I've built https://cophone.io - your online smartphone, complete with a phone number. It is an Android system running in the cloud that you can access via a browser, even on mobiles. Things like microphone and webcam work nicely, so you can even have meetings on cophone.
After iterating on it for a while, customers seem very happy and now growing day by day.
No marketing so far, just being out there and posting on various channels once in a while.
A small feedback: The poster image on your homepage (https://cophone.io/assets/images/virtual-smartphone-cophone....) is unnecessarily big (1.7MB). You can compress it into a much smaller JPEG without any visible defect. Maybe you don't need it at all as video will start playing soon anyway.
You mention national and international phone calls. Do these virtual devices appear local to the customers region, to where your servers are located or are there options?
Could someone use your service to run an Android device that behaves as if in the United States, for example, to use Android apps or web services that are region blocked and restrict use of VPN/Proxy?
That's great input! This is all very fresh so I'm still building connections. I have to admit Voip providers were not on my list but it totally makes sense.
a) AFAIK Canonical's Anbox does NOT give you a phone number. Also afaik, they don't provide a recent Android version, so you're stuck with a really old version.
b) This is a really good point! I don't know atm, I'll have to look into it.
Indeed, this is something that I have learned from the comments here: that cophone needs to forward the notifications from the virtual smartphone to the physical one(s). Will put it on high priority!
Think BYOD, but without mixing personal and business data. So you can just open a browser on your personal mobile phone and access your work phone. Then, when you're in front of your (work) laptop, you just open a browser tab to access the same cophone instance.
