    Are you using an AT&T or T-Mobile Straight Talk SIM?

    Was fighting with the same issue with my unlocked 520 Win8.1 on Straight Talk (AT&T Sim.)
    Here are my settings that work...

    Internet APN:
    APN = tfdata
    (all others blank)

    MMS APN:
    APN = tfdata
    UserName = (blank)
    Password = (blank)
    Authentication type = PAP
    WAP gateway = mms3(dot)tracfone(dot)com
    WAP gateway port = 80
    MMSC (URL) = H tea tea pea (colen)(backslash,backslash)mms-tf(dot)net(backslash)
    MMSC port = 80
    Maximum MMS size = (blank)
    IP type = IPv4v6

    Sorry about the workaround - wp thought i was posting a link and I wouldn't let me reply...
    Hope it works for you!

    That would deffinitely work if windows 8.1 had the option to edit the MMS APN but ATM it looks MMS settings will probably be stuck to whatever settings it was on on the previous provider

    My wife's unlocked HTC 8S is now on Straight Talk, AT&T sim, and the prior carrier (Cincinnati Bell) had opted not to list the "add MMS APN" option on the settings menu. So MMS is not working, though data is fine. Is there no hack to get at those settings?

    I've tried HTC's Connection Setup app, but none of the logical choices (AT&T, Straight Talk, Tracfone) seem to work to get MMS messaging working.

    Settings > cellular + SIM > SIM settings > edit MMS APN

    That WAP gateway (URL) is the tricky part and thanks to MChaney3563 for this post in the 520 forum that got me configured for ST on the ATT style SIM.

    Let us see where we are at... Does Internet work? Just MMS (picture text) out?

    Have you tried both of these settings configurations?
