Answer 1

Our system has detected that you have attempted to associated multiple phone numbers for this request. We actively monitor and act against suspicious activities to protect customers and Microsoft platforms from fraud, account compromises, and other malicious activities. Our actions vary from preventing users from joining our program to disabling subscriptions. In this case, the use of multiple phone numbers has invalidated your request.

If you believe you are using a valid phone, here are some troubleshooting steps that you can try to resolve this error:

1. Make sure that you are using an actual cell phone, not a Google voice or Twilio number.
2. Make sure that you are including the country code, since it's not always included by default. If your local mobile has a 0 at the start of it, you need to make sure it's included as well.
3. Note that if you had a M365 developer subscription in the past you must wait 60 days before you can open a new one with the same phone number/email account.
4. If you have tried all of these steps and still face this problem, you may need to create a ticket on the subscription support webpage.
