Hey guys. Is the Verizon S5 CDMA + GSM?
Is it factory unlocked?
Can it be used on T-mobile with everything working correctly (LTE/4G)?
Thanks

I don't know the answer to your question but I can confirm that the Galaxy S5 that I received from TMobile was in fact LOCKED.
I called the support # and was told that I had to have service and use it for 40 days before it could be unlocked.
I PAID THE FULL PRICE ($720 with tax)!!!
I asked to speak with a supervisor -- after 10 minutes on hold -- no change.
I told the store that I was going to bring it back because I didn't pay $700 for a locked phone. Everyone has been nice but it's locked for policy issues and not for technical reasons. I flew to Canada when I bought my iPhone4.
And, AT&T is worse -- one guy told me 3 months and tech support said it had to be active for 6 months.
>> So, my AT&T sim card is not working in my SM-G900T model.
It is GSM/LTE unlocked (as are all Verizon LTE devices), but I'm pretty sure it doesn't have T-Mobile's LTE bands (or at the very least it doesn't have all of their bands).
From what I have been reading, on a Verizon phone, calls and data using GSM and WCDMA bands would work. But LTE bands are Verizon specific hence would not work.
Tl; Dr Voice /data using GSM/WCDMA. No LTE.

Does this mean, once unlocked, T-Mobile and AT&T versions would work on each other's networks including LTE?
I also noticed that with S5, there aren't GSM carrier specific versions. Meaning they are going IPhone route with making all GSM phones enabled that for that country's LTE bands. Is that right reading?

it is unlocked
I am using the verizon s5 on tmobile. It is unlocked and can be used on tmobile LTE. However there are only set modes. LTE/CDMA GSM/UMTS AND GLOBAL. Which means you can't use lte and gsm at the same time (no lte data and voice calls). I usually keep it on gsm, and when I need speedy data I switch it to lte.

How? If you put a TMobile SIM in the phone, or any other foreign SIM, it boots but receives no service. This is in line with almost all other Verizon branded phones (excluding Apple) -- where the phone works (unlocked) outside the US, but won't roam to ATT/TMo in the US.
Pictures please. For the record, my S5 doesn't register on a network with a TMobile or Australian SIM. The Australian SIM in a Nexus 5 roams to TMobile.

This was probably true about a year ago but the recent releases from Verizon, e.g. iPhone 5/5s and galaxy s4 has been fully unlocked world phones. I'm sure there are a few other phones... I think lg g2? I'm not exactly sure. But I have personally stuck my sim(T-Mobile) into my friend's Verizon phones (s4 and iPhone 5s) and they work right away after a reboot. Only problem might be an edit in APN for data and mms. Just sharing my experience, you should check out your phones again.

Not trying to be a jerk, but unless you tried this process in the actual phone in question, then you don't really know if it works. The phone DOES NOT just magically work on TMobile if you put a SIM in, you receive NO service. Now, I didn't go mess around with APNs -- typically those are only for MMS/Data. This is also true for several other phones:
Razr HD / Maxx HD
Galaxy S3
In the past, when the phones were SIM locked, a foreign SIM would prompt for an unlock code before the phone even booted into "normal" Android. That's not the case here -- because the phone is not SIM locked -- but I do believe it is network locked to VZW only when in the US.
For the record, I did try this in my S5. I will be going to Australia next week and will try a Telstra (or perhaps Optus) SIM over there to see what happens.

Yes, I haven't tried it on the s5, but I was pointing out fact that it does work on recent releases which someone confirmed worked on s5 by just plugging it in. I'm also correcting your statement " This is in line with almost all other Verizon branded phones (excluding Apple) -- where the phone works (unlocked) outside the US, but won't roam to ATT/TMo in the US." because Verizon apple does work in the US on T-Mobile and AT&T beginning from iPhone 5. I believe the 4s was still carrier locked.
I was a wireless agent not to long ago, so I know how these things work, not that it magically just works... I'm just sharing you how some recent releases from Verizon has been world unlocked and a few others have mentioned that they just plugged it in and it worked. So good luck and have fun in Australia.

OK Thanks.
It is odd that the apple phones -- and some of the Android phones -- are totally unlocked so that you can use them on ATT/TMobile in the US -- but some (like the S5, apparently) are not. I still am interested to know how some of the other users in this thread got their S5s working on TMobile...
Why would anyone want to buy a Verizon GS5 and use it on T-Mobile? The bootloader is locked and there is currently no unlock method available.
Would you like to exchange?
Would you like to exchange your verizon s5 with my tmobile s5?
i wanted to use it for verizon but the phone is locked to tmobile and at&t.
It would be ideol if i can find someone to exchange it with someone who has a verizon s5 and is looking for tmobile or at&t s5.
thanks,

I can confirm the Verizon GS5 is compatible with T-Mobiles LTE network I'm using one now with LTE all you have to do is go to settings mobile network and switch to Global mode some times you'll have to toggle LTE then back to global to get LTE to kick in.
I am able to successfully use my VZ Galaxy Note 3 and my wife uses her VZ Galaxy S5, both devices on T-mobile Edge, HSPA, HSPA+ (21mbps), and LTE (band 4) frequencies. These devices unfortunately will not do DC-HSPA+ (42mbps), but that's not a big deal for us because LTE coverage is good where we live. We have no issues with making voice calls, or sending SMS/MMS, and don't have to switch APN's or toggle between Global Mode or GSM/UMTS mode. We leave them on Global Mode with the correct APN settings.
Here's the guide I followed for both (with correct APN settings screenshots to accommodate for MMS on page 4 or 5 i believe):

How did you unlock the Verizon S5? BTW theres a bounty on doing so.
..
This is all new info to me. I have an AT&T galaxy S5 that I want to use on Verizon. Is it possible or do I need to trade for a Verizon-specific model?
I've been combing the forums and I'm still unclear on a few things and looking for help. Current AT&T customer and I plan to switch to T-Mobile soon. Any confirmation or corrections/answers to the questions/statements below would be really appreciated.
1. The 935F variant is the international model that works with all GSM carriers (and I assume without any carrier bloatware) but VoLTE and wifi calling will not work on any GSM carrier here in the US. Theres a secondary 935F model (d?)- whats the advantage there? Shopping tools that let you compare the models show no difference but always priced differently. There is something I'm missing.
2. The 935U variant is official US unlocked model for use with any carrier. Only silver. I have not seen any posts confirming that VoLTE and wifi calling works- and will continue to work if you switch carriers.
3. Lots of listings for factory unlocked 935A variants. Official AT&T version. That just means a reseller has applied unlock codes to each and resells them? I'm very unclear here. Listings always say compatible with all GSM carriers. But will AT&T bloatware, logo continue to survive? And again, will VoLTE and wifi calling work and continue to work if I switch carriers. This is also the cheapest phone to buy virtually new. But if truly GSM compatible with features that are important to me are intact among carriers- what would I get for the significant premium to get the 935U? Besides, I wanted black.
4. Black Pearl- has this been released in the US and in any specific model? I have not seen one.
Thanks in advance. Really appreciate it.
FD is dual sim. You can put 2 GSM simcards there and both are active. Can send and receive sms or calls.

You can install 935U stock firmware on att/tmobile/verizon version. If used on tmobile network, you will get wifi call and volte. For att you have to install or have att stock.

1. 935F is the European / International model. 935FD, D stands for Dual-SIM, both slots will be able to accept a GSM SIM card and are usually used, as one for work, and one as a personal number. Dual-SIM however, is not a popular concept in the US.
2. Check the 935U threads, if a CSC flash is possible, it might work. Though, I'm not sure.
3. Yes, if you have an AT&T phone, it'll still have the AT&T ROM, which will always remain the same, regardless. It will work with other carriers, meaning SMS, Data and calls are compatible, but things like VoLTE and WiFi calling might not work on the carrier that the phone isn't intended for.
4. No it hasn't. It's been released in South Korea with 128GB of internal storage. Also available in the UAE, India and some other Middle Eastern countries. Only in a Dual SIM Configuration (SM-G935FD), and with 128GB of internal storage. It's a limited edition phone, and not sure if it'll be launched in the US.

A couple of followups if thats ok:
1. So if I purchase a "factory unlocked" 935A, before I insert any SIM, I can immediately flash the 935U firmware and it will remain unlocked? I couldn't find a single post that said VoLTE or Wifi calling worked with the 935U firmware on T-mobile (AT&T- what do you have to install?)
2. Flashing to firmware is not considered rooting the device? My work will not let my device connect to the network if it is rooted.
Seems like there is no reason to spend the extra money for the 935U variant. I can save hundreds and purchase an unlocked 935A and flash the firmware. I've rooted devices before and the process looks similar.
Thanks.

According to other people in verizon 935u thread and att 935u thread, volte and wifi call works on tmobile. For att wifi call and volte, it must be a ATT carrier firmware. ATT only let their branded phones have wifi call and volte while tmobile allows any phone to do this. That's why with 935U wifi call and volte will work fine on tmobile.
Every time you insert a new sim the phone will adjust settings, so there's no relation with what you can install.
Flashing is done through Odin while phone is in Download mode. There no root involved.
I've searched and cant find anything but the bands for either service. Which they use a lot of the same. Is a T-Mobile branded S8 usable on Verizon? Full 4G or not? Thanks!
its a gsm device. i believe the internet data part will work but not phone calls

Did you ever figure out if this was possible? I can't seem to find a definitive answer.
Bump - anyone know if this will work?
As soon as I get mine unlocked I'll let you know as I have Verizon. All s8 models are the same but I'm sure the T-Mobile software has blocked Verizon bands. I'm sure if you flash Verizon software it will work just fine.
I have an unlocked T-Mobile Galaxy S8+ and it does not work on Verizon. I went into a Verizon store and they tried for an hour to activate the phone to no avail. They tried multiple different SIM cards and none of them worked. If anyone has better luck, please let me know. But they weren't able to figure it out at Verizon.

You need an unlocked Tmobile S8 or S8 plus.
Read the instruction in "Flash any carrier 100%" to flash to the carrier you desired, activate all bands.
Then use it on Verizon.
You need to flash your phone to Verizon to work. I did the exact opposite actually. I bought a Verizon device and flashed it fully to T-Mobile. Works perfect on T-Mobile because every US Galaxy S8 for the major carriers is SM-G950U. They support each other's bands, their just disabled by the carrier firmware.

I did not have any luck flashing it to the official Verizon Firmware, but I was able to flash it to the G955U1 firmware. The official unlocked US Firmware. Make sure your t mobile device is SIM unlocked by TMOBILE before you do this.
1. SIM unlock device by tmobile (pay off device, meet the 40 day requirement, etc).
2. Flash to G955U1 (S8+) or G950U1 (S8).
3. Insert Verizon SIM or ATT or any SIM.
4. Your phone will give you pop up warning saying it needs to restart to configure the new SIM.
5. Enjoy your new carrier.
Did you use a Verizon SIM and did you get both VoLTE and WiFi calling to work with the G955U1 FW?
my 2 cents

I went to Verizon store and used one of their Verizon SIMS from a display model of the S8+. Voice over LTE works, Data works and I was not able to test Wifi Calling at the store. I even ran a speed test and had about 27mpbs down and the associate ran speed test on his phone and he got about 20mpbs down connected to the same server using the Speedtest app. I ran the LTE discovery app and shows me connected to LTE Band 13.
Hope all of this helps.
Bringing S8 to sprint?
Did you anybody try to use a TMobile or other branded S8 on Sprint? The Sprint customer support is not able to add the IMEI to their database for whatever reason.
@Aephel
@T33H00
Silly question, but does doing all this void Warranty? or is there no such issue anymore?
For example flashing Verizon Firmware onto a Tmobile Unlocked.
I unlocked my t-mobile s8 plus and attempted to use a Verizon SIM. It does NOT work. Verizon states that the IMEI is not in there database and that they cannot activate it.
Hey guys,
Context:
Ported my phone from Verizon to MintSIM, which uses T-mobile towers
Successfully flashed G950U1 to my Verizon S8, which supposedly allows me have an "unbranded" S8
While MintSIM data is now up and running on my Verizon S8, I want to make sure I am getting the best LTE coverage. I believe it is Band 12 that T-Mobile often uses for building penetrating LTE coverage, but how can I check if that is being used? I have tried numerous dialpad entries and even got to a service menu, but it said "Service Menu does not exist". Any help on this would be greatly appreciated!

It's blocked on VZW models. Only option is to download signal check pro. That will show you what band your on.

LTE Discovery app from Play Store can also show you the band you are on.
You used to be able to flash G950W firmware and go into settings on that then flash U1 over it with home CSC to keep settings but as of the last W update or so that doesn't work anymore either.
I purchased a Verizon (unlocked) S8 on ebay. What's the best firmware to flash with to use on T-Mobile? Thanks!

Bumping this ish. I have a SM-G950U that was bought from Verizon. I am using it with T-Mobile. I need to know what I need to do in order to get band 12 to work. I'd prefer to flash an unlocked rom onto the phone so I don't get the annoying Verizon sim notification. But if I should flash a different rom, I need to know. Thanks.
If I buy used T-Mobile can I Flash AT&T firmware on it so I will have AT&T Enhanced Messaging and Wifi Calling Just as if it was an ATT phone????? Thanks
If the phone is network unlocked in theory the sim it sees when you first boot from setup it should then download all the carrier software and features. There is only one carrier U firmware so there isn't specific AT&T, T-Mobile. Now if AT&T tracks their IMEI's that were meant to be on their network then that may be where this all falls apart and some features may not come over then.
At least that is how it has worked in the past. Someone else feel free to correct me if I am wrong.

I saw a report on the forums here where someone flashed the att userdata and wiped and all of the carrier features worked.
I know on the 9/9+, even with the BOYD firmware, or flashing att bloat would not make a NON-ATT purchased device have advanced messaging /wifi calling / VoLTE. The trick was to activate that stuff on an att branded phone and then swap the sim.
It was very much a YMMV.
Similar issue here. My problem is i bought a s10 plus AT&T and it was supposed to be unlocked, however it wasn't the case. Mine is still AT&T locked and when i called them about my issue they said i would have to get service with them for a few months then i could end the service by paying the cancellation fee. I could then unlock the device. They also told me that my phone has an unpaid balance that would have to be paid prior to starting service. I have tried to contact the seller but to no avail. Anyways, my question is can I flash T-Mobile stock firmware to this phone and use it on T-Mobile?
