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.

Go to Start>Settings>Phone>More.
First one should be band selection. Highlight it and press Get settings.
You will be able to select the frequency band.
- Automatic
- GSM 900 / 1800
- GSM 1900
- WCDMA
Select either GSM 900 / 1800 OR GSM 1900 depending on your network carrier.
Last, RTFM.
thx !!
I'm going to buy i780 and just want to make sure I can log into 2G band, 'cos the signal of local 3G provider is really suxk. And FYI, I RTFM already, but it never mentioning the band locking/choosing.....
what is the phone bands in 2g network and what in 3g network ?
thanks !!
I believe these are accurate.
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 900 / 1700 / 2100
You will be able to get 3G on T-Mobile in the US and on European networks, but it will not work on other North American carriers like AT&T, Rogers, Telus, etc. On those networks, you will get standard GSM/EDGE (2G) service.
it has 2100 in 3g for sure ?

Yep. Check out the product specs from the HTC website. Scroll down to the bottom of the page to the section titled Network.

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?
