I've moved recently from country A to B. Unfortunately I cannot login anymore to my Azure account. I have a personal account not an organizational account.
I've followed all steps here 
I cannot open an Azure support ticket as I cannot login anymore.
How can I add my new mobile number so that I can get a code to login to Azure in such a case?
