cant send MMS?

[g916]

last night I was looking around the forums and there doesnt seem to be an answer that works for me.
I installed the native MMS to enable the MMS on my 2g iphone and then i installed the MMS and Tethering settings 5.6 from sinfuliphone or whatever that repo is called and it changed my APNs to epc.tmobile.com

before i was getting a message saying there was a pic resolution and size restriction and after i did that it went away and i could recieve pics again but now i cant send them!

does anyone know what to do? im lost lol
