I have a Samsung Galaxy S7 and can't send or receive pics on messenger.

[AC Question]

I can send on what's up but not on messenger or messages. I can rec/send text but not attachments.

Check the APN (in Other Networks in Settings). Make sure it matches the one your carrier uses. (Search yourcarriersname apn to find their APN settings.) With the wrong MMS settings, you won't send or receive pictures (or any files).

Welcome to Android Central! Also, do you have mobile data turned on, or are you just using wi-fi? MMS requires mobile data turned on.
