Everyone please listen. If you have a unlocked Nokia lumina 900 and T-mobile service you will have data and MMS problems when TMO go to LTE. DO NOT FRET. Here is the solution. 1st down load the Nokia network setup app. 2 load the following APN in both the internet APN and the MMS APN locations
fast.t-mobile.com 3 on the MMS apn there is a setting for MMSC Server you must add the following
http://mms.msg.eng.t-mobile.com/mms/wapenc DO not use
epc.tmobile.com as the MMS apn it will not work since the device is now on LTE.
Configured apn and mms apn with fast.t-mobile.com and the mmsc address and I'm still unable to send and receive picture msg on T-mobile LTE
.. please advice
In both the internet and MMS APN settings, did you guys only change the settings that were mentioned and leave all the other options blank?
EDIT: For anyone that comes across this thread via search results (as I did), I now have data and MMS both working with T-Mobile LTE on my Rogers 920. My settings are as follows:
Under the settings>cellular menu I have LTE selected as my highest connection speed and under the option for Network Selection I changed it from Automatic to T-Mobile.
Internet APN Settings
APN: fast.t-mobile.com
IP Type: IPv4
(all other fields were left blank)
MMS APN Settings
APN: fast.t-mobile.com
MMSC (url):
http://mms.msg.eng.t-mobile.com/mms/wapenc
MMSC port: 80
Maximum MMS size: 1048
IP type: IPv4
(all other fields left blank)
After changing these settings, restart to apply.
I'm sure it's possible I could get some better speeds by tweaking some of these settings, but I'm happy with the performance now and I don't want to unintentionally break anything because it took me a while to find a combination of settings that worked for both data and MMS on LTE. I'll update the post in a week or so to confirm if these settings are still working or not.
Update (4 August): Settings are still working for me. A friend of mine said his stopped working, but I'm still fine. So YMMV with these settings.
