The error "bad phone number" during registration could be due to several factors related to the phone number management in Austria. Here are some potential reasons:
- Phone Number Type: Ensure that the phone number being used is of a supported type. In Austria, both Toll-Free and Local numbers are generally available for receiving calls, but they may have restrictions on sending SMS.
- Subscription Eligibility: The customer must be on a paid Azure subscription to acquire a phone number. Phone numbers cannot be registered using Azure free credits, and the availability of numbers is dependent on the Azure subscription billing location.
- Format of the Phone Number: Make sure that the phone number is entered in the correct format, including the country code if necessary. Incorrect formatting can lead to errors during registration.
- Regulatory Restrictions: There may be regulatory reasons affecting the availability of certain phone numbers. If the number is not eligible for use in the Azure system, it could result in a registration error.
If these factors do not resolve the issue, consider reaching out to Microsoft support for further assistance.
