If LTE bands are dependent on the physical chips that comes with it, doesn't it means that Nexus 5 should technically supports all LTE bands regardless of which region they are sold from? I highly doubt that there's any hardware difference that ships from google US, UK, JP, AU, etc etc. They must have come from the same factory but why the differences in the LTE band supported? Will software hack be able to enable those unsupported LTE bands in the future? Any guess?

what hardware component makes a phone have certain bands? be it 3g or for voice. what makes a phone have at&t bands of 850/900/1800/1900 MHz or at&t 3g bands instead of tmobiles 3g bands? Is it true that there are currently no phones that FULLY work on 2(or more) different networks, including overseas? I know you can get the iphone on tmobile but its not fully capable because you dont have 3g. how far are we from being able to pick our phone then the carrier instead of picking a carrier and then choosing one of their phones?
Also, it seems that at&t's 3g bands are listed as "tri band global" as apposed to tmobiles that only have 2 and are not listed as "global". does that mean that at&t's bands are more capable and may work in areas over seas? wouldnt that mean that at&t has the most advanced cell technology(or at least the most capable) in the country?
no one knows???????????????????????
the crystals inside the cpu often made by qualcomm decide the band supported

that sucks. so its all up to qualcomm(or the maker of the cpu) and the politics if we ever get a fully supported device?
a big whoop for the UK all our carriers use the same bands
Forgive me if this is a trivial question, but since European carriers such as Vodafone and O2 Germany also have the dual-core version of the HOX, is it possible to flash a european radio and use the European LTE frequencies? Or are the frequency bands hard-coded into the chipset?
It was my assumption that the US and European LTE variants used the same hardware components, but were just set up to use different LTE bands.
Frequency support is set in hardware.

Thinking more about this, I'm still not convinced it's impossible to flash a european radio on the HOX to swap LTE bands. Unless the physical antenna is different, I'd think that it's a possibility.
With my other phone, the Samsung Skyrocket, we can flash T-Mobile radios to gain support for the 1700 AWS band. The chipset supports it, and it just took a radio flash to activate it. AFAIK, you can't use 1700 and LTE though - that or a radio with support for both doesn't exist.
I guess it depends on what chipset the German One XL uses..but I'll wait to see if someone has luck before I risk my own One X.
The hardware is different, as I already said.
The Skyrocket (and a few other AT&T phones, like the Galaxy Note) included the AWS band in hardware (likely due to the now defunct merger with T-Mobile that was going on at the time). The hardware was there, but AWS was simply not enabled in software. Hacks to make AWS work on these phones just enabled the software side for what is already supported in hardware. Without the hardware already being there, no amount of radio flashing will create support for frequencies not already there.
Its possible that some bands are "hidden" in the same way that AWS was for the Skyrocket. Lots of folks here on T-Mobile are hoping the same AWS support is possible on our phone. But if the hardware is not already there (such as for different LTE bands, as you are asking for), you can't make it happen by flashing radios. In the case of AWS, AT&T had a reason for including support (T-Mobile merger). They don't have a reason for including support for LTE bands willy-nilly, just for the sake of doing so, without any tangible (monetary) reason.
Hi there
We have a nice discussion here at my work.
We are wondering if a carrier company can modify the LTE bands of some smartphones via software (firmware update, eprom mdification or something like that).
For example, our carrier has the same frequencies for CDMA/3G and LTE as Sprint and U.S. Cellular but different LTE bands.
Our LTE band been the number 2 and SPRINT number 25 (I don't know U.S. Cellular LTE Band).
So if is possible for our carrier to get some of these second hands smartphone and with some permission from someone modify the bands or the bands is something done at SOC/Modem Level?
Hope you understand the question.
Regards
I'm going to buy a North American Nexus 5 and use it in Europe. As far as I know, the LTE frequency bands are different in America and Europe.
My question is, would it be possible to change the radio (or modem? or whatever it's called there) to make the LTE work in Europe? Or is it hardware locked?
No, it's hardware.
Dear all:
As you know, many phones has different sub-type that designed to support different LTE band of varioius geographical regions. As an example, the phone I use has three different variant of dual-SIM phone that differ only in different LTE band supported (Moto X Pure): Chinese variant, Latin America variant, Southeast Asian variant. Aside from different LTE band supported, everything else (hardware wise) is identical.
Can I simply burn Latin American variant ROM (which is also a dual-SIM) to a Chinese phone, assuming that despite differences in LTE band supported, the radio hardware is the same thus the radio*ROM is interchangable.
I hope my question make sense. thanks in advance.
