Cannot send/receive pictures in messaging

[smg1062]

For the past three days or so, I have been unable to send/receive pictures (MMS). I checked and changed all settings back & forth, even switched to Hangouts from Chomp with no luck, so I'm guessing its NOT an app issue.
I have a Nexus 5, if that matters.............

Can anyone help???

Did you check your APN settings?

Try using textra messaging app from the play store. It worked for me using an LG g2 that wouldn't send or receive mms
