Sprint/Verizon Moto X

I would love to get a Moto X that has 64 GB and an unlocked boot loader.
Is it possible to purchase the Sprint Edition of the Moto X and convert to a Verizon Moto X to work with LTE?
Before this becomes a "My Carrier is Better Than Yours," due to my location, Verizon is the only carrier I can use.
Thanks!

No. The Sprint variant does not support any bands that VZW uses for LTE. You will get (at best) only 3G, and it will be quite a process even getting it to work on Verizon (if you even can). Currently, AFAIK, people have only been successful flashing the Sprint variant to MVNOs such as PagePlus. Sprint is currently the only carrier that uses LTE on the 1900mhz band (and this is the only LTE band it supports). This makes it only useful for LTE on Sprint.
Your only option is the Verizon variant if you want to use VZW, and I would suggest you buy the VZW DEV edition if you want guaranteed bootloader unlock.
Good Luck

Beyond the LTE bands being different, does the sprint X even use the same 1XRTT/EVDO bands and settings as Verizon? This will be a challenge getting that part even working.

Yes. The Sprint variant supports 1X, and EVDO/EHRPD on both 800 and 1900. Sprint has a roaming agreement with Verizon....
I own the RW Moto X (identical in every way to the Sprint variant except firmware - even the same FCC ID), and in areas where no Sprint service is available, it will roam to Verizon on both 1X and 3G (EVDO), but (of course) not LTE. RW is the only Sprint MVNO (that I know of - possibly the only one period) that allows roaming to Verizon.
Remember: PagePlus is an MVNO of Verizon, and people have successfully flash the Sprint variant to PP.

You could get 1X and 3G/EVDO, but that's it.

Thanks for all the advice.
I'll just hold off for the X2 (X+1), or just be happy with DE 32GB of Moto X.

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!

Old thread but bumpin, any news on this?

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 am having the same problem

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

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

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!

I'm pretty sure the International (GM935F) version does NOT support Verizon's CDMA.

Verizon and sprint are the only reason USA doesn't have the faster exynos processor.

I'm also interested in this. I'm thinking of buying a G935F so I can root and have complete control over the recovery and ROMs.
I assumed the international (global) variant would support everything. My Galaxy S5 works everywhere including the US and also drops to 3G if necessary on Verizon. The ultimate question is, if I buy a G935F, can I make/receive calls, texts/mms, and get data using a Verizon SIM card? If I'm in a fringe area and it drops 4G, what will happen? Will it just have no service? I have to think it would support 3G/2G. If a person from Europe comes to the US with the G935F and uses a verizon SIM or is in a verizon only area, they would be screwed.
Again, I would think it should just work, no?

It will not work on Verizon because
1. Verizon relies on using the outdated CDMA standard so you can't connect to their "3G" network.
2. Verizon uses non standard version of the VoLTE IMS (so does T-Mobile it seems), so you can't place calls over LTE even if you flash a VoLTE enabled firmware on your GS7
3. Verizon as a carrier is a control freak that doesn't let its costumers use devices that have not been "approved" by their services, therefore, your devices' IMEI have to be white-listed in order to connect to their network.

Already started the process of moving to AT&T...waiting on my work to confirm it. I hope Verizon reads this. It would have been some much simpler if they just unlocked their bootloader and didn't put a ton of crap (bloat) on their stock ROM...then they would have retained this customer.

I was considering the G935FD (dual sim) since my personal phone is AT&T and my work phone is Verizon. I want to consolidate to a single phone. Honestly I only need Verizon for calls and text, not even data, since my AT&T is unlimited. Looks like the international S7 Edge support Verizon's primary LTE band 13 which would technically work for data, but won't connect to their CDMA calling network according to mathieulh.. Now here's the kicker.. the new ZTE Axon 7 is supposedly compatible with Sprint and Verizon, AND it's a dual SIM phone. I know Verizon has to give the final "okay" to have a device activate on their network, but looking at the specs between the Axon 7 and the G935FD (dual sim S7 Edge) on GSMArena, there are essentially NO DIFFERENCES between 2G/3G/4G(LTE) bands between the two devices. The only difference I really see is Cat 6 LTE (300/50Mbps) on the Axon 7 and Cat 9 LTE (450/50Mbps) on the S7 Edge.
Can anyone clear this up? ZTE is literally saying their Axon 7 will work on Verizon, with essentially the same network specs as the S7 Edge international... there MUST be some major defining issue with using the Exynos vs Qualcomm processor when it comes to CDMA connectivity, but I still can't see a spec difference online.

G930f won't work on Verizon
Hey guys so I see this last post is from almost 3 years ago but I like the s7 and I have verizon. I don't like the Verizon variant of the s7 and wanted to try this one, the g930f because it had the same bands for LTE that verizon uses. I thought I could just use Google voice and make calls with data. I've been messing around with it for a few days now and I'm using a pre-registered sim from a Motorola that I bought from Verizon. I cannot get it to register even with data alone. I've tried removing all AP names and then creating several different AP names using Verizon settings. It's a no-go. I'm getting the g930u.
Thank you for reading. Maybe you know a workaround?

Dual CDMA sims?

I was curious if anyone had tried dual CDMA carriers on their dual sim G4s. My understanding is that for 3G cdma voice the device itself is registered as opposed to a 3G GSM which registers the sim, so only one CDMA service could be active at a time. Changing to another CDMA carrier would mean going through Verizon's or Sprints's activation process each time you wanted to change to a different sim (this was my experience with a 3 sim adapter). I'd love to hear someone more knowledgeable chime in on this subject and provide some feedback on whether or not this is how it would work with a dual sim moto G4.
I'd love to have dual CDMA sims because I have free service with ringplus (Sprint MVNO) but it's spotty in rural areas, whereas Verizon has the most solid signal in the remotest regions.....however I think it's a pipedream. I am aware that you can do a CDMA LTE sim switch and get data without a problem (I'v done this with a triple sim adapter), it's voice and text that I'm interested in being able to switch to, without having to go through the activation process. And because I need this voice and data in remote areas without LTE, VOLTE isn't an option.
I hope that isn't too convoluted or arcane a question, I realize it's not a common scenario. But with the Moto 4G being carrier friendly to all the north american providers (GSM and CDMA) and having a dual sim slot, it's the first plausible solution to what I'd like to achieve.

Unfortunately, the only G4 models that have CDMA are the US models (XT1644 G4+, XT1625 G4, XT1607 G4 Play, XT1609 G4 Play for Verizon Prepaid), and the US models are only available in single-SIM format.
From what I've been gathering, there are no dual-SIM CDMA phones that fully work with US carriers available yet. The OnePlus 3 comes sorta close, it's dual-SIM and has CDMA Band 0, which Verizon uses in most markets, but at the moment it either works in 1x/EVDO mode for calls/text, or LTE mode for data. However, it's lacking CDMA Band 1 (Verizon & Sprint) and CDMA Band 10 (Sprint), so it's not ideal. It's also lacking Verizon's main LTE Band 13, and all of Sprint's LTE bands.
Slightly good news, though. The upcoming ZTE Axon 7 is dual-SIM and FCC testing indicates that it fully supports all US carriers, including all Verizon and Sprint CDMA bands.

I'll keep an eye on it.
Would the concept work the way I described in the first post though? I'm really curious if the phone would require sprint or verizon activation when switching cdma sims. I don't have a great deal of experience, simply my results with a multisim adapter. I was unable to test the adapter with a verizon and sprint capable phone (like a nexus 6) but tested it with an Verizon samsung s5 using gsm sims and a verizon LTE sim. The gsm sims (various at&t and t-mobile MVNO) were of course no problem, but switching to (or back to) a verizon LTE sim required teh verizon activation process (but not for data, as the LTE was active without activation).
Is it possible to have a dual sim (or even single sim) phone that supports both carriers (Verizon and Sprint) that could switch back and forth, or is the activation process simply inherreient with the way the devices imei's are registered on CDMA networks, and will always be required. For me going through the activation process for Verizon or Sprint when switching sims would simply preclude any practical usefulness with a dual sim cdma capable phone (although it would still have value as a dual sim with a cdma and a gsm sim).
Sorry for the late reply xtermmin and thanks for the info.

I can't speak for Sprint, as I have Verizon, but I do know that they're more restrictive than Verizon.
On Verizon, the only current restriction is a whitelist when you try to activate a SIM for the first time. You have to use a device that's in Verizon's "activation database", typically Verizon-branded devices, iPhones 6 and up, the Moto X Pure, and (at some point, if not now) the Moto G4 lineup. Once you have an activated SIM, you can stick it into any compatible device (be it from Verizon, another provider's phone, or even an unlocked phone that doesn't officially work on Verizon) and you should be good to go.
For example, I've been using my same Verizon SIM that I got with the HTC Thunderbolt (when it launched in March 2011) in numerous other phones (Verizon phones, US Cellular phones, unlocked phones, even some GSM/LTE-only phones) with no need to contact Verizon or use the website or anything. I've been able to just pop in the SIM, adjust the connection method on the phone if needed, and go.
As for your experience with using a dual-SIM adapter on the Verizon GS5, it might be due to the phone going into "GSM/LTE" mode when you insert a ATT/TMO SIM, but not switching to "CDMA/LTE" mode when you switch to your Verizon SIM (thereby only connecting in LTE mode). Might want to try setting it to Global mode (GSM/CDMA/LTE). The Verizon version probably wasn't tested for dual-SIM use, so it might just be the OS not knowing to switch to the other mode, or it might be an issue with the adapter itself.
Regarding an actual dual-SIM device with both SIMs being CDMA, I'm unsure if it causes any issues, as there's been no phone with that ability released yet (technically, someone can try dual Verizon SIMs in the OP3, but the CDMA implementation on that phone looks to be pretty half-assed, so I wouldn't use it as a baseline). Guess it depends on how the SIM slots are setup (if they share the same IMEI, or if they have different IMEIs for the two slots). If they're the same IMEI, I can see there potentially being issues, but if they're different (which should be the case for any modern name-brand flagship), there shouldn't be.
We'll know more once the Axon 7 releases. Unfortunately, ZTE has said that CDMA support will be coming in a software update later, but at least the phone is physically banded for CDMA, so we won't know for sure until then.

Actually the xt1644 have dual sim slots , one is hidden open the phone and you will find it

GSM potential on XT1609

So, I picked up a few of these, since my local Wal-Mart was clearing them out for $20 each. As I'm sure some of you know, the XT1609 is the Verizon Prepaid model of this phone, and as of now, when unlocked, it will only connect to LTE bands of other carriers. This means no voice through T-Mobile or AT&T, and no service in non-LTE areas.
I have a hard time believing that the hardware support for GSM is not physically present in this model. Verizon has a bit of a history of getting creative with blocking bands in their phones through software methods. Specifically, both this and this speak to me, as they were both Motorola LTE devices that gained access to their GSM radios through a relatively simple trick. (I personally owned and used both of those phones on T-Mobile.)
(Obligatory warning: DFS/Radiocomm can break stuff, please be careful. On this phone, it's labeled QCOM in the bootloader instead of BP Tools)
I tried looking around in the NV items of this phone, for 1877 (like the second link asks), but it doesn't appear that I can make changes to it with the tools available. Anyone else got any ideas?

Is possible, an Arab guy is doing it for money. The only thing we know for sure is that you will need @autoprime initroot exploit, because the Arab guy said it. Is a start

AT&T, Life Wireless, & T-Mobile (in limited capacity) have now been confirmed working on the xt1609. Voice, SMS, & 4G/LTE data fully functional on AT&T & Life Wireless. MMS & 4G/LTE are limited on T-Mobile, of course, due to Verizon implemented band restrictions.

Any more detail on that please?

Using a network other than Verizon can now happen one of two ways: (1) You pay Verizon the $70 bounty, or (2) Purchase an unlock code from a reputable service. In Settings, Mobile Networks, there will be an option to input the unlock code. The device will reboot and carrier unlocking will commence and complete upon reboot. However, keep in mind that many GSM bands have been disabled by the directives
of Verizon. I'm currently trying to enable the full spectrum of bands typically accessible on the inboard msm8916 chipset, using Qualcomm's leaked diagnostics & programming software, QPST.
