Is Verizon S5 unlocked? Can it be used on T-Mobile?

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?

Possible to use a Sprint HTC 10 on Verizon with unlimited data & hotspot?

Hi all,
I didn't see anything from reading through the forum on using a Sprint HTC 10 on Verizon. It sounds like there's been success with Tmobile and AT&T.
So far, this is what I've found:
-Sprint HTC 10 should have all the LTE bands necessary for Verizon
-Sprint HTC 10 needs to be sim unlocked before anything can be done
-S-Off + root are required for any potential workaround for Verizon, as the appropriate radio needs to be flashed
How far off base am I? I am intrigued because I am on Verizon and I'd like to take advantage of the sprint HTC 10 sale that's supposedly going on right now. Thanks in advance!

I have the same question. I'm trying to jump on that but for T-Mobile. I'm just worried I won't be able to get the device unlocked.

Historically, Verizon and Sprint don't activate each others' phones. They're the two big CDMA carriers that don't use SIM cards, but activate by ESN directly. But there are always those who get lucky.

? anythin

I've been working on that recently. I actually want to be able to switch between Sprint and Verizon.
Sprint has to activate both the phone and the SIM. Verizon has moved to just using SIM cards. I've been able to move a Verizon SIM between devices and have everything work, even on devices that aren't official Verizon devices and even some that only support part of the bands Verizon uses and work on the ones they support.
With the HTC 10, I've been able to get S-OFF and unlock the phone myself since Sprint wouldn't do it. When I put in my Verizon SIM, it recognizes it but for whatever reason is unable to connect to anything but 1X Roaming (probably on Sprint but it won't say). Poking around in CDMAtool hasn't helped much.
I'll update this if I ever figure it out.

Any updates? I'm curious myself. I have the Sprint HTC 10 and am working on finding an MVNO that I like, some of the Verizon ones are tempting.

By perfectly do you mean volte and Wi-Fi calling are working for you? If so please point to the guide you used. I can't find where anyone using a sprint 10 has gotten those things on T-Mobile.
I would be surprised if a sprint 10 used on Verizon would have that work too but haven't seen any mention of it.

I unlocked the bootloader and installed ViperRom, picking the US Unlocked version as my device. I have working VoLTE, but not wifi calling. (Note, this is on Mint Sim, which uses the T-Mobile network)

yeah it would be great if someone could give a for sure answer to this. I've found a lot of post giving conflicting information all over xda and r/htc10 about this. I would love to buy a used sprint htc 10 (seems to be the cheapest version by far) and use it on a verizon mvno, but until I know for sure it works I' not going to do it.

If I switch my SM-950U1 unbranded to AT&T ROM, will I get wifi calling and HD voice?

If I switch my SM-950U1 unbranded to AT&T ROM, will I get wifi calling and HD voice?
I have an unbranded SM-950U1 on AT&T. The phone works fine for calling (non-HD), LTE, and everything else. The only two things that don't work are wifi calling and HD voice. If I switch to an AT&T ROM, will I get wifi calling and HD voice?
I've read lots of posts saying it should work, or that it shouldn't work, or that it might work, or that somebody had a friend it worked for, or that somebody heard of somebody where it worked for three days, and then stopped. I've heard that I need to give AT&T an AT&T branded IMEI number to associate my sim with, but that will only make it work for a week.
What is the truth? This phone has been out for over a year, somebody must have put an unbranded U1 on an AT&T ROM by now.
I know I can try it and see, but if there is a definitive answer then I know to either go through the trouble, or not bother. I'm hesitant to wipe, because I've never wiped this phone, been through the beta and oreo and everything, and it's working great, with good battery life. My only problem is that I'm occasionally in buildings with wifi coverage, but poor mobile reception, and would like wifi calling in those situations. If I can get wifi calling then it's worth the trouble of wiping, and dealing with AT&T bloat.

It all depends on if you are using AT&T's prepaid or postpaid service. If you're using AT&T prepaid, then you probably won't be able to get wi-fi calling on your phone. If you're on AT&T's postpaid service then you should be able to get wi-fi calling on your phone. I know this from my own personal experience. I had their prepaid service and couldn't get wi-fi calling to work on my phone. When I switched to their postpaid service then I was able to get the wi-fi calling to work for me.

Did you ever get Wi-Fi calling etc. to work? I also have an unlocked S8 (SM-950U1) direct from Samsung and would like to have these features work. I've online chatted with multiple techs, received a new SIM card and still can't get it.
I've read things about changing my CSC and flashing an AT&T ROM but would also like a definitive answer.

No, I never got it to work, but I didn't try installing the AT&T rom. I did try giving AT&T the IMEI number from an AT&T branded S7, but that didn't work. After they made the switch, my phone had lots of trouble with the network for about 15 minutes, and then it started working again. My web profile at AT&T also switched from S7 back to unknown, so I'm guessing their systems picked up I was using a different IMEI.

activate ATT v35 on sprint or any cdma mvno

tried to run the imei number on the sprint and verizon site, says cannot be activated. Went to sprint and called verizon, says att branded phone cannot be activated. This is unlocked, works on tmo. tried searching for a solution in the forum but no dice.

Doesn't matter if it's "unlocked", other carriers have their rules for what they allow on their networks. Most AT&T phones don't have CDMA, and Sprint, Verizon (for now) still uses CDMA.
On non-branded phones you won't get VoLTE from most carriers (T-Mobile is the exception) and without VoLTE you would need to temporarily drop down to CDMA for voice calls on Sprint and Verizon.
Even on phones that have CDMA, like the LG V30 US998, Verizon still wants you to buy their branded phones -- because end of this year when CDMA goes away, those phone still won't have VoLTE. So in a few months those phones won't be able to make phone calls. I have two relatives with LG V30/V30+ US998 on Verizon. Don't ask how, there are ways. But even of 2020 they will need new phones when Verizon kills CDMA and they can't get VoLTE on non-Verizon phones.

As an owner of an AT&T v35 I can tell you it will work nicely on the Verizon network including VoLTE and VoWIFI. You do have to jump through a few hurdles. You will need a SIM activated on the Verizon network. That may mean buying a new phone from Verizon. You also need to SIM unlock the v35 by buying a code from a site like codes2unlock.com. You may also need to cross flash to the NA rom. These things should be done in that order, and there is no going back to an AT&T rom afterwards.

Chazz, can you clarify this? I have a US998 v30s running on Verizon with VoLTE. It was my understanding that it will not be affected by shutdown of cdma by Verizon. I like the phone and want to continue using it.

My brother-in-law found Verizon store rep willing to break the rules for he and my sister's USS98 V30+ (converted from Sprint LS998). They switched from AT&T to Verizon.
This guy said "Verizon wants you to buy their phones, of course. They'll tell you this phone (US998) won't work, but it will." He activated two SIM cards and put them in their US998.
He said "If you have any issues, ONLY see me here at this store. Don't talk to any other reps about this." Wink, wink, nudge, nudge. (Monty Python reference.)
My brother-in-law and sister don't have V35 on Verizon, but you probably have VoLTE because you enabled VoLTE on another phone (Droid Turbo)? I don't know if they have Verizon VoLTE on US998 V30+, but I assumed they didn't...

If you have Verizon VoLTE now, then nothing will change.
I assumed my brother-in-law and sister don't have VoLTE and are temporarily dropping to CDMA for phone calls. But I have no way of easily checking. Neither would know what "VoLTE" is nor "CDMA".
I merely told them their US998 phones were carrier unlocked and would work on Verizon -- if they got already-activated SIM cards. My brother-in-law used his considerable sales skills and found a helpful rep.

thanks a ton @chazz for the clarification. i have already move to AMZ 9.0 which looked to be pure android. was not able to get NAO due to error(sha256 auth error). AMZ was the only one that worked from multiple different firmwares(lgfirmware /sammobile) from us region and it works awesome.
For the verizon sim card, can i buy flip phone or a throw away verizon smart phone with the activated sim card and use it with the v35. similarly can you use the approach for sprint?
Again your response is much appreciated.

You should consider features you want to have on your account when buying the phone from Verizon. Some can be toggled through the the settings menu on the v35 like Advanced Calling for VoLTE, but others can't like visual voice mail. Ask to have them activated when you buy the phone. Keep that Verizon phone, you may have to get help in the future from Verizon and it will come in handy! They won't be impressed with the v35.
I don't have proof of it and am not in a position to test, but I suspect you cannot activate a Sprint sim on a Sprint phone and then move to the v35. My understanding from reading about the open market ULM and AT&T branded v35 is that Sprint maintains an IMEI whitelist. Sprint only allows Sprint branded phones on their network. This is why the ULM model is preferred for Google FI.
Please post what you learn so others can benefit.

4g calling on US996?

I'm currently using a US996 (the "real" factory unlocked version, not the US cellular one), and was hoping to do so for as long as possible. Unfortunately, my current carrier is AT&T and it seems that they will be dropping support for 3g calling early next year- which I am told will render my model unable to place or receive phone calls.
Anyways, I have *heard* that my device will be supported if I switch to T-mobile, but this comes from some googling a year or so ago and probably some less-than-reliable sources.
I was hoping to get a run-down on what my options are if I want to retain both my current device and ability to make phone calls come 2022. I currently have an unlocked bootloader + LineageOS installed on my phone as well, and would prefer to maintain that rather than having to use a locked-down carrier ROM

I have seen mixed reports from users who got VoLTE working on T-Mobile for their US996 while others did not (I'm still on a Sprint MVNO, so I won't be able to test this myself until T-Mobile completely takes over the network). But what's certain is that only the H910 can get VoLTE on AT&T (they keep a whitelist that determines which phones can get it), and LineageOS on pretty much any LG phone will likely never have it working.
So, at a minimum, you'll have to at least go back to a stock-based ROM if you plan on using a V20 next year on any carrier in the U.S.

I am not XDA savvy so forgive me if this is not what you are asking.
I have US996 factory unlocked ,I am on stock 8.0 and use Net10 which is ATT and do calling with LTE. which I assume is 4G.

What OP is saying is that the calls on AT&T and its MVNOs for a US996 are actually done through 3G/HSPA and not LTE, unlike cellular data. AT&T's own H910 is the only V20 model that can make calls through LTE (VoLTE) on their network. Once AT&T turns off the 3G networks early next year, calls will no longer work on the US996 and any phone that's not on AT&T's whitelist.
You should be able to see this on your phone: When making a call, the LTE icon will not stay up, indicating that VoLTE is not working.

Oh nifty this phone becomes more and more an issue. So now I ahve to add this to my plate. Seems like it will still be a year. OK but the US996 has LTE so why is this still a problem? Why wont it just use the LTE band?
Please be kind I do not know all the acronyms or how any of this all works.
Cant the US996 also run on Verizon?

Because of its whitelist I linked in the second post, AT&T actively blocks any phone not on the list from using LTE for calls (VoLTE = voice over LTE).
As for Verizon, they blocked direct activation of the US996 starting in 2018. You will see that entering your phone's IMEI number on Verizon's website will give you a message saying it's not compatible with their network even though it is perfectly capable. It may still work if you insert an already-active Verizon SIM card in there, but I don't use Verizon, so I can't say for sure if that still works.

Wow, talk about a way to force new contracts and phone sales. I never had a phone not be useable for PHONE CALLS. I guess I am grateful for the heads up as I was not aware and Net10 did not inform me of such things. I bought this phone because of specs and it was a removeable battery . But it seems this phone just was a pain from the start, with the screen issues, and the company claiming they would upgrade to Pie and never did.
T-mobile did not have useable coverage in my area when I tired it several years ago. So I really do not know what is going on since they now have Sprint.

Not sure if you're still looking at this thread but i have a v20 us996 factory unlocked and a G6 us997 factory unlocked and they BOTH get VoLTE on Red Pocket Mobile AT&T mvno. Calls DO NOT fall back to 3g or 2g and data stays active while in calls.
