So... I've put one of my Lumia 900s on Straight Talk, however when I followed their settings guide data and mms worked, but all of my live ID and Bing features did not. I tinkered myself and researched and then deleted the proxy address and proxy port # I'd had in under internet apn in the network settings app. That seemed to get all my Bing and Live ID features to work, however now mms is non-functional. I did not disturb the mms settings, so I'm unsure as to why my picture messaging is no longer working. Any help would be appreciated. I'm having a hard time searching on here, but love the community's feedback

delete everything under the cellular APN.

Okay. The only thing under the cellular apn is att.mvno. Delete that is what you're saying?

Wow thank you so much. Everything is working perfectly now. I was beginning to think I'd have to go back Android or iPhone... I can make an exception with losing my phone as a WiFi hotspot ( and that's huge for me) but losing the marketplace, all windows features, and mms is just not right. Lol. I use my phone for a variety of things, and now that I know I can successfully switch from AT&T without losing mug of anything, I'll be glad to take the savings.=)

I've put in the correct information that straight talk gave me, deleted everything under the cellular apn also.
Picture messaging still doesn't work for me ):
Any suggestions?

I am having similar issues. I put all the APN data(Internet & MMS) using the "Network Setting" app into my phone. I deleted all the info from the cellular settings. I still cannot use the MMS. Any suggestions?

Thanks

Make sure your connected to wifi and have downloaded Network Setup in Marketplace
Go to Network Setup and it will say like At&t-LTE1 (or whatever is showing is fine) hit the little plus button at bottom you are now going to manually enter everything
Connection Name: Put whatever you want I put ST Next is Internet APN at the access point name type: att.mvno then leave everything else in this part blank scroll down to the next one which is MMS APN: mms access point name type: att.mvno next proxy address type: 66.209.11.33 proxy port: 80 leave username blank and password blank then under that is MMSC address(dont miss it it is on very bottom here and type this in : http://mmsc.cingular.com and the hit the save button on bottom...MAKE SURE YOU SAVE.......then go to your phone settings then to cellular go to add apn on bottom and trash (or delete same thing) what is there......Viola you have straight talk with mms, text, data and voice...Awesome.... if for some reason you dont just restart phone and if you did all this you will have it.

Thank you ,thank you, thank you! Had to reboot Nokia Lumia 900 but the phone will go straight to settings. Pick new APN and your done. Countless hours trying to figure this out. :-)

I tried all of the apn setting deleting stuff and adding stuff. I think I've tried every single way and my data and picture messaging still will not work at all. I got the sim car after they switched to only Tmobile and I had to cut the sim card in order to fit my phone so I'm not sure if that had anything to do with it.
