My wife and I have the same 2013 Moto X (XT1053), both on Consumer Cellular, APNs set the same and both use the paid version of Textra on which we have the same settings. We can both send and receive MMS messages but she keeps getting a text message from Textra saying "Can't get MMS - Check Textra --> MMS settings --> APN" She has probably gotten this text 6 or 7 times today already and yet she has successfully received and sent MMS messages today. I'm guessing this is either a CC or Textra problem but posted this here in case someone else might have gotten the same message and figured out how to fix it.
