Receiving mms but not sending

[laidback1]

I have a Evo 4g flashed to Page Plus and running ver 2.3.3 recently I noticed that although I receive mms just fine and phone indicates that it is sending mms they are not being received.
I've checked all I know (limited) to check and all seems to be correct.
Any help will be appreciated

Sounds like an incorrect flash. Do you have any other issues besides MMS?

None worked perfect for over a year until about a month ago!
Tried to think of any "changes" nothing other than apps.

So, MMS worked for a year but now it doesn't? You should go back and delete the most recent apps over the past month you have downloaded and try again

Not familiar with Page Plus but there is a fix for EVOs flashed to Boost

No recent software updates or security updates of any kind?

None! everythings perfect including receiving mms
