Cannot change trusted phone number on iphone 6 (IOS 12)
Hi all,
I have already changed my mobile and using right now.
But, I can't change trusted phone number with new one. I didn't get verification code for change.
Two-Step code is okay.
That's why account phone number is new one and trusted number is old. Currently I doesn't use old number.
So, how to fix this problem?
Thanks.
iPhone 6, iOS 12
