Hello!
I am having the following problem:
I bought a t mobile g2 unlocked and I am using it here in Brazil, but my carrier supports only 850 mhz.
My doubt is: is there any way to change that?
Can I make this happen?
I ask because I saw that it is possible in other phones since it "has the frequency" but it in not enable.
Thanks

if your phone dosent support the frequency there is no way to change that. look for the tech specs of the desire z.
The G2 is only compatible with the GSM/EDGE frequency of 850 MHz. The UMTS/3G frequency compatibility on the G2 is only 1700/2100 MHz. Its not compatible with UMTS/3G 850 MHz.
You bought the wrong phone for use on your country's 3G network. This is set in hardware, and cannot be changed. This is why you need to fully understand what you are buying, before buying an unlocked device.
Yeah... Thats a shame...
I will se what I can do.
Thanks

You can't do anything except return/sell the G2 and buy a DZ with the proper frequencies for 3G (that would more than likely be the 850/1900 models).
Hi friends, these days buy a samsung nexus I9250 galaxy, but I wanted something:
1. few versions of the galaxy samsung nexus there?
2. There is a version that supports GSM networks lte? which is?
3. i9250 model supports HSPA + 21?
4. i9250 model that handles frequencies in HSPA +?
There are 2 versions.
1) CDMA/LTE on Verizon Wireless USA only. Model i515
2) GSM/HSPA+ (21mbps radio). Pentaband (works on any GSM carrier). Model i9250
And that's it! There are no GSM/LTE models.

As I noted in my post... they all support the same frequencies. Its pentaband GSM it'll work on any GSM network in the world.
For your reference so you can stop asking: http://www.phonearena.com/phones/Samsung-GALAXY-Nexus_id5595
I'm not sure, take expansys for example:
USA:
Network: 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)
UK:
Network: HSPA/WCDMA Europe/Asia: 900/2100 MHz / HSPA+ 21Mbps/HSUPA 5.76Mbps / Quad-band GSM/GPRS/EDGE: 850/900/1800/1900 MHz / (Band frequency, HSPA availability, and data speed are operator dependent)
*Also, on Samsung web SAR page, there:
GT-I9250 GT-I9250J GT-I9250M GT-I9250T
from here:
http://www.samsung.com/sar/sarMain?site_cd=&prd_mdl_name=9250&selNatCd=US&languageCode=EN
So maybe there 4 different variant, also there a SC-04D for Japan,
SHW-M420S and M420K for Korea.
somebody have to check it , also the nexus S have plenty of variants, so I see nothing new here, but just go for standard GT-I9250 as it's pentaband 3G that will work in any country , BTW I dunno if GT-I9250* go with other build thank "yakju", not that it will do anything with the frequencies as it's software, but if you think of it, with other devices there mostly 2 main variants, 1 for Europe, and 1 for Americas, sometime also for China, and other regions. Anyone can get more info about it?

It doesn't matter what variation it is, a GSM phone will work on GSM networks and a LTE phone on all LTE networks. (unlocked, of course)
GSM and LTE have completely different frequencies so a GSM phone will not work on LTE networks and vice versa.
PS. HSDPA+ has nothing to do with the phone itself but if the network you are on provides you with it.

Its all just semantics and slightly different radio software. They are all the same. You can use ANY i9250 model on ANY GSM carrier in the world. Read my first post it gives you all the information you need in practicality.
The i9250 is regularly for sale from dozens of resellers. Just buy one ffs.
What did you mean by Its all just semantics and slightly different radio software?
you mean it's possible to disable some of the frequencies with flashing different radio? from what I learned here, software have nothing to do with the frequencies that device supports, only hardware (antennas) matters here. also the other variants, are made for specific operators, so a normal i9520 wins, as you not depend on Samsung or the operator for OTA updates, also I'm not sure if let say J variant get OTA with "yakju".

Not hardware radio, software radio. The different variants (yakju** models) have slightly different radio software for the regions they're originally sold in. All i9250 models support the same GSM frequencies.
These models aren't necessarily made for specific carriers but specific regions. Any i9250 can be flashed to yakju with images from Google if you prefer. You will receive OTAs either way, but may receive them slightly faster if you choose to flash to yakju.
Long story short, you shouldn't care. Just buy the cheapest one you can get, because if it doesn't come with yakju out of the box, it takes about ~5minutes to flash it to yakju and be the exact same (and no this doesn't require root or anything, you just unlock your bootloader and flash images, then it is completely stock).
So just to drive it home again: ANY i9250 you buy will work on ANY carrier in the world. The hardware is the same, and the software may be slightly different, but 100% changeable to your liking. Just buy the phone.
Ok, and I guess, lock the bootloader after?
I also buy it soon, and I also want to use "yakju" build, but dont want to root or unlock bootloader, but there is no way to flash "yakju" without unlock the bootloader?
*sigh*
Jesus christ what happened to the experimental Nexus spirit?
Why on earth even get this phone if you are afraid of touching it?
It's a phone designed to be ****ed with and still be bootable with code hosted outside it if you **** it up completely. It's virtually impossible to break.
How on earth can you even consider buying this phone if your main intention is not using what is what made for?
If you don't want all that, just get a regular phone, made for regular people, where you get your updates, regularly, through some really ****ty 3rd party "value-addon" software. Which only runs on 2 versions of Windows. And slowly.
Or just get your yakju/non-yakju phone and get the updates when you do, which will still be before everyone else.
Really.
You are putting to much into this. Either you want a moddable phone, and this one is it, or you are not a modder, and you should get something else.

That's quite a pompous rant. Shame you're so embarrassingly off the mark. The Nexus is a dev phone, because it is important to have a smoothly running device with the latest operating system out there for manufacturers and app developers. It contributes to the viability of the Android ecosystem (#1 reason the Nexus is made for). Hence the rapid OTA system on an incremental version basis. But you're full blown ego-crazy if you think Google released a phone just for you - the 0.001% that wants to mod. This is a mass market phone now (#2 reason it is made for). Most consumers buy it exactly so they don't have to root and install custom roms to stay up to date without the inherent bleeding-edge bugs that goes along with hacking. All Android phones are moddable. Why the hell wouldn't you have bought something with better specs if you were just going to mod it? You did it wrong. Sorry to break it to you, but Google made the GN without your specific hobby in mind.

You don't root. You do unlock the bootloader, but who cares! If you must have a locked bootloader, its just 1 extra command line entry to lock it again after you're done flashing to yakju.
Don't think you're understanding really. Unlocking the bootloader on a Nexus is not a big deal. It is literally 1 command line entry to unlock or lock. Like I said, flashing yakju takes literally 5 minutes.
I know that, but people here talking about the variants of it,
how can we be 100% sure, that for example M and J have the same hardware?
and only the radio software is different?!

You just know! Stop worrying FFS. I could hand you either one with flashed yakju firmware and you would never be able to tell the difference (even with regional software you wouldn't tell). No matter what, you'll get an i9250 that's what matters.

So I heard LTE is backwards compatible with GSM and HSDPA + My carrier supports AWS band 4. Will this work? Has anyone tried it?
So you're basically asking if the AT&T Optimus G will work with T-mobile's 4G Network, right? The answer is NO. Or at least not by default. That's because, even though the phone has the correct band (1700/2100), you would still need the correct radio to be able to use that specific frequency (again 1700/2100) with your carrier. Much like the AT&T Galaxy Note I717. It supports the 1700 frequency, but in order to have that working band with Tmobile, we had to flash a Tmobile specific baseband/radio from the Galaxy s2, Galaxy S Blaze 4G and/or Tmobile Galaxy Note to be able to use the phone on the 1700 freq. So in this case, Unfortunately, Tmobile won't be releasing the LG Optimus G, so there won't be any radios available to use. But, the LG NExus 4 actually has the exact hardware specs or SOC as the LG Optimus G, so a radio/baseband port might be possible.
I hope this post made sense to you.
So what is the difference than taking a locked phone, unlocking it to another network that shares the same GSM frequency?

Actually the two networks don't share the same GSM freq. Yes the AT&T LG Optimus G does have the AWS 1700 band in the hardware, but it is not enabled by default in the software. In order to enable the AWS 1700 freq, you'll need to use/flash the correct radio that carries the AWS 1700 freq. Like i said in the earlier post, one might be able to possibly port the a radio/baseband from the LG Nexus 4. Since it supports all pentaband frequencies.
So why would they disable it if the carrier uses 1700/2100 for LTE? I'm still not understanding its limitation
The carrier I want to bring it to uses AWS 1700/2100 3.5G.
Are they selling a phone that doesn't work with LTE on there network? Or can the phone only do 1700/2100 in LTE ?

It's not that the 1700/2100 bands are disabled. They are very much enabled but the radio is set to use them for LTE.
So you are saying even though LTE is backward compatible the band installed is software limiting the hardware to only allow LTE 1700/2100?
Nuxtux said:

LTE phones are backwards compatible because they support other bands for HSPA and GSM. For example, a carrier using 1700 MHz for LTE may use 850 and 1900 for HSPA but the 1700 will only work with LTE.

You somewhat got it. It is the same problem with AT&T's HTC ONE X. The phone as the 1700 band for LTE, but when used with Tmo it only picks up 2G using the 1900 GSM. But with Tmo merging with Metro PCS, and partnering with Ericsson and Nokia Siemens Network, the H+ 1900 Spectrum will be available everywhere very soon. I read an article on tmonews.com that it should be done by the end of this year.
maybe the Canadian Telus version would work with T-Mo's AWS

Hi there, I've been itching to get this phone for a while and I was wondering if LTE would work on the phone if i were to unlock it and use it on the Telus network here in Canada.... I've looked up the stats and all but all i see is that Telus only supports the 700 mhz frequency while I see that AT&T has both 700 and 1700. So would the phone only support one frequency or both? Sorry if this has been asked already....
I know I'm late to the party, and digging up old threads is frowned apon, and SkyeBTCH you probably already decided to get, or not to get the phone, but we can not let even 1 person go unhelped, lol. Any who, I have this AT&T phone unlocked running on Telus, and it definitely does LTE, 4G, & 4G LTE, so pick your poison, and get this phone it is an absolute beast, grrrrr I would rather have this phone over the Sammy S series, Note series, and pretty much every other phone out in the wild right now; real talk...

Here may be another stupid question, But Not even Samsung them selfs on the USA Department couldnt answer this, So let me explain a few things before I ask, so that you may understand what I may be talking about..
I have 2 Samsung galaxy S Tab's 10.5
One is 32gb Wifi Bought from Best Buy (T800)
The other is 16gb Wifi LTE International (T805) Unlocked.
From what I understand the International version will not support 4G on T-Mobile or most any carrier in USA do to the supported Signal.
What I want to know is, Whats the diffrents between the International and the Local USA version when it comes to the LTE. I cant find anything that tells me what I want to know.
From what I can see, is the signals ranges are the same as the USA version. but maybe I am reading it wrong,
When I check out the hardware with diffrent apps that support that. it pretty much shows the two being the same except for a few things that dont seem to matter.
So to make a long story short,, I just want to know what the diffrents is between the LTE Local USA and the LTE International version.

1. I believe the USA specific versions are voice crippled so you cannot make voice calls.
2. According to here
http://en.wikipedia.org/wiki/T-Mobile_US#Radio_frequency_spectrum_chart
The frequencies supported by T-Mob USA for LTE are....
1700/2100 MHz LTE 4G In Service/Building out Covers 250 million POPs as of October, 2014
700 MHz Block A LTE 4G A-block rollout has begun, and several devices already support this frequency.
1900 MHz PCS LTE 4G In Service/Building out Primarily used for a quick rollout of rural LTE as sites contain a pre-existing GSM antenna
3. According to here
http://en.wikipedia.org/wiki/Samsung_Galaxy_Tab_S_10.5
The frequencies supported by the International 10.5 Tab S are
800/850/900/1800/2100/2600
As you can see the only 'common' frequency is the 2100 Mhz set which 'should' cover the bulk of Urban USA however there may be specific signalling that T-Mob require to allow devices to access that frequency.
Hope this helps

I want to thank you very much. I really did search around to try and understand. but when it comes to the carrier LTE stuff, I no nothing about it.
Yea T-Mobile told me the only plan they have for tablets are Data and no voice. that really sucks. I dont understand that one. I have an
LG G3 that has T-Mobile. I can use the hotspot on that if needed.. the chances that im going to leave my house with this Tablet are very slim. so I can just stay with the wifi.
