Does SM-G950 / SM-G950U1 (US Unlocked) support TDD LTE Band 40 (2300MHz)? - Samsung Galaxy S8 Questions and Answers

I bought an SM-G950U1 (US Unlocked) from Best Buy. Does any one know if it supports TDD LTE Band 40 (2300 MHz)?
There is conflicting information on this! Answers given in various specs vary as follows:
YES (it supports LTE Band 40) --- according to specs given by sellers like Best Buy, B&H, and many online sites like gsmarena, phonearena, frequencycheck.com, etc.
NO (does not support LTE Band 40) --- according to the Samsung support person I talked to over the phone. Also, the FCC filings for SM-G950U do not list TDD LTE Band 40 (they have only one TDD band listed, Band 41, presumably for Sprint). On the other hand, although TDD LTE Band 41 is actually known to work with the SM-G950U1, the official Samsung SM-G950U webpage does not list any TDD band at all, not even Band 41 (it lists only FDD LTE bands).

Does anyone know the real answer here? Has anyone actually tested the SM-G950U1 for Band 40 support in a suitable country (Peru, South Africa, India, Australia)?

I don't have a carrier that would have Band 40, but here is the thread which lists all bands for different versions of S8. You can try asking there as well.

Thanks. I have posted to the thread you mentioned. It is surprisingly hard to find the answer to such a simple question for such a flagship device!

Band 40 LTE is there. Open phone and dial *#2263# and it will list all bands active in the phone, including 40. It is in mine.

Thanks Danny Noman! The *#2263# code did work and showed Band 40. Wonderful!
One question: The *#*#4636#*#* info menu does not seem to work on the S8 (works on many other android phones). Any idea what might be an equivalent for the S8?

N7100 or N7105

I really have no idea but it appears the N7105 is international version with no LTE, at least that works with ATT. The N7100 is the model number with LTE that will work with ATT. Is this true? Negri Electronics is selling the N7100, the spec says "4G Network LTE 700 MHz Class 17 / 2100". Does this work with ATT 4G LTE? Is this the model, if you want LTE, to buy?
I preordered from Negri a week ago, but definitely want LTE in U.S.so keep order or cancel? Many websites reference in specs LTE but others call for 2 models....anyone really know. Clove U.K. simply calls device Samsung Note 2, no reference to N7100 or N7105. It clearly doesn't show in specs 4G LTE, only 3G.Handtec (U.K.) calls out phone N7100 with the following spec:"3G: HSPA+ 21Mbps (HSDPA 21Mbps / HSUPA 5.76Mbps) 4G LTE: 100Mbps/ 50Mbps (HDSPA 42Mbps / HSUPA 5.76Mbps)
So which is it? Does anyone know?
I am not sure, but in the fcc documents for the N7105 there's no mention of lte at all.
So I believe that the n7105 is the international without lte.

If you live in the US, you want LTE. It's awesome in every respect. It's like having a FIOS line in the palm of your hand.
In Singapore, Note 1's model number is GT-N7000 while Note 1 LTE is GT-N7005. I do believe that Samsung's naming format for their international handsets doesn't differ from country to country. Therefore GT-N7105 is Note II LTE. just my educated guess.

There are at least 5 different versions if not more. Although it is LTE capable, the version sold for England does not have a LTE chip, The German one does but it will not work on ATT. There are no LTE networks in Europe that I know about compatible with ATT LTE bands. If you buy one in Europe plan on using 3G and 2G on ATT. Make sure it has these bands:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 1900 / 2100
ATT uses 850 and 1900 for 2G and 3G. You need both.
To use ATT LTE you need a chip for this:
LTE 700 MHz Class 17 / 1700 / 2100.
From what I can tell, even if you happen to buy out of country versions that are compatible for some LTE frequencies for example AT&T, it may not be as compatible as phones you would get from AT&T directly because of the mix and match LTE spectrums that AT&T and all other carriers have purchased. I'm guessing the days of importing International versions are over if you care about good LTE coverage.

N7105 is LTE for LTE2600 (B7) and LTE800 (B20). Those frequencies have choosen for LTE in France
I wonder if the Korean LTE one released today will work in uk when our 4g is up and running. Anyone know?

Unfortunately not. I believe that South Korean LTE is on 1800MHz. Post auction UK LTE frequencies are 800MHz and 2600MHz (these are the bands to be auctioned off before the end of 2012). However, it will likely work on EE's Interim LTE network.
Everything Everywhere will launch an 'interim 4G' solution, running LTE on some of its unused 1800MHz spectrum (from the T-Mobile/Orange Merger). This will be rolled out to 16 cities before the end of the year. EE 4G is up and running as we speak, but only for dongles, and one cannot yet buy a phone on contract from them.
Aside from that, O2 and Vodafone have lots of spectrum at 900MHz, depending on what they secure at 800MHz, they might ask ofcom to allow them to run LTE on 900MHz, likely siting ofcoms agreement to allow EE to run LTE on 1800MHz as ammunition!
Three (which only had 2100MHz spectrum since its a 3G only provider), has bought some 1800MHz spectrum off EE. They have not yet declared what they will use this for, but one would suspect limited 'interim 4G' like EE.
There are basically no phones out there at the moment that support both post-auction UK LTE frequencies (800MHz and 2600MHz). France apparently uses 800MHz and 2600MHz although only the latter is currently live. There is a note 2 variant on its way that does 800/2600MHz. Lots more will follow.
The problem we have in the UK, is that we might end up with 4 LTE bands: 800MHz, 900MHz, 1800MHz and 2600MHz !!! No phones are going to be doing all this lot anytime soon. (I was wrong: Nokia Lumnia 920 does, Samsungs do not yet)
Additionally, what happens post-auction to EE's (and perhaps 3's) LTE network at 1800MHz - are they just going to shut it down (one would assume not!) If not then future phones for that network will need to do 800,1800 and 2600MHz. Will they cover the initial 16 cities with 800/2600MHz as well as 1800MHz to keep the early adopters happy?
UK LTE is a mess. Its partially DSO (TV digital switchover) that's to blame, but ofcom could have sold off the 2600MHz spectrum some time ago, and then done the 800MHz auctions after DSO. This is the way that France chose to run its auctions. If ofcom had done this then we could have had 4G 12-18 months ago, and we could not have ended up with half-way-house 1800MHz LTE from the likes of EE.
Anyway to answer your question, if you get any of EE's current phones: iPhone5, SGS3, Lumnia 920, (and, if they announce it, Note 2 - Korean) etc then these ONLY do 1800MHz LTE EE's 'Interim LTE' (and perhaps 700 and 2100MHz LTE - which are useless in UK). Early next year, EE will start to spread coverage outwith those initial 16 cities, but they will do this using the 800MHz and 2600MHz LTE they won at auction.
That phone you got from them wont work on these post-auction LTE frequencies. You'll likely be on a two year contract, paying dearly for the fact that you adopted LTE early since those that waited would enjoy much better LTE coverage from their later-generation phones. On top of that, your phone, not having the right radio's for UK LTE will be worth sweet FA on ebay!
The operator arguments over the 800 and 2600MHz bands have hardly started yet. If O2/Voda get permission to run LTE on their 900MHz spectrum (and are also allowed to bit on 800MHz), you can bet you house that the operators without 900MHz aint gonna be happy!
What really gets me regarding all the arguments, is that neither O2, vodafone nor (to a lesser extent) orange ever bothered to implement 3G properly. It works in cities, thats about it. Only Three and T-Mobile actually implemented a reasonable 3G network that covered most of the UK.
Personally, I would forget about LTE for 18 months until there is a viable network, and some viable hardware that is actually able to take advantage of all the LTE infrastructure no matter what frequency is happens to run on! I certainly would not be signing up with EE (or three if they do 1800MHz LTE) for 2 years, just to be the first - as there's good potential to get caught out 9-12 months down the line.
For the operators, there are other issues at 800MHz. Folk living close to base stations are likely to loose the freeview muxes that are sat in the low 800MHz. In simple cases, this is fixed by a filter, in other cases, it will require a new roof antenna, while for some other folks, it will require a switch from freeview-freesat. One of the conditions attached to the 800MHz spectrum is that the mobile operator needs to fix-up the TV signal's for any customer that is likely to be effected. This will also reduce the radiation patterns, and thus range of the base stations in certain directions. Ofcom will only allow switch-on of the BS once the MO has fixed up all potential TV reception issues. Its going to cost them a fortune!
NB: What what I have seen thus far, Galaxy S3 and Note 2 don't do 1800,800 & 2600 in the same device. BUT Nokia Lumnia 920 does.

Reading the following suggests that the Korean version (N7105?) supports all three networks - SKT, KT and LG U+:
http://sammyhub.com/2012/09/26/samsung-announces-galaxy-note-ii-for-south-korea/
... and, according to the following article, the only frequency supported by KT is 1800Mhz:
http://www.macrumors.com/2012/08/15...e-for-8001800-mhz-lte-service-on-next-iphone/
This would suggest that the Note 2 for Korea supports 800, 1800 & 2600Mhz.
Korean versions:
SK's SHV-E250S Supports Band 3 and 5
KT's SHV-E250K Supports Band 3 and 8
LG's SHV-E250U Supports Band 1 and 5
So basically if I'm on ATT here in the states with my Note 1, I should cool my jets and wait for the official US ATT version comes out instead of jumping the gun and getting an international version. Am I correct?
This GT-N7105 sold on NegriElectronics details these LTE bands:
Code:
4G Network LTE 700 MHz Class 17 / 2100
Unfortunately, I think Negri Electronics is misinformed over the specs of the N7105. Although they list the necessary LTE bands for AT&T, I believe that may be incorrect. According to Android Authority and the FCC, the N7105 does not support USA/Canada LTE bands sadly... I hope we're all proven wrong soon though!
Alternatively, assuming all other features and hardware of the AT&T/Rogers Note II are exactly the same as the international N7105, then it's likely possible that we can simply flash N7105 firmware out of the box, but continue to use the modem.bin from the carrier firmware for continued LTE functionality. That's what I did with my OG AT&T branded Galaxy Tab, and it worked brilliantly!
So, to recap:
1. Int'l N7105 is likely NOT North American LTE friendly :'(
2. North American carrier branded GSM/LTE Note 2's will likely have 99.9% identical hardware to Int'l N7105 (the .1% difference being the tweaked LTE radio and modem.bin driver file)
3. Possible workaround for North American users would be to get GSM carrier Note 2, retain modem.bin from carrier firmware, flash Int'l N7105 firmware, flash carrier modem.bin, and viola! North American LTE friendly Int'l Note 2!
Hmmm, I may have to contact them for clarification and cancel my order if that's the case.
Will update when I get feedback from them.
Edit: Talked with a Negri CS rep, and he suggested I cancel my pre-order and wait until they receive units to verify compatibility. That's what I have just done.
Engadget have a review up with the lte bands and model numbers. BUT
they don't list the 7105 as having band 1800 which is EEs network yet EE are set to sell the lte variant next week. :-/

EE's LTE Variant
T-Mobile UK called me yesterday to confirm that they've received stock of the Note 2 LTE. I received a text to confirm that one of these is scheduled for delivery to my home within the next four hours (by midday UK time). Once it arrives, hopefully I can tell you exactly which bands in addition to band 3 (if any) are supported.

LTE TDD on SM-G900F

Is there any possibility to unlock a TDD LTE band (B38 2600MHz TDD) on the international/european version of Galaxy S5, which officialy supports only FDD (as any other Samsung device sold in Europe)? The chipset is the same with the TDD version of S5 (SM-G9008V) sold in China, so it's just a firmware limitation. I've read this thread but nobody confirmed the functionality of any TDD band.
On my G900FD I have set the two NV items to only band B38 and it seems not to work. Even the Service app (*#0011#) shows an empty list for the supported LTE bands. I also tried setting all bands, quite a few additional bands were shown but the app doesn't seem to be good enough to display a longer list of LTE bands so no idea where it ended. It is possible that for this model the stock firmware does not even bother to check whether the TDD bands are enabled. I also tried to connect to B38 from CM12.1 latest nightly but B38 was not found and I have not found yet a method to read the supported LTE bands from CM.
LE: I tried and only added B38 to the stock 1/2/3/5/7/8/20 and B38 didn't show up in the service menu.
Seem their no develop working on band enables.

Pro 3 x727 - UMTS B4 (1700/2100 AWS 1) Frequency?

I'm eyeing this phone to replace my well worn S5. Does anyone know for sure if the x727 variant has the UMTS B4 1700/2100Mhz? The listings on the various Chinese sites are hit and miss, that's why I'm looking for first hand info. Based on my research the x720 appears to have 3G band 4, but it is unclear if the x727 does.
Thanks!
x727 is the NA version, which launched alongside the US version of Le Eco's online store. It supports B2/4/12 and VoLTE + WiFi calling on T-Mobile.
I'm planning to use it on Freedom Mobile in Canada on their 3G network (not LTE), that's why AWS band 4 on 3G is a requirement.
Thanks.

T-Mobile US also relies on 1700/2100 AWS B4 for HSPA/UMTS. LTE discovery shows the LTE band, so I'm not sure how to do the same for HSPA.
I found the FCC application for the x727 and the SAR exposure report lists WCDMA band 4 @ 1700Mhz, so I'm good to go. Coincidentally it appears the device has the highest radiation level on that band.

How do I REALLY add or change LTE bands on my xiaomi redmi 3s?

i have been trying to change the lte bands on my phone for the longest now. i have been following a bunch of tutorials on how to do it but none of them ether hinder nor help mu issue, no matter what i try i dont unlock anymore bands or delete any. i have even tried putting nonsense in the NV section and it dosent remove my current bnads which lead me to believe that for xiaomi phones theirs additional or alternate steps to unlock more bands. has anyone done it before? i need to unlock T-mobile LTE bands
2 (1900 MHz), Band 4 (1700/2100 MHz), Band 12 (700 MHz)
because my company lycamobile is under tmobile

Lol, pardon me for misreading the OP
This guide published here should be useful.
It’s not an easy process and there is rooting required, but it will take you through and work for you. You will also need to have your phone rooted before doing it.
All in all, it’s a complex and scary process, and if you’re not used to meddling in your smartphone’s innards, I would recommend staying away from it.
You might end up bricking your phone and losing it altogether.
Also, depending on why you are doing it, some applications of this solution are illegal and might get you in trouble with your carrier.
So just be careful
One more, according to this site, our phone did not even support those frequency which he wanted to work on his phone.

N9860 - Unlocking LTE band 17 in Canada?

I'm thinking about getting an N9860 since it seems to be the cheapest Snapdragon option for a Note 20 Ultra.
This phone appears to support all the necessary bands for my carrier (Koodo) in Canada except LTE band 17. I live in a big city so this low-ish frequency band will be important for reception in areas with building density.
I've seen discussions around changing the CSC to potentially unlock additional bands, but I'm having trouble understanding whether that means all Snapdragon models support the same bands.
Could anyone provide clarification about this? Has anyone managed to unlock band 17 on this HK/CN model?
AFAIK, you can not unlock bands. I'm in Canada too but with Fido and Korean N986N. No band 17, but the reception has been fine so far aside from VOLTE and wifi calling not working.
