how do i get my 3g connection to work?

so i bought a unlocked phone on ebay bout a few months from now. i live in canada, also im in rogers network and everything works fine except my connection. i can only go 2g/edge speed but not 3g!! i have a t-mobile phone unlocked.. anybody know what i can do to get a 3g connection? do i need to install a new image or rom!!!!? please help

You may be out of luck on 3G. To the best of my knowledge, I believe Roger's 3G network runs on the 850 and 1900 MHz bands. However, the G1 runs on T-Mobile's 1700 and 2100 MHz bands. So Edge is the best you'll get (speed-wise).

T-Mobile's rollout of UMTS in the US will focus on the 2100/1700 MHz bands, whereas UMTS coverage in Canada is being provided on the 850 MHz band of the Rogers Wireless network. I think 1900 was added later as well.
My HTC HD is edge (2G only). But I use a lot of WiFi when ever possible.

[Q] Change Galaxy S modem to US Frequencies?

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?

[Q] Is it possible to get the T Mobile 3G network on an AT&T Tilt 2 device?

I purchased a jailbroken AT&T Tilt 2 online but Im using T Mobile service and I was told that I wouldn't be able to access the T Mobile 3g Network with this device. Could someone verify that this true or if not can someone give me some tips on how to set it up on my device.

Its true, because I have a Tilt 2 unlocked to T-Mobile as well. Is there a way to get 3G speeds, I don't know. But honestly, I've never really noticed a difference. But then again, I do stay away from data heavy sites like Youtube and whatnot.

Hmm, interesting question. The main issue is whether the phone has the right bands to connect to the 3G network in question. Its a hardware issue, and either the phone has the right bands built into the chipset or it doesn't. There is no way to change this with software or by changing settings.
T-Mob uses 1700 and 2100 MHz bands, where ATT uses 850 and 1900 MHz bands. HOWEVER, the ATT branded Tilt 2 also has the 2100 MHz band for international use. If your T-Mob service area is on the 2100 MHz bands, its possible (if you area is on 1700 MHz, its not going to work no matter what). In theory, it SHOULD work. I've made many trips to Japan, which uses 2100 MHZ for both voice and data, and my Tilt 2 (and old Tilt before it) has always worked flawlessly on their networks.
But whether it really works or not, I have no idea. Searching around the net yields some posts on other forums asking the same exact question, with conflicting answers (perhaps somebody on here can enlighten?). My gut says, its either its going to work or its not, it shouldn't take any additional setup. Have you tried it yet?
But in short, it was a mistake to buy the ATT branded version. You should have bought the T-Mob branded Touch Pro 2.

Oh, and wrong subforum, BTW. This has nothing to do with ROM development. This should be in the Touch Pro 2, Tilt 2 General forum. But don't cross post there, the mods will probably move this thread over there for you.

The 2100 MHz band you're referring to is different on both companies' devices. For T-Mobile, 2100MHz is the upload frequency. The worldphone AT&T 2100MHz band is a download frequency. 3G requires 2 frequencies to operate in that manner.
The 2100MHz frequency is accompanied by the 1900MHz frequency for uploads. The AT&T Tilt2 has this frequency set to allow both.
As for Japan, I didn't know they were on the 2100MHz band. I've only every seen a couple of companies on 850, 1500, or 1700 MHz. Where were you that you used 2100MHz or which company? I just like to keep up on where the bands are useful when I make trips to Asia.

Ahh, that's right, I think I did read somewhere, that the 1700/2100 MHz bands are used by T-Mob as download/upload. Not like ATT, where which of the 850,1900 MHz band is used for 3G depends on the geographic location/market.
That means the OP is SOL on getting 3G on the Tilt2, right? He would need BOTH the 1700 and 2100 MHz bands on his phone?
Japan uses 2100 MHz exclusively, standardized nationwide, as far as I know. Same with South Korea (although ATT lists that one carrier in S. Korea also uses CDMA 1800, not sure what the deal with that is).
If the 2100 MHz band on the ATT Tilt 2 is just for download, wouldn't this mean that my phone would not be able to connect to the data network in Japan?

Exactly right. It's a hardware problem, not software as some people think. I seem to answer this question at least once a week here. lol The radio chip is different for each model of the Rhodium. That's one of the differences between the several versions.

It depends on what the network is set up as. 3G worldwide requires two bands to operate because of the bandwidth. GPRS and EDGE only require one. If this 2100 MHz frequency is one of the later, then it will work just fine. If this is a 3G band, then it is VERY likely to be paired with the 1900MHz frequency range. That's on GSM, anyway. I'm not 100% sure what CDMA frequencies are their.

European i9000 to work with 3G in Canada??

Yo folks. I am finally flying back to Toronto tomorrow after having been here in Italy for the past 4 years, and I am so pumped up ...
Anyways, I have got an Italian Samsung Galaxy S i9000 with 1900/2100 UMTS bands and the current baseband firmware is I9000XXJVU.
I was wondering if by flashing a Canadian baseband version my SGS perhaps would might give me 3G with Telus or Fido in Canada.
Is that something that could be done via sw or is rather something hardware involved??
Thanks

Do not flash a canadian baseband. There is no way to enable the 850 MHz band in your hardware.
However, in Toronto you will be able to get by by using only the 1900 MHz band. 850 MHz is mostly usefull for rural areas and/or basements.
So to answer your question, yes, it will work.
With Rogers/Fido, you will fall back to EDGE if you are out of the 1900 MHz UMTS coverage.
With Telus/Bell you fill loose signal if you are out of the 1900 MHz UMTS coverage.

[Q] (SOLVED )HTC One M8 HK version - changing UMTS band

I am having HTC One M8 HK edition, S-OFF from Sprint. I have unlocked the SIM few days back and GSM is working fine and I am accessing 2G mobile internet (EDGE) without any issue.
Now my problem is, I am not able to get 3G signal and even I tried in the manual network search mode with no luck. I bought this phone after checking its band support in gsmarena which shows Sprint M8 supports HSDPA 850 / 1900 / 2100. I know in US all UMTS networks have 1900 band and I am in India and here we have only UMTS 2100 band.
Now my questions are:
1. Though the phone supports UMTS 2100 band, I am not able to use it. Is it because Sprint firmware does not have allowed it because its not usable in US?
2. By flashing a different firmware (by changing Model ID) will I be able to access 3G?
3. Is there any way to get 3G on my M8? fed up of 2G speed on high speed mobile
Please help!!!!

Unfortunately, I and others have not been able to connect to 3g even on sprints network. This is because of defective hardware. As much as I tried to get it working, the only fix that worked was a replacement.

No, actually I will be moving to US very soon. Hence, I will go for Sprint after that. But trying T-Mobile/AT&T is good option. I will try over the weekend and let you know. I know there are few who flashed AT&T firmwares for them 3G is working. But they reported few issues with the ROM. If you want to flash T-Mobile you need to flash T-Mobile firmware. For that you need to change the Model ID and of course your device should be S-OFF. Let you know once I try.
But its sad to miss official H/K tweaks as my mobile is HK edition

Thanks for the reply. I checked with other people who are using sprint phones in India and none of them support 3G and later came to know it is a band issue. I also checked with the HTC app which checks whether the phone is defective or not. Read somewhere if its defective HTC replaces with no cost. Here is the app if someone wants to check.
