So it's an Android VM that can be accessed from a browser for $15/month. For an extra $10/month you can attach a phone number to it that has free incoming calls and SMS along with pay-per minute outgoing calls and pay-per message SMS.

I see App Lounge in the screenshot so I assume the VM's are running /e/. Have you tried installing any of the MDM's out there like AirWatch or InTune?

As a thought exercise, how about some light abuse. What would happen if I rammed a couple TB of BitTorrent data through that VM. Maybe used it as seedbox. Or maybe a proxy so I can access a streaming service.

It feels like you're really trying to sell the phone part, and that the Android VM is a means to an end. However, this is just a random phone number that I suspect isn't portable. So if I stop using your service I can't take the number with me. So why wouldn't I get a Skype number for $6.50/month, Skype to Phone for $3.50/month, and then use the web.skype.com page to make all the phone calls I want. Or you can do what I do and use jmp.chat for phone calls and SMS and have it all routed to the XMPP client of your choice (as long as that client supports all the needed features).
