Is there a way to enable the 1700 MHz band for T-Mobile's 3G network for the i8190? There is (or going to be) a T-Mobile variant of this phone called the Galaxy Exhibit, but I don't know if it uses the same modem. If it does, is there any chance the Galaxy S3 Mini could support T-Mobile's frequencies? From what I understand, I would need to flash the appropriate modem firmware.
Thanks!

No, you'll need to go with a carrier like T-Mobile who support the same frequencies as the international version (I assume, I haven't checked them recently).
T-Mobile has a 2100 MHz band but it's paired with 1700 MHz for AWS so I'm not sure if that would actually work.
The 1900 MHz band would get reception from AT&T, although only in areas where they're using 1900, probably in the city.
That's just for 3G though. If you don't need 3G then T-Mobile and AT&T are both GSM carriers.
you will have 2g coverage with at&t and tmobile, and some 3g with at&t, when you have wcdma 1900 coverage... that's about it
I suck at knowing these radios. But, if you are visiting friends, what you can try to do is borrow their sims from different carriers for 5 minutes and see what works in the area(s) you visit. Just an out of the box thought.
AT&T is using 850/1900MHz 3G/UMTS bands (if i'm not mistaken),
i9000 international version supports 3G/UMTS 900/1900/2100 MHz, 850MHz not included.
so I think you are not able to use the 3G network, but the GSM should be working find although it's much slower.
Yup
That's why us USA folks have to wait for either a USA or Australian Variant of the device.
Thanks a lot for all your replies! I was hoping Samsung would be lazy and build the same radio in all of it's devices. Guess I was wrong. Still, thanks a lot, I'll see how well it works with 2G.
Is there still no way to change the UMTS band on European Galaxies so they work in the US?
Nope. You would have to hardware mod the phone.
They already do on 1900 att and thats that

I know this is an old thread, but I was looking for information about what modems are for what phones and came across it and thought that as an AT&T customer, I should clarify some information.
Most of AT&T 3G network uses 1900 MHz. AT&T is also "overlaying" 850 MHz over their existing 1900 MHz to increase capacity. There may be some 850 MHz only locations, but I am not aware of any. For the most part, if your phone supports UMTS1900, you should be able to get 3G anywhere that AT&T's map shows 3G availability.

if you bought a i9000m from canada. you can use UGKC1 or UGJL2 modem to enable 850
im currently on at&t using i9000m with ZSJPG modem with 850mhz enabled
Just 1900Mhz isn't all that great, kinda slow and spotty. Don't get me wrong, it's usable, but 850 is significantly faster/better at least where I live.
I have an I9000M but occasionally use a modem without 850, and it's not as good.
While there are roundabout ways to get 850 on other modems, I usually use one of the Bell ones like JL2 or KC1.
I am using jl2. kc1 did not work reliably with my microcell and would instead keep trying to pull in weak signal thus sucking battery. As for 850mhz only.. most of the I93 corridor on new England is 850mhz only.

It's not paired. It's a single band that uses 1700 MHz for upload and 2100 MHz for download. Just like the international 2100 Mhz band uses 2100 MHz for download and 1900 MHz for upload.

So just to clarify, my stock i9000m, running 2.3.3 and UGKG3 will get 3G in southern California on both the 850 and 1900 bands? UGKG3 can use both bands?

hey,
i have a GT-I9000, and i'm trying to enable 850mhz band for 3g,
i flashed the jjjv5 modem which is 850enabled,
and selected the 850 band through *#2263#*, the second i select 850 i get no signal, does that mean my phone isn't 850mhz capable or does it mean there is no 850mhz reception in my area ?
galaxy s suports all bands
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 900 / 1900 / 2100
so you dont have 850 band in your area.
perhaps i was not clear - i'm trying to connect to 850mhz WCDMA band, not GPRS/GSM.
where do you live ? do you have the international i9000?
i live in israel, where we have a 850mhz/2100mhz 3g carrier (Pelephone)
the phone was purchased privately, not from the carrier.
i'm not quite sure about the phone version, the box states UMTS bands as 2100,1900,900.
the writing on the box and every document about the phone states GT-I9000.
does that mean that 850 3g band is not possible for me ?
i9000 doesnt support israel's 850 3g band, you can use 2100 instead which is suported by both ,phone and carrier

I'm also having a similar problem. im in Honduras with Tigo paid for 3g but only connecting to edge, i have the gingerbread xwjw5 build. I have a unlocked gt-i9000
only if you have the I9000T you can use the 850 band

well guess ill be replacing this phone lol
keen to swap? im in aus and got a i9000t and would like to stay on Optus :/
Hi everyone,
Im with a huge problema with the Frequency of my UMTS,
When i dial to *#*# 4636 #*#* and get to system information/configurarion
there is an option to select the Band of GMS/UMTS
Automatic
EURO Band
USA Band
JAPAN Band
AUS Band
AUS2 Band
and if i select any of there the phone return Fail when i try to set any on these.
And i think because of that my phone cant connect at 3G and only to EDGE.
Any one knows how to fix that? Maybe a reflash of original rom?
I realize it's an old post...but same here. Anyone else?
@geraldoff
If you're on T-Mobile USA like me, and if your phone doesn't support BOTH 1700 & 2100 MHz, you may only get 2G.

I have the o2x (made in Korea, International version I guess?) and I only had 2G on T-MOBILE USA when I used it.
Hi to everyone!
I wonder whether it's possible in any way to activate such LTE frequencies in our phone as 800, 1800 and 2600 MHz that are commonly used in Europe?
As I understand the phone supports every of them but the frequencies except ATT's 700 and 1700 MHz are not active, e.d. blocked.
Am I right?
So, is there a solution?
Hello,
I searched but didnt find any solution for my n7000,
My n7000 is unlocked but it wont work with AWS tmobile and wind, I read that we have to flash modem or some file to OPEN ENABLE aws band on n7000,
Right now MY n7000 supports
GSM: 850, 900, 1800, 1900 MHz
UMTS: 850, 900, 1900, 2100 MHz
can you please tell me how to enable AWS band ?
I want to use t mobile/wind
Thank you for reading.
no one?
I don't know what AWS band should be, but you cannot change the frequences becouse this is hardware related. Modem is software. I use either Bolt1 or xlt3 modem baseband and all works fine. My last trip to italy I had no problems using wind network.
