Can't receive pictures on messages

[1814]

My wifes Moto G6 messages won't receive pictures? Blue dot keeps circling instead of showing pictures. She used to receive pictures, not sure what has happened. Any advise?

Check the APN settings in Mobile Data. They have to match her carrier's APN settings.

Also, make sure her mobile data is turned on in the first place.
