Zenfone 2 US/Japan Compatibility - ZenFone 2 Q&A, Help & Troubleshooting

Hi guys,
(I tried searching this and so far no answers)
I want to buy an unlocked Zenfone 2 ZE551ML.
In the US, the price is nice at $299 (for the 64GB). In Japan it's over $500 (OK, with the exchange rate it's a little less, but...).
(Sorry, the site is preventing me from including external links)
http colon //goo dot gl/ss7hV8
The problem I am having is finding out if it's truly compatible with Japanese and US carriers. I would like to take this thing back and forth.
The frequencies look right, but on all the AusTek documentation is says (JP Version) near the 4G FDD-LTE frequencies. Do the major carriers in Japan use some variant of FDD-LTE that is different from the US? Or is this only a marketing strategy?
The only difference I have seen in the past on Japanese phones is that here they always come with a TV Antennae built in for Digital Japanese TV and the freakin' Carrier charges a monthly fee for the TV app! Haha
Here's the information from Asus Japan (open it in Chrome and it will translate the Japanese for you, albeit badly):
http colon //goo dot gl/3zo5E3
Decent worldwide Frequency list:
http colon //goo dot gl/EuOKoy
Anyone try this out between the US and Japan?
Thanks in advance.

The US version is the WW version with one more band available (Band 12 I think which is used by AT&T in the US). Weird that the US version has more Bands than the World Wide version. So if the WW version works in Japan, the the US version will as well.

Thank you for your quick response!
I just really want to make sure that there aren't different versions of FDD-LTE frequencies. Some kind of encoding that's different or something. The thing that keeps throwing me is that on all the specification lists from Asus for the Japanese versions it says "(JP Version)" next to FDD-LTE.
From the Asustek Japan website:
2G :
EDGE/GSM :
850/900/1800/1900,
3G :W-CDMA 800(6)/850(5)/900(8)/1900(2) /2100(1)MHz
4G :
FDD-LTE: (JP version)
2100MHz(1)/1900MHz(2)/1800MHz(3)/1700/2100MHz(4)/850MHz(5)/800MHz(6)/900MHz(8)/1700MHz(9)/800MHz(18)/800MHz(19)/700MHz(28)

I also looked on the wiki article of LTE bands and I don't see any special notes for LTE in Japan so it's probably fine.

If it's any help, I am using in Japan using a ww ZE550ML bought from Expansys. I use it with an OCN sim (so it's on the docomo network). It works fine as it has the main docomo LTE band (band 1). The only problem is there are a few signal blackspots where it would be better with the so-called "platinum band" (I forget which band, but it is one my phone doesn't have).

I think I will try it out. I spend a most of my time in Tokyo and only some time in Kyoto and Nagano.
I made a spreadsheet of the carriers and different phone variants. The only LTE bands the Japanese variant has that the WW version does not are:
Docomo uses band 19
Softbank uses band 8
But the rest overlap.
For 3G W-CDMA both phones have 2100 so it should work fine.
Thanks for your input

Yeah, it has 3G 2100 but not 800, so 3G can also be a bit patchy. Not having LTE 19 is mostly only a problem inside big concrete buildings. On docomo LTE Band 1 2100 is the main band so mostly you'll be fine. Highly recommend OCN Mobile One as a carrier - dirt cheap, really flexible, solid service (NTT group, so seems like docomo don't screw them over).

[Q] Use T-Mobile Samsung S4 on AT&T

I plan to buy the T-Mobile Galaxy S4. Worried that I may not be happy with T-Mobile's coverage is it possible to use it on AT&T's network? If so will it be able to pick up all bands?
Yes

So, does the S4 follow the S3? Will a T-Mobile S4 work on all other carriers in the US and Canada, but, just not have LTE speeds (Only HSPA+)?
Thanks!
According to [1] the t-mobile version of the S4 has the following LTE bands: 1/2/4/5/7/17, which correspond to 2100 1900 1700 850 2600 700MHz.
- Bands 1 and 4 are clear, as those are the main t-mobile LTE bands.
- Metro PCS uses band 2, so given the pending merger to t-mobile, this makes sense as well.
- Band 17 is used by AT&T, which would hopefully mean a T-Mobile Galaxy S4 can be fully used on AT&T including LTE.
- Band 7, is commonly used around the world, including Canada, some countries in South America and Asia and many countries in Europe. So this should allow for using the device in many countries abroad e.g. through roaming, or buying a pre-paid sim when overseas on business or holidays.
But why did they include Band 5? According to wikipedia [2] that band is only used by very few carriers around the world. Would it have not made more sense to include e.g. Band 3 (1800MHz), which is commonly used for LTE in Europe and Asia, including most of the European T-Mobile networks. That would have allowed for much broader roaming.
Furthermore, can someone confirm that the information on the webpage is correct and particularly that T-mobiles S4 really has band 7 (2600MHz) included?

Theoretically, yes, it should work on AT&T fine as the device does support all of AT&T's bands, including their LTE bands. Of course it needs to be SIM unlocked in order for you to be able to put an AT&T SIM in it though.

2600 mhz band and is for T-Mobile in European Union
To your question why. .....if they did include this to American version S4 then there will not be difference to international S4 LTE version. ....There is two different devices 9500&9505...it's a market democracy that separate this market for known reason. ....otherwise ....There is going to be way some time on road to flash different modem to give you other bands. ....flashing modem will not make hardware frequency to make changed. ...
Just follow XDA there is a lot of smart people out there that will make them

T-mobile mostly uses the 1800Mhz band in Europe (UK, Germany, Croatia, Hungary, Netherlands and Czech Republic) although it does have some licenses for the 2600MHz band as well. 2600MHz is heavily used by other carriers in Europe though, which is why I was interested to get a confirmation that the t-mobile US version of the Galaxy S4 really does have that band included, as I will likely want to use it in Europe too.

If you go to US tmobile website and go to specification you will see exactly what you looking. ...just remember there is also important to look for given band on frequency you will operate in Europe. ..my note II Was running fine on A1 Austria Tmobile Orange and tele ring company. ...When I was in Europe. ...in Australia I was not capable running LTE be cause I do have 2600 MHZ frequency just no band for Australia. ....
There it pulled T-Mobile
Bands and frequency

So if you looking for carrier that operating on 1800 it will support only GSM .......GPRS data
On other frequency you should pick high speeds data

Ah, looks like they have updated their page to include more details now. When I looked a couple of hours ago it still only said "LTE compatible" with no indication of the exact frequency and bands it supports.
As the specs on t-mobile.com and samsung's us page now match in claiming it does have support for band 7, I'll assume it actually does. But given that the AT&T page still claims the S4 has FM radio and the supported LTE frequencies of the AT&T spec page don't match the Samsungs's spec page, it seems even the "official" specs can't always be trusted.
Thanks
Here is what the Canadian versions use:
GSM Bands:850/900/1800/1900
HSPA+/HSPA Bands:850/1900/2100
LTE Bands:2100/2600
So the T-mobile version should work no problem in Canada if we end up with a bootloader locked version up here.
Well, it looks like the Tmobile version of the S4 may be the one to get for a lot of us on ATT and in Canada since it has the right bands and the bootloader isn't locked. It just needs to be sim unlocked.
i am very interested in this option. I guess what we need is some confirmation from folks in the field/first hand experience.
I guess we need to wait for someone to sim unlock and test the LTE?

Is the Canadian version confirmed to be SIM locked (the same as AT&T)?
Thanks!
Is the sim on the T=mobile version a micro? AT&T uses full size sims. Of course, getting a micro-sim from AT&T or using a sim cutter should work, but it is still a consideration. It also needs to be determined if the radio (software baseband) of the T-Mobile S4 takes advantage of the Hardware frequencies the phone supports. In other words, will it be optimized for AT&T networks.
The next important question is - how do you SIM UNLOCK the T-mobile S4?
If T-Mobile doesn't give you the unlock code, then this is moot.

SIM locked it would be as always. Bootloader locked no one knows yet. SIM unlock on previous Galaxy devices has been done for free, or for a minimal cost.

I want to buy it from a US Carrier be use it comes with US Warranty. I bought Intl Note before and went dead on me...no warranty of course. I know this is rare, but having a dead $600 phone once is enough for me
Anyways, if Tmo won't provide the SIM unlock code (AT&T does), then there's no point buying it from Tmo because the phone is always locked to their network.
I would have bought the phone from AT&T, but the bootloader is locked.

Ouch, that's understandable for sure. I've been lucky that my international Galaxy S I-III are all still running well.
Did you buy it from an online store that claims to have a warranty or eBay or similar?
Sent from my GT-I9300 using xda premium
I bought the Note 1 from Amazon - the seller was selling it through Amazon Prime. When I searched for the International Note, none that I found (eBay, Amazon, etc.) offer a 1-year warranty with Samsung USA.
Interestingly, I used to buy the International version of Nokia phones (remember those good ol day?) and Nokia USA WILL honor the warranty (I have to ship it to Melbourne, FL).
I wish Samsung USA will do the same or have a local Samsung store, like Sony Store so I can buy the phone full price from them and have full warranty. Heck, even Amazon and NewEgg are selling the Xperia ZL unlocked with US warranty! Right now my options are limited (AT&T have locked bootloader, T-Mobile SIM locked, I don't want CDMA phones).

[Q] LTE Network

Hi,
I want to buy the htc one m8 from the usa (verizon, at&t, sprint, t-mobile etc...)
I'm from europe and in my country lte will be available in 1800 and 2600 (band 3 and 7)
I've got comfused from all of the specs, so which variant htc support band 3 and/or 7?
Thanks for your help
Don't buy a USA phone to use in Europe they're different for a reason. The Asia version is more likely to be compatible with European bands.
Certainly not Verizon or Sprint!

Having a warranty and full support from HTC is more than worth the money IMO
I'm from Israel, we don't have an offical HTC in here so it doesn't change a lot. I will probably also install roms so the warranry isn't that usefull :/

Agree. Plus, not sure if the OP intends to root or not. But left stock, the AT&T version in particular has critical functions disabled (WiFi hotspot); and you will also typically not receive OTA updates outside the US. I'd stay away from buying the AT&T variant for use in other countries, unless you have a definitive reason to pick that variant.

Why would you assume that? According to the following Wiki, those bands are not supported in the US:
http://en.wikipedia.org/wiki/List_of_LTE_networks#Americas
According to gsm arena, the AT&T and Verizon variants support LTE 1800 and 2600 MHz (bands 3 and 7, respectively); probably for international roaming purposes. But I'd still recommend buying the Euro or Asian version over either of these. And gsm arena is not always 100% accurate, so I'd take it with a grain or salt and research more before making any decision:

Thanks for your help, but again, I know buying it from europe or asia is the best solution but in that case i wont get 32gb and it will cost me 300$ more, It just doesn't worth it since lte is still not available and it will be only in israel by the end of 2014. And i will install a custom rom, so OTA updates and the carrier bloat doesn't bother me that much.
I also don't think gsmarena is that accurate. accordint to htc website these are the bands:
EMEA: 800/900/1800/2600 MHz
Asia: 700/900/1800/2100/2600 MHz
AT&T: 700/850/AWS/1800/1900/2600 MHz
Sprint: FDD 800/1900 MHz , TDD 2600 MHz
Verizon: 700/AWS/1800/2600 MHz

I don't see a difference between this, and what is posted on GSM Arena (the links I posted).
AWS band is 1700/2100 MHz (Band 4). Its a bit confusing that GSM Arena lists them like they are 2 different bands. But one is used for upload, the other for download. So its not to be confused with 2100 Mhz (band 1) for instance.

You can probably find a lot of websites that have incorrect specification information on this (and other) phones. That's unfortunately just a fact. I think I've even seen spec errors on HTC's on website for some of their devices. Your best bet is to get as much reliable info as you can. Since HTC's own website agrees with GSM Arena, I'd go with those. But that is just my own conclusion.
In any case, I wouldn't recommend the Verizon (CDMA) version. You don't need CDMA, and it might introduce a whole lot of needless complications. The CDMA versions also don't seem to have quite the developer support that the GSM only versions enjoy.

Hey,
I am also looking for buying the phone form the US although I am not from there (I am from Israel as well but currently in Australia), I was thinking about getting the Unlocked version but I'm not sure which bands does it support, I tried looking on GSMarena, HTC website but couldn't find any info and when I asked the Online chat support they did not know the answer, so do you have any idea which bands the unlocked version supports and do you think there would be a problem with bands if I get it from the US and use it in Israel/Aus?, as the other user said, it is way cheaper in the US, the 32GB in the US is cheaper than the 16GB in AU!
Thanks Heaps

F400S/K/L Versions (Hardware Comparison) and usage on AT&T

Hola folks!
After finding enough screenshots/video reviews, I am beginning to think that from a hardware perspective the S and L variants are identical (including supported bands), whereas the K is only slightly different from S/L.
Any images of the back cover off on the K models (Olleh) will show "F400 0425 K" indicating the hardware is the "K" variant. (If you watch the review video http://www.androidcentral.com/lg-g3-review, you will notice this info up at the top on the backside, right above the camera.) UPDATE: Here is another link with an image http://arstechnica.com/gadgets/2014/06/lg-g3-review-a-great-phone-with-way-too-many-pixels/#image-4
On the S/L (SK Telecom, LG U+) models, they say "F400 0423 S/L" on the SK Telecom model ("S" variant), and "F400 0425 S/L" on the LG U+ model ("L" variant). You can find images of the "S" model with engadget's review (http://www.engadget.com/gallery/lg-g3-review/2676959/#!slide=2676963), and images of the "L" model with ubreakifix's F400L teardown (http://www.ubreakifix.com/blog/wp-content/uploads/2014/05/ubif-g3-21.jpg).
(Thanks and kudos to the review sites and teardown site for the images.)
As an owner of the F400S, I can tell you that all 3 variants will run on AT&T LTE (as a lot of our LTE is on Band 17 - 700 MHz spectrum). I was able to load my F400S with the TOT and DLL files of all 3 variants (currently waiting on getting it back to the "S" variant once the DLL is posted), and all 3 variants will connect to AT&T with no issues (for those of you that plan on importing like I did).
So for those of you who managed to brick your new G3, as long as you can ADB into it, you can edit your build.prop file with the corresponding korean variant model info, and load any stock image. As @wolfgart has posted a great thread with the TOTs and DLLs, I recommend swinging through there for more info. If you have a K variant, load the K TOT and DLL, and you are fine.
For those of us with S/L variants--with the above info and enough tinkering in the hidden menus of all 3 variants, I can tell you that from a hardware perspective these two models are nearly identical. From a modem/supported frequencies perspective, the S and L variants support the exact same frequencies--meaning, if you bricked your S or L version, you can restore it with an S or L TOT and DLL (after editing build.prop if needed) and you will still get all of your original hardware supported bands/frequencies. This is critical for those of you using LTE Band 5 to connect to your data... (should not be the case for any US AT&T users...).
UPDATE: in the 'Android Development' section, wolfgart's thread with the TOTs and DLLs have been updated to now include the files for all 3 models. So unless you know what you are doing with a build.prop edit, probably best to stick with what came with the phones for those who are new to this stuff.
The main difference between the S/L and K phones in frequency/band support is that LTE Band 8 is supported on the K model only, whereas you will get LTE Band 5 support on the S/L models. All other bands and frequencies (WCDMA/GSM) are the same across all 3 models. All 3 also support LTE Band 17, and will connect to AT&T in the US.
Took me a while to figure this out, but I had a long weekend
Cool! nice to know, thanks for the well explained post
Any thoughts about the L/S version suporting LTE Band 7?
Thanks

Unfortunately, I don't connect to LTE with band 7 so I can't say much on that. However, just based on the hidden menus in both (I am using the L version on my S variant phone at the moment), they both have the same listings of 1,3,5,7 for supported bands.
LTE 700, 850, 1800, 2100, 2600 (Band 17, Band 5, Band 3, Band 1, and Band 7 respectively)
UMTS 850, 1900, 2100
GSM 800, 900, 1800, 1900
The above are the fully supported bands on the S and L variants.
The below are the fully supported bands on the K variant.
LTE 700, 900, 1800, 2100, 2600 (Band 17, Band 8, Band 3, Band 1, and Band 7 respectively)
UMTS 850, 1900, 2100
GSM 800, 900, 1800, 1900
I don't have the K variant on my device now, but I recall the only band difference is that it supports LTE band 8 (900 MHz) instead of LTE band 5 (850 MHz), but other supported bands are the same. LTE Band 5 is one of the primary bands for both SK Telecom and LG U+ (which partially explains why the two phones have nearly identical hardware, including modem support).
Hope this answers your question. As support for those frequencies are built in (and it makes sense on LG as a mass manufacturer--They can use the same modem and just rebrand it like they did in Korea for the S and L variants).
Why is the S one more expensive than the L?

That, my friend, is a question you will have to ask LG and SK Telecom. We sorta see that in the US every so often with "special editions" that aren't really that special and they will add an extra 100ish.
Off-contract, LG U+ is the most affordable right now, with SK Telecom right around $700 USD. With markup and shipping, etc. eBayers are selling it for $750-800.
Also, you have to remember the G3 is a hot commodity even in Korea right now. Had some friends who thought it was funny I got a phone overseas before they even bothered joining the bandwagon.
So though I can't say for sure why exactly it's more expensive, I can definitely say it has to do with the fact that the phone is still only 3 weeks old
And none of those 3 will work on T-Mobile LTE which needs 1700 and 2100Mhz most of time.
There are some spots with 900Mhz support though.
But as much as I want G3, I'll wait for the T-Mo version.
Yeah...I'm a proud owner of a Htc One M7...I have been thinking a lot and decided that it's time to change. I'm comparing the M8, the Z2, the G3 for a long time and finally think that this last one will be the one...unfortunately it's still very soon to easily find information regarding this phone online...
Your information helped me a lot...now I know exactly which variant to buy :fingers-crossed:...thank you guys very much

It looks like you are planning on doing the same upgrade I did. I still have my M7 as my backup , but definitely gotta say I am loving my G3.
That's amazing man...I've been a HTC fan since the Sensation...but currently I feel that they are been left behind...
I'm really sorry, but other brands are offering a lot more for the same price.
The HTC will always win in design and the quality of the phone's body, screen and, of course, sound!...but they are losing in the rest...UI, camera, battery life definitely...it's just sad
Nice to know that you're enjoying your G3...I hope I'll be as happy as you are in a few weeks...and judging by how much I've researched about it...I'm sure I'll love it!!!

question
sorry, which of these three variants brings FM radio? K, L, S, and if for example buy the K version, if you install the L or S variant fm radio works?
I´m about to buy a G3 and found some model have an antenna, is that correct?, anybody knows what tv frequencies can handle?. Thanks!

From my research, none of the korean models (F400 S/K/L) support FM radio. Instead of an FM radio tuner, they are offered with Korea's DMB tuner, for korean DMB support.
I have only seen DMB function while in Korea and Japan. Anywhere else in the world, you will have to check with local providers, as some countries will charge for DMB as a service (just like satellite television).
Hope this helps

The only frequencies it can support is anything broadcasted as DMB. Certain countries offer DMB subscription services, but you will have to research if it is offered where you live.
In the US, DMB is unavailable so I just have a nice long antenna that people crack up at in the year 2014, but completely unusable where I am. I just tell them its for better service as a side joke lol

Any of them will do. I would say go for the one that gives you the best price. At this point, enough AT&T users have gotten their hands on all 3 variants. Most can get LTE through band 17 (700 MHz) which is available on all 3 phones.
Will the D855 variant (with LTE 700MHz) be able to use on AT&T (band class 17) or Verizon (band class 13)?
Or to be more specific, will the D855 cover all 700MHz US band class (12, 13, 14, and 17)?
Thanks!

You would have to check which specific band class of 700 MHz the D855 would be capable of connecting to. As I do not have the D855, and specs are varied on the internet right now, I cannot say for sure.
The FCC had ruled four separate band classes to operate on the 700 MHz spectrum in America--Band 17 700 MHz capable modems cannot connect to any of the other 700 MHz band classes and vice versa. (It was claimed that they did not want to have any network interference issues. Carriers purchased the rights to access certain chunks of the 700 MHz spectrum, and they are isolated to those carriers only.)
I am seeing 700MHz (B28) support on D855 models, but I believe that might be related to certain LTE-A rollouts in Europe (meaning it may not be able to connect to current 700 MHz bands in the US (as the US does not have LTE-A networks at the moment) and new band classes are issued for LTE-A (i.e. Band 28).

[Q] Asus Zenfone 2 ZE551ML MODEL ASUS_ZOOAD 3g

I need help, i want to buy a zenfone 2 from alegrecompra, but i dont know if the version Z00AD support 3G wcdma, i live in latin america.
Does anyone has bought this version?
I made a similar question but nobody answered.
I understand that if your buying it from a Chinese based site you will get the CN version.
CN version definitely lacks many LTE bands support compared to TW or WW version, but apparently it supports the same WCDMA bands as the others, and, on top of that, it also supports TD-CDMA bands only useful in China, but never got any confitmation first hand, only real way to tell for sure would be if someone with that CN version confirms they get WCDMA coverage with a provider using the same bands as your company...
It would be wiser to get the TW version instead but its harder to find an online store selling it apart from eBay sellers and also it should be a bit more expensive I guess...

H+ 3G WCDMA 2100 on CN version working confirmed. Haven't tested the other bands, but if 2100 is working the other ones should be too.
Thanks! I think its safe to assume then that WCDMA support is same across all regional versions...
Work here in Mauritius but not on all operator. One operator it show the H but download is 2G

It works on 3G WCDMA, I just bought the CN version and it working on band 1900.
@OP
I suggest you buy the Zenfone 2 that you mentioned in your post. That is an America Version that can be used in Latin America as well.
IMHO, do not buy the China or Taiwan Variants as those were specifically for Asian Continent.
Good Luck.

The only Freq/band that the Z00AD (WW) doesn't support that the US version supports is 700 MHz/Band 17 -- there are some South/Central American providers that use that frequency, but not many.
Here's the breakdown of frequencies from the ASUS site:
2G :
EDGE/GPRS/GSM : (WW version)
850MHz/900MHz/1800MHz/1900MHz,

900MHz/1800MHz, Class
3G :
WCDMA: (WW version)
850MHz/900MHz/1900MHz/2100MHz
WCDMA: (TH version)
900MHz/2100MHz
TD-SCDMA: (CN/IN version Only)
1900 ~ 2100
4G :
FDD-LTE: (TW version)
2100MHz(1)/1900MHz(2)/1800MHz(3)/1700MHz AWS(4)/850MHz(5)/900MHz(8)/1800MHz(9)/800MHz(18)/850MHz(19)/700MHz(28)

FDD-LTE: (TH version)
2100MHz(1)/1800MHz(3)/1700MHz AWS(4)/2600MHz(7)/900MHz(8)/800MHz(20)
FDD-LTE: (CN version)

Does the USA T-Mobile version supports LTE band 20 (800 DD)?

I wanna buy this awesome phone from eBay and use it in my home country - Czech Republic, but there are still two things I don't know, so I'm holding off.
Can anyone, who owns the USA T-Mobile (1789-04) version, check for me, if it supports LTE band 20 (800 DD)? I scour the internet for the answer and some sites says it does, but some it doesn't.
And a lil' bit stupid question: Is there a chance, it will work locked, if I will use it with Czech Republic T-Mobile sim card?
Thank you all in advance for any answer.
as far as i can tell the T-MO variant does in fact support band 20, and the spec sheet from t-mo says the same.
https://support.t-mobile.com/docs/DOC-36016
That's what I thought too, but their normal website (where you can order Moto Z2 Force online) says otherwise (can't post link):
Frequency
LTE: 1, 2, 3, 4, 5, 7, 12, 13
According to this Network signal guru app, it looks like my T-Mobile version of the Z2 Force supports band 20.
Thanks for the info. I found on Reddit, that it should work like this: T-mobile only lists the ones it's network uses. If it's roaming it will use the other bands, or if you flash unlocked firmware it will be able to use those bands as well.
So according to this, the "other bands" should be listed on every phone's tech specs T-Mobile website.
