Odd observation while comparing Sensation (Rest of world) vs. Sensation 4G (T-Mobile)

While surfing GSMArena.com I decided to use their side-by-side phone comparison tool. To my astonishment I found that the Euro vs. NA versions of these phones have different standby and talk times; mind you they have the same exact battery. Take a look at the screen shot I provided outlining the times.
Only noticeable difference (to me) is the 1700 Mhz band on the NA model for T-Mobile use. As a result this has me wondering what could cause these discrepancies? Is it because of network strengths/weaknesses and infrastructure?
I'm no engineer so this is just a shot in the dark and would like someone to chime in
Thanks in advance.

That's most probably a typographic error. Look carefully and you will notice that they're just the same, but inverted for 2G/3G

the 1700 band is so you can have countionious up and down data on hspa+ you cant do that on eurpean modle

close. the AWS band is actually using both 1700 & 2100. 1 is for downlink & the other is uplink. Don't remember which is which though, you'll have to look that up yourself if you want to know.
Also, both the EU & US versions of the phone have the AWS band

@xboarder56 and xnifex, your actually both right. T-Mobile USA added a second band (1700) to be able to do full duplex mode with data. Faster data rates and your phone uploads/downloads data simultaneously. FYI, 2100 is downlink (transmit from the cell site to the phone) and 1700 is uplink (transmit from the phone to the cell site).

LTE Bands for International Version

I've been trying to find the LTE bands for the International/European version of the S6/edge for a couple weeks now but have had no luck with any sites I trust. I was able to come across this site: http://pdadb.net/index.php?m=specs&...g925f_galaxy_s6_edge_lte-a_128gb_samsung_zero
Does anyone know how accurate this site is or know of where I might be able to find trustworthy specs?

Also interested in this. I might get an international version, but want to know if it will work here on the US on the AT&T network

Interested as well, if the international version supports ATT Lte that would be awesome

It means the phone(s) should work on both AT&T and T-Mobile. AT&T uses bands 2, 4, and 17. T-Mobile uses 2, 4, and 12. The International version supposedly supports 1, 2, 3, 4, 5, 7, 8, 18, 19, 20, 26.

Where there are cell towers that are broadcasting using bands 12 or 17, you will not be able to get LTE coverage, but you will be able to get coverages for towers broadcasting on bands 2 and 4. Your real world coverage will depend on where you live and how each carrier has decided to configure their networks, but you will be able to have LTE for both.
[edit] Both 12 and 17 are 700mhz frequencies, which means that indoor coverage will not be as good if you don't have those frequencies. So that's a trade-off you might want to think about before going with the International version. Though for the most part, many people will have access to a wi-fi network while at work and at home, which I assume would be where most people would be for most of their day.

From what I've been reading, WiFi calling/texting features only work if you buy a T-Mobile specific device. Any other phones used on T-Mobile won't work with WiFi calling/texting features. That alone is the reason I would not buy an international phone and use it on T-Mobile.

Hi guys,
I have noticed that the verison I can purchase in France is the SM-G920FZ-02. Is it the same thing as the SM-G920F ?
I am unable to find the LTE bands for this version...
If it is not the case, I guess i could just get the SM-G920F from another country ? I've seen it on the UK version of the Samsung website.
I'm travelling a lot between Europe and the US so it's one of my main concerns but apparently Samsung doesn't give too much information on this yet!

FCC filing show the international model will support LTE band 2, 4, 12 among others: https://apps.fcc.gov/oetcf/eas/repo...ame=N&application_id=794688&fcc_id=A3LSMG920F

Based on the info so far in this thread , it would seem like a safe conclusion that the 920F international version would indeed work fine on the AT&T LTE network

So does it support 12 and 17?? I'd be interested in getting the international for ATT. Just not sure what will and won't work

Band 17 is a subband of 12 (12 is the larger scope that includes 17 in it). The S6 920F support band 12 so it should work on AT&T just fine.
Bands 4 and 2 which are also used by AT&T are also supported according to the FCC documents so i assume the international model 920F should work just fine.
I can't be sure the same about other 920X models out there.

Does anyone know the difference between the 920F and the 9200?

Samsung I9200 is the Galaxy Mega. Is that what you're referring to?

I realised that there are commonly 2 available international versions, SM-920F (European?) and SM-920I (Rest of the world?). Wondering if anyone has the LTE specifications for the SM-920I version?
Edit (4 April): Found the answer to my own question at the Singapore Samsung website (under Specifications). So LTE Bands 1,2,3,5,7,8,12,17,18,19,26,28. No Band 4 though. I'm guessing that would greatly degrade the LTE experience with AT&T and T-Mobile?
4G+ LTE Cat 6 up to 300Mbps, VoLTE, 4G+ LTE FDD [Band 1 (2100MHz)/ Band 2 (1900MHz)/ Band 3 (1800MHz)/ Band 5 (850MHz)/ Band 7 (2600MHz)/ Band 8 (900MHz)/ Band 12 (700MHz)/ Band 17 (700MHz)/ Band 18 (800MHz)/ Band 19 (800MHz)/ Band 26 (800MHz) Band 28 (700MHz)], 4G+ LTE TDD [Band 40 (2300MHz)]

Edit (8 April): Interestingly, the Australian Samsung website for the same model (SM-G920I) shows that Band 4 is supported. I'm totally confused now as to whether this particular model supports LTE Band 4.
4G FDD LTE B1(2100), B2(1900), B3(1800), B4(AWS), B5(850), B7(2600), B8(900), B12(700), B17(700), B18(800), B19(800), B26(800), B28(700)

introducing myself and just a couple of question

Hi everyone,
I've just purchased a brand new Moto Maxx XT1250 and right after I received it, I read online that motorola isn´t going to upgrade it from 4.4.4, Is that true??
The other question i have is that when i'm conected to wifi, the mobile network just goes crazy and starts switching between all modes (E, 3G, LTE, no signal, etc) randomly, i've never seen that in any other phone, and I found it strange because it doesn't happens when I´m not conected to wifi, or at least it doesn't seems to.. I'm afraid that that may probably being sucking extra battery or not, but it's just strange. Any clue?
So for the record, i live in Argentina (South America) and my operator works under the next network bands:
2G: 850 / 1900
3G: 850 / 1900
4G: Band 4 (1700, 2100) / Band 28 (700)
The XT1250 supports the following bands:
2G: GSM 850 / 900 / 1800 / 1900 + CDMA 800 / 1900
3G: UMTS/HSDPA+ 850 / 900 / 1900 / 2100
4G: LTE (Bands 2, 3, 4, 7, 13)
So all this said.. What do you think??
Thank you and sorry for the long post.

On any Quark (XT1254, XT1250, XT1225), you can use CM 12.1 (Lollipop), CM13 (Marshmallow), Resurrection Remix (Lollipop and Marshmallow), Mokee AOSP (Lollipop), and Xperia (Lollipop) ROMs.
Plus @baybutcher27 custom kernel, one for Lolllipop and one for Marshmallow.
The XT1250 = XT1254, but with unlock-able bootloader from Motorola. Same FCC ID as the XT1254. The XT1250 was basically the "dev" version of the Droid Turbo.
How did you get an XT1250 in Argentina? I would have thought you would go for the Latin America XT1225?
Yes, the XT1225 and XT1254/XT1250 all share LTE bands 2, 3, 4, 7.
The XT1225 additionally has LTE band 5 and 17 (more bands used by AT&T here in the U.S.).

The XT1254/XT1250 instead has LTE band 13 (Verizon LTE band), plus CDMA bands. While it does have some HSPA bands, there's not as many as in the XT1225.

Hi! Thanks for replying!
That's good news because I don't won't to get stuck on 4.4.4!
I bought it in the us! Far cheaper than getting it here! I got a promotional discount and acquired it for $300
I'm on CM12.1 right now, the snapshot version.. Do you recommend any particular ROM beside this?

Very good!
I'm on the latest CM12.1 nightly (March 02, 2016), myself. A few more improvements over the last snapshot, which is a couple of months old by now.
Also the Lollipop 5.1.1 Resurrection Remix (dev @baybutcher27) is very popular as it has more tweaks than just CM, even though it's based on CM12.1.
But I stuck with CM -- even though I use @baybutcher27's Lollipop kernel with my CM12.1.
----
The Marshmallow CM13 and Marshmallow Resurrection Remix ROMs are supposedly fairly stable right now, but I'm still waiting a little while longer to try those. I'm very busy, and CM12.1 (Lollipop 5.1.1) works very well for me.

Great! thanks for the advice!
I guess I'm gonna stick with this for a while and later I'll try that combo of yours!

LTE Bands on an N920T

Going by the specs I've seen on a number of tech sites, I've always thought that the LTE bands on most T-Mobile phones were limited to those that T-Mobile and AT&T use (4 and 12). However, when I ran "search for operators" I could see Verizon (and ATT + TMo) towers. Then I found this page at T-Mobile's own website that shows this:
InternationalQuad Band GSM; LTE: 1, 2, 3, 4, 5, 7, 8, 12, 20; UMTS: Band I (2100), Band II (1900), Band IV (1700/2100), Band V (850)​​
The UMTS bands obviously are TMo's, but LTE covers way more than they have deployed. So it would seem the N920T really has these bands? Perhaps it's because the chipset is Exynos.

You can see and change the band's from the dialer using *#2263#
I don't recommend changing them but you can look at the list.
I did change the default bands to LTE/WCDMA/GSM on mine for use on AT&T

That's interesting. When I execute that USSD, it shows way more bands than I quoted from TMo's spec list:

And this continues into the 40s, I just can't remember how to screencap the entire page. I am curious if they are all actual bands you can use, or (I would assume at this point) every possible LTE band there is. But it's a feature code I haven't seen before, so +thanks.

Well, after further digging in the *#2263# screens, this definitely looks like an international kind of phone.
If the settings are to be believed, there's also support for TD-SCDMA, which is an alternative to W-CDMA (and incompatible with it). That's used in China, which is a long way off from T-Mobile territory.
But that's great -- such an enormous frequency list is exactly what a flagship should offer. And it's probably no coincidence that this is an Exynos chipset, because other phones using Qualcomm seem to have restrictions in place for the US market.

[dismiss] Those considering Dual-Sim H990DS better get H990N if you're in USA

Those considering to use the LG V20 Dual Sim in the US should pick the H990N instead the H990DS because is the only Dual-Sim version to support AT&T's LTE bands 17, and Sprints band 26, notwithstanding the DS is faster and both version support T-Mobile bands, those looking to use the 2nd sim as carrier backup service likely will pick AT&T or Sprint as secondary or main line.
The original post was based on information available from 3rd about H990DS and H990N, none indicated the N990DS to support LTE B17, while some users reported it actually support that band, information confirmed from LG's Taiwan site confirms LG V20 N990DS actually supports LTE B17, accordingly this post is unfounded and moot.
Moderators, please close thread.

Hate to burst your bubble but you are incorrect. I have the DS with both tmo and att. Grtting band 17 just fine.

According to both these sources H990DS is missing band 17. H990N seems perfect for me, it has band 17 (in addition for 2&4 for AT&T), also has band 1 that the US996 is missing which I need for the occasional visit to Japan.

Seems the H990N the best deal for Travelers.

According to LG's Taiwan website, the H990DS supports bands 1 and 17 but not 26. It's highly unlikely LG would release a phone in Taiwan that didn't work in Japan. I can read Chinese by the way.

Most if not all android phones will work in japan, 4G is not always suitable, but 3G 2100 is available and japan supports it.

LTE B17 is ONLY OPTION IN: BAHAMAS, CAYMAN IS, ANGUILLA, and JAMAICA. or 3G
Others Networks using B17 are in markets where you have at least one alternative (available on both V20s) as USA (AT&T) where you can go on T-MO where no AT&T B17.
LTE B26 only user yet is Sprint (acc Wikipedia) also only in few areas, where you also have alternatives from other networks.

its rigth, no need to speak chinese http://www.lg.com/tw/smart-phones/lg-LGH990ds

Thanks for posting the TW site. Im really happy if the H990DS supports band 17 according to the site. Not sure if all other sites are quoting frequency check, as every other site I googled quoted H990DS specs as without band 17.
If anyone has an H990DS, would you be able to check the following?
Enter Engineering mode:
On my V10 H960A, code is *#546368#*960# (Not sure if this is the right code for V20, may need to replace 960 with 990)

You should be in the "LTE information" page. It should show what LTE band you're connected to. If anyone can verify and post a screenshot and band 17 I'd greatly appreciate it.
Thanks in advance.
