Outgoing texting not working after changing carrier on Samsung Galaxy S4

I changed carriers from Verizon to AT&T on my Samsung Galaxy S4 Sch-I545 phone. Everything works fine except I cannot text out. I receive texts but cannot respond or initiate outbound texts; neither individual nor group texting works. My phone does not have a "Message Center" option in the Message Settings section so I cannot input the AT&T phone number here, which I understand can fix this problem when available as an option. I later switched to T Mobile to see if this fixed the problem. It did not. Any solutions?

Welcome to Android Central!
Try to contact your carrier. It's their job,don't be afraid to call them,you pay them.
