Can someone please tell me if developer edition is locked to Verizon?

Hi,
I am planning to buy the developer edition and take back with me to Europe. My network provider supports:
Required :GSM 900
Recommended :GSM 900 and GSM 1800
4G LTE: 900, 2600, and 800
Based on these I assume that the phone would work with my network provider as the same freq. are supported by the phone. (though not all of the LTE freq but one would be enough).
My question is whether the phone is locked to work only on verizon or it work with any other network with similar freq?
Thanks.

World unlocked phone so it should work in Europe hussy not in USA
Sent from my XT907 using xda app-developers app

I had the pre-release developer version and used it on AT&T despite Verizon branding. Worked fine but 4G LTE is faster.
Not sure if the retail developer version will be same.

Samsung Needs To Communicate LTE

Samsung needs to tell us clearly what is what with the Note 2. If someone wants to buy an International Note 2, from say UK, and not wait till Nov., will the Note 2 from UK work on ATT with LTE? Why can't Samsung publish the radio bands for the International Note 2? I have looked at numerous websites and some list LTE and others don't, and overseas LTE radio bands appear different than ATT, as an example.It would seem we should be told what is what, so all can clearly understand what device to buy from where, if one wants LTE. I don't have on original Note, but have on S3, and totally a requirement going forward. LTE is so much much faster than 3G that I don't want to buy a Note 2 if it isn't capable of LTE that works on ATT. I rather wait till mid Nov. and get directly from ATT than get 6 weeks sooner, if it only has 3G. Perhaps I will just wait to be sure, but seems straightforward question that easily can be answered and published by Samsung.
Maybe I have missed something, but I can't find any definitive info regarding this LTE subject. Samsung needs to communicate.

I am also trying to figure out which version to buy and every site says something different,
This is phonearena which I am going off of

Additional examples, Clove UK specs say nothing about 4G LTE, yet Negri Electronics specs calls out 4G LTE...and on and on......Handtec in UK spec does call out 4G LTE, and we know Handtec and Clove UK will be getting the same device. Handtec spec:
3G: HSPA＋ 21Mbps (HSDPA 21Mbps / HSUPA 5.76Mbps) 4G LTE: 100Mbps/ 50Mbps (HDSPA 42Mbps / HSUPA 5.76Mbps)

The GT-N7105 model doesn't have LTE bands, so deductive reasoning says the N7100 model might.
...although it might not

There sure is conflicting info everywhere.
N7100 is non LTE,
N7105 has LTE
The galaxy s3 I9300 has no LTE
While their I9305 model does have LTE
Look for the 05 to identify the LTE model. Now whether a European LTE model will work in The USA or vice versa is another headache

That is the million dollar question, will the N7105 LTE model work on the LTE carriers here in the USA.
If it does that would be awesome.

I am also slightly peeved about this. Then again, it's not like I will have it in my hands the moment I know the LTE bands. According to the Engadget article it states no "US-FRIENDLY" LTE bands, which may no imply the device not having LTE altogether.

I would suspect the LTE version sold outside America will have LTE 800/900/1800/2100/2600 (meaning it will work perfectly on all LTE networks in Europe and almost everywhere else in the world) and then America will have their own versions that support your (AT&T for GSM version) 700MHz LTE band.

There are at least 5 different versions if not more. Although it is LTE capable, the version sold for England does not have a LTE chip, The German one does but it will not work on ATT. There are no LTE networks in Europe that I know about compatible with ATT LTE bands. If you buy one in Europe plan on using 3G and 2G on ATT. Make sure it has these bands:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 1900 / 2100
ATT uses 850 and 1900 for 2G and 3G. You need both.
To use ATT LTE you need a chip for this:
LTE 700 MHz Class 17 / 1700 / 2100.

You need to confirm LTE 700 MHz Class 17 / 2100 is on board the model they are selling you. There are a lot of different versions and not all have LTE chips and the ones that do have LTE chips for different areas. There is a CDMA version that US Cellular has up for preorder.

apparently there is a bunch of Gnote II types...this is just confusing why wouldnt they just have a 4g for all?
just realized the one i bought from Handtec will not have 4g/LTE
http://pdadb.net/index.php?m=specs&id=3807&c=samsung_gt-n7105_galaxy_note_ii_lte_32gb

There is an NDA on the 4g version.
EE has an exclusivity package.

Yep most UK information points to EE having the 4G LTE version.
I hate looking at mobile phone websites the first thing you see is iphone5! Then search for phones coming soon and galaxy note 2 isn't even there!
Samsung needs to get their marketing sorted 4 days to go and nobody knows for sure wtf going on. Carriers are equally to blame for lack of information.

[Q] Which note 3 for these connections

I need a note 3 that can:
connect to AT&T LTE here in the USA
And connect to T-Mobile NL in Holland
And unlocked bootloader
ATT:
850 MHz CLR 5 UMTS/HSPA+ 21Mbit/s 4G In service
1900 MHz PCS 2 UMTS/HSPA+ 21Mbit/s 4G In service
700 MHz Block B 17 LTE 4G In service Main LTE band providing complete coverage
1700/2100 MHz AWS 4 LTE 4G In service Additional LTE band for more bandwidth in select markets
1900 MHz PCS 2 LTE 4G Service starts by the end of 2013 Additional LTE band for more bandwidth in select markets[31]
2300 MHz WCS 30 LTE 4G Approved for deployment in Oct 2012[32]

TMO:
This company uses GSM1800 as their main frequency band for communications. In 2010 T-Mobile Netherlands had some problems with 3G capacity, but after investing in the network modernization they have managed to deal with this problem. So now they provide 3G services using 2100MHz band

Am I restricted to the N900-T? or is there another one you know of.
sorry for the noob question i don't know about all the bands.
Thanks!

T-Mo NL uses the 900Mhz for 2G, 2100Mhz band for 3G, and are in the process of updating to the 900Mhz band for both 2G and 3G. (Should be finished by the end of 2016.) LTE runs on the 1800Mhz band. (I can dream these numbers by now...)
You can find the bands per phone version here: http://forum.xda-developers.com/showthread.php?t=2574886
Does the TMo US version even work with AT&T?
Both N900-t and N9005 work in terms of frequency for 2G.
You will probably not be able to use the N900T for 3G once the network upgrade is finished here, as we're going to be using the 900Mhz as the main frequency for 3G. The N900T can't see that one. The 2100Mhz will be serving as a bandwidth increaser, not as the main band.
There's a chance you won't get 4G everywhere on the N9005 when using it in the US, as it can't see the 700/1700/1900/2300Mhz frequency.
And you're going to have to root to get rid of the region lock either way if you want to use both SIMs.

Tmo version 4G will not work with AT&T 4G. I tried with my wife's phone

T-Mobile (US) devices support the same frequencies as AT&T devices. This is coming from experience and from the fact that I've pretty much memorized all the band numbers that carriers use and phones support.
If you want a Note 3 that supports AT&T LTE in the US and HSPA+ in NL, you can either get the AT&T model or the T-Mobile model. The T-Mobile model supports one extra band (1700 MHz HSPA+) that is only used on T-Mobile US (nowhere outside of North America), so it wouldn't make a difference. Just know that it CAN be used on AT&T. The other differences between the two:
1. The T-Mobile version supports Wifi Calling (if used on T-Mobile), AT&T model doesn't.
2. AT&T removes the "Network Mode" menu from the Settings menu (so you can't force EDGE for example).
3. AT&T version has a locked bootloader. T-Mobile version doesn't.
In many instances, although 900 MHz WCDMA/HSPA+ isn't listed, it's supported. I can't confirm it because I'm in the US, and GSM carriers use (total) 850/1700/1900/2100 MHz for WCDMA, not 900 MHz. I think it's just unlisted to discourage people from exporting the US models. The only LTE frequency that North America shares in common with Europe is 2600 MHz, which is supported by the phone. I believe that's only used in urban areas in Europe.
Overall the T-Mobile model is the most open in terms of bootloader and supported frequencies (though either model would work in your case).

modem hack for Chinese OPO to enable 3G

I thought I might post this in its own thread as it might save people time when they get their Chinese OPOs and notice WCDMA doesn't work..
For all those who don't know, the Chinese OPO does not support WCDMA/FDDLTE in its stock software configuration. You need to swap out the modem to a hacked modem in order to get the feature to work.
I believe the modem attached was pulled from a Find 7, I've tested it, it works. It has been running pretty well for the last week or so but I'll have to test it over the coming weeks to see how reliable it is. They claim 2G/3G but no 4G. 3G/2G works.

For further info (google translate required) :

can you please explain step by step procedure for same?

so your saying that the chinese and world versions of the opo are the same hardware wise and its just a software modem difference?

I have chinese OPO using on T-Mobile in Hungary. 2G/3G/4G are working out of the box, just for you information.

So for three in the UK the Chinese opo might not work at it's best?
Edit: did some research for myself and it will work fine.

As I saw in one of threads on OPO forums it was explained that chinese version do not support only WCDMA band 4.
According to the wiki (UMTS_frequency_bands) this band is used only by following operators:
North America: USA(T-Mobile US, Cincinnati Bell, i wireless), Canada (Eastlink, Mobilicity, Vidéotron, Wind Mobile)
Latin America: Chile(VTR, Nextel), Colombia(TIGO, Movistar), Uruguay(Ancel), Perú(Movistar, Nextel)

The question is can the modem be flashed to support missing WCDMA band 4?

I just flashed the modem on my Chinese OPO and it works flawlessly with China Unicom's 4G service.

Has anyone tried to flash the CM11S factory image and see if that radio activated the bands? The CM11S factory image includes radio images, and I believe is flashed together as a whole.

Yes. Would like to know if the 1700 and 2100 frequency are activated after flashing the modem.

All-
This is the hacked modem for China OPO that supports China Unicom networks.
I have made cwm zip for easiler install as CM would override the modem during OTA upgrades.
This modem comes from the chinese oneplus forum. See link: http://www.oneplusbbs.com/thread-429139-1-1.html
Code:

I have tried other networks with the modem from the ColorOS or CM rom, seems there is no restriction on WCDMA for other networks.

A few things,..
1. I've been lead to believe from various sources that the Intl. and Chinese versions of the OPO are in fact almost identical hardware wise.
see: http://www.gizchina.com/2014/06/12/differences-international-chinese-oneplus-one/
2. I don't have a 4G subscription in China so I cannot confirm whether or not it works with this modem hack.
3. I bought my Chinese OPO from a reseller here in China on Taobao. When I received it I immediately flashed it over to CM11s and subsequently had no 3g (I use WCDMA network China Unicom FYI) for a few days until I found the hacked modem on the Chinese OPO forums. As for those of you who are not in China, I've heard that many Int. resellers will complete this process for you so you won't need to do any flashing yourself, but I can't generalise for all of the sellers out there.
4. I cannot confirm is whether or not this is only some kind of restriction for Chinese wcdma networks (China unicom). I haven't as yet taken my OPO out of this country and tried an international sim card so that is yet to be determined.
ThExSenatoR> I'm curious about your phone configuration perhaps you could post which modem version you use printed from the about screen??
sasalove> are you saying that the Chinese OPO will work outside of China on other wcdma networks but will not work inside China on China Unicom with the stock modems from coloros and CM?
can anybody who uses China unicom on 4g confirm which modem you use and if you also had to flash a different modem in order to access the service?

With some testing, I'm quite confident to conclude the restriction for 3G is on China Unicom only. I got my CMHK and one2free sim to confirm it. I can use 3G and 4G without issue in HK.
I occasionally travel to mainland and I got both China Mobile and China Unicom 3G sim. Only the hacked modem got China Unicom 3G and meanwhile the CM modem cannot connect to the TD-SCDMA for China Mobile.
I'm still waiting for my 4G China Mobile to test TD-LTE...
So in any case, I decide to flash this hacked modem, as it seem to work for all to date...

The modem that come with CM11 should have WCDMA band 4 (1700 MHz) and should also have LTE band 4 (1700 MHz) and band 17 (700b MHz). According to the spec, the difference is supporting TD-SCDMA band 34 (2010-2025 MHz) / TD-LTE for band 39 (1900 MHz) for China. Other than that the spec matches both side.
Therefore, if anyone need band 4 and band 17, they should use the modem that come with CM11 which lack in the Chinese modems.

Thanks mate for clearing that up for me! So it seems that this restriction is only for China Unicom, why might that be I wonder? to my knowledge, It's not like the Chinese OPO's are being sold by China mobile directly...
I'd still like to test out 4G for China Unicom but I would like to find a cheap deal to do it. I can never seem to fully understand the mobile plans in China anybody got any suggestions as to how I might find a plan with a decent amount of data (at least 300mb) for less than 100yuan a month ??

Are we certain that the Chinese OPO has the EXACT SAME hardware as the international OPO sold by One plus?
I remember reading people claiming either side.
Just want to make sure that they indeed have the exact same hardware ie. Radio/modem and just need to have different ROM/modem firmware flashed to enable different bands ie. Band 4 (1700) in my case.

There is a newer hacked modem available. The author states the modem is based on CM12S while supporting all 3G/4G in China. Another user claims to test all of the network modes.

Cheers mate! On another note, can anyone confirm what their wifi/cellular peformance is like with either the original or hacked modems? Since I've pretty much only used the hacked modem (the one I posted at the start of the thread), I can add that performance wise, it's significantly worse than my computer and old iPhone 5 when using the wifi from my bedroom. Where I sit in my bedroom I get consistent full reception on my computer and used to get the same on my iPhone 5, on my OPO I get 1 or 2 bars at most irrespective of whether or not I use 2.4ghz or 5ghz...
Anyone else experience similar?

How do I REALLY add or change LTE bands on my xiaomi redmi 3s?

i have been trying to change the lte bands on my phone for the longest now. i have been following a bunch of tutorials on how to do it but none of them ether hinder nor help mu issue, no matter what i try i dont unlock anymore bands or delete any. i have even tried putting nonsense in the NV section and it dosent remove my current bnads which lead me to believe that for xiaomi phones theirs additional or alternate steps to unlock more bands. has anyone done it before? i need to unlock T-mobile LTE bands
2 (1900 MHz), Band 4 (1700/2100 MHz), Band 12 (700 MHz)

i have been trying to change the lte bands on my phone for the longest now. i have been following a bunch of tutorials on how to do it but none of them ether hinder nor help mu issue, no matter what i try i dont unlock anymore bands or delete any. i have even tried putting nonsense in the NV section and it dosent remove my current bnads which lead me to believe that for xiaomi phones theirs additional or alternate steps to unlock more bands. has anyone done it before? i need to unlock T-mobile LTE bands
2 (1900 MHz), Band 4 (1700/2100 MHz), Band 12 (700 MHz)

i downloaded that before, but i had no idea it was able to change bands i thought it only monitors and tells you what bands your on.

LTE bands depends on your phone hardware
you just can't add any bands
it's hardware dependant i believe

That app doesn't add bands to your device but lets you choose which band do you want to lock among available bands.

Lol, pardon me for misreading the OP
This guide published here should be useful.
It’s not an easy process and there is rooting required, but it will take you through and work for you. You will also need to have your phone rooted before doing it.
All in all, it’s a complex and scary process, and if you’re not used to meddling in your smartphone’s innards, I would recommend staying away from it.
You might end up bricking your phone and losing it altogether.
Also, depending on why you are doing it, some applications of this solution are illegal and might get you in trouble with your carrier.
So just be careful
One more, according to this site, our phone did not even support those frequency which he wanted to work on his phone.
