After updating to 5.1 I lost contacts and no mms

Got an ATT moto x 2013. After updating to 5.1 I lost about 90% of my contacts, and I can no longer send picture texts. Any help appreciated.

Just did this and all is fixed, thanks to stevenryannn


Settings>More>Cellular Networks>Access point names...

Tap the three dots in the top right corner. Select "Reset to default".

This fixed it for me.
Good luck!

I had the same problem with MMS. Does your fix above change anything else?
