I have the same issue
What is the correct PH Number Format for Text/Call identity verification when signing-up on Azure?
I am trying to sign-up to Azure but I keep getting this error when trying to verify my identity using Text/Call - "We’re unable to validate your phone number".
I've tried a number of formats:
9XX XXX XXXX
09XX XXX XXXX
639XX XXX XXXX
XX 9XX XXX XXXX (leading XX is area code)
What format is it expecting for a Philippine phone number and how do I get past this error?
I found some workarounds that says to use the "Use a different phone number to verify your identity" option, but that didn't work too.
I noticed a "Identity Verification by Card" option at the bottom of the form, but clicking it does not seem to do anything.
