pixeldust99 Very tricky issue to track down, but basically: wifi calling works for making and receiving calls certain group SMS and MMS will not send when wifi calling is enabled a simple SMS to a single recipient will work most of the time disabling wifi calling will allow the pending messages to be sent I do not see any network traffic associated with the attempted sends that don't work - it's like the phone has decided not to use the wifi to try to send it, but doesn't fall back to radio either.... so it's just stuck. I know this because SMS/MMS over radio works fine
5rlyn "Tricky" is right. I experience this too, sometimes it fights through, other times I have to play with my WiFi connection in order to get MMS to send. Who's your carrier? According to Mint Mobile, this is expected and nothing can be done.
pixeldust99 To mention a point I failed to mention above, the behavior seems to be specific to my home network
