For some reason, most of the cheaper Galaxy S4's for sale on eBay are from US Cellular. Can those be unlocked for use on GSM carriers such as AT&T?
Thanks

Nope. They are CDMA.

The verizon s3 had gsm capabilities after some tinkering (I think it involved flashing a different rom), so I was hoping the same might eventually be possible with the us cellular s4. Does anybody know if the us cellular is purely cdma and not possibly a world phone with hidden gsm capabilities?
I have seen a few galaxy S4 listed as I9500 from US Cellular. I asked the sellers about it and they say they don't know. But I9500 is a GSM model and US Cellular is a CDMA carrier.
US Cellular will not work on other carrier
According to this reliable source s4 US Cellular is strictly CDMA, not like Verizon counter part.

I know, this is an old thread but I like the old phones.
I can confirm that a US Cellular Samsung S4 Model SCH-R970 can make calls and do SMS on a GSM carrier (Verizon) in my case. My problem is 4G data isn't working, yet. Edit: I am able to get 3G data going, but 4G is not.
I recently picked up a cheap but perfectly good US Cellular S4 and was able to use my Verizon SIM to make calls and SMS. It appears that the phone is only set to CDMA so data with Verizon isn't active at this moment (I am using wifi). The trick to getting the voice and text working was letting the phone go through 5-6 system updates over the course of 5-6 hours yesterday over wi-fi. After the last one, the phone "unlocked" from US Cellular** and let me use my Verizon sim to make calls and send text.
**This falls in line with what it says here uscellular dot com:
"4G LTE Devices

Select 4G LTE devices (listed below) that were launched before February 1, 2016 are unlocked by installing the latest software update.

I always liked my S4 so when my S5 broke (dead screen) I picked up an S4 cheap. I can't stomach paying $200-800 for a new or ussed S5-S8 phone.
Does anyone know how to add the GSM settings into the phone so I can select that as my data network?? Currently the phone only displays CDMA/LTE as the choices.

Ah, OK then I stand corrected. Perhaps I am running a fool's errand here (trying to get GSM going).
Let me update the situation: my current status is that 3G data is working on the SCH-R970 US Cellular phone (with a Verizon sim) but 4G never kicks in. Maybe I just need to visit a Verizon store.

Yep, thanks. I attempted to do that. But I don't believe I the setting took hold.
Details: I used "Offline SIM APN" tool (from Play Store), and manually entered the settings that I found online for Verizon. The Os is now 5.0.1 and the tool says it can no longer add the APN automatically on Android v4.0 or higher, so I did it manually. It appears to be in the phone but I don't know how to activate it on the phone.

I managed to add APN in an old phone a few years ago by editing the build.pro file, but you need to be rooted in order to do that.
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 have done a bit of searching and haven't found what I am looking for.
I want to know if it is possible to run a Sprint Galaxy S5 on Verizon's Network.
Please give me a good reason if not, I have read that they use different LTE bands, is there a way to change bands? let me know. Thanks in advance...
Verizon will not accept any other phone. Only Verizon phones. Also Sprint LTE bands are not compatible with Verizon Network. So the answer is no you won't be able to use Sprint phone on Verizon network.
I have been doing research and searching these forums for a few days now, I'm trying to not be one of those people who ask questions that have been answered. But at this point I'm at the end of the road.
I bought a Sprint Galaxy S4, model SPH-L720.
I unlocked it using this method Sprint Galaxy S IV SPH-L720 SIM Unlock Method
Reverted back to MDC baseband and all that good stuff, just as instructed. It seemed to have went well without a hitch.
My question now is:
I want to buy one of these Verizon 4G Sim Activation Kits from walmart
Is it possible that I can buy one of those, insert the SIM into my unlocked Sprint S4, and have a working phone? I ask because I don't want to drop $50 if it doesn't have a chance of working. The instructions for this say that it will work with a VERIZON S4, but since my SPRINT S4 is unlocked, should that be okay?
I don't know much, but in my reading I found that Sprint and Verizon both use CDMA, not GSM. So I figured I had a better chance of this phone working if I go with Verizon because of this.
I am in the United States.
If you need any other information or screen shots please let me know, thank you for taking the time to help me out!!
EDIT: would it be possible to test it out, if one of my friends has a verizon phone under contract, and I took their SIM and inserted it into my phone?
Try it.
Like the guy above me said. Try it. One way to find out. Personally I don't think it would work. As the whole point of unlocking the sprint Gs4 is to use it on GSM networks. From what I know you have to flash the sprint phone to Verizon. Plus you WONT get LTE on Verizon because the bands are not supported. So you'll only get 3g.

thank you for the info! i'm just learning about all of this, so i don't have a firm grip on everything yet.
in the tutorial i used and linked above, the file I used with Odin was actually titled "S4 Flasher", so I believe I unlocked it and flashed it with this? Again, Im sorry, Ive tried searching and am just looking for verification if Im correct.
I'm not worried about LTE, 3G is fine really. Also, I'm not set on Verizon, I just want my phone to work, doesn't matter what network I'm using. If it would be "safer" or a better bet to get into a GSM prepaid, I will do that instead. I was just under the assumption (incorrectly probably lol) that since sprint is CDMA, that going to another CDMA carrier would be easier.
Cricket, Net10, StraightTalk, and AT&T etc are all available at the store I think if I go GSM
Again thanks for taking the time to help everyone!

I unlocked my sprint GS4 and went to Cricket. And I've been happier than when i was with Sprint (service wise). I have signal in 98% of the places I go to. Which is a HUGE improvement over sprint. And even though this phone only connects to HSPA+ which is capped at 3.5 Mbps its plenty fast for all my daily activities. So I recommend a GSM prepaid.
Hello, I'm a bit new to all this, so please bear with me if I sound a bit out of the know. I currently have a SM-G935V, from Verizon of course, but I recently switched to AT&T as they have better service for me, however, the best connection I seem to get at the moment is H+ (it switches from 3G to H and H+ but I know for a fact that there is 4G LTE in my area). Not sure exactly what to do in order to get consistent 4G LTE. I have called to troubleshoot with technical support; we set up a few APN's, but to no avail. Would flashing the SM-G935U firmware help me at all, or am I doomed from the start since I have the Verizon variant (they claim that all of their LTE phones are unlocked)? Also, I heard that for the US version of the phone they will not let you flash anything on them. Is that true? Thanks for any help or advice in advance, I greatly appreciate it!

I'm not 100% sure AT&T is included but you can try following the instructions and flashing Jrkruse's U Firmware ROM here: https://forum.xda-developers.com/verizon-s7-edge/development/rom-t3603231

Thanks! Just an update for anyone who reads this thread having the same problem. Flashing the U firmware did in fact do the trick, but sadly I am not getting HD calling. Data works on LTE just fine though.
