Getting stuck in updating my phone number for my Apple account
Hi everybody,
I've just logged in to my Apple ID to update some information. At the section of filling my phone number and area code, but the web didn't let me save it. As my example, I'm from Vietnam so my area code suppose to be +84 but I just can fill "84" in the box, then i put this area code in front of my phone number so it become "84971xxxxxx". I thought I did not follow the rule of filling these information, however the web didn't have the instruction for me as well.
I post this question to ask everyone for helping me figure out this problem. Thank you in advance and I look forward to hearing from you guys soon.
Daniel.
