Hey everyone,
Are the 3g versions going to be CDMA with Verizon meaning no SIM card? I purchased the NYC wi-fi only tab and will be tethering, but a friend was curious about the 3g option. I said that i think it will be with verizon and will not have a sim, but wasn't 100% sure. I remember that the I/O ones came with free Verizon LTE for a short period of time which led me to my conclusion. Could someone please clarify for me? Thanks for the help! Excuse me if I am way off here...haha.
The only one officially ANNOUNCED so far is from Verizon w/CDMA, no SIM card.
If the Verizon edition has 4G LTE it'll have a SIM card slot (LTE requires a SIM).
What about the 3G bands used by the device? I have not been able to find any specific details about them ):
One would assume that the Verizon edition will support their normal bands (800/850Mhz & 1900Mhz and if LTE 700Mhz).
As far as I know, Verizon is using the N900V on their network which requires CDMA band.
I bought a SM-N900W8 from Telus Canada and after having it unlocked, I was unable to have it registered under my Verizon account.
So, not wanting to pay the outragious roaming price that we have from our greedy Canadian Carriers, I purchased an AT&T Pay as you GO sim card.
TaDa!!!!
This is due to the use by Verizon of CDMA band which isn't supported by most Canadian Cellphone that requires at least WCDMA OR LTE/GSM Band.
So, if you're planning to travel the USA and are looking to get an American SIM Card, most likely, verizon will not be an option for you (they're expensive anyway)
AT & T and T - mobile supports the GSM as far as I know.

I currently have the AT&T variant of the galaxy s5 and I would like to get replacement that I can root, I know that most all variants are compatible on the gsm side but I would only want one that would be compatible with LTE on AT&T of course as well. Could someone please let me know the variants that would work on the LTE network for AT&T please. Thanks in advance!!

I suggest T-Mobile's variant, which is what I use on AT&T's LTE network with no problems.
Can you use an unlocked T-Mobile S7 on Sprint? I'm not sure if it has all the bands (CDMA & LTE) to be compatible. Would you need to flash Sprint firmware or is it simply not doable.
not possible cause it doens't have CDMA internals. CDMA phones on the other hand can, cause they have both CDMA and GSM internals.

Figured but was hoping that wasn't true. Thank you.
all of the snapdragon s7's are the same internally.. you just need to flash g930u to it
Well, because it is unlocked, you CAN use it on Sprint, BUT you can only use it on LTE. Because it doesn't use CDMA, you won't have 3G and below. This is problematic in spots where you don't get LTE because you will instantly drop to no signal.
What about an AT&T S7 Edge? Would it work on Sprint? Model # SM-N935A?
All of the US S7 variants are exactly the same hardware-wise, meaning they all support CDMA.
You could flash the U firmware on it but you won't be able to activate it on Sprint becuase it is neither an original Sprint or an original U variant unit and hence isn't in their white list of allowed devices on their network.
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

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.

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).
