Sprint version same hardware as unlocked? - HTC 10 Questions & Answers

Hi all,
I've been trying to find more information on this but surprisingly I don't think anyone has actually asked.
What I would like to know is, does the Sprint version have the same hardware to support the same LTE bands? (And 3G)
I know that this device can be unlocked to be used on a GSM network via some of the methods here on XDA, although I'm not too sure if it's going to have full network support like the unlocked one.
Thanks!

Unlocked T999 Rom/Carrier Question

I have an unlocked T-Mobile S3 and I am ready activate it on Straight Talk which I believe uses ATTs network. My question is concerning custom roms; can anyone confirm that using roms specifically for the T-Mobile version will or will not cause issues if i use a different carrier?
Thanks

I was a bit confused because there are several threads/devs trying to make sure users know to flash the right rom for their phone version. I also know that the ATT & T-Mobile versions are identical, besides the ATT version supporting ATT's LTE frequency and TM's supporting their HSPA+ frequency, and since I bought this phone off contract w/o warranty I want to make sure don't end up with a $600 paperweight.
Thanks for your confirmation!
Wait... Just some that we're on the same page, I read that as if you took a T-Mo phone, with a custom ROM, unlocked it, and used the phone on another GSM carrier, would there be problems - the answer is no.
If you take a T-Mo phone and use another carrier's ROM that's not compatible with T-Mo's phone - yes you will have problems.

Verizon Galaxy S4 Mini on US Cellular?

Is it possible to activate a Verizon Samsung Galaxy S4 Mini (or regular S4) on US Cellular's network, specifically for their pre-paid service (which is now, thankfully, allowing 4G phones)? How about the S4 international edition? I've done a lot of searching and I haven't found anything definitive, though some people have mentioned something about the LTE bands being different and therefore incompatible hardware-wise. But considering that (as far as I know) US Cellular phones can roam on Verizon's network, I'm not understanding why it wouldn't be possible. Could it be as easy as inserting a US Cellular SIM, or are the radios or other hardware different?

your best bet is to find a us cellular edition i think its the r model
verizon wont let you unless you get the unlock codes from them'
its not as simple as a sim swap with verizon devices for the most part,
phone needs to have been unlocked for it to work

I understand that the phone would need to be unlocked, but I also think that Verizon will unlock any phone that is out of contract, if I'm understanding the following correctly: http://goo.gl/vz2Jxn

Well, I'm not going to go and buy a Verizon phone in the hopes that it will work on US Cellular; that's why I posted on here for confirmation to see if anyone has been able to verify this before I actually purchase anything.
is it any different going the other way? can I port a US Cellular S4 to verizon?

Can I use the H/K Sprint M8 on T-Mobile and get LTE?

Looked around and not sure if this is even possible. Could I get a H/K M8, unlock it and use on T-Mobile's network to receive LTE? Thanks!
Is there a reason why you are looking at the Sprint version?
Its been argued whether the CDMA versions of the M8 are any different in hardware, but I haven't seen anything definitive either way. I'd err on the side of caution, assume the CDMA version is different hardware, and stay away from it. Buy any GSM version and you can convert it to work on T-Mobile (after s-off, unlocking the bootloader, etc.), no question there.

The only reason I'm looking for the Sprint version is because of the look. I like the dark back metal and gold upfront a lot. Sucks its an exclusive look only to Sprint. I read that you can flash the other non H/K models to have the same software so that is confirmed and all good.
Now I need to find someone who is using this Sprint model and can confirm it has the needed GSM radio(s) for TMO LTE.

I'm pretty sure that Sprint models are CDMA only. You can't use their phones on GSM networks. I don't think what you are trying to do will work. I may be wrong here, but I really doubt I am.

This is incorrect (that the Sprint variant does not work on GSM). Both the Verizon and Sprint variants support GSM and CDMA. Folk on here (including myself) tend to refer to them as "CDMA" for simplicity; but they are in fact also compatible with GSM, as well as HSPA, LTE.
http://www.gsmarena.com/htc_one_(m8)_cdma-6233.php
Now the question is whether the difference between the GSM and "CDMA" variants are purely in software, or there is an actual hardware difference. Its been argued both way, and I haven't seen any proof either way (although my gut tells me the latter is the case). And the question relevant to the OP is whether the T-Mobile LTE bands can be "added" to the Sprint device by software.
I used a verizon LG g2 on T-mobile a few and the phone im writing on now is a verizon iPhone full lte but i dont know aboit the sprint versions

[Q] Best way to get a phone that will work with Verizon and all LTE bands overseas

I've really enjoyed my S7 and want to upgrade to the S9. Later in the year I'll be overseas for almost a year, so I want something that will work with all Verizon bands of LTE, but also not have a firmware lock that would cause it to not work on other bands of LTE overseas. (planning to just use prepaid dataplan sim cards overseas)
I think my two options are to either get a US 'unlocked' version or wait for the 'international' version. My understanding is the primary differences between the unlocked and international version is the 2G/3G coverage for CDMA and possibly slightly different hardware. I'd rather have a phone with CDMA backwards capability, but my prime concern lacking full access to all LTE bands available wherever I am.
I'm not really interested in going any route that would require me to root the phone if there is a way to do it without.
Well the only way to get VZW compatibility is the VZW phone or a US unlocked model. So you're looking at the US Unlocked model at this point.
A listing of all the different model numbers available (per country and carrier) is available here: https://www.techwalls.com/samsung-galaxy-s9-sm-g960-g965-model-number-differences/
You will probably want to get the phone that works with your primary location the most. I am not sure which countries use which frequencies for LTE in Europe; you will need to research that to see what you may be missing out on.
With my T-Mobile S7, I haven't had any issues when traveling in Europe or Asia. It connects to LTE usually.
So I just did a deep dive of that list:
It looks like the Verizon and Unlocked versions are almost identical (the unlocked US version has B46(5200) 4G TDD LTE, but I'm not sure anyone who uses it)
Looking at 4G FDD LTE it looks like a Verizon or US unlocked phone will have almost complete coverage around the world, notable gaps are B30(2300) in China/Canada/US AT&T, B32(1500) in UK and B71(600) (US Tmobile). I thought that was a bit confusing as you'd expect a US Unlocked phone to service all LTE bands available in the US yet it lacks AT&T and Tmobile bands.
So based on all that information looks like I should just get an unlocked US phone to be totally safe, and I'd likely also be fine getting a Verizon version also.

So I'm new to Android but i use Verizon prepaid. Will I lose anything by going with the unlocked version or should i stick with a Verizon S9?
I don't use video calling. All i do is text and talk but I've heard that people on Verizon prepaid have issues with unlocked Android phones.
Thanks
Would Wifi Calling work with the US unlocked on verizon? I thought that required a Verizon FW to be flashed. I imagine all the other features such as voLTE / HD calling, etc to work on the US unlocked.

I did a cursory review of the wifi-calling FAQ on their website. They don't mention anything about compatibility with Unlocked versions of phones (that I saw). I'd call tech support to ask, but I'd expect there to be a 50% chance of getting the wrong answer from the tech based on my interactions with their support.
There might be some good experience based anecdotes in the Galaxy S8 forum, if it works on an unlocked S8 its a safe bet it will work on an unlocked S9
I think I'll ask in the Verizon subreddit, it seems like they normally have really good information as well.
I'm mostly curious about the LTE TDD Band 46 (5200) - its the only band an unlocked US phone has that a Verizon phone doesn't. 5200 is in the U-NII frequency range, no cellphone service providers use it, but I wonder if it may be used for local LTE networks in the near future. The other advantage is avoiding all the verizon bloat wear, but that may be what allows the Wifi Calling to work!
All this has me thinking I might have to add the extra $80 and just buy the Verizon version. I don't get phones on contract and I've always just paid full price. (Page 2 404 error?)
Apparently the Nov/Dec Samsung s8 firmware update added an option for BYOD carrier provisioning for unlocked s8. Given the similarity, I'd imagine the same to be true for s9. Can someone who has an unlocked s8 confirm?
Well after a little more research I see that if you use Verizon prepaid you lose visual voicemail and WiFi calling even if you use a Verizon phone so there's no need in me paying extra for a Verizon S9. Unlocked it is.

You might wanna check this as Verizon is starting to implement network locks on some devices as to deter thefts more
Dont know when or what devices but it was a statement Verizon made
So, you're saying the prepaid SIM might not work in an unlocked S9?
I don't think Verizon is keeping Verizon prepaid SIMS from working in unlocked phones they are just locking their phones like Sprint and AT&T still do.
I had no problems with my unlocked Pixel 2 XL that I purchased from Google and my Verizon prepaid, just no visual voicemail.

AT&T S9 Root unlock question

Hi,
If I take a AT&T S9, Unlock the bootloader (if possible), root it, and flash a custom rom on it will I then be able to use it on Verizon?
Thank you in Advance.

ATz&T is GSM Verizon is CDMA incompatible
Perhaps @sw1173 is a dinosaur or a forum troll?
Verizon 4G LTE is not CDMA. It's 4G LTE and fully compatible with 4G LTE used by other carriers around the globe. Verizon 2g and 3g is CDMA, and only still exists to support older cellular data and IoT devices and some dinosaurs using ancients relics for devices. Verizon announced they were planning on completely shutting down their CDMA network the end of 2019, but just recently decided to postpone the shutdown for up to another year. Verizon has been permitting activation of an ever expanding list of unlocked phones for some time now, including devices like the OnePlus 6T that has no CDMA support, just 4G LTE. If you already have a 4G LTE device activated, you can swap the SIM into another 4G LTE device and as long as it has radio band support for Verizon's spectrum (use frequencycheck.com) as well as software support for Verizon's VoLTE settings, you're good to go. They don't seem to have a VoLTE whitelist like AT&T.
Sadly, the bootloader on the US Snapdragon S9 can not be unlocked at this point (no hacks) like the foreign SM-G960F(D)/965F(D) (Exynos with unlocked bootloader) or the SM-G9600/9650 (Snapdragon with unlocked bootloader) in order to install custom ROMs. I suggest everyone avoid US Samsung phones, period, because of this, and be sure to share your discontent with Samsung. Personally, if I were you, I would get the SM-G9600 or SM-G9650 (China / Latin America Version), root it (easy), and flash the files here to get Verizon support:
https://forum.xda-developers.com/galaxy-s9/how-to/guide-sm-g9600-sm-g9650-verizon-t3890695
If you buy or have a carrier unlocked US S9, including from AT&T, you can use it with any US carrier, including Verizon. You'll probably want to flash the Verizon firmware on it to get Verizon features including WiFi calling though:
https://www.reddit.com/r/GalaxyS9/comments/85ci7c/convert_atttmosprint_to_unlocked_s9_guide/
Presently you can't unlock the boot loader on the n960u therefore you can't flash Verizon's firmware. Call Verizon and you will be told they are CDMA and are not changing but are adding capability for 5G after 1/1/2020, which will allow the use of various GSM devices to use their CDMA network.. I just spoke with Verizon sales and their technical support.

incorrect, this has been incorrect since the S8 when Sammy decided to not make different models for the US market. All S9's built for the US market are physically identical

in addition to this correct information, id like to add that phones can be debranded by flashing the U1 firmware, but will require a modded Odin in order to get around the write protections put in place meant to stop us from doing that

incorrect. Well, youre right in saying that it cant currently be unlocked or rooted, but you CAN flash verizons firmware. Verizon hasnt been a cdma carrier strictly speaking for a decade. LTE has always been GSM, and ever since vzw jumped on board, theyve been a hybrid at best. On top of that, with VoLTE becoming more and more popular, their cdma transceivers have been getting less and less usage every day. 5G isnt going to be the splash a lot of folks think it will either. New handsets to support a new communication method that just isnt needed in most places. And finally, most handsets produced in the last few years are hybrids, especially those sold in several countries. The biggest exception to that rule is the chinese phones that dont even have cdma radios in them.
