First I'll want to tell you that I dont have the handset. and never used any Samsung handset before.
this is for a friend of mine. and I have tried searching and giving him all the information what I could.
he had tried saving the settings sms received from Ufone twice but that didn't work.
even I have sent him the settings from samsungmobile.com but he is still not able to send/receive MMS. while I tried to send the same settings from samsungmobile.com on my own number on Nokia Handset and they were working great.
so I am just considering responses from the users of "Samsung T519(or other similar model) with Ufone MMS successfully enabled" with their experience of any issue while configuring the MMS on the hand set or may be on other Samsung Handset.
