Did you try getting the APN Settings Shortcut app from the play market? You can go into the apn app settings and just fill in 3 things and your stock messaging mms should work. Open the apn app and press your hardkey menu button then where its says NAME put in verizon. Then where it says APN put in internet and where it says MMSC put in
http://mms.vtext.com/servlets /mms don't fill out anything else then press the save tab and reboot your phone. Then your mms should work.
