Internet: T-Mobile US LTE
Band: LTE:14
Data Speeds 20mbps down 3.6 mbps up
Mms: Works Flawless
Now My Problem. i cant make a phone call or receive a phone call
My Setting
Hidden Menu: *#22745927
enable hidden menu
*#197328640#
[1] UMTS > DEBUG SCREEN > PHONE CONTROL > NETWORK CONTROL > BAND SELECTION to set GSM Band preference
[2] CDMA > COMMON > NEXT PAGE > NEXT PAGE > PREF MODE SET to select GSM/WCDMA ONLY

WAIT 90 SECONDS THE REBOOT
VOILA! TMOBILE LTE.
Now i have succesfully unlock The Verison GS3 to Tmobile on Edge is there a way to port that radio. to get cell connectivity.
or if anyone want to try to tweak these settings to get more than just LTE connection. or get Voice over LTE working!
I do believe that you need the HSPA radio to make phone calls as T-Mobile does not yet support VoLTE.

What are you doing for apn setting? There are 3 for tmo-us that I know of. 1)gsm 2)lte 3)lte ipv6. You may have to down load an apn app. Apn manager pro worked well for me or offline sim apn database. Not sure what you use for network mode settings but use build prop editort open it up and find the settings telephony.lteoncdmadevice & telephony.lteongsmdevice use value 1 on both. Add lines if not there. This may open up more network types under setting/...network mode. Google build prop edit or tweaks to find more info. Good luck.
i535 radio/modem
Been thinking about you question to swap modems. Do not use the i535. The modem that would be ideal I believe is the r530m. That is metro PC variant. T-Mobile merged with the.... Do I need to explain more? Any how I can not say it will even work. I will say that T999L is no good. Found out first hand and still dead in the water with it. I would explore the APN settings and network selection modes with build prop mods before flashing. I am not even sure about the LTE bands and who has what and where. If I am able to revive my 530u I will see what I can find.
Where can I get the r530m modem? Can't find it anywhere.

So, is it possible to flash the R530M modem????

Seriously here. AT&T allows no option to turn LTE off or 3G for that matter. So which custom rom or modem allows for this? This is available on the Canadian version of the Note 2. T-Mobile's Note doesn't have a RAT locked modem either so they can force EDGE to save battery life. ATT RAT locks the modem on stock to disable network mode switching. It's really annoying for those of us in spotty LTE zones.
Anyone know?
Would like to know as well. Right now I'm forcing it to go to HSPA (all frequencies) though I would like to change it on the fly without having to remove battery > remove SIM > *#2263#...etc. Is RAT selection locked to the network or to the radio itself?

I believe to the radio itself. We need a Rogers modem but I'm not sure if that's a good idea.
A family member gifted me a Galaxy S4, however it is the SGH-M919. I currently live in Europe and 3G bands in my region are GSM 900/1800. At the moment I can't access 3G and any other type of data for that matter (LTE is not supported here). Is there a way to change T-mobile 950 and 1900 bands to my region ones?
Thanks for taking your time to answer
Sadly not.
Since the radio does not support those frequencies for hsdpa

So there's no way to fix it?
Hello Flex,
I have the same phone "Samsung S4 SGH-M919 - Tmobile" and I live in Hungary, it works fine with me all you have to do is just to switch form WCDMA/GSM to any other option "like GSM only" then back to WCDMA/GSM as a kind of refresh and the 3G will work fine after that, you can find this inside Settings > More Networks > Mobile Networks > Network mode, but unfortunately you have to do this every time you restart your device.
There is also another alternative solution is to reset the Access point names to default, you can find this inside Settings > More Networks > Mobile Networks > Access Point Names.
to be honest I don't know the reason of this error, but try what I described and tell me if it works with you.
Good Luck
Well. I have the exact same phone and have tried several ROMs, either custom or stock and basebands also. Nothing seems to work. The very few users who reported it was working didn't provide much evidence of it. Even Wikipedia says no 3G 900MHz availability for this phone. A simple edit to NV 1877 values won't solve it. I've tried that too.
Hi guys,
I just bought this phone a couple of weeks ago and i've been trying to get LTE working and I can't. Could you guys guide me to the correct APN for LTE and MMS.
Thanks in advanced.
That's all dependent on the carrier that you are with.
If you find that adding the APN doesn't get you LTE connectivity (but it does get you 3g or 3g+)... maybe try Settings, More, Mobile Networks, Network Mode and see if LTE is selectable there. Or dial *#*#4636#*#* , go to Phone Info, scroll down, and choose an LTE/GSM preferred network type?
I've seen several discussions about this but didn't seem to find a working solution. I'm currently using GNF1 V3 NB4, I tried using the apn settings for at&t and also called them to make sure they have the correct imei number. Also, for some reason under the "Network mode" I don't have an LTE option, I only have WCDMA/GSM, GSM ONLY AND WCDMA ONLY. I am able to get 4G but no LTE. Is there any solution or any other way to solve this problem?

Change ro.product.name= in the build.prop to say jfltetmo
will it also change the speed or just add an "LTE" symbol?
Give you the LTE option in network modes and change the icon. Speeds? Probably since youll have LTE back

ok, i have the LTE option in "network modes" now, however the speed is more or less the same and I don't have LTE bar, not sure whether it's because of my current location or what.. is there anything else I could edit to try to make it work?
If I change the ro.product.model , name and device to at&t values would I get the LTE speeds just like an at&t s4?

When I bought this phone from T-Mobile I was still on an AT&T plan. Before I jumped ship over to Net10 Wireless I used AT&T's LTE all over Pensacola. That was on a sim-unlocked, unrooted, otherwise 100% stock M919. Did you double-check your APN's? Perhaps you're just not in an area where you can pick up LTE?
Yes I use the correct apns the ones that at&t gave me, but im gonna try to go back to stock then change the apns to at&t and maybe that will work.. but even if it will, I don't know if I could keep using GNF1 or would I have to use a different rom, anybody else have or had issues with getting LTE on at&t while using custom roms and knows roms that work? (Preferably tw)
See your network type in settings > about phone > status. Try to get LTE with your AT&T SIM on another phone then install it back to your M919.

***SOLVED*** Thanks!
Hey guys I'm in need of the default settings for a Sprint S6's Testmode Menu. Specifically, the Network Controls, GCF, Preference Mode or pretty any way to set the S6 back to the way it came with Sprint plus the GSM unlock for T-Mobile. In settings/Mobile Networks/Network Mode was Auto before my mishap with the settings. I also had two APNS for TMO one for LTE data and the other for MMS and in service mode, it was set to Global. I changed stuff around in Testmode Menu and thought I had put it all back to how it was, but now when I set it to GSM/WCDMA/LTE, I will get GSM in areas I know for sure had full LTE. It will also say GSM/WCDMA/LTE in Network Mode through settings, which isn't an available option through there and which was originally Automatic when working. I wish to get back to the way things were. My phone was unlocked via GC Pro from an XDA member. I had changed the settings in hopes to improve my signal at homr because going to my neighbor's house improved signal. M changes worked, but randomly would say No Service. Anyway, please please help! If you have any other suggestions, that'll work to.
