[Q] Which note 3 for these connections

I need a note 3 that can:
connect to AT&T LTE here in the USA
And connect to T-Mobile NL in Holland
And unlocked bootloader
ATT:
850 MHz CLR 5 UMTS/HSPA+ 21Mbit/s 4G In service
1900 MHz PCS 2 UMTS/HSPA+ 21Mbit/s 4G In service
700 MHz Block B 17 LTE 4G In service Main LTE band providing complete coverage
1700/2100 MHz AWS 4 LTE 4G In service Additional LTE band for more bandwidth in select markets
1900 MHz PCS 2 LTE 4G Service starts by the end of 2013 Additional LTE band for more bandwidth in select markets[31]
2300 MHz WCS 30 LTE 4G Approved for deployment in Oct 2012[32]

TMO:
This company uses GSM1800 as their main frequency band for communications. In 2010 T-Mobile Netherlands had some problems with 3G capacity, but after investing in the network modernization they have managed to deal with this problem. So now they provide 3G services using 2100MHz band

Am I restricted to the N900-T? or is there another one you know of.
sorry for the noob question i don't know about all the bands.
Thanks!

T-Mo NL uses the 900Mhz for 2G, 2100Mhz band for 3G, and are in the process of updating to the 900Mhz band for both 2G and 3G. (Should be finished by the end of 2016.) LTE runs on the 1800Mhz band. (I can dream these numbers by now...)
You can find the bands per phone version here: http://forum.xda-developers.com/showthread.php?t=2574886
Does the TMo US version even work with AT&T?
Both N900-t and N9005 work in terms of frequency for 2G.
You will probably not be able to use the N900T for 3G once the network upgrade is finished here, as we're going to be using the 900Mhz as the main frequency for 3G. The N900T can't see that one. The 2100Mhz will be serving as a bandwidth increaser, not as the main band.
There's a chance you won't get 4G everywhere on the N9005 when using it in the US, as it can't see the 700/1700/1900/2300Mhz frequency.
And you're going to have to root to get rid of the region lock either way if you want to use both SIMs.

Tmo version 4G will not work with AT&T 4G. I tried with my wife's phone

T-Mobile (US) devices support the same frequencies as AT&T devices. This is coming from experience and from the fact that I've pretty much memorized all the band numbers that carriers use and phones support.
If you want a Note 3 that supports AT&T LTE in the US and HSPA+ in NL, you can either get the AT&T model or the T-Mobile model. The T-Mobile model supports one extra band (1700 MHz HSPA+) that is only used on T-Mobile US (nowhere outside of North America), so it wouldn't make a difference. Just know that it CAN be used on AT&T. The other differences between the two:
1. The T-Mobile version supports Wifi Calling (if used on T-Mobile), AT&T model doesn't.
2. AT&T removes the "Network Mode" menu from the Settings menu (so you can't force EDGE for example).
3. AT&T version has a locked bootloader. T-Mobile version doesn't.
In many instances, although 900 MHz WCDMA/HSPA+ isn't listed, it's supported. I can't confirm it because I'm in the US, and GSM carriers use (total) 850/1700/1900/2100 MHz for WCDMA, not 900 MHz. I think it's just unlisted to discourage people from exporting the US models. The only LTE frequency that North America shares in common with Europe is 2600 MHz, which is supported by the phone. I believe that's only used in urban areas in Europe.
Overall the T-Mobile model is the most open in terms of bootloader and supported frequencies (though either model would work in your case).

[Q] S5 international models & LTE band support?

hello all-
has XDA (or any other site) released a hardware list for the regional S5 models with the differences in hardware and especially LTE band support?
It's pretty frustrating in 2014 that Samsung *still* appears to be forcing regional divisions on its customers; especially when the Nexus 5 has already proven that support for many different regional frequency bands can be included in a single device.
There's no reason for it whatsoever except to inflict artificial restrictions on where customers can buy, and where they can use a phone. If I buy a phone outright I expect to be able to use it anywhere. If I travel, why should my original carrier dictate who I can get coverage from?

Try to get the S5 Google Play edition. Google Play edition smartphones and tablets are carrier unlocked and unbranded. Instead of having a massive Verizon 4G LTE logo, or a phone that only works on AT&T bands, buying from the Play Store you’ll receive a completely untethered smartphone. The Galaxy S4 Google edition works on AT&T, T-Mobile, and around the world. There’s no contract required, and you can use it on a variety of carriers in the US, and abroad. So, I think, the S5 will work the same or better.

That sounds reasonable and logical, but is that really the case? What were the hardware specs of the S4 GP edition? Wasn't it just an unbranded SGH-1337- which then has no LTE support on T-Mobile or anywhere outside North America?
What I'm looking for is a device that is universal around the world, or around the country (US/Canada/Europe/Asia). I want a phone that (like the the N5) for example won't be kneecapped to HSPA or vanilla GSM when I travel to Europe, Japan, China or Hong Kong; or if I switch carriers within Canada. The N5 claims to support over half a dozen LTE bands, ensuring it can find one supported in essentially every region. Samsung still appears to be trying to artificially partition markets by radio and other features, much like many electronics manufacturers do with artificial trade barriers like region-encoding on DVDs, Blu-Rays or video games.

You should really read the specs of the phone before posting wrong information.
S4 GE won't support LTE abroad. LTE will only work on AT&T and T-mobile.
S5 GE is not yet even announced.

There is no such phone.
N5 of North American edition doesn't work on LTE in Europe. Neither N5 of European edition works on LTE in the US.
NA and EU LTE bands are different.

Ugh
I'm not going to get any carrier renewal benefit, so I'm just going to have to pay full freight for this phone. So since I'm paying full price, I might as well get the best phone. I want a 32GB version (have the 32gb s4), that does LTE in NA. I'd rather not get an AT&T phone (locked bootloader crap that has forced me to get repairs on my own dime on my phone so I don't get a locked version from the mothership).
Sounds like the GP version is best, then I can slap it on At&T network, any other ideas? The Rogers S4s seems to have so many issues with ROM upgrades and such... So painful!

if i buy the 900f, european version, will i get LTE data in canada on the Rogers network? i believe rogers uses the same bands as At&T...
i been seeing different things posted on the internet which has me very confused....
it seems like the supported LTE bands are similar between the european version and the at&t version..with the exception of two bands...
any expert can chime in on this please? thanks..

It would have been better if you started a new thread.
To answer your question, the 900F shares most of the LTE bands that Rogers uses. So assuming that your 900F is provisioned for Rogers LTE.. yes you will get Rogers LTE data. The 900F does not support Rogers LTE bands B4/17 (or 3G B4), but they are not much used yet, so you shouldn't incur any gaps in coverage.
In the future you may miss B17 more as it is new and uncongested spectrum that just rolled out in Vancouver, Calgary and Toronto. And being a low frequency is particularly good at penetrating into buildings. But for the moment, you'll be good.

My G9008W work perfectly in France with LTE with band 1800 and 2600
But it seem that it has no B20 (800Mhz), but i am not sure ...
It work also in 3G (900 and 2100) and 2G, of course
Just ont think: unlike the Galaxy S4 Duo, it is not dual active, only one sim in communication at a time ...

Mobile Network Bands and Oneplus One

I hope the following information is applicable for all countries....
India's mobile frequencies & bands are
2G : GSM 900 MHz, GSM 1800 MHz
3G : WCDMA/HSPA/UMTS 2100 MHz ---- which are equivalent to BAND 1
4G : TD-LTE 2300 MHz ---- which are equivalent to BAND 40
As you all know only Airtel is providing 4G in india in TD-LTE 2300 MHz.
Two types of LTE -- FDD LTE , TDD LTE (NEW China Standard mainly)
TD-LTE -- Time-division Long-Term Evolution
LTE TDD -- LTE Time-Division Duplex
TDD LTE -- Time-Division Duplex LTE
All above 3 are same I guess...
And the main stream LTE is called FDD-LTE - Frequency-Division Duplex LTE
-------------------------------------------------------------------
OPO International Bands are ----
-------------------------------------------------------------------
2G: GSM: 850, 900, 1800, 1900MHz
3G: WCDMA: Bands: 1/2/4/5/8
-- Which are equivalent to --- 2100 /1900 / 1700 / 850 / 900 MHz ( Frequencies)
4G: LTE: Bands: 1/3/4/7/17/38/40
-- Which are equivalent to --- FDD 2100/ FDD 1800/ FDD 1700/ FDD 2600 / FDD 700 b c / TDD 2600 / TDD 2300
OPO Chinese Bands are ----
-------------------------------------------------------------------
2G: GSM 850 / 900 / 1800 / 1900 MHz
3G: WCDMA: 2100 / 1900 / 850 / 900 MHz
TD-SCDMA：1880-1920/2010-2025MHz
-- Which are equivalent to --- 1/2/5/8/39/34
4G: FDD-LTE :2100/1800/2600 MHz
TD-LTE：1880-1920/2300-2400/2570-2620MHz
-- Which are equivalent to --- 1/3/7/39/40/38
-------------------------------------------------------------------
So for India Both versions should work with all available telecom providers.
Let me know your thoughts guys...
:good:

No 4G on OPO in India
I thought of buying one, but seeing that it uses FDD LTE instead of TD, 4G will not work on this device in India.

WIND Mobile in Canada uses AWS Bands 1700/2100 in Canada. This phone is compatible with 4G 2100 as it shows, but not 1700. Do you think I will have 4G connectivity? Or 3G?

I bought one one from Lenteen and the 4G works perfectly in France with SFR

Does anyone know if flashing CM11S onto China OnePlus Ones will unlock the international bands? The CM11S factory image has a radio image. CM11 builds also include a radio.
Asking because I'm not receiving LTE signal on my China OPO that I've flashed to CM. Then again I have yet to try my SIM on another LTE enabled device...

Well, yes and no. I brought back 3 Chinese OPO from Beijing, and flashed the first via fastboot while transiting in Tokyo - that one would NOT work in any of the Japanese carriers (using two different SIM - Fido from Canada and TuneTalk from Malaysia) while Samsung Galaxy S3 worked fine. The second one I flashed once back in Canada via the standard recovery method as described by GizChina, and that one does not work on AWS band when tested with Wind Mobile SIM while Fido & Speakout SIMs worked awesome
Given my Japanese experience I'm not inclined to think the fastboot flash is any better than standard recovery flash

[Q] Is it possible to flash different radios to gain GSM?

I've been at a loss on what to do with my Note 3 since moving to St. Louis. I was at first under the assumption that since it has a sim card slot it could be unlocked and used on GSM carriers and boy was I wrong. The USCC variant does not support GSM at all, and only operates on CDMA. I'm not accurate in my assumption but I assume that the US Note 3s all contain the same hardware but different radios flashed to the chipset preventing access to North American GSM. And now the challenge:
With Root and recovery access is it possible to flash a radio from a GSM variant and match the kernel and then subsequently a GSM Rom to turn the USCC into a GSM capable device?
To start I have found the following infoModes

Buying the SM-N910W8 need help to understand some things...

I'm going to buy the Samsung Galaxy Note 4 SM-N910W8 from amazon.com, I seen that's the canadian version. The buyer says that's compatible with all GSMs worldwide, not only in North America. As I'm from Argentina, and the bands in Argentina are GSM-850 and 1900 MHz, does it work here? Also, the 4G LTE is coming to my country by the end of next year, with 1700/2100 Mhz and 700 Mhz bands for it. Does it work here?
GSM Arena says that the SM-N910W8 is compatible with:
3G- HSDPA 850 / 1700 / 1900 / 2100 - N910W8
4G LTE- LTE 700 / 850 / 900 / 1700 / 1800 / 1900 / 2100 / 2600 (Bands 1, 2, 3, 4, 5, 7, 8, 12, 17) - N910W8
As I don't know about this (never seen the compatible bands when I buy a phone as it's the first time I buy one from USA), I don't understand if that means that's compatible or not.
Other question: What SoC does it have? Snapdragon 805 or Exynos? If it's Snapdragon, does it means that's compatible with Roms of other models?
Help please! Thanks!

If you can live with (potentially) reduced lte coverage then no reason you shouldn't go for it.
If you want to ensure maximum coverage then you should really find out what 700mhz band is to be used in your country (band 17 or 28).

Acording to Wikipedia 700MHz band 28

Which version of Samsung Note 4 phone is a better buy? SM-N910A vs SM-N910W8 [Moved
Hello,
I'm trying to make sense of the LTE frequencies, so maybe you can help.
The situation: I'd like to buy the phone and use it on AT&T LTE in the US, but -- very important -- also use it for data when traveling outside the US. Also, I'd like the ability switch providers in the US (that's why I'm not buying a subsidized phone from AT&T).
The question: The Note 4 model SM-N910W8 has more LTE frequencies than the model SM-N910A. I assume it means that the SM-N910W8 is more likely to perform well in foreign countries and on other US carriers. If so, that's a better purchase than AT&T model of the phone (SM-N910A). Is this correct?
The data:
According to GSM Arena, the "North American" model SM-N910W8 supports
LTE 700 / 850 / 900 / 1700 / 1800 / 1900 / 2100 / 2600 (Bands 1, 2, 3, 4, 5, 7, 8, 12, 17)
According to Samsung website, the specialized AT&T version of the phone SM-N910A supports
2G GSM : 850/900/1800/1900;
3G WCDMA : Band I/Band II/Band V;
4G (LTE Cat 4 150/50Mbps) : B2 / B4 / B5 / B12 / B17
(the system won't allow me to provide links to the data sources, but PM me if you'd like them)

Thanks to everyone, I just decided to buy the N910C version due to I'm sure that it will work in my country (as it's the model that will come here officially). "Preparing for Shipping" says Amazon, I cannot wait!
