Hi! I've bought this phone (SGH-T959V) from T-Mobile on USA, and when I went to Argentina, I found that the carrier that I have (Movistar) mixes the frequencies or something like that.
It uses GSM 850 / 1900 and UMTS 850 / 1900. By default, my phone can't use 3g (neither HSDPA) from this carrier.
Dialing *#*#197328640#*#* And going to Network Control > Band Selection, I can choose which frequencies to enable / disable.
If I disable GSM 850, and enable all the rest, I can get to use 3g on the 1900 Mhz, but I get much lower signal.
The frequencies that I can enable / disable from this menu are:
GSM 850
GSM 900
FCS 1800
PCS 1900
WCDMA 2100
WCDMA 1700
WCDMA 1900
I don't know how this works, I want to use my phone and be able to use 3g / HSDPA / HSDPA+ / 4g if possible..
I think that I need to find a way to enable WCDMA 850 on my phone.. Is it possible?
I am using the last upgrade from Kies (Gingerbread) 2.3.6
Do I have to flash a new modem? I've searched for available modems for this phone, but none of them say anything about enabling WCDMA 850 frequency
When I go into Settings - Wireless and network - Mobile networks - Network mode it has a GSM/WCDMA (auto mode)
Have you tried that?
Yes, I've tried that, that option is enabled!
In the GL9003L model (Samsung Galaxy S too) from this country, the WCDMA 850 option is enable (also the WCDMA900). Isn't there a way to add that frequency to my phone >.< ?
The hardware doesn't support UMTS 850 which you said is used by your carrier's 4G. You won't be able to use this phone on their 4G network.
Buh, so there's no way to change the frequencies it uses?
Sucks I can't use 3g (not 4g, 3g!!!) on my country
No you won't be able to. According to this page, these are the frequencies available on the phone:

2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 1700 / 2100

Your network will have to be running on exactly those frequenices to get 3G/4G
I think that is wrong.. I have another carrier that works on the 850 / 1900 band and I CAN user their 3g (mostly because I can connect to the 1900 band..), but I can't use HSDPA+.
So:
with one carrier, Movistar, that uses UMTS 850 / 1900 I can't use 3g, it only connects to the EDGE network, and when I dial *#0011# with the GSM bands disabled it says that the 3g service is limited and I can't use it at all.
With the other carrier, Personal, that uses the same bands, I can use 3g on the 1900 band, but can't use HSDPA or the 850 band.
Also, from the #*#*193728640#*#* menu I can choose the UMTS 1900 band.
I've a similar problem the difference is a got 3G but not 4G and can't figure out what is going on. I'm with digicel and the only use 1900 wich is already enabled. I once tried movistar and had the same problem I suggest you another carrier
This's my problem:

Do not trust phonearena as it has wrong information about our device frequencies that it can use.
umts 1700,2100,1900
So basically no, you won't get anything else than edge on those 850/900 frequencies.

I have a question about 3g frequencies among all carriers. If I have a device for example which supports these Frequencies
Device:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 1900 / 2100
And say I wanna use this device on T-mobile
T-Mobile USA 850/1900 for 2G/EDGE - 1700/1900 3G/HSPA
And I am only receiving EDGE on T-mobiles network is this because I am missing the 1700 frequency on my device? For all carriers listed 3g frequencies must the phone your using have both those frequencies to be able to get a 3g signal?
I'm thinking of buying a Note 10.1 and am in two minds whether to go for the 3G or just wifi version as I may be moving to the US in the next 4-5 months. Will the international 3G version work on T-Mobile or other US carrier in full HSPA+ speed?
OK, I found that Tmobile is moving it's HSPA network to a new frequency to be more compatible with the other networks.
4G/LTE upgrade
On February 23, 2012, during the Q4 Earnings Call, the future of the T-Mobile 4G upgrade path was laid out. T-Mobile's LTE network will be rolled out on the AWS spectrum, and their HSPA+ network will transition to the PCS band, in order to achieve compatibility with other networks and phones in the USA, T-Mobile plans to begin this transition in early 2013.[41]

1900 MHz UMTS/HSPA/HSPA+ 3G/4G - According to reports from users, T-Mobile started to reapportion its PCS frequency (UMTS frequency band II) for UMTS service in some areas. Will be expanded during LTE upgrade.[44]

And from Samsung the Note 10.1 has the following radio spectrums
Platform
850 / 900 / 1800 / 1900MHz GSM&EDGE Band
850 / 900 / 1900 / 2100MHz 3G Band
GPRS Network&Data: 850 / 900 / 1800 / 1900
EDGE Network&Data: 850 / 900 / 1800 / 1900

So I assume that once Tmobile has finished their transition then the Note 10.1 will be able to get HSPA+ speeds over 3G or am I missing something?
I have an opportunity for a really good priced P6800. The seller does not know which carrier it is...? Here is what I was told:
These are the networks that the tab will work with.
GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 1900 / 2100
Please let me know.
Much appreciated!

Any GSM/HSPA network, which means about 99.99% of all networks in the world. Since you live in the USA, it means AT&T and T-Mobile (on most areas, in some places T-Mobile still didn't move their 3G band to the international standard frequency of 2.1GHz).
Will this phone or a variant of work on T Mobile or Metro PCS? I noticed there appeared to be some spectrums missing when I look at the specs, but I am not sure if they were older spectrums that are going to be phased out slowly. Any help would be appreciated. I'm also open to suggestions on other 5.9 inch phones that would work better on T Mobile / Metro PCS.
I have a D838 this have:
GSM / HSPA / LTE
2G bands GSM 900 / 1800 / 1900
3G bands HSDPA 900 / 2100
4G bands LTE 1800 / 2600 (Bands 3, 7)
