Hello @Dinarte and welcome to the Community.
Bitdefender Internet Security cannot be installed on mobile devices, since this license covers only Windows OS. You can install protection on up to 3 Windows devices in this case.
The solution here would be to get in touch with the Bitdefender commercial support representatives to request an upgrade of your license to Total Security, as this package offers complete protection for Windows, macOS, Android and iOS under the same roof.
Simply choose one of the contact channels available here to submit your request:

Kindly be advised that some validity adjustments might be required when upgrading to a superior product. Otherwise, the upgrade is free of charge and this way you won't have to place a new separate order for Mobile Security for Android.
Let us know how it goes.
Regards,
Alex
