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.

Hi guys,
My carrier is Digicel in Barbados (Caribbean), i asked what frequencies they used for 3G and 4G on their facebook page and they responded that the frequencies are 900,1800 & 2100.
Which fequencies are used for what? I think 900 & 2100 are 3G but i'm not 100% sure and i'm lost about the 4G frequency.
Thanks for any help.
I believe 3G works on the 900mhz band. Everything is is just EDGE.

en.wikipedia. org/wiki/Digicel#Caribbean_and_Central_American_Operations (remove space in ". org"):
GSM (EDGE (2G)): 900/1800/1900 MHz
UMTS (3G): 1900 MHz
HSDPA (4G) will (almost) definitely use 2100 MHz.
I don't know too much about the specifications behind 4G, but I'm pretty sure it utilizes two bands simultaneously. A few of the bands commonly used for 4G are 850, 1700, 1900, and 2100 MHz, so you'll often see something like HSDPA 850/1900 or 1700/2100. I don't know what Digicel Barbados would be using alongside 2100 MHz.
Well it depends from country to country, because each country uses some frequencies to something (ex. TDT), and mobile phone companies need to reserve the frequencies to use them on their services.
In Portugal, at the moment, LTE uses the 2600 Mhz frequency (Standart for Europe), but when TDT is fully implemented and analog signal is completely turned off, LTE will also use 850 Mhz frequency because it can offer better coverage indoors (comparing to the 2600 Mhz).
In Barbados I have no ideia, but if you know the name of the National Communications Authority (in Portugal it's called ANACOM), search on their website for information about the frequencies used by the mobile operators.

I'll check this out, thanks guys.:good:
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?
My carrier uses SIM for connection and operates on CDMA 800Mhz and CDMA2000 1x-Ev-DO Rev. A 800Mhz. I have GSM operators with 850 / 900 / 1800 / 1900 Mhz and UMTS 2100 Mhz. Now i want a phone with descent battery life and CPU, GPU power that works on both the bands ( CDMA and GSM) 2G and 3G voice and data. Doesn't matter if dual or single sim. Native video call would be preferable. Any suggestion? Pantech? ZTE? xiaomi? Any other brands?
Will this phone work with 3G speeds or only EDGE? Amazon Link.
From what I can gather, Claro frequencies are as follows:
CDMA 1xEV-DO in 800/1900 MHz
GSM/GPRS/EDGE in 850/1900 MHz
UMTS/HSDPA service in the 850 MHz band
This phone shows:
Network Frequency
- 2G: GSM 850/900/1800/1900Mhz
- 3G: WCDMA 850/2100Mhz
It doesn't show anything for UMTS, which a friend is insisting is needed for anything better than EDGE speeds.
Is this true? I am buying as a gift and the current phone the guy is using is capable of 3G speeds there. I wouldn't want to give him something slower, as he uses Whatsapp and stuff like that a lot.
Thanks for any help, I searched for about an hour before I gave up and decided to ask.
