[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.

Okay, I checked and the Frequencies are the same but HTC One unlocked says nothing about CDMA. Thanks for the help

VZW uses two different technologies.
the voice is carried on CDMA as is their 3G EVDO data.
LTE is used, but not the same bands as AT&T or T-Mobile.
The only major carriers in the US on GSM are T-Mobile and AT&T (and their mvno's)

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
No
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.

[Q]Google Nexus 2013 LTE support in EU + warranty

Hello,
My uncle from Chicago can buy me new Google Nexus 7 with LTE support. If it comes to GSM and HSPA+ are the same in US and EU.
North America:
GSM: 850/900/1800/1900 MHz
HSPA+: 850/900/1900/1700/2100 (AWS) MHz (Bands: 1/2/4/5/8)
LTE: 700/750/850/1700/1800/1900/2100 MHZ (Bands: 1/2/3/4/5/13/17)
Europe:
GSM: 850/900/1800/1900 MHz
HSPA+: 850/900/1900/1700/2100 (AWS) MHz (Bands: 1/2/4/5/8)
LTE: 800/850/1700/1800/1900/2100/2600 MHz (Bands: 1/2/3/4/5/7/20)
But LTE is kind of different. Will it work in EU with no problem?
Also will Asus EU repair my US Nexus 7 without asking questions? If they don't care I'm getting that this week

What is your provider and where do you live ?
Edit: Seems like you live in Poland
CenterNet and Mobyland have 1800MHZ so it would work.
But I think 800 and also 2600 is used, so it may not work.

Well I live in Poland and in Ireland as well
In Poland there are 2(Cyfrowy Polsat, Plus) providers who provide LTE 1800MHz, so its ok?
I never heard of CenterNet and Mobyland
And how Asus is respecting warranty in EU? Do I need to buy some extra coverage for WW (like Apple with AppleCare) warranty?

I think it will work but I'm not 100% sure.
it could be a problem occur during exchangeable because in EU they only have the EU device so this could be a big problem

I have asked US customer support and the only info they could provide is that for all the model numbers they checked in warranty box it says "local warranty" which basically means that it's for US but Sean adviced to ask European branch of Asus if there would be any problems.
Unfortunately I will get some information on Monday because in Europe we just started our weekend
I will keep you posted!

Will the LTE version bought in the US work in the UK

I see that the T-Mobile LTE version is available in the US on the play store. It is significantly cheaper than in the UK.
I bought the v1 WiFi nexus 7 in the US and had no issues. If I buy the LTE version from the US can I assume that I can use it on a UK mobile network without issue? I presume both are gsm and there is no issue?
Thanks

Even GSM networks operate on different frequencies on different continents. LTE networks may have other frequencies than GSM networks.
I found a (german) comparisation list for LTE frequencies. For US, there are 700, 1700, 1900 and 2100 MHz listed; for UK there are 800, 1800 and 2600 MHz noted.
So, if you buy an US version, it will be useless in UK. Besides the useability, you may have to pay taxes on import, additional to p&p. Will it still be cheaper then?

For France, same frequencies than UK.
We will use someday 700 MHz also.
Some of us are waitin 4 an Euro LTE Nexus 7.

I found something about the Nexus 7 ... on http://www.google.com/nexus/7/ .
Scroll down until you see a link "Tech Specs". Open it and scroll a bit down; all GSM, UMTS and LTE frequencies are listed for different world areas.
The US and the EU version share most LTE frequency cpabilities, but the US version can operate on 700 and 750 MHz (which the EU device can't use) while the EU one can operate on 800 and 2600 MHz (which the US device can't use).
So it depends on your carrier's frequencies if you can operate an US device in UK or not.

My brother is over in the US next week and could therefore bring it back without P&P and most likely other charges.
In the UK the price is 320 GBP so the saving is around 100GBP with the currency conversion.
Currently I have my mobile with T-Mobile and a sim that I use in a mifi on Three. I am looking to move the Three mifi sim into the Nexus but I don't think that looks like it would work as it states they will use 800 and 1800. I presume that both frequencies are used?

The US device can't use the 800 MHz band, but the 1800. Maybe your carrier operates LTE at 1800, maybe not. Can't say that from here (Germany).

Going to take a chance. The US price for the LTE is cheaper than the WiFi only in the UK. Will advise how I get on

Same here Czech rep, 32 gb lte is the same price than 16 gb wifi here. But i need the 3G/4G internet can't risk it i must know

Aidenbree: this is exactly what i was thinking of doing too, so thanks for asking the question! I'm also on Three and would be really interested to hear how you get on. £100 saving is worth thinking about!

Surprisingly, the radio software is the same, in fact everything software wise is identical between both devices, there is but a single firmware for both devices. I am not even sure if the US version can't technically use band 7 and vice/versa, has anyone tried to connect to a LTE network in the EU using a US LTE Nexus 7 ? Maybe those specs are just "limited" to comply with FCC/EU regulations/certifications (Paying for the CE certification for a specific frequency can be expensive)
If there is a difference then some flag must be set hardware wise to tell the radio what frequencies it can tune to.

the radio is the same
seem they fix the band though hardware
any chance the software detect the mobile services provider to decide using which band

[Q] Nexus 7 LTE Japan to Philippines

Just a question,
I'm here in Japan and I found out that the Nexus 7 (2013) LTE Edition is quite cheaper here
than in Philippines.
Would the Nexus LTE here in Japan work on the LTE connection in Philippines?
Thank you! (Sorry if some of you find the question noob-ish, i'm just not sure)

I think it will work here in the philippines since hardwares are also sinilar and the baseband/frequency forgot the exact name

Really? I'm really hesitating right now if I really should buy or not.

What carrier are you planning to use it with? You can look up what frequencies and band that carrier uses, e.g. 850 MHz and band 1.
Here's the LTE frequency/band info: https://support.google.com/nexus/answer/3248332
North America and Japan:
GSM: 850/900/1800/1900 MHz
HSPA+: 850/900/1900/2100/AWS (1700/2100) MHz (Bands: 1/2/4/5/8)
LTE: 700/850/1700/1800/1900/2100 MHZ (Bands: 1/2/3/4/5/13/17)
Rest of World:
GSM: 850/900/1800/1900 MHz
HSPA+: 850/900/1900/2100/AWS (1700/2100) MHz (Bands: 1/2/4/5/8)
LTE: 800/850/1700/1800/1900/2100/2600 MHz (Bands: 1/2/3/4/5/7/20)

Thanks for the info.
So I'm planning to enter Globe Telecom, so does it means I can use a Nexus 7 LTE from Japan to LTE in Philippines?

Globe uses 1800 MHz as its LTE frequency, but you should check what band they use.

Ignore the LG site.
It only lists bands which are supported DIRECTLY in that region, not the bands the phone supports via hardware.
Where are you buying the phone from? The seller should list the bands on the phone, but all the bands are printed on the box itself.
The phones also say "GSM only no CDMA" but WCDMA bands even work. I don't know if CDMA or WCDMA are the same thing or not.
Keep in mind ONLY the european version (not the EAW) can be rooted right now.
Here are the bands the EAW version supports:
. GSM: 850.900/1800/1900. WCDMA: 850/900/1700/1800/1900/2100. TD-SDMA: 1900/2000. LTE: B1/B2/B3/B4/B5/B7/B8/B12/B13/B17/B20/B28/B38/B39/B40/B41

Working perfect for me here in Europe.

I answered this question earlier in your other post. Remember I own this phone on tmobile.
No one uses band 66 or 71 from what i've seen anywhere.
Tmobile uses band 4, 2 in some areas, or 12. At least from what I've seen.
You're overanalyzing things now.
I've tested the bands in the service menu.
Why don't you call t-mobile and ask them if they use a strange band like 66 in your area? I've never heard of that before.

Does the LMG710EAW really support both bands 7 and 20? My research turned up that it supported band 7 (2600mhz) but not band 20 (800 mhz) or is this just due to them only listings bands from that region?
I ordered one without maybe doing my due diligence and Vodafone UK for 4G is bands 7 and 20

I have both LMG710EAW and LMG710ULM in hands, LMG710EAW doesn't seem to support B20, as in the parking area I get 4G on ULM but not with EAW.
But it's strange as today I had a look on the original packing of ULM, it's written with B20 support???
Also from LG site, FDD 4G Networks, without B20: 2100(B1) / 1800(B3) / 850(B5) / 2600(B7) / 900(B8) / 700(B28) MHz
