MMS (send & recieve) stopped working last month on Moto X I'm trying to debug an issue with my wife's Moto X: 
she sends/receives SMS (individual texts) just fine, but MMS (photos &amp; group texts) fail to send or receive. 

Details


Moto X (v1) running 4.4.4
Used to work, and stopped sometime in November
I've tried switching from Messaging to Messenger to see if it was related to the client app and it made no difference, so I assume the problem is 


Any ideas for what to try next? Have you heard of this before? I Googled a bit but couldn't find something quite like this.

Thanks!
Aha! 

I just saw the answer to this question and it turns out to be the same thing. Somehow she (or our daughter) turned off her Mobile Data. Turning it on fixed the problem!
