So after porting over my number from Sprint yesterday and trying a variety of APN settings I am still unable to receive MMS messaging on ST's network on the Nexus 5. LTE works beautifully, I can also send MMS messages however cannot receive them, which is a big issue in my job as pictures are sent back and forth daily. I have attached my current APN setup which is one of about 5 I have tried. I have also deleted all other APN's and restarted the phone before trying to receive MMS messages again on each APN variation. I am a new customer to Straight Talk and have a new ATT LTE micro sim card.
