is my phone CDMA or GSM? (G900P) - Galaxy S 5 Q&A, Help & Troubleshooting

the reason i ask is because i used idoneapps to unlock and i have tested a CDMA sim card and it does work but i bought a GSM straight talk sim and it also works. (even says connected to T-Mobile network and tells me to dial 0 for new voicemail. But straight talk told me (rather rudely) that it is only CDMA and will never work on their network because of this. but T-Mobile website claims it is fully supported. so what is it CDMA or GSM??

I don't have these variants myself but, the following link reflects the comparison between the SM-G900P and the SM-G900T.
https://www.phonemore.com/compare/p...m-g900t-vs-samsung-galaxy-s5-sm-g900p/4560371
Technically they share the same GSM Quad Bands for Cellular Calling but, the 2G-4G LTE bands is a different story because the SM-G900P is primarily a CDMA and the SM-G900T is primarily a GSM.
In order for you to get both the Voice and Data service for your SM-G900P device, you'll have to stick with the Sprint & Verizon Towers because they are both CDMA.
The SM-G900T is GSM that is capable of using the T-Mobile & AT&T towers (as well as a handful of overseas towers too).
I hope that I had explained this okay via text...

thats interesting. verizon says my phone is not compatible. say i were to flash the modem with G900T modem firmware through TWRP would it brick or or allow the same bands? i was told that s5 for the most part shares the same hardware as the rest but is soft locked by vender

You shouldn't flash any Firmware Modem Updates that are not specific to your device. This can cause problems even if you were to succeed. Meaning that The Firmware Modem Update file has information in them that Odin uses to confirm that it's for your device.
If you had the LineageOS for the klte device installed and placed a SIM for the Verizon Towers into your device (Since the klte is also for Verizon as well), the Firmware should be able to see the Verizon based SIM and obtain the appropriate PRL listing within LineageOS.
I can't guarantee this but, it might work...
You can always try to obtain a second opinion for the above information from the following S5 Q&A thread or the following klte LineageOS thread.
https://forum.xda-developers.com/showthread.php?t=2700073

I would recommend asking for a second opinion since this is theoretically possible but, it doesn't mean that it is actually possible.
Good Luck!

Unlock S5 From Sprint To Tmobile?

I recently got the S5 on sprint and im beyond disappointed with sprints new spark and lte network out here in NY. Im considering going to Tmobile since there lte speeds are crazy good and connection is steady out here. My question is can i get my phone unlocked and bring my sprint version phone over to Tmobile? I was told by a Tmobile rep that my phone would go down to 2g speeds and its not guaranteed to even get lte. Which i find hard to believe since since my phone has the option to also go on GSM/UMTS. Whats your guys thoughts on this?

Correct. Sprint uses different frequency ranges, so unlocked or not it's just not going to communicate.
ATT and T-Mobile work due to the overlap. In fact, for a while there ATT was going to purchase T-Mobile before the FCC put a halt to that.
Glad too as T-Mobile is now shaking up the market and forcing (encouraging?) Verzion and ATT to try and adopt similar measures in order to maintain customer base.

I dont think this is correct. Albeit S5 is a different phone, but I unlocked 4 SPH-L720 S4's from Sprint to Tmobile no problem using the following thread: http://forum.xda-developers.com/showthread.php?t=2530610
If S5 could use the same methods, you would get 3G and HSPA+ on the Sprint S5 using a TMobile SIM.
I was able to get LTE using a TMobile SIM on a Sprint S4 by using DFS to edit the NV to enable AWS 1700 LTE Band in NV items, then flashing the TMobile HOS and MODEM bin files - along with copying the *ril*.so libraries to the system/lib directory. This ultimately allowed me to select the LTE/WCDMA/GSM option in Mobile Networks.
Not many people know about this but I found it in an i337 thread on how to unlock AWS on a S4.

So you can get full speeds on gsm networks with the sprint version? in the US or out?

Has anyone comfermed this? To my knowledge the Sprint/Verizon phones are not cross compatable with AT&T and T-mobile. Some verizon phones are the exception but basicily its a no go from CDMA phone to GSM tech.
confirm
i can confirm the sprint s4 does work on tmobile with a bit of editing and following the gsm domestic tutorial on xda, however this part about the modem.bin and hlos isnt confirmed and i have done this and ended up hard bricking my devices and had to jtag to repair them. ive tried many times and always bricked so i say no go.
this forum is for the sprint s5 and i would hope we can find a loophole to get it gsm unlocked. any ideas? ive tried a few things but no luck
Theres alot of incorrect information here. The latest Sprint phones using sim cards ARE ABLE to use T-Mobile and AT&T as long as GSM is in the hardware. I dont own the S5 but for those blinding others with frequency talk I'm tired of seeing, read it and weep:
http://www.phonescoop.com/phones/phone.php?p=4408
Sprint S5 supports GSM. Now of course no LTE on T-Mobile due to the lack of the 1700 frequency,
but your 4G will be fine. Depending on where you live, you may not even care about LTE over 4G.
Sure, Sprint locks the darn thing up to avoid it getting into the hands of other domestic carriers, but
just as the Sprint Note 3 and my Sprint LG G2, a workaround has been invented. For the G2 it was as
"borrowing" the stock T-Mobile LG G2 firmware and tweaking it to boot up on our LS980. We have
about 3 different tastes of working unlocked roms, not only sticking to T-Mobile, but other carriers
reported working such as Metro PCS and AT&T. So my guess is that the S5 may need a similar
treatment, nobody wants Sprint honestly. The first 14 days (brought in my own LG Optimus G LS970)
I was with them service was glorious here in NYC. But after the 14 day "trial period" ended I was
DAMNED into horrible service, constant 3G instead of 4G, etc. Thanks to refusing to make payments
due to the disgusting service, my GS4's IMEI is basically crap, so I sold it in the same week I got it.
I should have never swapped it out for the LG OG...
Honestly, I'll thank every OP I see that "unlocks" the Sprint version of any phone for domestic GSM
use. Their silly Sprint Spark is useless, why introduce something new when they dont even have full
4G coverage here in the USA? And their agents sound like "AI" controlled cyborgs: "Oh we're sorry to
hear that, your zone is scheduled to be recieving 4G soon." Yeah right. I feel sorry for those who suffer
in other states.
ANYWAYS sorry for drifting off topic. The recap here is that the Sprint S5 IS capable of domestic GSM with some modding.
And also that I hate Sprint.
Any Updates on this
Does anyone have any news on this? I have a S5 from sprint and want to use it with tmobile or other gsm carrier. any1 have any updates on the UCCI deal i read about somewhere? I have the spc phone is rooted what do i need to do? cant bring up the service menu to change things there.. kind a lost pls help
..
lease has anyone found a solution for enabling aws bands on galaxy s5? i have the at&t active version unlocked and rooted using on tmobile but i get only edge :/
What is the verdict? Is there anyone who knows you can use it on any network? I am getting mine tomorrow and am unlocking it. Is there a way to test if they will work on any network? I have many sim cards from diff carriers.

There have been a lot of threads about this, so clearly few are even bothering to search the forum for existing threads and the wealth of information in them.
Sprint is a CDMA system like Verizon & USC. CDMA per se is incompatible with GSM, which is what most of the world uses. The Sprint S5 only supports some of the most common GSM frequency bands and moreover will have a locked bootloader and SIM.
Sprint will not unlock the SIM (actually SPC code) to allow using it with other domestic carriers. You can find third party vendors that will "SPC unlock" your Sprint phone. But then you will find that Sprint's S5 won't support any of the LTE bands on other CDMA or GSM carriers and misses some GSM bands too.
Nor can you use custom ROMs, kernels or recoveries in the normal manner due to the locked bootloader. You could probably use the Verizon Safestrap method to emulate a limited palette of custom ROMs, but you would have to do your due dilligence there and look into the details.
In short, if you jump through enough hoops, you can use a Sprint S5 on another carrier like TMobile. But it will always be marginal. You won't get LTE data speeds, you will see more congestion than those using native handsets, due to your reduced number of bands. And you may have no coverage at all in some fringe areas served by a TMB band that your handset doesn't have.

The limitation of what "bands" the radio will cover are software defined. if you look around. you can find a way to modify those defined rules.
to allow it to use 1700 LTE. although the legality may be questionable as the FCC approval for that model was not tested with the LTE. The baseband chip/radio still supports the band with the software changes

What in the heck? Who fed you this bologna? Do you work for Sprint? Cause I have various complaints for you if you do. My SPRINT G2 running a T-Mobile G2 stock rom which is unlocked DOMESTICALLY works perfectly fine with T-Mobile's 4G. I don't think many people care about LTE, getting off of Sprint alone is a huge leap for mankind (in this case G900P owners). And as it was mentioned, there are ways to get that nice LTE band for various devices with simple mods, problem is that it is NOT widely recognized yet and very few people know that the possibility exists because of various misleading posts that "its all in the hardware" and fingers being pointed at Qualcomm's techniques. Yes there is a possibility for a domestic unlock, sure there might not be LTE for it, but most people will be content with the fact that they can use their expensive locked down phone with another carrier. Honesty Sprint devices would be better off being sold for less than carriers that actually DO allow domestic unlocks. Why do we pay over half a "K" for a phone that in reality we do not completely have full rights over? Why do other carriers alow domestic unlocks and Sprint wants to be greedy and lock in all of their customers with shady contracts and decieving bills?
Thats why many of us including myself would be beyond grateful if we even get some 3G with another carrier. We have CDMA capabilities, we have GSM capabilities, all we need is some sort of domestic unlock.
There is NO third party unlock code of any sorts that will unlock a phone that is unlocked OTA. Check around for many posts from various foreign users who have gotten stuck with a useless Galaxy S5 that can only be used with wifi thanks to Sprint. Is it their fault? No. It is purely Sprint's fault for being so damn greedy. Thankfully I am hearing news that by February of 2015 all devices will be GSM and have the capabilities to be unlocked for domestic use.
Custom roms, honestly most of us are just unsatisfied with the average and like to go to the unique side. But is Cyanogenmod going to allow us to use Air Gestures and all the other cool features of the S5? Not really. Custom kernels would be nice, but many people only seek then in order to overclock their device, which this device is in particular really doesn't need any more added power (or battery drain) than it already has. Optimization tweaks might be worth it but I dont see it helping. If someone could fix the delayed multitasking transitions (switching from one app to the other at times is delayed a second or two) or the crashing browser without custom roms or kernels, then it is best not to waste time on the development of such things. But then again there are those who prefer stock android in combination with other features such as the AMOLED screen technology, but it is best to look for another device.

[Q] SM-G900F (belgium) 4G possibility in USA?

Hi guys, i have an S5 bought unlocked in belgium, europe. I had 4G in europe but in the United States it only receives H+. I checked the supported bandwidths with tmobile usa, two of the bands tmobile uses are in fact also supported by my phone (1800 & 1900) yet still it doesnt work. APN setting are already checked and confirmed correct. Sim card is brand new.
Since it still doesn't work, is there a way to flash a USA rom or upgrade something technical so i can get 4G? I would hate to have to buy a new phone again, i just bought this 4weeks ago thinking it would work globally
Thanks again for recommending the best possible option for me at this point...
Most of your questions here were posed and answered in your other thread.
Your 900F model phone is intended for use in a different country. TMobile uses a 900T model. The main difference between the two is that they support a different set of frequency bands. So just like roaming you could use your 900F phone on TMB, but there will be gaps in coverage. You will be subject to more congestion and dropped calls. And in smaller centers where a limited number of frequencies are in use, you may have no coverage at all.
If you never get LTE in a major center on your unlocked 900F, the first thing to check is that you have a LTE capable SIM and that your carrier i.e. TMB has provisioned your account for LTE. And try installing the latest version of firmware for your phone.
No, you cannot simply flash a 900T firmware onto a 900F and have it transform into the other model. By design, Samsung doesn't allow this (to sell more phones and deter carrier churn). There is a hack to add the AWS band to some models. And several threads endeavoring to expand upon that. However they are nascent and would be best described as experimental, dangerous (a good chance of damaging your phone) and with uncertain results as of this date.
Unless you want to put your phone at risk to be a guinea pig, your options are to live with the imperfect coverage or buy a 900T model.
If you want to take a risk, then have a look at this thread. And here. Basically you could use QPST or mzTools 1.21.a to format an edit NV_RF_BC_CONFIG_l to enable additional LTE bands. Enable the parameters with QXDM, then do the actual write with QPST. And /or try writing a raw image of an LTE enabled variant e.g. 900T baseband to your 900F modem partition with the dd utility. This is experimental. It may do what you want or it may brick your phone.

Oké so turns out i am getting 4G just not LTE because of the state i am in. Thanks for trying but what i initially said was correct all S5s are global capable of 4G, just state dependant on the LTE band...

US Cellular Note 4 SIM Unlocking

Hey all,
I recently got my Note 4 through US Cellular SIM unlocked and when I insert another SIM from AT&T or Tmobile, the phone accepts the SIM but there isn't any setting to change the phone to global mode in the network settings area, nor is there a way to change APNs. I cannot place calls on either Tmobile or AT&T with it, which I find odd since the phone doesn't reject the SIM. Does this version not have support for GSM bands or is it something to do with US Cellular's software that prevents it from connecting to United States GSM carriers? Is there a hidden setting that I need to get into to enable GSM use? Thanks all!

I also have bought a US Cellular Note Edge (not arrived yet) to use it in European GSM Networks. Phone was really cheap, so i thought i'll give it a try. Anyone have news on how to unlock GSM capabilities on this ? Maybe with a Rom from a GSM Edge ?

I recently spent some time on the phone with the executive assistant to the president uscellular and well I had no success in getting my phone unlocked if I understand correctly the phone is cable of gsm also. If anyone would like I can give you the number 4 this lady name Karen and you can bring her directly. I also spoke with several members of the presidents executive Support technical service and they all indicated that the machine would have to be taking it into the store to be unlocked. the weird thing was that the machine is not blacklisted, stolen nor gained in any ill gotten way but yet all with one accord further said that it would be refuse for unlocking without giving any good reason. I understand the company was sued in court and lost the battle to not unlock their phones and this seems to not affect them only one to one basis. I will find a solution to this and I will share it. I would be grateful for any help in doing meanwhile.

Hey, everybody. I hope I'm able to help... and in turn, I hope someone is able to help me.
Supposedly... newer Qualcomm-powered Android phones are inherently capable of connecting to any CDMA or GSM network. However, the different bands are enabled/disabled per the carrier's specifications. For instance, I'm a Verizon customer, and I connect to bands 4 and 13 for LTE service. However, US Cellular devices do not have band 13 enabled by default.
All hope is not yet lost, though. There is a thread (which has since been closed due to trolling/bickering) that details a method to flash the Qualcomm chip to enable/disable bands as needed. See here: http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059 According to the information there... it seems that I'd be able to flash the CPU chip to enable band 13, and then I'd have support for all 1x / 2G / 3G / LTE bands that I'd need for Verizon. Likewise for T-Mo, Sprint, ATT, etc.
Now for my problem...
I have recently purchased a USC Note 4 (N910R4) from Amazon, though it was listed as a N910F, International Edition. It was listed as having been unlocked for use on any CDMA network. Unfortunately, the phone does not recognize my Verizon SIM, Verizon couldn't give me any information about the device, and a US Cellular support chat representative said I'd have to visit a store to check if the phone is actually unlocked. The closes USC store is several hours away in another state. The phone came with a USC SIM still in it... and it recognizes that SIM without a problem. I can't make phone calls, though... and no mobile data, either.
I had intended to use the International Version (N910F) and enable the correct bands per the thread above... and then activate the phone on my Verizon account... but the USC version should be close enough in band support that I'd be able to at least activate the phone. The USC phone supports band 4 LTE, and I get band 4 service where I'm sitting right now. If not that, the 2G and 3G band support are identical, I believe. So, I'm just doubtful that I'll be able to activate the phone just yet.
Can anyone shed light on how to verify that my new phone is actually carrier/SIM unlocked? I was hoping I'd be able to get someone to query a database of unlocked MEIDs, but for some reason, I am supposed to go to a store. I can't even call.
Any help is appreciated.

I share all your concerns sir. I too have not learned yet how to determine if USC nope for exactly carrier locked or no but I am of the firmest belief based on what I've learned from USC at various levels up to the Presidents executive team that it is indeed carrier locked. I cannot answer for yours then I believe that all under phones come in one of the two varieties and I am convinced even after the court ruling against them that they I have no intent to unlock a phone by less than forcesure. Furthermore I have no confidence that the store they may send you to has any unlocking abilities. According to the executive team that does this work in reality you must in the machine into them and prove its worthwhile to be unlocked. In my case well they cannot prove there is any malfeasance, they still choose to err on the side of caution and refuse to accept any proof then I have of the machine purchased new complete and clean but from a second party. They furthermore refuse to contact the locals that originally sold the phone and truthfully are the first corporation that ever more me so thin that I chose to unlock the bang bang myself. I remain as giddy as a schoolboy hoping to hear more good news from this post. I'm confident then I currently have the knowledge to fix the phone but do not currently have the time. I will happily update I'll with my success be crying the Blues at my failure soon.

Any updates, guys? Did flashing the ROM to allow access to additional channels work for anyone? Thinking of buying a USC Note 4 and then trying to unlock it for GSM usage.
Any news on unlocking or using on GSM networks? thx
kardeşim ne yaptın telefonu açabildin mi ?
aynı sorun bendede var
Has anyone got any further with this? I've just bought a US cellular note 4 and my APN settings are greyed out. I'm assuming that US cellular will be difficult to deal with to get the phone unlocked especially if it has been bought from a third party. Has anyone had any luck with getting there's unlocked?
Hi!i set my Note Edge to say on Network mode:GSM/WCDMA/LTE but i can't place calls etc...has anyone an idea to make it work?
use z3x box to unlock it
To whom might be concern;
Make things short, NO, you cant use USC Note 4 on any US carrier if u look at the spec. The phone support only some GSM850 and FDD LTE band 5 (850mzh). And att/tmobile 2g voice is on gsm1700/2100 and LTE band is not match....... So that being said you are buying note 4 as Samsung Player and only good with USC and somewhat Verizon(need to hack for it to work, and stillike not all feature will work). Hope answer most you guy question

Hey, everybody. I hope I'm able to help... and in turn, I hope someone is able to help me.
Supposedly... newer Qualcomm-powered Android phones are inherently capable of connecting to any CDMA or GSM network. However, the different bands are enabled/disabled per the carrier's specifications. For instance, I'm a Verizon customer, and I connect to bands 4 and 13 for LTE service. However, US Cellular devices do not have band 13 enabled by default.
All hope is not yet lost, though. There is a thread (which has since been closed due to trolling/bickering) that details a method to flash the Qualcomm chip to enable/disable bands as needed. See here: http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059 According to the information there... it seems that I'd be able to flash the CPU chip to enable band 13, and then I'd have support for all 1x / 2G / 3G / LTE bands that I'd need for Verizon. Likewise for T-Mo, Sprint, ATT, etc.
Now for my problem...
I have recently purchased a USC Note 4 (N910R4) from Amazon, though it was listed as a N910F, International Edition. It was listed as having been unlocked for use on any CDMA network. Unfortunately, the phone does not recognize my Verizon SIM, Verizon couldn't give me any information about the device, and a US Cellular support chat representative said I'd have to visit a store to check if the phone is actually unlocked. The closes USC store is several hours away in another state. The phone came with a USC SIM still in it... and it recognizes that SIM without a problem. I can't make phone calls, though... and no mobile data, either.
I had intended to use the International Version (N910F) and enable the correct bands per the thread above... and then activate the phone on my Verizon account... but the USC version should be close enough in band support that I'd be able to at least activate the phone. The USC phone supports band 4 LTE, and I get band 4 service where I'm sitting right now. If not that, the 2G and 3G band support are identical, I believe. So, I'm just doubtful that I'll be able to activate the phone just yet.
Can anyone shed light on how to verify that my new phone is actually carrier/SIM unlocked? I was hoping I'd be able to get someone to query a database of unlocked MEIDs, but for some reason, I am supposed to go to a store. I can't even call.
Any help is appreciated.

Though the phone is automatically cdma unlocked on android 6.0.1 roms, the bands are still disabled. I suggest following DrPhant0m's advice and look into the posted link above.

I've still got the USC Note 4. My son uses it on wifi and to watch videos that we load to local storage. In other words... no sim card installed.
If I manually update the phone to 6.0.1... what will I gain being that I'm a Verizon customer? Is the only difference that 1 band of LTE will be inaccessible? Would it actually start working for calls and some data with a verizon sim?
The whole "reprogram other-carrier Qualcomm phones to work on Verizon's bands" is frequently debunked as chasing a unicorn in the verizon forums.
Further... is the same applicable to newer phones? Could I get a newer (note 5/7) USC phone with android 6.x+ to work with verizon? (Unlocked bootloader would be my only reason to try)
Thanks!

Root Possible on Verizon 5.0.1??

I have a Samsung Galaxy S4 on Verizon (SCH-i545) running Android 5.0.1. I cannot find a way to root after searching and searching threads and online! Please help!! Would love to root this phone.
Sent from my SCH-I545 using Tapatalk
Did you look in the Verizon S4 forums? That is where you want to go for answers to your questions, as this is the international S4 forum, and we don't have a locked bootloader to prevent root.
Looked there, but didn't find anything. Maybe will post this there, thanks for your help. Can you explain locked bootloader or send me a link of a thread that does? I don't understand the difference of the international.

Actually I see that someone moved this thread to this category... I posted it elsewhere, what should I do? Noob, sorry!

Go back to your opening post and report it to the mods. In the text box that appears simply tell them it needs to be moved to the Galaxy S4 Verizon forums. They'll take care of it.
With a locked (i.e. encrypted) bootloader, rooting cannot be performed and custom ROMs cannot be installed. AT&T and Verizon are the largest of the carriers that do this, and they claim to do this in order to ensure consistent performance of the device on their networks. The reality is that they simply don't want you getting rid of their bloatware or working around their other restrictions by rooting and installing custom ROMs. International devices don't come with locked bootloaders, and customization is easy. However, an international phone in the US doesn't get LTE due to the international device not supporting the frequencies used in the United States.
In the US, if LTE is important, a T-Mobile device is the best option even though the device never received an upgrade to Android 5.x. But if you take it abroad, LTE will not function due to it not supporting international LTE frequencies. To the best of my knowledge, phones that support both sets of frequencies have yet to be released.
Thanks for your helpful reply! So... My provider is Verizon, if I get a "T-mobile phone" will it still work on Verizon's network and he rootable? There is some difference in Verizon and AT&T I know because Verizon and Sprint are CDMA and AT&T and others are GSM networks right? I'm not sure what all those mean, but I didn't think they were interchangeable. I thought T-mobile was GSM, but maybe I'm wrong...

You'd have to leave Verizon if you want a phone you can modify. Verizon and Sprint are CDMA networks, while AT&T and T-Mobile are GSM networks. GSM is the global standard. A CDMA device won't work on a GSM network and vice versa.

How to enable GSM on GS7 (Smg930v)?

Hi,
I've found someone in Brazil who is selling a Verizon GS7 (smg930v) at a great price but he claims that it's not working here because it won't recognize the Brazilian mobile network (the bought the phone in the US). He says the phone connects to the 4G network but he is not able to navigate or make phone calls. I find this weird as I've read in many places that Verizon's GS7 are unlocked to work on GSM.
Any thoughts on what can be done?

It won't connect in Brazil because they are GSM-only; whereas VZW is a CDMA-only network. South America is like the EU - mostly,l if not entirely, GSM-only; VZW and Sprint are using different (and not cross-compatible) types of CDMA. Tracfone (and their Safelink lifeline division) is an MVNO that uses T-Mobile and VZW towers for coverage (and thus support both GSM and CDMA phones). Tracfone has both GSM and CDMA SIM kits - however, the SIM kit you purchase must match the target phone. (Some phones, such as the Galaxy Nexus, for example, are available in both sorts - maguro for AT&T Mobility and T-Mobile/Deutsch Telekom, and toro/toroplus for VZW and Sprint; there are even "unified" ROMs (the Tuna versions are neutral in this fashion, and are available from JB to N - PureNexus 7.1.1 for Tuna is my default, and is just one such example). It may be possible to modify the radios to support GSM bands; however, I would not recommend it.

you do know that almost all Verizon phones now are unlocked out of the box no mods needed

mine is a Verizon on att rite now no mods at all other than root and stuff

sorry for double posting kinda thing here
the reason its connecting to 4g there is the phone supports the 4g band obviously in brazil
but not some of the others I had this issue with my note 5 not supporting atts 4g band so I would get 2g and 3g but no 4g
again flash the g930u firmware and it seems to unlock all the bands

You should be able to put in the GSM sim and set the APN to what the carrier recommends and it works. It may not support all of bands that that carrier uses but it should work. You could also flash the Verizon SM-930v to the firmware for the Unlocked SM-930u via Odin and unlock more of the GSM bands. Most like it is just a APN issue

You have no idea what you are talking about. All Verizon phones are sim unlocked and since the HTC Thunderbolt, they all support a lot but not all GSM bands. All newer Verizon phones are world phones and usually just need the proper APN of the Telecom being used. Again they do not support all GSM bands but the do cover a lot of them that are used internationally.

I will second both of these post in every way. Lol. I was thinking it just tryin to keep to myself
Agreed. You could purchase the phone and flash the U firmware. That's what I have done. I have used my Verizon s7 on Att and TMobile through their mnvos respectively
To wrap up in a nutshell what everyone else was saying...
1) The G930V S7s have both CDMA and GSM radios, so will work on both types of network.
2) Verizon phones are NOT network locked.
3) You need to check the GSM frequencies for your local network. The G930V uses GSM 850/900/1800/1900 for 2G & UMTS 850/900/1900/2100 for 3G. If your local network doesn't use any of these bands, the phone won't work for calls/SMS.
4) Flashing the 'U' firmware will only add UMTS 1700. There used to be a way to get into the radio settings and add/remove frequencies using a service code, but I believe that Samsung have locked down that ability.
Great info
Great info!
