So, I'm currently in a debate with a friend over the announcement of the LTE on Verizon. My friend (who works in multiplexing telecommunications) tells me that all current Verizon phones will receive a firmware update in order to move onto the LTE network since the current EVDO RevA communication is similar to that of LTE.
I completely disagree and state that the current radio functions on all phones including the droid incredible cannot handle communication with the LTE standard and will require a different chip in order to properly access LTE network.
Does anyone have any documents or citing that says current 3G phones are not forward compatible with LTE?
Thanks.
It would take David Copperfield to make LTE work on our devices
You might want to convince your friend to place a large bet on this with you because there is virtually no way that I know of that he will win the bet. Your friend has lost his marbles...

LTE requires a SIM card, which will never be delivered Ota, nor inserted into ur Dinc. Tell genius to stick to multiplexing, and if he doesn't listen take his money.

I agree, place a very large bet on this. You are absolutely correct. I work for Vzw, if I didn't run the risk of getting fired for screenshotting some of the documentation we have about 4G, I'd attach it. 4G devices will be backward compatible with 3G networking, not vice versa.
something but what
LTE no, but voice&data at once maybe?
I was on the phone with VZW activating a new device last week and the rep on the phone was trying to tell me that certain devices will end up getting an update that allows for data communications and voice communications simultaneously. Which is currently not possible. I tried to tell them that this sounded like it was not possible and that only new devices with new hardware will be able to do such things. They remained firm that certain current devices would get an update to allow this. I just don't see it happening. Time will tell.

I have a Galaxy nexus with Verizon with cm 11, I was wondering if I can take it to tracfone. I called customer service and they told me I can buy a activation code and a sim card and it will work. But I was wondering since I have a custom rom would it work. And if it does can I flash toro roms?

As far as I know verizon does not allow 4G device on tracfone/net10/straight-talk BYOP plans. I would loved to be proved wrong.
I don't think ROM is an issue, but I've read that people had difficult with the initial activation until they flash back to (unroot) stock, activate and then reroot/install custom ROM.
YMMV. Do let us know how it turns out!
I will definitely let you guys know, my contract with Verizon will expire in a few days, I'm so tried of paying so much money for cell phone service. If this doesn't work I will buy a nexus 5 and take it too T-Mobile.

I tried this - it doesn't work.
a big NO?!?
Well I have been fighting with tracfone for about a month now and only had them erase my account once so not as bad as some times.
I have tried most every permutation as well and am currently trying factory mysid/toro 4.2.2 (JDQ39) with locked bootloader and all I get are busy signals on activation. Tracfone finally says my phone and my LTE sim card are good. Tracfone also says things are ok on their end. Everything looks like it should work, yet no.
Has anyone else EVER gotten a Samsung Galaxy Nexus SCH-I515 to work on tracfone?
Moving a GNex toro from VZW to Tracfone - all done!

Actually, you ARE wrong; I'm taking my own ex-VZW GNex to Tracfone, and it does NOT have to be stock when you do it.
Tracfone itself is a neutral (CDMA/GSM) MVNO and uses the towers of three providers (T-Mobile, Sprint, and VZW) on a regional basis; the difficulty is that it's easier to port a Tracfone phone number - which you can't do from a feature phone. This is why you need a customized SIM kit (pre-loaded with the target phone's IMEI and MEID). I'm taking a lifeline number issued by Safelink Wireless (Tracfone's lifeline brand - porting such a number is legit), and the IMEI and MEID are hardware-specific - NOT carrier-specific (the IMEI and MEID travel with the phone - and are neither carrier-specific or ROM-specific; other than the stock ROM, I have changed firmware twice, and neither IMEI or MEID changed a whit).
What you have to do is go online and explain the situation to the agent (that you are transferring your existing number to a former VZW Galaxy Nexus); the agent will ask for the IMEI and MEID of the target phone, and confirm that said phone is NOT active on VZW's network. The bigger issue with the SOURCE phone is that - more often than not, it either uses a different SIM (Tracfone sells LTE phones itself; however, they also sell feature phones up to 3G, such as various Alcatel models that don't run Android) or doesn't use a SIM at all (these non-Android Alcatel OneTouch models are in that category). As a backup, grab Tracfone's Transfer Wizard from the Play Store after the ROM changeover (it's a free app).
SIMs for phones are of three sorts - standard (the oldest Android phones, such as our GNex), micro (later, but not necessarily current, such as the Nexus 5 or 6) or nano (Nexus 5X, Nexus 6P, and Pixel, Pixel XL, and Galaxy J3) - the SIM must match the phone! I have a nano SIM for Google Fi - can't use that in a GNex; microSIMs are commonly purchasable, even for Tracfone - however, I can't use THOSE in a GNex, either. Hence I have to go custom. (Turns out I was wrong; the GNex uses a microSIM - I took a picture of it after the swap (the VZW microSIM, that is). When I have enough points, I'll attach the picture I took; it's currently backed up to cloud storage.)
When your SIM kit arrives, you WILL need the number from the source phone - with feature phones (including lifeline phones, such as the Alcatels I mentioned), this will be in the Prepaid section of the phone's menu. There will almost certainly be a "dummy" SIM in the phone you are moving; that is fine; as the Galaxy Nexus does NOT support SD cards at all, that tell you where your new SIM should go.
While you wait
Like a lot of the phones of the same age, the Galaxy Nexus can be used as a tablet while not on anybody's network; further, unlike most tablets, it supports both 2.4 GHz and 5 GHz. This lets you "explore" a bit and find the ideal ROM for you and your apps - not all ROMs , even for the GNex, are the same; between straightforward OS variety and other ROM-specific features, the differences are legion. (Not every user will be comfortable with Unlegacy Android - or even with 7.1, for example.)
My SIM Kit arrived, and it is FULLY compatible with most CDMA (and all LTE) phones from VZW. Even according to the booklets (plural - both English and Spanish), stock firmware is not a requirement. (In fact, I'm doing this with OmniROM 6.0 Security Update installed.). The surprise is that the GNex uses a microSIM (not a standard SIM) - I'll be including a picture of it in a later edit (the original one from VZW). The transfer is, in fact, nearly done; the hiccups were all on the back end - and had mostly to do with a quirk in OmniROM 6.x; the animation of the logo went a bit screwball (it kept not only repeating itself, but interfered with app recognition). It's why I put Unlegacy-Android back on the GNex in question.
If you have issues
This is actually included if the number ports, but hangs between Tracfone and the phone itself (and is referred to via the documentation) - auto-programming mode; you dial (via the Phone Dialer included with GApps) a special number (it doesn't even look like a real phone number, so you can't dial it by accident) and the phone is programmed to your new carrier (Tracfone, in this case) utterly hands-free. (It's also why even if you are running a non-stock ROM (all too likely), it's utterly irrelevant.
Lifeline phones
Yes; lifeline numbers from Safelink CAN be ported this way - in fact, Safelink is specifically covered as a number source - so you do NOT need to purchase an airtime card (either now or for at least a year - my ported number is, in fact, covered until January 2018). Be warned, though; your feature phone will basically become a paperweight.

Decidedly yes - any ROM you could flash before the move, you can flash AFTER the move; it's still toro-based.
Carrier choice
The very reason I chose Tracfone is that they are neutral - they use multiple carriers (in this area, it is either T-Mobile or VZW) to provide service. The very reason, in fact, I have tried to avoid T-Mobile is due to my ALWAYS having signal-strngth issues with T-Mobile towers (and not just with Safelink; Virgin Mobile USA also uses T-Mobile towers with THEIR feature phones). However, unfortunately, you DO pay a premium in this area to use VZW compared to a neutral MVNO - and you can't get lifeline service directly from VZW (at least here).
ROM choice
ROM choice is NOT carrier-dependent - unless your phone is carrier-locked - which is not, and has never, been true with Tracfone (unless you are talking about feature phones; however, that is, in fact, true of all feature phones, regardless of carrier). You can choose any community ROM that your phone supports - and Tracfone won't care. (My issue with OmniROM has more to do with an animation issue in OmniROM itself - an issue that UA doesn't have - which is why I put UA back on the phone.) Also, I took a good HARD look at the Tracfone TOS - which in no way blocks community ROMs - not even on Android phones sold by Tracfone itself - let alone BYOP. (Also, do you realize that Tracfone sells a LOT of Android phones? Tracfone is, in fact, the largest carrier in terms of HSN phone sales, and trails only VZW on Amazon (and not by much, either). If anything, just in terms of TOS, Tracfone is the most friendly carrier in terms of community ROMs - also, how many US-based carriers even HAVE a real BYOP policy? That you can also port lifeline numbers (the number I ported was a lifeline number) drove the point home with a jackhammer.
The Bigger Issue
The biggest issue I have EVER had with Tracfone is that they tend to rely on T-Mobile towers compared to VZW for feature phones (at least locally) and compared to using feature phones on VZW (which I have done as a former VZW prepaid customer) quite frankly bites - especially in the exurbs. I haven't gone urban with the phone itself since I moved the number; however, I will before Christmas; we will see if the service improves. (Voice service - not data; since I won't be using cellular data at all; why would I when I have access to Comcast's network of hotspots at a cost of none?)

I have taken several i515 and a Maguro to Tracfone with many different ROMs ...Tracfone uses Verizon Towers for activation...the only thing Tracfone needs is the MEI number to activate not what ROM you're using...Not Verizon is a different story...sometimes they want you back on stock ROM to activate...some people just like to cause trouble...LOL

VZW is that way because they do in-store/dealer activation; Tracfone does not. Further, Tracfone allows for DIY (automated) activation; sensible, since they also allow for BYOD - again, this is something that VZW does NOT do. I don't hate VZW (or even Verizon as a company); in point of fact, in most cases, I recommend VZW for prepaid and NEW hardware because of the strength of their network and towers (compared to anyone else - especially T-Mobile). VZW's lowest-common-denominator is the salespeople in the stores and dealer network (like used-vehicle salespersons); Tracfone doesn't have any of that to deal with. If you're familiar with community ROMs, I can recommend Tracfone and especially if VZW has towers in your vicinity (because - unless T-Mobile has an exclusivity deal in your area - which is darn unlikely - you will be on VZW's towers for LTE); quite frankly, VZW beats T-Mobile with Da Ugly Stik for LTE or CDMA (somewhat understandable, as T-M is still a GSM network at heart - ex-VZW LTE gear - and especially phones - prefers CDMA for voice, as VoLTE isn't out yet). Before I walked into the world of Android, I had been using exclusively feature phones (with VZW, Virgin Mobile, and later Tracfone/Safelink). That gave me the opportunity to evaluate all the carrier networks for connectivity with as little money risk as possible. VZW won there with Sprint a surprising second.
I see some people saying they already turned on their VoLTE, how does one go about doing this? I'm on the latest Kernel, running the latest PacMan ROM.

you need to return to stock in order to get the volte. when you try to restore via KIES it will ask you if you want to upgrade to the ne6 baseband. click on yes and be patient
So we can't use custom roms to get volte? We have to stick to stock rom?

Volte will not and does not work at all if you are using Pacman rom
or any other AOSP, AOKP, CM or ported roms.
You will need to flash a Samsung N900T Kitkat 4.4.2 Touchwiz stock or
stock based custom rom if you want to get the Volte feature working.
Good luck.
yea i tried flashing all the different options/roms trying to figure it out. only the stock telco rom works for volte. thanks

I have been searching for custom ROMs that can do VoLITE and i think I found one called XtreStoLite but I do not think it will work yet on your device. Someone told me something about wrong kernals, and until they make it install from a universal zip it is not workable yet.
But I would keep an eye out on that one and I think they are going to soon come up with more custom roms with volte.

T-Mobile Unofficially Speaks To Us About Band 12 LTE / VoLTE And Unlocked Smartphones,
And Yep It's Still Confusing
-----------------------------------
Yesterday, we published an article asking an open question: what is up with T-Mobile band 12 support being removed from some unlocked smartphones?
Today, T-Mobile contacted us to speak about said article. Unfortunately, T-Mobile was unwilling to provide any official on-record responses to our questions. But after a short discussion, I can provide you some information I have learned on background (journalist speak for "cannot be directly quoted or attributed to anyone"). First:
On T-Mobile, any device on its network with band 12 LTE data support must also support T-Mobile Voice over LTE services and E911.
The E911 part isn't particularly important in terms of the certification requirement - all phones sold in America are technically E911 compliant, because by law they have to be. The problem is that E911 compliance is inextricably linked to T-Mobile's VoLTE requirement for band 12. Without VoLTE support, a device on band 12 service would be unable to make phone calls of any kind if no other T-Mobile band was available (it will not know to fall back to AT&T roaming - the call will just flat-out fail), and that would include making 911 calls, meaning the device would for legal purposes likely be out of E911 compliance, and T-Mobile could get in trouble with the FCC. Not to mention, you could have somebody trying and failing to dial 911 in an emergency, which would of course be terrible. And yes, by removing band 12 support, you can make E911 work, because the phone then has no signal at all and knows to try to roam onto another compatible network (AT&T usually) to complete the call. This is both a safety and liability issue, and it is easy to understand where T-Mobile would be coming from in terms of concern about this - they do have something of a history with E911 debacles. Clearly this is a very real safety concern, and I do sympathize with T-Mobile in the sense that they obviously can't just sit here and do nothing about it. But there are practical concerns for OEMs here - adding T-Mobile VoLTE isn't just as easy as flipping a switch.
In order to obtain VoLTE compliance for band 12, phones must go through T-Mobile's rigorous network certification process (and yes, unlocked phones can go through this certification).
Speaking off the record to one major smartphone vendor, we have learned that there are very real costs and complexities associated with obtaining that certification, and it must be done on a device-by-device basis. Many phone OEMs, then, may simply choose to remove band 12 support from their unlocked smartphones sold in America. This could mean phones like the Alcatel OneTouch Idol 3 (4.7 and 5.5), the Huawei Ascend P8 Lite, the Huawei SnapTo, OnePlus 2, Moto X Style (aka Moto X 2015 PE), Moto X Play, HTC One M9 Unlocked and Developer Edition, Saygus V2, and various imported phones (ie, some global unlocked Sony or Samsung devices) or unlocked branded AT&T phone models may lose band 12 support in future software updates. The fact is, we don't know what will happen, or to which phones, or when. Some manufacturers may choose to get T-Mobile VoLTE certification (Motorola has hinted as much with the new Moto X 2015 PE), but many may also simply choose to quietly disable band 12 for T-Mobile in software updates. Motorola, as we know, has already done this with the Moto E.
It is not clear what action, if any, T-Mobile will take if a smartphone vendor refuses to remove band 12 data support from their device and also refuses to undergo the T-Mobile VoLTE certification process. (Ie, they want to keep B12 data but not bother with B12 VoLTE certification.)
This is basically the kicker. What will T-Mobile do if a vendor says "no way" to dropping band 12 data, but also doesn't want to go through the VoLTE certification process? We don't know. They might not do anything. But they might do something. Again, this is why speaking to T-Mobile about this situation was so frustrating. Not only we were unable to directly quote or attribute any of the information we were provided, but there was also no clarity as to what would happen in the event the band 12 situation comes to a head with an OEM that refuses to "play ball."
It seems unlikely that any OEM would refuse T-Mobile's request here, though, as most of them are also partnered with the company on T-Mobile-branded devices.
We have asked T-Mobile again for an on-record statement about this entire situation, because it would help clarify it immensely. As things stand now, T-Mobile is attempting to put the ball in the court of manufacturers. Which, to be fair, manufacturers do have a role to play here - they have to make the decision to drop band 12 or go through the T-Mobile certs for these unlocked band 12 devices. Or, potentially, just ignore T-Mobile's band 12 requirements entirely and see what happens. Unfortunately, as you might guess, most smartphone OEMs have zero desire to discuss upcoming software updates in detail, or to ever put their product in a situation where it is being highlighted for losing a feature. That makes our job here a difficult one.
We will update you on any more information we receive about this situation, including any response from T-Mobile or potentially-affected device manufacturers we have reached out to.

hey there, im using galaxy note 3 t-mobile running on AOKP rom android 7.1.2 with synergy kernel, the problem is when i switch my network to LTE from GSM, my device getting freezed and unresponsive after 3-4 minutes, this occured in Resurrection Remix and Linage OS, can anyone help me fixing this problem? and i dont want to go back to stock rom, thanks in advance
I have an unlocked Sprint Samsung S6 and I'm trying to get it to work on Verizon but it doesn't want to work. It shows an exclamation and R where the signal bars are. I have tried setting up the APN and a Verizon rep put the sprint phone in their system, but that didn't work either. Is there any way to get this to work? Do u have to flash Verizon's Rom to it? I noticed that even unlocked it still seems to have the sprint activation stuff..... Please help, scoured the Internet and forums to no avail :/
If you actually got the phone activated onto your line on Verizon, you will need the Verizon PRL on the device for it to show it connected natively to its towers (the 'R' is a roaming indicator...your device is seeing the Verizon towers as roaming since it loaded with a tower list with Sprint towers prioritized). Verizon is still CDMA, so you will need the proper PRL flashed to the phone for it to work, first & foremost, along with your NAM information and all of the Verizon data settings flashed in place of the Sprint data settings. With regard to CDMA switching from Sprint/Sprint-based to Verizon/Verizon-based, there is more to it than merely an ESN swap (activation by an agent) & inserting a SIM.
I am not here to hold your hand through the flashing of anything, but I'm letting you know what will need to be done. These phones have different model numbers for a reason (unlike "hybrids" like newer Nexus devices, newer iPhones & the recently released Moto X Pure). These different models are designated per carrier and the bundled carrier software for many CDMA devices is used in its OTA programming. Sprint devices typically are packed with MSL/SPCs unique to the device and needed to edit the internal NAM & data settings while Verizon branded counterparts have 0s instead of uniques codes. If this is all over your head, you may need to seek the assistance of someone or a company familiar with flashing to get you going if you are hellbent on using THAT device. Good luck.
worked for me but not stable
I also have the s note 5 from sprint and been trying to make it work on verizon. After so many tries in the mobile network setting i got it to partially work. it still have the R symbols on top, which shows your roaming but you will get a 3g speed. My current setting is
Settings>Mobile Networks>Network mode >automatic
Settings>Mobile Networks>data roaming>Roaming network>automatic
Settings>Mobile Networks>data roaming>Roaming guard> all off
Settings>Mobile Networks>data roaming>everything else on
you also have to use the verizon app settings.
i've also tried flashing the prl but had no luck. Any suggestion on how will be appreciated.
So, how about an idiot's guide for making this happen?
If I need help from a vendor, how about posting some referrals, what needs to be done, and how much is fair to pay?
I am a self-professed newb and I just want to take the Sprint S6 that I own outright to Verizon.
Especially because I paid full price for the S6, and Sprint's service sucks inside my building.
Thanks .
What VicFreeze said above is 100% correct, you would have to reprogram/flash the phones CDMA chip/radio and even Verizon will not be able to do so (legally or maybe not smart enough to know how), you want to be on Verizon you need to get one of their phones. Your phone is a G920P, the P is specific to Sprint and the phone has been flashed internally to know the MIED, MDM/MIN, PRL and login passwords for their networks along with the MSL Code direct from the Samsung factory just for Sprint.
So Yeah you can change all this by reprogramming the CDMA chip inside the phone, first you need professional software that will cost $$$ hundreds of dollars, software like CDMA workshop, QPST or DFS will work, learning to use this software is not for newbies, you will also need to get the information from Verizon to flash their carrier specific codes and numbers into the phone, it's not like swapping out your SIM Card like a GSM Phone and your on a different network, this is CDMA and its why Sprint/Verizon use this, its to lock you down. (no, that's not why)(LOL)
Just Google "Carrier programming on CDMA phones"..
I think it would be cheaper to sell your Sprint phone and just get a Verizon phone and save yourself a lot of hassle. Get a G920V, its already flashed with Verizon Codes to access their LTE Network from the Samsung factory (Hence the V is specific for Verizon). Verizon's sales staff might not even know what a CDMA phone is so would you really want them to reprogram it??

VicFreeze and MindTricks sound dead on in there advice. One thing I am pretty sure about unless someone corrects me is .... even though Sprint and Verizon are both CDMA, they operate on different frequency bands which is probably why your getting the 'R' for roaming. CDMA Workshop has the ability to change the radio frequency. I think the two companies also encrypt or code their voice and data traffic and you need the software flashed that has their specific decoders or encryption software for the device to work on their system. I am not sure if the specific radio software changes any of this or not. I am not even sure is CDMA Workshop is compatible with newer Samsung phones now as two years ago I programmed my Sprint HTC EVO 4g to work on my Virgin Mobile talk and text plan without much trouble but have not been able to get CDMA Workshop to connect to a Galaxy Grand Prime as of late. What I did two years ago was easier since Virgin runs off of Sprint Service Towers. Having a ROM compiled for Verizon may help but things have changed. What I did with the EVO two years ago ..... the ROM had Sprint radio files compiled with it. I am not sure if some of those files are separated in the system now on more modern devices as ..... back two years ago Sprint was EVDO and not their LTE uses a SIM card to work. So, things have changed and keep changing and evolving. One thing is sure, is almost every year Service Providers along with device manufacturers are changing what they do and how they do it.

That's what everyone would love to do but at times proves more hassle than what it is worth. this is why there are sites like Swappa and eBay where you can sell your phone for close to competitive price and pick one up a device that is a comparable condition for the service provider you want to swich to for about a break even price or not much more out of pocket.
I dunno if this thread is dead but process should go something like this.... flash factory binary firmware checking "auto-reboot, nand erase, and F.reset" options. Once it boots enable developer options and oem unlock and usb debugging (then do a factory reset from settings menu). Then you can flash the CSC from Verizon stock. Placing VZW .pit file in appropriate section. Then you can flash the BL,AP,CP files from VZW rom. Personally....this seems like alot of unnecessary work with a great chance for missing something. Might be better to root sprint device and manually install vzw modem files, apns.conf, prl, telephony.db.....better yet why not just flash a custom rom from twrp. thats just one zip file in twrp.
I don't know what I've done differently, but I currently have and use without any problems a Sprint G920P on the nations most reliable network… Verizon. I can tell you that I didn't have to jump through all or any of the hoops that others in this post have outlined. I will tell you what I did ; Flashed G920p with Bigdaddy PL3 Aroma V1.x ,TWRP-3.2.1.0, SuperSu-v2.82, and 3.10.61_Stock_Modified_Kernel_By_Aurora_Rom [email protected]#1. Phone has been unlocked by Idonne apps. I believe that last bit has a lot to do with my success. there is a setting in his app if the phone is to be used on a CDMA network or a GSM network. And not to discredit the person that discouraged you from having a Verizon employee help you but it was he that figured out how to make Verizons system find my phone. Not sure exactly what he did but I saw him take his company phone out of his pocket and scan the sticker on the back of it into the system saying "we will just make the system recognize it". Voila, worked perfectly and continues to operate without flaw on their network. I do get a roam "R", but checking settings indicates that I am not roaming. I live on the border to Canada so it is to be expected, but not the case. As far as Network, device says Preferred Network instead of Verizon. It could say your name for all I care as long as it works! Hope this sheds some light on it for you without having to make all of those unnecessary changes. One last note.... the salesman did say that mine is the first Sprint Device that he has seen on their network.... I guess that makes me special huh? Lol...
Hi all,
I have in my hands an unopened G960F/DS. I was considering this phone to replace an old model, it's long due. I thought I did my homework and was able to determine this phone worked on Verizon in the US, but a serious note on the box and further research suggests I may have been wrong. Although it would be nice to have new hardware, I am replacing the old one almost entirely out of a desire to flash a custom ROM on it. I was under the impression the lack of CDMA support wasn't a big issue given that Verizon (and everyone else) is phasing out CDMA and the phone still had LTE. Thus my choice of the F/DS. I am informed that opening the box and returning the phone will incur a charge, while keeping the box sealed and returning it will not. I am trying to decide to continue forward and test on Verizon's network here in the US or just return the thing, the choice lies in compatibility with this network. So now I get to play a guessing game.
I find myself in 4G LTE areas most of the time. I want to use data and make voice calls.
This 2-post thread suggests not much can be done:

This guy demonstrating slower speeds, which I'm not too concerned about, but also HSPA+ in an area he usually gets LTE. In the video description he says after applying a software update it works 'fine':

This site lists some band compatibility but doesn't say anything about not being able to use it with Verizon:

This site also lists band compatibility but warns about Verizon's strict device policy:

Is there any hope to use an unlocked S9 on Verizon in the US? I see this going one of several ways: 1) Everyone works out and I can make calls and use data and there are no issues and rainbows and unicorns 2) Data in certain places, no voice because something something "VoLTE" 3) Absolutely no data/voice whatsoever 4) I switch carriers I return this piece of junk and buy a phone that works. (might coincide with 2/3)
If I end up with (4), how can I avoid this issue in the future? I spent some considerable time deciding on this model, which has the features I want and an unlockable bootloader. Will the S10 have this issue? What about the Note 9? I apologize for the noobposting, and if I missed a thread that answered this question. Thanks for any help you can provide, I sincerely appreciate it.
Edit: This thread asks a similar question but isn't specific and neither are the answers:

I have been using a G965f/ds on Verizon Wireless.
VoLTE, vowifi, text, and data work after rooting.
Having done a speed test with a U device and on the g965f/ds, the speed I can receive seems equal.
I haven't had issues with making LTE calls in my area.

Thanks for the feedback. Are you based in the US? How did you activate the phone? I found instructions on LTE activation here:
www . verizonwireless . com/businessportals/support/how_to_use/activate_4g_lte.html
And an IMEI checker, which fails when I enter what I find on the box my phone is in:
www . verizonwireless . com/od/prepaid/bring-your-own-device/#/checkDevice
Edit: It also looks like they have a second page that checks IMEI (this also fails for me). Can you tell me what either of these pages say when you enter your IMEI?
www . verizonwireless . com/onedp/byod#/
I reside in the US.
The imei of my g965d/fs failed when inputted in to their system;however, the SIM is all that's needed for Verizon wireless to work on it. Initially, though, you might need to insert the SIM card into another imei Verizon wireless compatible device only to allow the system to have that imei in the system for your number. Since, you already have vzw, I'm assuming you already are activated on it with a device, so moving sims is the next step.
Thanks for your input. Anyone else have experience with this device on Verizon's network?
I could have written this exact post.

I am trying to do the same thing with the same model Note 9, SM-N960F/DS. I was told by Verizon Level 2 tech rep that simply installing an activated SIM would make the phone work, obviously 4gLTE only since there are no CDMA bands. He checked the 4 bands Verizon uses for their 4gLTE and the F/DS model has all 4 of them.
I am in the same boat as you though. IF I try it and it doesn't work I have to return and lose $125 or switch to GSM network (AT&T or TMO) I am also trying to decide whether to take the gamble. This Level 2 Tech guy didn't mention anything about having to root the phone.
I would also like to know about the advisability of attempting this. I thought I read somewhere that this phone won't have any warranty in US anyway but I am not 100% sure about that. Sellers seem to want to gloss over that issue.
I'm very very interested in this
to put this to bed, you cant use any F galaxy phone on verizon and get full usage. vzw is a CDMA based carrier whereby voice is transmitted primarily via CDMA and data over GSM (which includes voLTE, obviously). The F model do not have CDMA radios in them. You CAN get data to work and therefore voLTE as long as you can flash the vzw CSC to get the phone to install the voLTE app. Long story short, dont try it. Its a fruitless endeavor. I mean, do what you want, i guess, but dont expect for the F to work well, or at all on vzw. There is nothing anybody on xda or anywhere can do to alleviate that.
I had straight talk using Verizon towers on note 8, my note 8 broke, I missed flashing custom ROMs, I bought a note 9 n960f, read online it would work too. I inserted sim. Did not get data or calls. Flashed custom ROMs found a lineage is rom that worked with data for like 2 min then quit. I kept Singapore rom csc stock radios I guess from Singapore, guy on here said he flashed Singapore stock Odin flash and ended up making his work but didn't work with my straight talk Verizon sim. My buddy came over and he uses visible network on Verizon towers we popped in his sim and it worked flawlessly on stock Singapore csc/flashed custom rom from xda. I switched, it's cheaper, it works and first month was 5$ no fee to transfer my number over. Visible is great, join a group and it's 25$ a month.
