Here's the best I can come up with:
This version (xt1250) is designed to work on Verizons network primarily and lacks band support for many areas. there is a similar model, the xt1225 that is designed for, and sold in Latin America. I don't know about Argentina cellular systems and providers, so I can only guess there. I would find out what the service provider you intend to use implements as a network and what bands are used. (for example, is it a GSM network or CDMA network and what bands do they use? Verizon uses cdma and LTE Band 13, which are missing from the xt1225, but are present on this model. Even though the linked item may say Unlocked or even GSM, it is not equal to the xt1225 for all bands and GSM providers. you really have to check with your carrier to ensure which variant will work for you. I hope this helps.

As the title says I have a Lumia 1320 with a 4g sim which worked fine on my galaxy s4 but on this , when I go into mobile settings it only has the option for 2g or 3g ?
I have flashed the latest UK rom because it came with a Thailand rom on it
Is there a rom I could flash that has the 4g option enabled ?
Are you sure it supports your 4G bands? If you bought it from outside the region (sounds likely) it might not have access to the 4G band(s) that your carrier uses.

So its the hardware ?
I thought if I flashed a Uk rom it would change the radio ?
The phone only physically supports certain radio bands. Re-flashing *might* let you use, say, 1800MHz for LTE (4G) where previously you could only use it for HSDPA (3G), but if your phone doesn't *have* an 1800MHz radio, you're out of luck (and maybe even if it does, depending on how the hardware is configured; i.e. if the radio does the relevant encoding and collision detection and such internally than it will be tied to a specific cellular technology).
Note that I have no idea *what* bands you need... but most mobile operators only have a single LTE band. You should check and see if it's one your phone offers.
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...
Been looking at the radio specs on this ( compared to HTC One) and it seems the GSM/UTS and LTE bands/frequency are all the same except for one of the LTE. The 800Mhz uses band 20 while the HTC One uses band 18. The 1800Mhz and 2600Mhz match.
Would this preclude it from working on Sprint?

Please see this thread:
http://forum.xda-developers.com/ascend-p7/help/verions-p7-t2838058
It shows the different versions of the P7 for use in different countries.
I don't think it will work at all on Sprint, as Sprint is a CDMA network.
Also -- again -- My understanding -- is that the Chinese CDMA (TD-SCDMA) is an entirely and completely different thing (different frequencies, different protocols) than the US Sprint/Verizon CDMA. The P7-L00 would not have 4G at all (and spotty or no 3G) in the US.
For the P7-L10 ("International Version") it would work as follows:
It will work as a basic 2G phone on AT&T or T-Mobile in the US.
It should work on AT&T or T-Mobile 3G in some areas, but since it is only quad band - (No 850MHz band - Not penta band) it may not work in all areas.
4G LTE will not work on AT&T or T-Mobile, or on any provider I know of in the US.
AT&T uses Band 17(700Mhz), Band 5(850Mhz), Band 2(1900Mhz), Band 4(1700/2100Mhz)
T-Mobile uses (apparently) only Band 4(1700/2100Mhz)
The P7-L10 uses LTE: B1/B3/B7/B8/B20
No overlap means no 4G at all.
There is supposed to be a P7-L16 international version that may have different 3G/4G bands, but apparently it has not shipped yet, or at least I do not know where to buy one.
Note, however that it does have WiFi, so as long as you do not mind paying a premium for 4G LTE that will not work at all, you'll have plenty of data connectivity as long as you have WiFi available.
Hope that this helps. This is what I have found in my research, as I would really like to buy one of these phones, but as mentioned, I cannot see paying the price these phones sell for, and then have no 4G at all.
Those in the know, or who have one in the US, please comment/correct.
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.
Based on the specifications, it has GSM bands used by both, however SM-N920R4 is US Cellular CDMA...

Just from looking at the specs for this specific device it appears that it will work on all of T-Mobile's LTE bands but it is missing LTE band 17 support for AT&T. The 2G and 3G bands will work just fine as they match the specs for the N920T/N920A from both carriers. The only thing I am not certain of at this time is if you will have to have the device unlocked to be used with another carrier. Were you using this device on US Cellular or did you just pick this device up recently and want to use it with AT&T or TMO?
Ok thanks, the deal never went through
