    I am located in New York and have a Lumia 1020 - RM-875 | Nokia 909.1 version. I received the Cyan update last night and so far, it's fantastic except I cannot send or receive photo over text/ cannot send or receive MMS anymore. I spent a good amount of time at the Columbus Circle AT&T store and Microsoft store today... and after all the combos of troubleshooting no lack. Anybody having this problem? Any ideas...gurus or MSFT folks?

    I've got the same problem. MMS stopped working (can't send or receive) on my 1020 after the update. AT&T just completed its investigation and MMS still isn't working.

    You may need to add
    MMS APN settings. For some reason mine were wiped by the 8.1 update and my network profile won't update. You may have the same issue. My phone started working again after I followed the instructions from this thread elsewhere on this forum titled "Cannot receive MMS". I can't post a link, but the pertinent part (provided by Lindsay Brunetto) is copied below:

    I'm on at&t with a Lumia 1020 & I had to add back in my apn settings for MMS under Settings > Cellular + Sim > Sim > edit MMS APN. After I did that my mms's have been working ever since. This is what I used (only included fields which need text typed into them):
    APN: pta
    WAP gateway (URL): proxy.mobile.att.net
    WAP gateway port: 80
    MMSC (URL) h ttp://mmsc.mobile.att.net
    MMSC port: 80

    Note this is after I upgraded to 8.1.
