Lost Cellular Data after teardown.

I managed to replace my glass (not digitizer) after dropping my Moto X. Upon reassembly, everything works except I can't get any data service (no 3G or 4G, etc.) Voice/Text work just fine and signals are stong, so it seems my antenna is connected. I've done a partial disassembly again but can't see any ribbons/connectors that are off or broken. Does anyone know what else to check to see if I can get my data service working again? Thanks!
