Push notification based on mobile number

Question

can we send notification to the device which is not having the app installed in android? Can we send notification by using the mobile number only?

Answer 1

Using Google Cloud Messaging - no.

You can send a data SMS. This type of SMS is invisible to the user but can be handled by the device to build and display a notification - it's just that the data source is not GCM but rather a plain SMS.

EDIT: Oh, nevermind, the question asks if we can do this without having your app on the device. In that case, the answer is just "no".
