I am using a Samsung Galaxy S4 SGH-M919 (originally T-Mobile) now on Net10 AT&T towers. I am having this same problem. I can receive and send SMS, browse the internet, and I can send MMS, but I cannot receive MMS. I have been using NET10 for about 3 months and MMS worked most of the time. I noticed that the problem started when I changed my plan from their $40 to $50 plan (because the $50 plan has LTE and the $40 is only HSPA so they use different APN). I have tried all the different bits of advice mentioned in this thread but with no luck. Spent a few hours on the phone over several days with Net10 support and finally they said they could not guarantee that every feature works as expected on their service.
FYI, my wife uses StraightTalk and when I insert her SIM with the same APN, everything works.
Any further help would be greatly appreciated. I thought maybe some of the info I submitted might help others figure this problem out.
