All the different modifications we can do to our phones is amazing, but is there a way to change the MHz or whatever it is that wont let me get 3G to run on the phone?
I've unlocked my phone to use it on T-Mobile. I'm starting to be annoyed when I need to check something online without wi-fi and it takes
forever.
AT&T - GSM: 850, 900, 1800, 1900 MHz
UMTS: 850, 1900, 2100 MHz
Data: HSDPA 7.2 Mbit/s, UMTS, EDGE
T-Mobile - GSM: 850, 900, 1800, 1900 MHz
UMTS: 850, 1700/2100, 1900, 2100 MHz
Data: HSDPA+ (4G) 42.2 Mbit/s, HSUPA 5.76 Mbit/s, UMTS, EDGE, GPRS
Captivate on t mobile will only get the Edge network because of t mobile frequencies.

That I understand, but I'm wondering if there is a way to change the frequencies.
We can overclock and under volt our devices, so why not adjust the frequencies as well.
Unless that is a hardware thing.

That is the frequency receiver capability.. It isn't hardware... It is like trying to receive fm stations on an am only radio, is that analogy makes any sense
Edit: i meant to say it is hardware not isn't

It's more of a conforming to a hardware standard deal, not so much a greed deal...
Plus, consider this; if all of t-mobile's subscribers were on the same frequency as all of at&t´s, there would need to be a massive increase in the necessary bandwidth to handle the load. That mhz split keeps speeds up and dropped calls down.
Just my thoughts, though.

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.
http://en.wikipedia.org/wiki/UMTS_frequency_bands
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?

Do all the Galaxy S variations have the same modem/phone frequency hardware?
If so, I wondered if I could use Odin to flash the Captivate modem into the Galaxy S I9000 and get the USA phone frequencies working???
I have a Captivate now, but I much prefer the central recessed home button of the I9000. But the I9000 frequencies dont work with Telecom XT in New Zealand. (Captivate does work here)
So... can I just flash with the Captivate Modem into a Galaxy S and get it working in the UMTS 850 Mhz range?
In a nutshell, I just want to get the I9000 to work on the Captivate Mhz bands...
Captivate bands are...
GSM: 850, 900, 1800, 1900
UMTS: 850, 1900, 2100
I9000 bands are...
GSM: 850, 900, 1800, 1900
UMTS: 900, 1900, 2100
(I did do a search but got conflicting answers)
Thanks for your help.

Hmmm... bugger.
I suspected that, but I asked the same question within another thread and was told changing the modem would pork.
Now I must pray to the internet god that they will provided definitive guidance... preferably within this thread
Heaps have tried but its dif hardware, Why else would you get the EXACT same hardware as AT&T/TELSTRA Captivate? They all use 850mhz UTMS. If the phone works for you then great as 850mhz is better then 900mhz due to it being able to go through walls better and other mumble jumbo. Also you can't change the face/lcd as they are dif too. Seems like its a dif phone all round
U can get an I 9000m from Canada... looks like std I 9000 but has bands u want... that is what I did.. there are threads about it search.

The Sprint model can connect to the following frequencies (link):
2G/2.5G - GSM/GPRS/EDGE: 850/900/1800/1900 MHz
3G - UMTS/ HSPA: 1900/2100 MHz with HSPA+ up to 14.4 Mbps
3G - CDMA: 800/1900 MHz for Sprint
4G - LTE: Sprint: 1900 MHz

I'm assuming that when you say "3G," you're referring to HSPA and when you say "GSM," you mean 2G/EDGE. This means that the Sprint model can only connect to the 2100 MHz frequency in your country for 3G. I don't know how it works in your country, but in the US, some carriers only transmit on certain frequencies in some markets (areas). It may be that your carrier is not transmitting 2100 MHz in your area.
For example, in the US, T-Mobile transmits 3G on 1900 and 1700/2100 MHz. However, it doesn't do this everywhere in the country. In some areas, it will transmit 3G on all of those frequencies, but in other areas, it might only transmit on 1900 MHz because it doesn't have the license to transmit on 1700/2100 MHz in that specific area.
Basically, you need to find out if your carrier is actually transmitting 3G on 2100 MHz in your area. What country are you in and what carrier are you using, just out of curiosity?

The Note 3 from AT&T is not capable of supporting those bands. It is not a world phone and it's transceiver is hardwired for AT&T 850 and 1900 bands. AWS is 1700.
Att s3 and s4 can be mod I don't see y the note 3 can be mod as well. Can some one help.

Here are the only frequencies that the Note 3 supports.
GSM:
850, 900, 1800, 1900 MHz
UMTS:
850, 900, 1900, 2100 MHz
If your carrier or the carrier you want to use the phone on does not support these frequencies then it is impossible to use this phone on those carriers.
There is no mod or fix that can make the phone receive and transmit frequencies that it's transceiver is not setup to do. This is a Note 3 and and not a phone from the S series. There have been significant changes in both function as well as security of hardware and limiting user control.

Not true. The S4 and Note 2 for AT&T were just the T-Mobile versions (AWS-enabled) with AWS disabled. If you used QPST to make a modem NV memory backup from a T-Mobile variant and then flashed that back to an AT&T variant, AWS would be enabled
I should know, I did it to my AT&T S4 which I'm using on T-Mobile and if I punch in a dialer code, I can see it connecting to HSPA+ Band 4 (AWS -1700/2100 MHz).
Hi,
I'm a huge galaxy fan since I've had the Galaxy S 4g (T959V) for over two years and it has been through hell but keeps working. I rooted it and loaded custom rom, kernel and modem so I do know a little about smart phones. Now I want to buy a new galaxy, but the s4 apparently is very fragile, so I turned to the S3. I jumped at the chance to buy a 9305 with 2 gb ram and quad core processor, but now I'm not sure that was a good idea, since I have T-Mobile and apparently their bandwidths for 3g and 4g are not compatible with i9305. Is there a way in all this rooting and flashing to change the bandwidths that the i9305 uses?
I9305 Specs:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 2100
4G Network LTE 800 / 1800 / 2600
From TMOBILE:
T-Mobile 4G LTE
T-Mobile’s 4G LTE network uses 1700 MHz and 2100 MHz frequencies. You'll need a phone that supports LTE 1700 MHz and 2100 MHz frequencies.
T-Mobile 4G (HSPA+)
Our 4G network operates on the 1700 MHz and 2100 MHz frequencies. We use 1700 MHz and 2100 MHz frequencies to use voice and data services. You'll need a phone that supports 1700 MHz and 2100 MHz to connect to our 4G network.
Use voice and data services at the same time.
T-Mobile 3G (HSPA)
Our 3G network operates on the 1700 MHz and 2100 MHz frequencies. You'll need a phone that supports 1700 MHz and 2100 MHz to connect to our 3G network.
Use voice and data services simultaneously.
T-Mobile 2G (EDGE)
EDGE, our enhanced 2G service, delivers a theoretical maximum download speed of 236 kbps.
GPRS, our 2G service, delivers a theoretical maximum download speed of 114 kbps. Typical speeds are between 35 kbps and 45 kbps.
Voice and data services cannot work simultaneously when on GPRS or EDGE.
I'm getting a bad feeling that this phone is not going to work well with tmobile 3g/4g without some heavy modification. Any advice welcome!
The bands depend on hardware, so no you won't be able to use the international s3 late version on t mobiles late frequencies but 3g will work as both use 2100
