Put the phone number in front of a domain for each carrier, a list is here.

There are several international lists too, here's a couple:

Do they work? For Portugal it still lists Telecel - which hasn't existed since '99.

My list is accurate as of a year or so ago, or at least they don't bounce back when you send an email to them.

Thanks, this hack (if it's a hack) looks interesting.

It works, but know that it is nowhere as reliable as an SMS sent through a carrier's gateway.
