Hi all, I'm a long time user on XDA but I think this is my first new thread, so be nice
I'm keen to build up a list of LTE bands supported by the various variants of the S4. Current specs online seem to be fairly sketchy on what LTE bands are going to be supported by our pre-order phones. The general consensus from most sites is that the overall network frequencies supported will be:
GSM/GPRS/EDGE 850/900/1800/1900MHz
HSPA+ 850/900/1900/2100MHz
LTE Cat3 Up to 6 different band sets (dependent on market)

I'm pretty much set on getting myself an S4 however unsure on what I'm actually buying into at the moment. I'm UK based (on o2 currently) but travel to the US several times a year. I've had the HTC Sensation XE which supports 1700MHz and therefore allows me HSPA connection on T-Mobile USA, and their $3/day prepaid tariff is brilliant. Going forward AT&T is also a possibility but their tariffs are a bit steeper (seem to need to pay for a month at a time).
So... what I'd like to do is pull together a list of supported bands for phones sold in various markets/regions/countries, as we get more detail on LTE bands supported. If folks are happy to post links to detail/evidence then I will compile this into a list. Would prefer to stick to the E-UTRA Operating Band numbers as opposed to frequencies.
For my own situation specifically, I'd also be keen to understand:
- Bandings of those phones sold by Carphone Warehouse UK, o2 UK, EE, AT&T, T-Mobile US
- There's a list of LTE bands on the S4 page on Wikipedia (so a big pinch of salt required): 700, 800, 1700, 1800, 1900, 2600 MHz. Is this likely to be the base European offering? If so, what band numbers would these correspond to, since a lot of the frequencies are used by several bands?
- AT&T apparently uses 700MHz for LTE - is that nationwide or just certain states picked up through acquisition of smaller carriers?
- Is T-Mobile US likely to get a special variant to support HSPA at 1700MHz?
- How widely has T-Mobile US reapportioned HSPA at 1900MHz (from the old MPC)
- If a new handset is bought outright at AT&T or T-Mobile USA, will they provide an unlock code free of charge?

From what i know, there are three market variants of the Galaxy S4.
GT-I9505 – Snapdragon 600 1.9 GHz with LTE - US and Most Western Markets
GT-I9500 – Exynos 5 Octa 1.6 GHz without LTE - Asia and Reast of the World Markets
SHV-E300S – Exynos 5 Octa 1.8 GHz with LTE - Korean Markets

Thanks for the list - I think there's a semantic issue here though which reflects much more widely than this particular forum. For me this is about markets (e.g. countries, retailers and carriers) and in each these markets, what LTE bands will be accessible if I buy a i9505 handset. Will all of Europe and North America get the same LTE access? My impression was no. We could go quite granular with this...
UK:
Carphone Warehouse - i9505 with LTE band a, b, c, d, e, f
EE - i9505 with LTE band a, b, c, d, e, f
o2 - i9505 with LTE band a, b, c, d, e, f
Three - i9505 with LTE band a, b, c, d, e, f
Vodafone - i9505 with LTE band a, b, c, d, e, f
USA:
AT&T - i9505 with LTE band a, b, c, d, e, f
T-Mobile - i9505 with LTE band a, b, c, d, e, f
Verizon - i9505 with LTE band a, b, c, d, e, f
Sprint - i9505 with LTE band a, b, c, d, e, f
etc etc...
In a country like the UK it could be the case that all of the retailers and networks all support the same bands... but I just don't know for now. For the US that probably won't be the case.
Potentially we could build up a picture for all countries?

I've been waiting to find out more information about this as well.
I'm in Canada on the Roger's network, and when I visit the US, I too use the T-Mobile $3 a day plan.
Unlike the S3, does this mean that all North American S4 variants will be the same phone (Telus, Rogers, Wind, T-Mobile, Verizon, etc)? If so, does that mean that if I purchase any S4 in North America that it will work on all North American cell networks?
Thanks!

Pleased to hear I'm not the only one looking for this detail. It seems to odd to me that something's going on sale in just over a week but we aren't informed of exactly what it is. If Carphone Warehouse would confirm their model includes LTE on bands 3, 4, 7 and 20, I'd pre-order a sim-free phone right now
I'm hoping to find out what are the frequencies 9500 support, not 9505.
Because 9505 has already been revealed.
If, within US, the bandwidths are carrier-dependent, what about international 9500?
I live in the US and I'm also very interested in LTE band info amongst the different variants. I have the Verizon GS4 [SCH-I545] on preorder and currently using the AT&T Galaxy Note [SGH-I717]. I know absolutely nothing about UK carriers or their LTE bands etc, but know a pretty good bit about the US so I'll layout some of the info I have so far. Also I travel to Japan a lot so I would be interested in their LTE info as well.
Firstly, the GT-I9505 is not a variant that is intended for the North American market. (We are special and Samsung always makes us special ones ) It can probably be bought online in the US, but no carrier is selling that model and I wouldn't expect it to be compatible with any LTE in the US (though it could work).
LTE Bands US carriers use that I know of:
AT&T (Evidence)
Currently Used Bands: 4, 17
(Band 17 is the only one I've actually seen when I look at my phone and I believe is used in all their LTE markets nationwide so far)
Future Use: WCS Band [EUTRA unnumbered ~2300Mhz]
(Evidence)
Potential Future Use: 2, 5
(See SGH-I337 supported bands for evidence)
Verizon (Evidence)
Currently Used Bands: 13
Future Use: 4
(Verizon to begin rolling out band 4 Summer 2013)
T-Mobile (Evidence)
Currently Used Bands: 4
LTE Bands of North American GS4 Varients:
AT&T SGH-I337
Bands: 1, 2, 4, 5, 7, 17
(Samsung Website Shows Bands 1,4,7,17 and FCC License Testing shows Bands 2,4,5,17 [Bands 1, 7 are not used in the US, therefore FCC doesn't care to test them.])
I think Samsung made a typo on their site listing all the bands because FCC documents proves that this phone can operate LTE on band 2 and 5.
Verizon SCH-I545
Bands: 4, 13
(Evidence and Evidence)
T-Mobile SGH-M919
Bands: 1, 2, 4, 5, 7, 17
(Evidence and Evidence)
Sprint SPH-L720
Bands: 25
(Evidence and Evidence)
LTE Bands on International Variant:
GT-I9505
Bands: 1, 3, 5, 7, 8, 20
(This is my best guess based on the this info. However, 800 and 850 could be any combination of bands 5,6,18,19,20,26,27. Also 1800 could be either band 3 or 9. Some of these are subsets of others.)
(Also, this proves that it at least has LTE band 5.)
I can post more info as I come across it, but hopefully this will get you started.
do you know if the s4 is the same everywhere for frequencies and then limited via software or it actually has different hardware? I'm referring to the s4's in the USA vs the international version.

Would this international version with Bands: 1, 3, 5, 7, 8, 20. work on Rogers highest speed LTE Band 7?? EVEN though this phone is unable to connect to rogers LTE band 4???
Answers to this question will be thanked!
All of the major japanese LTE carriers (not counting emobile who is a minor player) operate their primary network on band 1.
Softbank bands 1/18 (and band 41 TD-LTE)
Docomo bands 1/19/21 (band 3 to come)
au bands 1/11/18
Emobile band 3
Docomo is the only carrier with the S4 (phones are bought locked, subsided via a carrier shop 99.9% of the time in Japan). The japanese variant (SC-04E) only interoperates on band 1. The radio claims band 4 support but I was never able to make it operate with T-mobile LTE.

Many of the versions of the S4 have different hardware, but for the ones that do have the same hardware (all the US versions), it's hard to tell whether the frequencies are set through software or hardware. I imagine the only way to verify would be to, for example, try an AT&T modem on a Verizon phone and see if it can connect to AT&T LTE band 17. If not, then either there are deeper incompatibilities between the two phones, or the hardware is not able to receive that band.

I am inclined to say yes, except that via Samsung's website it has a disclaimer stating that the bands it supports depends on the market. Which I interpret as meaning that the supported bands depend on where you buy the phone. So perhaps if you bought the phone in a market where band 7 is utilized, it would likely work. (Assuming it's unlocked.)

According to Samsung's spec page on the SC-04E The phone only supports "800,1500,2100MHz" which I assume are bands 1, 19, 21 as the phone was intended for operation on Docomo which uses all 3 of those bands on their network.
If you are referring to the service mode menu when you say "the radio claims band 4 support" I have found that to be an incorrect for all of samsung's phones lately. For example, my Verizon Galaxy S4 service mode menu claims it supports bands 2,3,4,5,7,8,17,20 which is completely false as Verizon operates only on band 13 at this moment and this phone absolutely doesn't support AT&T's band 17.

Not entirely sure I understand this post, but I'll try to respond anyways. From what I can tell, the platinum-band in Japan refers to any bands in the 700-900Mhz range? So for Docomo, that would be their 800MHz band 19 allocation, which according to this map, they have almost no coverage with that band (the orange parts of the map) unless you live in the Chūgoku region. Their map does not distinguish between band 1 and band 21 but, based on an article I read here, it is safe to say that there won't be significant deployments of band 21 until after March 2014, and that even then they will only be in "key metropolitan areas" according to the article.
All that is to say, that I think it's clear that the vast majority of Docomo's LTE network is deployed with band 1, so therefore it makes sense that you have only seen that band being utilized on your phone. As for the mountains, again refer to the map, they don't have much of any LTE coverage in the mountains so it makes sense that you are limited to UMTS there.
Thanks guys for this detailed info, it does bring some hope for me to use my S4 bought in the UK in the USA while I travel for a week.
So just to confirm, a Vodafone UK phone would work in T-Mobile USA network on 4G speeds?
Also, I want to know more on the Three-UK's "Feel at Home" offer - did anyone use their S4 in the USA and how was your experience with this?
you UK version will only work with T-Mobile 1900Mhz 21Mbit 3g where they use it (very few places) It won't work on 4g lte.
Bear pricing in mind. I was in the US for 5 days a few weeks back but on three. I used their new free USA roaming. Between 1 and 2 GB hspa+ and all included. Worked great on s4 i9505

thanks very much for confirming! happy days :angel:
Just wanted to give some info I found using QPST(qualcomm software) to see what cell bands are configured for our HTC One M8. I even looked at the Rezound bands as well. As most of you know, verizon didn't carrier lock our phones, so if we switch to global or even GSM network, we can use other carriers GSM SIM cards. Just need to properly configure the APN's of course. Below are the bands that the phone will search for when Global Network is selected. I pulled this configuration from my actual device. The Rezound only was missing Bit 19 & 49 selection, but everything else was selected:
[Bit_00] Band Class 0, A-System
[Bit_01] Band Class 0, B-System
[Bit_02] Band Class 1, all blocks
[Bit_07] GSM DCS 1800 band
[Bit_08] GSM Extended GSM (E-GSM) band
[Bit_09] GSM Primary GSM (P-GSM) band
[Bit_19] GSM 850 band
[Bit_21] GSM PCS 1900 band
[Bit_22] WCDMA Band I - EUROPE JAPAN & CHINA IMT 2100 band
[Bit_23] WCDMA Band II - US PCS 1900 band
[Bit_26] WCDMA Band V - US 850 band
[Bit_49] WCDMA Band VIII - EUROPE & JAPAN 900 band
I'm guessing the reason some of us are having issues on Tmobile is that the AWS bands are missing? Can we enable them somehow?

It could possibly be activated using QPST, but there are other steps to do it. The only issue is that since QPST is the QualComm radio programing, there is potential to lose signal quality or lose all radio functionality. That said, it could also be possible to recover by flashing the original firmware or RUU to recover. I now T-mobile uses 1900 GSM PCS band and AWS 1700 mHZ. There is another program I use to actually enable more bands. The program basically converts the selection of bands to a hexidecimal number to use in QPST software to program the added bands. Again, not sure if the Qualcom chip can use it. There is a WCDMA band selection for Bit (25) IV- US 1700 than could be programed to enable. I used a thread from the Sony Xperia forum to help me use the two programs.

There's a solution for this problem, if you are s-off-ed. I also did the same thing - i selected USA bands and my phone radio died. Just make a nandroid, flash ARHD , go to the same 4636 menu and it will give you another option in band selection - Auto!! Choose auto, then reboot and make sure you have connection with the network. Then restore from nandroid and you're good to go! I will try to find the link to the original thread!

Thanks that was helpful! Somehow I also had recently loaded a Xposed app to show CPU speed on the top bar. I uninstalled that then after two reboots things came back. So odd, but I'm not complaining at this point.
after a google search it seems people have gotten into problems with chaning bands on verizon devices, the above solutions brings the radio back to life. But it certainly doesn't unlock LTE on europe bands.
So i guess its a lost cause, as it must be a hardware limitation
Yeah disappointing that we can't add those

Use to calculate Qualcomm NV items for adding GSM / WCDMA / LTE bands.
Do you want to add any GSM / WCDMA / LTE bands to your phone? Then use this app to calculate all needed NV items.
This app is only useful for phone with a Qualcomm chipset.
If you don't know how to add GSM / WCDMA / LTE bands to your phone, please refer to this thread. That thread is for S5 model, but the same principle is also applicable for many other phones, e.g. Samsung, LG, Sony, HTC, Nexus...
You also need some NV editor software (e.g. QPST, QXDM, EFS Professional...) on the PC to write these NV items to your phone.
>> NV items description:
- Adding GSM / WCDMA bands:
NV 01877 - RF Band Configuration

This app can show the calculation result in 3 formats: Decimal, Hexadecimal and Byte-swapped Hex.
Update v1.0.5:
- Fix UI issue on some devices.
- Add separate notation settings for GSM/WCDMA and LTE calculation. You should not change the default settings unless you know what you are doing.
I'm intersted in Qualcomm NV access, but not for cell band issues. There appear to be GPS issues with some Samsung phones, and there is some indication that those issues are related to a NV "privacy flag". Apparently older ROMs can turn this bit on and off, but newer ROMs don't - whatever value was left there is "stranded" there. There are people flashing back to CM10.x, setting this bit, then flashing back to CM11. I'm presuming that what is really happening is that they're tweaking this on NV location.
If we could simply read the NV location, we could compare its value to GPS functionality, and see if this is really the issue.
If the above is true, and if we could simply write this one NV location, we'd have a heck of a lot simpler GPS fix.
Thanks, vndnguyen, for your app. And it would be very nice if you add CDMA bands to your app. Thanks again.
if i am interested in enabling umts bands in somewhat old msm7227a based motorola, running gb 2.3.7, with no custom recovery, no custom roms or anything, but rooted.
should i even try?
thanks for making this, i wonder if my Snapdragon 600 on LG G Pro E988 can use this to enable China's TD WCDMA and TD LTE, since FDD is kinda different than TDD

Got a question. I found a discrepancy in your calculator.... Your NV calculator values do not match the NV value of the LTE bands my phone already has. So, how can I trust the calculator to give me correct values for additional bands I wish to enable?
It's at the bottom of this post, but I am putting a lot of information about my phone first, so you know the whole situation.
I have 5.2" 1440p, 3GB RAM Moto Maxx (XT1225), which has Snapdragon 805 -- same as the (Motorola) Nexus 6. In fact it was being tested by Google to be the Nexus 6 (or a Nexus 6 variant) as late as mid-August -- but Google decided to go with the larger size variant and only the larger size variant.
Motorola re-purposed this phone as the Verizon Droid Turbo (XT1254) in the USA and as the Moto Maxx (XT1225) now being sold in a handful of Latin America countries. We already have root, TWRP recovery.
When this phone was being tested by the FCC, it had these LTE bands:
But now being sold as the Moto Maxx (SAME FCC ID number), Motorola enabled more GSM bands and changed one of the LTE bands.
They disabled LTE band 5 (a minor AT&T LTE band), and enabled LTE band 3 (which is used more in Latin America countries).
QPST confirms the 2G/3G bands Motorola now claims for this phone:
Which means the LTE bands they now claim (2, 3, 4, 7, 17) are also probably correct.
Again this phone has the SAME FCC ID NUMBER. And as it's being sold in Puerto Rico (U.S. territory), that is very important. That means there's been no hardware change since U.S. FCC certification -- only software change.
Motorola also promises it has the SAME HARDWARE (including antenna) that the Droid Turbo (XT1254) has (even though the Droid Turbo has a different FCC ID number):
This is also important. It means really, Motorola could not sell the Moto Maxx (XT1225) in Puerto Rico (U.S. territory) under that FCC ID number if any radio-specific hardware had been changed at all.
Thus, we know the additional GSM bands, change in the LTE bands by Motorola was software modem change.
With me so far?
___________________________
Now the discrepancy...
In QXDM NV browser, in Line 6828, the XT1225 phone showed a value of 65630 (for LTE bands 2, 3, 4, 7, 17).
Yet, according to your app, with THESE LTE BANDS enabled (2,3,4,7,17)...
it should be THIS value: 65614.
Now I admit that's CLOSE, but it's not the same.
Therefore, how do I trust the calculator to let me enable MORE bands if this default number does not match in your calculator?
I have edited the values of that line to theoretically enable more LTE bands, but if the beginning number from the phone does not match what your calculator number says, then what exactly have I enabled?

I don't how how many bands does your phone support. But if the value of NV 6828 in the QXDM NV browser is 65,630, that phone should support the following bands: 2, 3, 4, 5, 7, 17.
There is NO discrepancy here.

So, you are saying the phone supports LTE band 5 out of the box, even though Moto only lists 2,3,4,7,17 on the retail specs?
That after FCC testing they only enabled additional LTE Band 3, but did not disable LTE band 5?
If so, that's interesting.
Only to get you correct: this mod is only to extend the range of usable LTE/GSM bands for roaming, not to extend your connectivity while using your default provider in your home country (e.g. to get better coverage in areas where your default provider has a low signal strenght), right?

Or when changing from one carrier to another in the same country. Many carriers lock down bands the phone could receive, because they want the phone to only be used on their network.
Okay so I'm not really understanding the whole idea behind this. I have a Sony Xperia Z(C6603) and my phone already supports the LTE bands(LTE_BC1, LTE_BC3, LTE_BC5, LTE_BC7, LTE_BC8, LTE_BC20). My problem is that by default my phone and service provider should be able to have LTE working since my service provider also supports LTE band 4 and 7 on their network but upon choosing LTE network modes it has no reception at all, only 3G and HSPA. So I'm assuming I need to do additional unlocking here on my end for my phone but am not really sure why.
I'm able to access through the hidden menu of *#*#4636#*#* and change radio bands and network modes:
But I haven't changed the radio band and tested it yet because I don't know what the outcome will be and if there are any risks or hard bricking of it and don't know how to revert back to default. My service provider's network supports LTE band 4(2100MHz) and band 7(2600MHz). Would I need to go through QXDM to have these 2 frequencies enabled on my phone? Because I noticed how from the radio band list of my phone shows Euro Band which ends up to be 2600MHz but I'm not sure if that's how to enable LTE because it's Euro radio band. Am I okay as it is with my phone's default radio band and just unlock band 4 and 7 somehow through QXDM? Sorry I'm just really clueless and don't want to risk hard bricking my one and only phone.

Your provider supports LTE bands 4 and 7. Of those two, your phone can receive LTE band 7, but you don't see it. Are you sure LTE band 7 is in your area?
My carrier supports five different LTE bands (and my phone can receive them all), but in my area I only see two of those LTE bands. The others are not used in this area by my carrier (AT&T).

Yeah my carrier supports band 4 and 7 in my area, the towers are everywhere.
I checked it using this website: http://www.ertyu.org/steven_nikkel/cancellsites.html
both 2100/2600 are within all the cellular towers in my area.
edit: so if I'm able to choose LTE network mode on my phone, does that mean the LTE network mode consists of all these frequencies of LTE_BC1, LTE_BC3, LTE_BC5, LTE_BC7, LTE_BC8, LTE_BC20? So everytime I change to LTE only or LTE/GSM etc etc, automatically my phone has 2100MHz and 2600MHz included? Which means I don't need QXDM to unlock anything further? It might just be a sim card defect or something maybe. Sorry I'm just trying to understand more
Hi
I am trying to use a US note 3 (n900a) on Europe, but I frequently lose connectivity (although bars are full). The only solution I found is to fix wcdma to 2100 freq, however this also means that I lose reception when there is only GSM coverage.
This app seems to be the ultimate solution for me to calculate a custom NV for GSM+wcdma2100. Am I right?
If so, may I use a NV writer without a box, by just using my usb cable?
Thanks a lot

I brought back a Pro 2 F350L from Korea because it was listed in swappa as the Att device unlocked. I took it to T-Mobile put in a sim card which automatically chose the appropriate apns. I only get 3g no lte. I have scoured the web and these forums but cant find the info that tells me wether i got the wrong device for Tmo bands. I need help either configuring the correct bands or correct radio to flash or if this device won't or can't get lte on Tmo network. I am more than happy to reward the parties or person who helps me figure out this problem. If i have the wrong phone then so be it i will get the other model (that gets tmo lte) and unload this F350L. Thanks for any and all help.
In network mode, do you have GSM/WCDMA/LTA auto to select, or just GSM/WCDMA auto?

Looks like you have the wrong phone ... https://support.t-mobile.com/message/435224#435224
Bottom line, for optimal utility a T-Mobile phone needs to be:
1. Quad-band GSM
2. HSPA+ on at least band 2, band 4 & band 1 (2100) for roaming.
3. LTE on bands 1, 2, 4 & 12.

So seeing the bands I posted would the phone work for ATT? Thats a huge question because it (350L) is posted on Swappa a a ATT phone? At least I can unload it there, LOL.

"AT&T 4G HSPA and HSPA+ use 850Mhz(Band 5) and 1900Mhz(Band 2) bands but it all depends on area if they own a license. LTE uses Band 17(700Mhz), Band 5(850Mhz), Band 2(1900Mhz), Band 4(1700/2100Mhz) currently."

Hello fellow xda users,
I am currently trying to buy myself a 4G LTE modem, and I'm looking into buying one from China, since the devices I need here cost 200 euros and up, whereas from Chinese retailers they go as low as 67 euros.
The only problem I'm having is choosing a device which supports the correct LTE Bands of my country.
Here in Lithuania I am using services of the carrier name BITE. According to https://en.wikipedia.org/wiki/List_of_LTE_networks_in_Europe (Country: Lithuania) BITE provides users with LTE bands 3, 7 and 20. (1800, 2600, and 800 Mhz respectively). And they sell their expensive SIM Modem devices (such as Huawei E5186s-22a) which support bands LTE FDD DD800/900/1800/2100/2600MHz, TDD 2600MHz (bands 3, 7 and 20 are included).
Whereas the products offered in China have support of only 2 of the 3 bands listed.
Not sure if I'm allowed to share product links here, but here we go:
1. http://www.aliexpress.com/item/5200...-Hotspot-Portable-Power-Bank/32315152662.html
2. http://www.aliexpress.com/item/3G-M...ower-bank-3g-wifi-router-with/1881314121.html
As you can see, both these devices support Band 3 (1800Mhz) and Band 7 (2600Mhz), however the support for Band 20 (800Mhz) is not listed.
So I'm not sure where to go from this point.
I am using my Xperia Z1 (C6903) phone from the place where I want to use the 4G SIM Modem, and my phone is showing me that it is using 4G network (3/5 bars) on BITE network.
However I'm not sure, which bands are being used in that area? It's AROUND the capital city of Lithuania. The network map of the carrier BITE shows that the city is fully covered in 4G+ network, whereas the outskirts of the city are 4G only -- and my phone proves this (4G works both in and outside the city, can't test the LTE).
In the end what I fully want to know:
Will I have 4G internet access ordering one of these devices that support bands 3 and 7, but not 20?
Will I be able to connect to the Internet at all?
Is band 20 (800 Mhz) that critical for 4G to work with this device? Or should I just spare the extra hundred more euros and buy the carrier certified device?
