I was able to send/receive MMS b4 when I was on custom rom (AOKP 4.2.2). When i updated to android 4.4 rootedi found out MMS is broken. I tried usng the same APN settings whne i was on AOKP 4.2.2 but still dones't work. Any1 know how to fix this?
I thoght it was the 4.4 so i rrestored back to AOKP 4.2.2 and i found out it stopped working too. i'm thinking it's something to do with the radio that was included in the 4.4 update that is causing this.
Are you using Google Hangouts as your default SMS app? if so, there is a known issue where the Hangouts app was not using the correct APN information and thus MMS was failing.
There is a new Hangouts version being pushed to users since a day or two ago that corrects this issue. It is slowly rolling out to all users. Check your Play Store account for an update, it might be waiting for you.
If you are not using Hangouts, please let us know.
