I got Nexus S on ATT and I have tried it with a TMobile SIM (got surprised because phone isn't locked...) but it works on 2G only.
I'm wondering if it will work properly (as 3G) in Europe. Does it cover 900 and 2100?
What is ATT's data frequency? Is it 2100?
thanks !
I'm gonna reply to my own topic: according with Wiki ATT uses 850 MHz and 1900 MHz for UMTS (3G) that means ATT (unlocked) phone will work as 2G in Europe (2100 MHz)
On the other hand, T-Mobile's frequencies are 1700 MHz (uplink) and 2100 MHz (downlink).
Does it mean a T-Mobile phone will be able to work properly on Europe's 3G networks (2100 MHz?
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.
Sent from my SGH-T959V using XDA App
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?
Hello guys!
I just brought my Galaxy s2 hd lte which is known as SHV-E120s similar to att galxy s2 skyrocket in ATT.
It is unlock .
when i put my simcard, i always get G which is GPRS. This is so slow and it makes me crazy.
Thus, i look over google and find what my support 3g band which was.
2G Network: GSM 850/ 900 /1800/ 1900
3G Network: HSDPA 850/ 900/ 1900 /2100
HSDPA 900/ 2100
4G Network: LTE 800/ 1800 /2600
Also I look over T-mobile 3G frequency over google and found that
850MHz: GSM/GPRS/EDGE/UMTS/HSPA : 2G/3G
1900 MHz: GSM/GPRS/EDGE: 2G
1700/2100 MHz: UMTS/HSPA/HSPA+: 3G/4G
1900 MHz: UMTS/HSPA/HSPA+: 3g/4G
1700 / 2100 Mhz: LTE
Acoording to this chart. i know that i cannot use LTE.
However, i believe, it will support 3G which i have HSDPA 1900 and 2100 Mhz.
Based on m assumption, because of t mobile use weird signal AWS? thats why my phone does not work 3g?
i really want to solution for it. THE GSRM IS SO SLOW THAT I CANNOT EVEN POSE THINGS ON MY FACEBOOK.....
thank you.

UP !!!
Have exactly the same problem .... any solution to this ????
No it is not similar you're in the wrong subsection. Rocket HD is different. Also make sure your phone is unlocked and u need a different radio compatible with the T-Mobile frequencies
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.
