How to activate the account when you fail to get PIN code on AWS

I have to applause AWS team’s hospitality.

For the registration of AWS new account, everybody is requested inputting PIN code on the phone which is sent from AWS team.
But the procedure is not go well sometime(It’s because of international calling I guess)

At here, there is a one critical problem.
Unless to receive the calling AWS, doesn’t become available to use no any service related verification.


Then, how could we —uninflastructured country users— use AWS?


You just open the case Support case and request to call to yourself by AWS staffs.
I was like as below.


Me(Web): There is no calling for PIN number!!
AWS(Web): Could you let us know your phone Number? And please check your inbox.
Me(Web): Number is xx-xxxxx. (I sure that I never hear the ringing…) 

—5min later—

AWS(Call): Hello, have you checked your inbox?
Me(Call): Yes, I’m about to check it.(AWS call to me directly, how quick they are!?)
AWS(Call): Could you read the PIN number in the email which we sent?
Me(Call): It is xxxxxx. #Not normal PIN number
AWS(Call): OK, activated thank you for using AWS service. See you.
Me: Oh…how it is…


If you troubling about AWS, you should open the support case immediately.
