help me understand the frequency options

the general thread lists the models and it frequencies, and then list the operators and the used frequencies... but the wikipedia table also has "LTE bands" which are not mentioned anywhere.
what are those about?
Also, i can't see a sinlge model from that wiki table that matches all frequencies on the AT&T/T-Mobile line...
my main goal is to use them on both of those network, which is conveniently on the same line on the general thread , and not have a dead weight when traveling.
i'm sure i'm missing something obvious here, as not even the models market for a certain operator lists all the frequencies listed for that operator...

Its a trade-off no matter what you do.
If you want the most LTE bands, then go with the XT1058 ROGERS variant, which is SIM-Unlocked for any provider. As shown on the wikipedia list, each model number DOES support the bands shown, but certain individual carrier variants may be SIM-locked (AT&T IS - Don't get that one...), or have different 'bloat' software installed.
If you want the most UMTS bands (think HSPA, HSPA+), then go with the XT1053 T-Mobile variant
All the versions support the 4 GSM bands, so calling and 2g data will be consistent no matter which model you get (other than the SIM-Locked variants).
Hope this helps.
PS: LTE band info here: http://niviuk.free.fr/lte_band.php This will show you which frequency corresponds to each band.
EDIT: If you only plan on using AT&T and T-Mobile, DEFINITELY get the T-Mobile variant. It is SIM-unlocked, supports all frequency bands currently deployed in the U.S. by both AT&T -AND- T-Mobile.
If you were to get the Rogers version (or other XT1058), you would completely lose the AWS band which T-Mobile uses extensively. The two additional LTE bands the XT1058 supports over the XT1053 aren't even deployed in the US as of now.

Be careful when looking at the Wikipedia table. It shows the Republic Wireless as supporting some GSM bands that those in the RW thread say it doesn't.. and the link to the FCC doc is really the SPRINT model, not RW. I'm not sure what other issues their might be.
If you want one single phone to use on BOTH att and T-Mo, get the GSM Developer Edition, or the GSM UNlocked (comes with T-Mobile SIM) from Moto Maker.
They support the following bands (per Moto web site, which might not be updated to reflect possible changes in more recent firmwares)...
GSM: 850/900/1800/1900 MHz
UMTS/HSPA: 850/900/ AWS/1900/2100 MHz with HSPA+ up to 42 Mbps (B5/B8/B4/B2/B1)
LTE: 700/AWS/1900MHz (B17/B4/B2)
If you have T-Mobile, the HSPA on AWS is important to get H/H+ in areas T-Mobile hasn't yet refarmed their 1900Mhz spectrum. No other X supports H/H+ on AWS that T-mobile uses.
The GSM Unlocked and Dev Edition will work with ATT's GSM/EDGE/GPRS/HSPA and LTE networks as it supports the necessary bands. There are two extra LTE bands the ATT branded X supports, however they were originally only used outside the USA. Reports are that ATT might start using one of them in the USA, but as of yet you wont notice it with the GSM Unlocked or GSM Dev Edition phones on ATT.
If you are going "non-contract" check the prices. If the Moto Maker and the Developer Edition are the same price, consider the Dev Edition if you want root, as unlocking the bootloader on the Moto Maker and Retail versions voids the warranty, where was unlocking the bootloader on the Dev Edition doesn't. Only difference would be the appearance. You can't customize the look of the Dev Edition, it comes as black face, woven white back, silver accents (buttons and ring around camera). But you can get a case to cover it, or use dbrand skins (I have no affiliation with dbrand, just saw it suggested by others on the forum here, so its worth a shot).

The Republic Wireless and Sprint variants are exactly the same. The both support the 4 GSM bands - wikipedia is correct.
The reason the FCC ID links to the sprint version, is because the RW version *IS THE SAME*
I'm looking at my RW Moto X box, and it lists the SAME FCC ID as the Sprint model....just as wikipedia shows.
The only difference is that the RW version has custom firmware for wifi calling, and unlike Sprint, who -sometimes- allows SIM unlock if you meet their criteria, RW will NEVER OTA-Sim-unlock their phones.
They both are using the same SIM-LOCK trickery, however. If we find an exploit to sim-unlock the Sprint variant, it WILL work on the RW version, enabling the GSM bands.
Was my reply not sufficient? You basically said exactly the same thing I did...

Questions about Nexus 6

As the title says, i need to know since i wont find anything anywhere.
Next month ill be buying the Nexus 6 comming from a note 3
Whats the difference in model number? Eg XT1100, XT1103
International and US version of the phone.
Is there any hardware specific modem changes that i should be aware of before buying it?
Does it matters to me? (Living in Sweden)
Are all custom roms compatible with both model numbers?
Thanks in advance.

International model (XT1100) is made for GSM, as networks in the developed world are all GSM.
N. America model (XT1103) is backwards-compatible with CDMA2000, and also supports some LTE bands unique to the US (Sprint & Verizon, mostly).
Unless noted otherwise by the dev, all the roms here are supported on both models.

So in other words, i want the XT1100 version of the device since im not in the us and Sprint nor Verizon is available here in Sweden.
Thanks! Great info

The 1103 US version has a different radio chip wich supports different LTE bands then the 1100 World (including EU) version.

Custom ROMs work on both models. No hardware changes (SD805 and 3GB RAM on both).
Only the radio hardware is different.
The XT1103 supports CDMA from the stone-age, don't know why the americans (VZW/Sprint) haven't moved on yet.
The XT1100 supports the required LTE bands to be used in Sweden. Most likely the common EU Bands (Band 3/Band 7/Band 20).
The XT1103 supports 3 and 7, but not 20 which is the main LTE band in European countries.

Honor 4x with AT&T connection : Not working in USA

Hi,
I am using honor 4x in India, now I am trying it with AT&T connection in USA.
Phone is not connecting to the AT&T service.
Any specific reason?
Is it locked or it does not support the AT&T range bands?
Thanks.

Probably it doesn't support At&t bands (in the area where you are)

a lot of Huawei phones arent supported on USA bands if im not wrong, an exception is the nexus 6p

may be bands are not supported

Does US Unlocked Phones (Galaxy S8 and Note 8) Support 4G TDD LTE Bands?

I am interested in buying US version (Snapdragon) of factory unlocked Note 8. However, it's full specs on network/radio bands are not listed yet even on Samsung official site.
I looked in full specs for Galaxy S8 unlocked (SM-G950UZKAXAA) vs carrier version such as Galaxy S8 for T-mobile (SM-G950UZKATMB), and noticed that carrier versions all listed support for 4G TDD LTE: B38(2600),B39(1900),B40(2300),B41(2500), while unlocked version does not. As the screenshots show.
So will Note 8 unlocked (Snapdradon) also be missing the 4G TDD LTE bands (B38, B39, B40, B41)?
Or maybe the specs listed on Samsung official site are not accurate and unlocked also supports those bands? Wishful thinking.
4G TDD LTE is used in some countries like China. So anyone with unlocked S8 on tmobile traveled to China can confirm if 4G data worked in China with t-mobile SIM?
If the unlocked phone only has the benefit to switch carriers in US but has limited band support internationally, then I will have to think twice.

Yeah I was trying to figure this out as well. So far, from other sites, I have seen mix messages. One site FrequencyCheck.com states that it does have those bands and other show them is missing...not sure which one is correct. Also, for other sites I have seen that the T-Mobile version also has 3G TD-SCDMA: B34(2010), B39(1880) and the unlocked version has 3G CDMA: 800/1900. I really can not make heads or tails of this information....is it correct, who is wrong??? I called Samsung that they don't have the information yet, so I don't know either way. I'm leaning to go with the Unlocked by Samsung version, but I am in the same boat with regards to this matter.

Looks like it, i have a Unlocked verdion of the phone.

Carrier brand N8 receive all bands after unlocking?

Been going back and forth between purchasing an unlocked N8 or TMO variant N8. Question is, if I bought a TMO variant and then had TMO unlock my phone after meeting their requirements would all the LTE bands then be activated and available on the phone? I've heard that all carrier variants have the hardware for all the bands but are limited to carrier bands when locked.
