I am a little confused about some information I found on Verizon's Note 3 Page. It says that the Note 3 will be a CDMA phone but then lists the following bands:
CDMA Data – 1x and EVDO Rev0/RevA
LTE: B13 (700MHz)
Global Ready (GSM/EDGE: 850/900/1800/1900; HSPA/UMTS: 850/900/1900/2100 MHz)
(original link: http://www.verizonwireless.com/b2c/...t&action=viewPhoneDetail&selectedPhoneId=7194)
Does it mean that if sim-unlocked, it can be used internationally, and how, if it doesn't take a sim card? If it can be used internationally, I would much rather buy a Verizon (for the US) instead of AT&T. I use AT&T only because it's a GSM carrier.
I don't have the answer but I can recommend you to contact Samsung wireless. They certainly have much more credibility.
Good luck

All Verizon 4G LTE devices take SIM cards. They have to, since LTE is based on GSM. Also, historically, Verizon doesn't carrier-lock the LTE/HSPA/GSM part of their 4G LTE phones, so SIM cards from other carriers will work in a Verizon LTE phone out of the box.

I found the answer here, by the Answerer #2. The 4G/Data part of a global ready phone is GSM compatible, and only that part can be locked for data internationally; the calling part will still depend on CDMA in other countries. If that information is accurate, I will stick to an AT&T Note 3.

Truth be told. LTE has more in command with CDMA in terms of radio/air interfaces. It covered within 3GPP standards (GSM then EDGE, the UMTS, HSDPA, etc). Rather than 3GPP2 for CDMA1x and EVDO. That's why Alcatel Lucent had a leg up on LTE since its deployment is more akin (specterally) to CDMA. But they dropped the ball, and except for the US and Some Asian markets, the rest of the world has 3GPP based networks deployed.
the Simple version, is LTE is not directly compatible with any 2G/3G technology, but since its covered in 3GPP, the standards evolved quicker to ensure GSM/EDGE/HSDPA interworking.
And beyond that.. what most people dont know, that interworking doesnt really work that widespread yet. In the US most mobile handsets operate on dual frequencies (especially all VzW models, ATT models are catching up) so they effectively talk CDMA1x and LTE at the same time. iPhones do not support that capability, but GSM has work arounds to allow talk+data.
i'll go back to me hole now
(btw.. anyone with iOS7 and ATT.. what out you've got problems you dont know about when going back forth from 3G to 4G.. I know since at work we talked about how to fix it..
I believe a rumor was that it has the same LTE baseband chip as the iphone 5s so that you could potentially use the Verizon version on AT&T and T-mobile...any truth to that?

Not true, I put a T-Mobile SIM in my Verizon Note 2 and made calls, sent texts, and used data on GPRS, EDGE, and HSPA+.

Nice! Was this native to the stock Rom or is a custom one needed that has this ability "unlocked"?

Global-ready is basically verizon's way of saying that it has a GSM 3G radio as well as a CDMA radio. That allows the phone to operate in Europe where there is no CDMA service. You can purchase international service from Verizon, or purchase a SIM from a European carrier while overseas. All verizon 4G phones have a GSM 4G radio anyway, because LTE is GSM.
(This means that with an LTE carrier in Europe, any 4G Verizon phone can get data in Europe even if they can't place voice calls (VoIP still possible)).
If I am not wrong with what I am saying, Verizon LTE phones only support LTE BAND: 13, which means that IF you are willing to use 4G with different carrier, they have to support LTE band 13. I have tried to use my Verizon Galaxy Note 2 in South Korea, I was only able to use 3G network via WCDMA, I wasn't able to get LTE service at all. Correct me if I am wrong.

the different N3 variants due in fact support different LTE bands, so you are correct. Minor point not worth nitpicking from earlier post, GSM is not LTE. they both evolved from the same 3GPP standards body, but portions spread spectrum nature of LTE is more similar to CDMA than GSM.
I went to Korea last October, and they wouldn't allow prepaid 4g LTE. They would only allow 3G for prepaid service.
I had a note 2 rooted and custom rom when I went. I'm a US citizen and you have to wait about 2-3 days before you are allowed to sign up for any plan on what they told me.
Can you use a euro s7 edge in the us on sprint?
Doubtful. Sprint (and Verizon) use CDMA, and Europe has standardized on GSM for calling. I doubt the Exynos versions of the phone have CDMA radios.
While Sprint is limited on which unlocked and international phones work on its network, if you *are* able to activate it on Sprint, here's info about the limitations:
http://forum.xda-developers.com/showpost.php?p=65825260&postcount=14
Wondering if the Sprint version will work on Verizon? She has an iPhone so I know it works on Verizon and vice versa wondering if the v20 has the correct CDMA radios
Umm, try?
No, the Sprint model has ddifferent CDMA 850 MHz bands than the Verizon model.
an iPhone comes with all bands supported, so that it why they can pretty much be used on any network.
I wish LG would have done the same thing with the V20 instead of having a half dozen models.
Dammit the note 7 had all the band's on all the different carriers as well. Being that they are both 820 snaps I figured it was the same
I am on ATT network. I know TMobile phones work on ATT network. But what about Verizon,Sprint and US Cellular models? Do they work on ATT if they are sim unlocked?
it depends on phone to phone and what bands each model comes with. usually verizon/sprint models are different from AT&T and all the classic GSM carriers but nowadays some carrier has some special band while the other has control of some other band etc so you gotta do a little research when you check out a particular model to see if it'll work for your needs
Say I got a Samsung S8 from Xfinity Mobile(Verizon Network), get unlock code from XM, can I use this phone in Cricket (AT&T GSM network). Samsung support said it is ok, but from some threads it mentioned XM Samsung phone, even after unlock, some band will be locked, may not be used on other carrier. Any one tried before?

I don't see any reason why it wouldn't work just fine. The only thing I can see would be certain carrier features not working. But otherwise should be fine
Verizon and anything related to it uses CDMA technology. Whereas Cricket uses GSM.
GSM phones can be unlocked and switch carriers, whereas CDMA carriers use network-based white lists to verify their subscribers. That means you can only switch CDMA phones with your carrier’s permission.
A list of CDMA and GSM devices can be found here
Mod Edit
However, your phone might be compatible with a GSM network as cricket.
You need to check your phone's version and bands on GSMarena https://www.gsmarena.com/samsung_galaxy_s8-8161.php
And also you need to check Cricket's bands on frequency check https://www.frequencycheck.com/carriers/cricket-wireless-united-states
However, if your phone is already unlocked, you can simply insert a Cricket sim card and try to place a call and use the data to see if it works.
Thanks, understood difference between GSM & CDMA, I read other place saying all the Samsung S8 sold in US are same hardware with different firware, as long as I got unlock code from Xfinity Mobile, then I can flash phone to the new carrier specific firmware(AT&T or Cricket - which is using ATT network), can anyone confirm?

S8 has all frequencies for both GSM and CDMA. All S8s are identical hardware wise.

You are correct.
Don't think Xfinity SGS8 will work with GSM.
I believe it will only work with other carriers on CDMA like Sprint.
This is not accurate info.

At worse you have to change CSc to unlock band I have s8 Xfin unlocked and it works on att sim i know didnt look to see what bands I did see certain bands locked in hidden menu but also connected to the same locked bands on 3g

I am so glad that you replied.
So if I was to get SM-G950 US Unlocked from retailer it should work on both GSM/CDMA.

I can't guarantee it as in the past phones have been difficult to switch between Sprint and Verizon. Verizon's will work on all but Sprint based. And vice versa. But by in all theory yes all the us based models have exact hardware. And should be able to be flashed to each carrier with the csc change thread. The if anything a byop. But the best bet would be to take it once unlocked to which ever carrier and have them Install one of there active Sims and see off it works for sure.
Again shouldn't be any issues other than a few change
what's are CSs that need to be changed?
Depends on sub-model you get. If your phone is the N950U it has the following 2G bands: GSM 850 / 900 / 1800 / 1900 & 3G bands: HSDPA 850 / 900 / 1700(AWS) / 1900 / 2100 & CDMA2000 1xEV-DO. So theoretically a Galaxy Note 8 model N950U WILL work on ALL networks provided that your phone is unlocked from the carrier branded N950U. Check this webpage for the N950U specs: gsmarena.com/samsung_galaxy_note8-8505.php#n950u
If you look at the model of the phone on the back cover it will say N950U on it. N950F does not do CDMA (Verizon & Sprint), The N950FD is the same as the N950F but the "D" means dual nano sim capable (one for each girl/guy).
