    Just got a 950XL. Set my MMS settings like my old Lumia 1020, which was an unlocked ATT phone.

    Now I can't get MMS to send.

    I've tried multiple settings, one with ATT in the name, the other with tf-mms.

    I tried copy and paste of the information I used, but the Windows Central forum told me it was spam.

    Neither setting type works to send MMS messages. The ATT settings worked on Win Phone 8.1 on the ATT unlocked 1020. Not anymore apparently.

    Please let me know if you find a working solution. I think Straight Talk updated their settings recently. I can send and receive pictures, but GROUP TEXT does not work at least for me. Here is what i am using

    APN Settings

    MMSC http://mmsc.mobile.att.net
    MMS PROXY proxy.mobile.att.net
    MMS PORT 80
    APN TYPE default,mms,supl

    There is no "APN type" setting on the Lumia 950 /xl. Now what?

    Straight Talk Internet APN & MMS APN settings for Nokia Lumia 635 Windows 10 mobile phone with ATT SIM

    The settings for Internet APN are as follows:
    Profile name:

    User name:
    Type of sign-in info: None
    Check the box that says. “Use this APN for LTE and replace the one from my mobile operator.”
    Proxy server:
    Proxy port:
    Check the box that says, “Apply this profile.”

    The settings for MMS APN are as follows:
    Profile name:
    User name:
    Type of sign-in info: None
    IP type: IPv4v6

    Proxy port: 80
    MMSC (URL): http://mmsc.mobile.att.net
    MMSC port: 80
    Maximum MMS size (KB): 1024

    Make sure there is a check mark in Apply this profile, then click "save.”
