Unlocked Rogers Nokia Lumia 920 & T-MOBILE USA MMS Issue

After hours of attempting to input the MMS APN settings for my unlocked AT&T Lumia 920, including an hour on the line with Tmobile technical assistance and even factory resetting my phone (which was a close encounter with bricking my phone), these simple steps had my MMS working in five minutes. Thanks so much for the info.
 
What was the sim card problem? Did you just get a new sim card? I too only have Tmo LTE my mms works 50% if WiFi is off. If my WiFi is on my mms want work. Please elaborate on what the sim card issues were.

Thanks
 
Try this fellas, got it from Tmobile today to finally get mine working....

Connection Name : T-mobile mms

Internet APN

Access point name : epc.tmobile.com
Username : Blank
Password : Blank
Proxy Address : 216.155.165.50
Proxy Port : 8080
Network Type : IPv4
Authentication Type : none


MMS APN

MMS access point name : epc.tmobile.com
Username : blank
Password : blank
Proxy Address : 216.155.165.50
Proxy port : 8080
MMSC address : http://mms.msg.eng.t-mobile.com/mms/wapenc
Network type : IPv4
Authentication type : none

important : after tapping it to make it active, restart your phone. :)

I have a Rogers 920 on T-Mobile. I don't have a proxy address in my internet or mms settings.
 
I had an mms sitting in my inbox and I couldn't download it. I then followed these steps posted on Nokia's forum and then I was able to download and view the mms.

1) Delete any existing Internet & MMS APN profiles stored in the handset, by tapping: Start, Settings, Mobile Settings, and scroll to the bottom of the screen and remove each apn manually by tapping edit, then tap the delete icon (looks like a waste bin) at the bottom right of the screen (you might need to tap "..." to reveal the option.)

2)Once all Apn's are removed, make sure the phone is connected via wifi., and email these links to yourself:

Link 1 "Access Point":

Link 2 "Network+":
http://www.windowsphone.com/s?appid=62f172d1-f552-4749-871c-2afd1c95c245

Link 3 "extras+info" :

------------------------------------------------------------------------------------------------------------------------------

3) Install each app from the link on your phone. On my phone, I already had 2&3 installed. Once all the above installed, the phone must be rebooted.

5) Now go to the settings menu, and scroll to the bottom. You should now see a new menu called: "Access Point". Tap it and you'll end up with a screen listing any APN's the phone has already found from the sim card (or previous sim cards inserted).

6) Select T-Mobile

Here is where I got the info Re: nokia lumia 920 access point is missing from s... - Nokia Support Discussions


So this fixed my issue with text messages on an unlocked AT&T 920 on T-Mobile. Today I see an update for Access Point. Anyone know if this update affects (i.e. breaks) anything?
 
This is not true.
DO NOT install the Access Point (same for Lumia 900 which has the same app called Network Setup) app which will cause you to lose Internet Sharing.
Roger's Lumia 920 already has the options to change Internet APN and MMS APN in the Cellular menu, use that, don't use Access Point app.
The Access Point app will modify the internal Internet Sharing APN which you can't change manually that cause Internet Sharing not working (it will show up saying contact your carrier...)

I have the Rogers Lumia 920 and have both MMS and Internet Sharing working on T-Mobile (without the tethering plan).

I have an AT&T Lumia 920 that i'm using on T-Mobile. Internet sharing is working, but MMS is not. What should I do? Can you provide a step by step? I don't want to install the access point because I don't want to lose internet sharing, thanks!

megazone, can you share the APN settings you manually inputed?
 
The new 8.1 update seems to break either hack on Rogers Lumia 920 on T-Mobile USA. Now I've lost BOTH Internet Sharing and MMS.

I'm thinking of hard-reset and then getting rid of the blasted Access Point application.

====================

After a bit of research....

We can get rid of the Access Point panel by setting the date of the phone 100 years into the future and then trying to open Access Point. At that point it will say the App has expired and to uninstall it. Hooray!

That said, removing the Access Point app and manually entering the APN information didn't return my Internet Sharing.

LTE works and MMS works, but I just get an "upsell" message when I already have tethering and data on my T-Mobile Plan.

I want to switch to the NZ/Australian firmware but I think it can't be done with Win7 64 bit, and certainly not on MacOS with Parallels. I think I need to find a computer with Windows 8 to run the Nokia Care Suite effectively unless someone can point out or instruct me otherwise.
