This is not 100%, but just my understanding. The T-mobile version shouldn't have the radio frequencies , or even the same technology (gsm vs. CDMA) as the verizon S4. Dont think there is any amount of software modifications that an allow it either.
No, you cannot use it. It lacks the hardware radio.

Damn. Didn't think so but was hoping so!

It's possible. %100. I'm going to start working on it now that I got my VZ S4 from work...(I have tmo for my personal phone). Please....PLEASE....PLEASE!!! let's not have anyone else say "it's not possible". I'm begging you. Before you spout off about this that or the other thing...read up on the phone. Learn about frequencies, modulation, SDRs...etc.

Its possible but not probable because VZW is still using CDMA so is Sprint and I do not think the TMo/ATT/GE version have the baseband nor the radios to support CDMA. Once LTE band 4 is enabled and VoLTE is prevalent then the phone can be seemless across carriers.
I know it work the other way around
I put a prepaid att sim card in my ZVW s4 and it worked! As the vzw s4 comes stock as a world phone and can be used on gsm networks. Without unlocking. So if you unlock your TM s4 you should be able to pop in a vzw 4g sim and be OK?
I don't think you will have 4G though if you got a buddy with a vzw 4g phone grab his sim and try it after you unlock.
Att - gsm
T-Mobile - gsm
Sprint - cdma
Verizon - cdma / gsm 4g lte

Again the Tmo/ATT/GE do not support the LTE bands on VZW/SPRINT nor do they support CDMA/EVDO.
The VZW variant should work on any GSM network with a sim swap and APN switch but LTE will be limited or not available.
Right so he won't get 4g/4g lte
But should be OK on 3g after the apn settings are configured I believe. Hope this helps
I tryed to post an image or link but I can't yet cuz I'm still a noob here at xda sorry

You CAN, but that does mean you'll want to.
T-Mobile utilizes 2 spectrums for HSPA+ and LTE. 1700/2100 for both. Without access to both spectrums the device will not receive data. Best you'll get is EDGE, which is only from interoperability with AT&T.
There are not interoperability standards for 4G LTE so you couldn't use this on AT&T LTE either.
So yes you can do it, but you won't like the service.

You cannot use the T-Mobile S4 on Verizon, period. It doesn't support CDMA or LTE band 13 which are the only bands that Verizon currently offers service.
Now if you had a Verizon S4 you could use that on T-Mobile since it supports HSPA on the PCS band and LTE on band 4 which are both used by T-Mobile for 3G and 4G but that isn't what the original poster asked about.

The question is will a t-mobile S4 work on VZW. The answer is no, it will not. Not unless that MDM9215 spontaneously changes into an MDM9615.

Can you guys please read the data sheets on the APQ8064T, MDM9215M, and WTR1605L...then come back and tell us how it won't work.
Edit: Hint....the 9215 is what is inside the Nexus 4....which I also own....running LTE on T-Mobile...
Yes, but can you use that Nexus 4 on any cdma carrier?

With the right hacks...yes. It's possible man.
This article (from QComm) states that the 9615 is capable of CDMA
This link shows very little difference between the 9615 and the 9215...
Again, I implore you all to be diligent when it comes to exploring new ideas...don't just dismiss something as not possible. There's no such thing.
Edit: Just incase the second link to the PDF doesn't work or is REALLY slow...I've attached the document to the post. Also, I took the time to spoon feed someone the info in another post linked here ....
Edit 2: Nevermind, the PDF is 2.5MB...won't let me attach it.
You may want to do a bit more research on the MDM9215. It does NOT support CDMA. It is only used in UMTS/GSM + LTE devices. CDMA support is what differentiates the MDM9615 from its sibling. This was explicitly noted by Qualcomm at UPLINQ 2012 as part of their QCMB API presentation.
So once again I will reiterate that a T-Mobile S4 lacks the necessary hardware to operate on Big Red. Furthermore, it is a simple matter to note that the MDM9215's commercial availability is limited to UMTS/GSM + LTE devices.
No amount of mad hacking skillz can overcome that hardware limitation. It would be necessary to replace the MDM9215 with a MDM9615, which is far from being a simple plug and play operation.

Crap..my retarded ass read it as VZ S4 on Tmo...not the other way around...in that case, you're right...my apologies...I've been researching getting the VZ S4 working on Tmo....since that's what I'm going to be doing.
Again...my apologies.
I have the Verizon galaxy S4 running Loki'd Hyperdrive rom and I'm on T-mobile, but I only get 2G (AKA edge and too slow for mms) how can I get T-Mobiles HSPA+?
I was using AT&T's AIRVOICE and got HSPA+ but always got redirected tot he GoPhone account empty screen. so HSPA+ worked but AT&T wasn't fond of my s4 being verizon branded. So I switched to T-Mobile and I HATE Edge. but it's better than nothing.
You can't get a device on Verizon that was not part of the Verizon database to work.
Look at the new Nexus 7, even with the correct frequencies, people are having a hell of a time trying to get a device with the right LTE bands to activate.
If it's not sold as a Verizon device, sell it and buy something else.
i have a tmo d801 asnd my plan is att ..The phone only work edge not 4g ...with the corect apn only work edge..
ok the phone now is in 4.2.2 with custom rom all variant and root ....
The cuestion is ? i need att radio to my phone or maybe have other alternative to work in 4g ...
No, the network so phone are 2 different entities. A total mobile phone will use T-Mobile baseband but I know T-Mobile phones have the 1900mhz band which should give you hspa on att at least

You should be able to get LTE with no problems.. You need to have the correct APN... Or the AT&T service near your house is useless..

So I am currently using my VZW G3 on T-Mo. Anyone know of a way to get WiFi calling and messaging enabled on this. Maybe flash the calls apk from a t-mo ROM? Anyone have any ideas or success doing this? Oh and I'm only using t-mo on a VZW G3 till I can buy the t-mo variant.

I have never heard of anyone being able to get that to work, without a T-Mobile phone and post-pay sim. I just use Google Voice, now, whether I am running with my Verizon sim or my T-Mobile prepay sim. The Cricket sim is unlimited voice, but most people call me on Google Voice now anyway. Rings all my phones and my tablets too.

Has anyone been able to figure this out?
I have the Verizon Galaxy S 5 and and I would like to switch it to a T-Mobile ROM. The hardware is the same so it doesn't matter what T-Mobile ROM I choose does it?
I apologize for the noob question but I didn't see an answer on this fine forum. Thanks!
Hardware is not the same. Two different technologies cdma vs gsm. Verizon phone should be able to accept tmobile sim when unlocked. They usually work with foreign sims without problem but they are locked for domestic (US) carriers. Maybe someone have some info how to unlock it for US providers.

Verizon S5 is already unlocked for US carriers by default and it will connect to T-Mobile on LTE Band 4 network and their 1900Mhz 3G/4G network. No AWS support.
The issue is the locked boot loader. Flashing a custom ROM is not possible. So no VoLTE or WiFi calling.

Ok so jut as the title says, i have a VS985 currently running Skydragon, but ive tried several different roms, all lead to the same issues, i also tried flashing every baseband from 10b to 23c, all with no change, basically, i get LTE in alot of place, but i have no signal in just as much places....i tried enabling all LTE bands as well through the verizon hidden menu, so my question is: have any of you run into the same issues running either Tmobile/Metro/Simple Mobile/Solavei/Straight talk or any other service that uses Tmobile?
Any help would be amazingly appreciated!
Thank you fellas
T-Mobile does not use band4 for LTE in a lot of areas, and the only T-Mobile band the vs985 can use is band4. So, you get H+ or even edge in those areas.
