Sprint Galax Note3 and Mega - no Data - any clues?

[jacksonii]

I have us cellular note 3. I flashed to pageplus but when I put the sim in, I have nothing. When I take the sim out I only have talk and text. I have all my keys and prl. Can you tell me what Im doing wrong or not doing? Im on stock 4.4.2. I have flashed us cellular note 2's over with no problem. I have no idea what to do at this point, I am stuck. Any help would be greatly appreciated.
