With the advent of being able to port your phone number, there's no way to know what the carrier is by phone number!
No need to know the carrier. Send the email to the cell phone's number @teleflip.com like this: email@example.com
or this: firstname.lastname@example.org
I think this only works for US Providers, but check http://www.teleflip.com/
for more info.
