[Q] list of bands/freqs per region

So I'm looking at GSM arena, and it says 4G Network LTE 700 (region specific) - I've googled everywhere and I can't find a list of the different versions/regions/varieties of nexus phones that are coming out. Am I just a bad googler? Or is there really no details out there showing which phone(s) sold in which countries have what bands in them?

bump. anyone's google searching better than mine is?

as far as i've seen there is only one GSM variation released so far and its an unlocked "european version". i have it and it works pretty well on tmobile.
Taking from Expansys a big retailer for this device currently shows:
HSPA+ 21Mbps/HSUPA 5.76Mbps 850/900/1900/1700/2100 / Quad-band GSM/GPRS/EDGE: 850/900/1800/1900 MHz / (Band frequency, HSPA availability, and data speed are operator dependent)
http://www.expansys-usa.com/google-nexus-prime-android-smartphone-unlocked-16gb-224148/
The Newegg listing for this device shows:
GSM 850 / 900 / 1800 / 1900 MHz
UMTS 850 / 900 / 1700 / 1900 / 2100 MHz
http://www.newegg.com/Product/Product.aspx?Item=N82E16875176322
Hope that helps! Definitely a great device!

OK. Was wondering if any of the variants had both GSM and some flavor of LTE in it. Thanks for the input.

No. Not yet. Or maybe never. There are several versions of nexus but as of now only two known variations concerning radio.

[Q] the htc one x on t-mobile?

I'm sorry that I'm a newbie at this with discussion boards and forums.
I want to know:
1) what if I was to purchase the AT&T version of the htc one x and get it unlocked to use it on tmobile, would it work well like the other smart phones tmobile would have (example: compared to the htc one s)?
2) what about the international unlocked htc one x on tmobile? I know that the international unlocked one x has a very different processor compared to the at&t one. So what would the speeds be like on tmobile with the international unlocked version?
Basically comparing the AT&T htc one x and the international unlocked one x on tmobiles network.
I really want the one x, I know tmobile will release the one s, but that version is a whack to me.

Ok, so there are three basic differences between the One X (international) and One XL (AT&T):
- the processer: quad core Tegra 3 vs. dual core Snapdragon S4 // the Snapdragon is faster, but the Tegra's GPU is faster
- LTE: 3G only vs. 4G //the One XL wins, if T-Mobile offers 4G in the USA, you're better off with a XL
- the AT&T will have branding, if not hardware then software, which means you will have to wait for updates much longer
anyway, both phones will work with T-Mobile, no problems here.
Bottom line:
if you decide to get the XL, try to get a branding free version, e.g. from amazon.

Thank you soooooo much! Now I can make a better decision with your wise info/suggestions!

The international version will NOT GET 3G on T-Mobile. The AT&t version MIGHT.

AT&T is getting the One XL. It uses the 700ishMHz band only for LTE. It doesn't support T-Mobile U.S.' AWS (3G/Faux-4G) bands and would only get GPRS/EDGE data speeds.

Actually, I wouldn't be so sure on the AT&T version yet. Despite what the HTC Asia site shows, the HTC US site shows differently. We won't know for sure until the device's release.

Let me know ahead of time so I can know which to get. The release dates are out already for the AT&T htc one x. May 6th. Preorders are available April 22nd. If anyone of you are going to test it out or something.

What discrepancy? It says 700mhz AWS but T-Mobile uses 1700 for AWS.

AWS is a combination of the 1700 and 2100 bands. ATT is deploying LTE on both the AWS and 700 MHz bands. The question is if it can pick up UMTS on the AWS bands or not.
For what its worth, the internal ATT "coming soon" data sheets don't list AWS UMTS support.
Sent from my HTC One X using XDA

AWS bands service ranges from 1710 MHz to 2180 MHz. When talking about AWS bands they're talking about 1700/2100 MHz.
The Advanced Wireless Services (AWS) is in the 1710 – 1755 and 2110 – 2155 MHz spectrum range. The most common use of AWS spectrum is fixed and mobile voice and data services, including cell phone, text messaging, and Internet.

HTC Asia doesn't show AWS being listed on WCDMA, while HTC US does.

HTC US shows 700/AWS... I don't think it means 700 mhz AWS, it could be possible that it means 700/AWS(1700 or 2100). If we base on FCC's definition of AWS, then 700/AWS defintely doesn't mean 700mhz AWS.

Traveling to Korea with the S 3

Hey all. I am looking to purchase a galaxy s 3. Would a t mobile galaxy work over seas or do I need an international one? Thanks.

Yes, it will work. The T-Mobile S III has quad-band GSM/EDGE/HSPA+ support.

So in that case id be better off buying one out of contract and using one of the Korean providers when I go over seas? Do you know if the international one would work?

Either version will work. Both are quad-band GSM/EDGE/HSPA+. The difference is that the T-Mobile version supports 1700 MHz HSPA+, while the international version ditches that, and supports 900 MHz HSPA+ instead.

Those are just bands that the phones support. And GSM is a world standard, it should work in Korea, and HSPA+ should work too as it supports the 2100 MHz band.

Wifi calling is an option too.

[Q] Can I use a Korean note 2 in the US?

I recently purchased a galaxy note 2 in Korea and I would like to bring it back and use it in the states with AT&T. I read that 4g would not be compatible with the phone but 3g will work? I plan to use this phone for business and I realized the 1 is not designated as voicemail due to it being a Korean phone. Is there way to add this feature on? Are there any other features that I will not be able to use with AT&T? I realize I won't be able to watch tv on my phone anymore.

If that's the international version Note II check and see what frequency's it supports,and compare to AT&T or T-Mobile's. International devices are not carrier locked
If it's a branded phone meaning you got it from your cellar carrier, It could be locked to that provider only.
If your using the unlocked phone, look up the specs on your device and see what it supports, if it matches up to the above frequencies you should be good

Just reading the specs I would go with T-Mobile, Faster HSPA speeds if you decide to keep your amber brown. Only downside is T mobile's coverage isnt as good as AT&T but if you re in a major city it shouldnt be a problem.

[Q] Can I use an unlocked HTC One with Verizon?

I was wondering if I purchase an unlocked HTC one, will it work with Verizon?

You have to see the frequencies of the carrier
But, probably, yes!

in a word, no.
It has no CDMA radio, which is required for voice. Not to mention VZW hasn't ever let you bring a device to their network from the outside.

VZW uses two different technologies.
the voice is carried on CDMA as is their 3G EVDO data.

Hi, it looks like I'm reviving this thread...
I've done a bit of homework and on htc.com the One specs are as follows:
2G/2.5G - GSM/GPRS/EDGE:
850/900/1800/1900 MHz
3G - UMTS/ HSPA:
Europe/ Middle East/ Africa: 900/1900/2100 MHz with HSPA+ up to 42 Mbps
Asia: 850/900/1900/2100 MHz with HSPA+ up to 42 Mbps
Canada/ Latin America: 850/1900/2100 MHz up to HSPA+ 42 Mbps
T-Mobile (US): 850/ AWS/1900/2100 MHz with HSPA+ up to 42 Mbps
AT&T: 850/1900/2100 MHz with HSPA+ up to 21 Mbps
Sprint: 1900/2100 MHz with HSPA+ up to 14.4 Mbps
3G - CDMA:
800/1900 MHz for Sprint
4G - LTE:
Europe/ Middle East/ Africa: 800/1800/2600 MHz
Asia: 1800/2600 MHz
T-Mobile (US)/ AT&T/ Canada/ Latin America: 700 MHz and AWS band
Sprint: 1900 MHz
On the Samsung Galaxy S4 for Verizon:
LTE, CDMA/1xEVDO Rev. A (800/1900 MHz)
Global Network: EDGE/GSM (850/900/1800/1900), HSPA/UMTS(850/900/1900/2100)
It looks to me like the phone supports all ranges and has both styles/types of radios. Has anyone been able to get an unlocked One working with Verizon? Does anyone know how to do it? If I buy an unlocked One, would it come packed with all the network support as listed above or do they manufacture them with only a specific radio/frequency range in mind?

Nope

Stop nope, just no.
Verizon and Sprint use CDMA as their base on their Network. The only HTC One with CDMA is the Sprint version. But you can't use the Sprint version on Verizon.
That's why when the Sprint version was released developers had to tweak their roms and recoveries since the outside was the same but the insides no.
Yes LTE is gsm based and requires a GSM radio. And yes when the Verizon HTC one is released it can be used on TMo and AT&T. Since it has both CDMA & GSM radios.
But NO NO NO you CAN NOT use a AT&T, T-Mobile, Dev Edition,Sprint, or Iternational HTC One on Verizon.

which is required for voice.

Until Voice over LTE is fully implemented voice is still falling back into CDMA.

Thanks for your help! I realized I was misunderstanding the way those specs were written, thinking a single phone carried all those ranges and could work equally across the board.
I'm leaning towards getting an unlocked phone for T-Mobile. Any suggestions on where to get it from? If I get it from T-Mobile then it will likely have bloat on it which I don't care for. I could get it from Google Play or HTC's shopamerica...Is there an "easy" way to determine whether or not a phone will fully function on a particular network? Clearly my line of thinking on just making sure the frequency ranges match up is rather off!

Depends what freq your carrier uses for 3G etc. Only the international and dev edition are bloat free. But your at xda there are threads all over the place to help you debloat.
Again T-Mobile is the only one with 1700 3G band.
The dev doesn't have 1700, but has other extra bands. And the international lacks LTE.
Only Verizon will sell their version of the ONE. All the others are all over the internet.

So if I travel internationally and want to have the use of LTE, it sounds like I would need to get the unlocked "international" One? If the so-called "developer" version of the One doesn't have the 1700 band, will one of the other bands take over/compensate? In other words, will the developer phone still be fully functional? I also assume that by "developer" phone you're referring to both the unlocked 32 and 64Gb phones sold at shopamerica.com?
Lastly, here's what I'm doing: I want to buy a phone that I can use in the US and if I travel to Canada, I want to make sure it is compatible with their networks too so all I would need to do is pick up a new sim card and be off to the races. If I'm understanding everything, then the phone on shopamerica should be sufficient.
Any thoughts? Thanks again for the help! I've never dealt with network matching and unlocked phones. Can you tell?!

Stick with the developer edition since it offers more 3G bands ... LTE outside the US it would depend if whatever carrier you use on that country uses any any of the LTE bands it supports.
A lot of the major carriers around the world use similar 3G bands most will work on this phone. Again it all depends on which carried you use.
