to enter the verification.
I deactivated the phone number so I clicked the cannot access to it button. Then I entered the phone number that I used to use, and then the page moved to another one describing that I must add another phone number on iPhone and Mac by going to the Settings - Name - Password and Security (the exact name might be different as I don't set English).
However, adding another number also forces me to get the SMS verification done...
In this case is there any way to use the iTunesConnect without the phone number?
