    I own 2 ATT lumia 1520s, a green one that works perfectly running 8.1 and a red one with a few hardware issues that I use to test windows 10 builds. I tried switching my sim to the red one earlier and everything seemed to work fine, except for mms. I noticed that the apn settings form changed and was wondering if anybody on straight talk had figured out something that worked for them.

    these are the settings I have used for several years on various phones with ST AT&T SIM. Currently using these on my 930 running build 10166 of W10TP. I don't know if it actually makes a difference, but I had to change the IP type in data apn to IPV4v6 to match the mms apn. Also, it took about 20 minutes for the mms to kick in after I input the apns and restarted. Good luck.

    EDIT...you have to hit the "save" button for each apn then when you back out, hit the details

    button and hit apply(sorry if you know this already)

    Thanks I will give these settings a go.

    EDIT
    It turns out that I had the right settings to begin with, I just hadn't waited long enough.

    That's great! It's weird with ST(which I've used for almost 5 years). Sometimes the mms kicks in immediately and sometimes takes hours.
