    Hi @Toseef Ahmad ,

    I understand that you are trying to create a new account at dev.azure.com and are receiving the error, "We’re unable to validate your phone number." There are a few issues that can trigger that error, so here are some troubleshooting steps to check:

    1. Confirm that you are using a valid phone number and not a VoiP.
    2. Check that your phone can receive calls or SMS messages from a United States-based telephone number.
    3. Ensure that you have included the country code.
    4. If your phone doesn't receive text messages (SMS), try the Call me option.

    If your phone number does not meet these requirements, you can use another phone number to sign up.

    If you still face any issues after confirming these steps, kindly let me know and provide details about your region/location.

    All these facing this issue should raise it towards their cellular service provider as this seems that cellular service provider is putting the MS Authentication call on the Grey Channel and you are no receiving it.

    Always the best approach is to use Microsoft Authenticator App, to setup the app visit aka.ms/mfasetup
