I have a big problem. I bought SAMSUNG GALAXY S4 SPH-L720 from my friend. I'm living in Europe so i unlock the phone. Everything worksHSPA+, calls, texts, outgoing MMS, its ok but Incoming MMS is not!! I can send MMS, but I cannot receive MMS. When someone send mms to me nothing happen. I dont even have a notification about MMS.
I have the correct APN, i checked this with two others cariers and the problem is still the same. I'm on stock sprint rom 4.4.2. It's about security or something?
