Can I send / receive MMS messages over WiFi?

Yes if your mobile carrier supports sending MMS over WiFi.

To test, please try to send an MMS using your Android stock messaging application (WiFi ON and Mobile Data OFF) and report back your findings? When doing this test check the 3G/4G data indicator does not come on during sending (indicating that your phone is turning mobile data back on).

Note: Verizon does not support MMS over WiFi. You must have Mobile Data ON to send / receive MMS. For users running firmware versions prior to Lollipop Textra can do this automatically for you (if you normally leave your data off), see Textra Settings > MMS Settings > Activate Mobile Data. For Lollipop firmware and above this setting is not present as the functionality required to do this has been removed by Google, so it's not possible.
