Is it possible to find out by phone number whether a subscriber is online without dialing it?
Perhaps there are some protocols or api, for example, send SMS and see the delivery report or mms or something else? or there are services that provide it.

For example, smsc.ru/api/http/#send , ping parameter. Or extended information - smsc.ru/api/http/#hlr.
