Managed Google Play Android enrollment​ by intune.microsoft.com

Hello,

We are trying to create an admin account through the Microsoft (itune) "enrollment android device" platform. We create our profile and in the last step a page with the following text appears

"We've detected unusual activity on the account you're trying to access. Follow the instructions below to continue".

And this is where the trouble begins:

We tried different phone numbers of our colleagues, got a new sim card and always the same message

"This phone number has already been used too many times for verification"

How is it possible to use a sim card with a brand-new number or a card of people who have a one google registration. (for example my grandmother :D) Nothing works!

We also created different emails with our domain through Microsoft admin center, always the result is the same:

"We've detected unusual activity on the account you're trying to access. Follow the instructions below to continue".

Enter the phone number:

"This phone number has already been used too many times for verification"

Please, please help solve this problem :).
