I bought my samsung galaxy s 4g from t-mobile in the U.S.
I just came to mexico and unlocked the phone so i could use mexico´s cellphone network: telcel.
I already can make calls and receive messages but for some reason i can´t use telcel´s 3g network nor send or receive multimedia messages.
i need some help on how to set up my cellphone so i can conect to the telcel´s 3g network.
Hey I'm sorry I can't answer your Q but how did you unlock to work on telcel? Please and thank you

Dumb question but you have a telcel sim with a data plan right?
What bands does there network use?
i took it to a store when they unlock almost any cellphone, but they just let you use any sim card to call or receive text and that´s it.

and t-mobile 3G network supports both the 1700MHz and 2100MHz frequencies.

Hello All,
I am having issues connecting to the 3G network of Vodafone in India. My SGS2 is from AT&T and I was able to root it & unlock it and its works fine with the call and other stuff. I flashed the UnNamed v1.0.4 ROM and its been pretty stable.
But after activating my 3G service here, all I see is E with the 2 arrows. I researched online and saw that we need to change the CSC code. I looked up at the CSC code on my phone by dialing in *#272*<your IMEI># and its shows as ATT.
Can you please help me on how to change the CSC to INU (India Localisation) so that I can access the 3G network here.
Thanks

you probably just need to add your apn. Flash http://forum.xda-developers.com/showthread.php?t=1299705 its based on the international version so it might let you select your network.
First, make sure that Vodafone in India works in UMTS 850/1900/2100mhz bands. If they are using 900mhz band, this phone does not support it. As much as I know most European and Asian countries use either 900mhz or 2100mhz or both.
It could be frequency or any other issue but if you are looking to change your CSC then look up app "Samsung Galaxy S / S2 CSC" in the market and give it a try. Remember that your ROM has to support MultiCSC.
EDGE with data functioning is a clear sign of a band mismatch, not an APN issue.

India is 2100mhz while the at&t sgsii is 850/1900 so 3g won't work. The t-mobile sgsii would work though, t-mobile's 3g frequency is 1700/2100.

AT&T GS2 supports 850/1900/2100 3G bands. So, if the paticular carrier uses 900 for 3G, it won't work.
Or if it happens to use the 1700 MHz AWS band - but I don't know if any Indian carriers do.

1700 seems to be North America exclusive Rest of the world primarily use 900 and 2100 for 3G with Brazil and Austrialia also use 850 and 1900 in addition to 900 and 2100.
Hi folks
I just moved to the US (about a week ago) and was wondering why my mobile internet connection is so slow.
I have a SGS2 factory unlocked and i was fine with it in Germany (no problems with 2g or 3g speed)
Now I'm in the US with a t-mobile prepaid card which should give me 3g speeds , if not 3g at least EDGE Speed. But the only thing i get is the E-sign with 2 arrows which is friggin slow.
As far as i know t-mobile's 2g & 3g frequencies should be the same as in Europe.
So my question: Is my phone the problem or is it just that the 2g/3g coverage in San Diego is so bad ?
thx in advance
its normal...coz sgs2 does not support t-mobile 3g bands....but it does support at&t 3g bands....i am also using t-mobile prepaid plan...and dont use data that much...coz everywhere i go i have wifi....

Asking who directly? T-Mobile USA? You can ask, won't change the answer. If you want 3/4g in the US with either a European Galaxy S2 (GT-I9100) or an unlocked iPhone, you will need to be on AT&T.
T-Mobile doesn't use the frequencies that those two phones support.

USA uses different bands from the rest of the world because, well, idk
North America:
GSM: 850/900/1800/1900 MHz
CDMA: Band Class: 0/1/10
WCDMA: Bands: 1/2/4/5/6/8/19
LTE: Bands: 1/2/4/5/17/19/25/26/41
Rest of World:
GSM: 850/900/1800/1900 MHz
WCDMA: Bands: 1/2/4/5/6/8
LTE: Bands: 1/3/5/7/8/20
This might be the case here, i don't think its carriers fault but idk really.
Hey guys, just about to trade and get one of these, I just want to know if it can work in the UK because At&t is USA based. Will my O2 sim work in it by using the app from the market which carrier unlocks it?
No comments about my username please

It'll probably work but I don't think o2 supports the 3g bands our phone uses so you'll be running on edge

thanks,
I searched up o2's 3g bands and it came up with, 850,900 and 1800.
The samsung galaxy s2 i777 model bands: Quad-Band 850/900/1800/1900 MHz, 3G EURO/AT&T AND 3G Network HSDPA 850 / 1900 / 2100
So it could possibly work. I don't use 3G much anyway, I only get 2g in my area and at school I get HSDPA. Might ask the trader if i can trial the:
a) sim
b) network connection bands

Just might have to make sure you are not in a 1900 mhz band area

Just FYI, only ONE of the frequencies need to match for you to get 3G, they don't send out one frequency at a time.
Can I unlock an i9100 to USA Tmobile services? Do I need to install a custom room to make it work with Tmobile?
I look everywhere and can't find the answer. I only see different countries rom but no USA rom.
If the i9100 is unlock, shouldn't I just put a sim card and it connects to Tmobile? I did that, it didn't ask for any unlock code and doesn't connect to Tmobile.

As far as i know it will not work for Tmobile's network because they uses a 1700 MHz band frequency for 3G. The i9100 doesn't support this band
You can try unlocking your device and try? but i think you'll only be able to just make phone calls and with the internet your gonna end up getting EDGE speeds which is really slow.
If you had the chance to trade your i9100 for the Tmobiles variant i'd do it or sell that one you got and get the TMobiles version?

Yes, you can use it on t-mobile. However, depending on the area you live in, you may not get a 3G signal. You may only get EDGE speeds. T-Mobile primarily uses the 1700 mhz band for its 3G signal. They are however beginning to refarm some old 1900 mhz bands that currently are used for 2G data/voice and are converting it to 3G HSPA data. Check airportal.de to see if your area will have T-Mobile 1900 mhz HSPA coverage. Hope this helps.

There's nothing to unlock in an international version. It's already unlocked.

I have similar question, I'm going to US in the next month, I have i9100 and I'm wondering what mobile network will be the best for internet to me? Is there some network with similar bands as in Europe?
Hi,
Recently I happen to move to India from USA. I had Samsung Galaxy S3 - SGH i747 purchased in in US, which was under 2 year contract. I tried to call AT&T guys to give me unlock code but they didn't give me since my contract was not over.
I moved to India and tried to unlock my phone from local shop. I am able to make/receive calls now having these issues.
1. 3G is not working . When I see different available bands in my phone using *#2263#, it shows WCDMA 850, 900, 1700, 1900 and WCDMS IMT2000 under WCDMA band preferences. I am using Vodafone in India which runs on UMTS 2100. I visited Vodafone store couple of times but they are not able to help me. How do I get 2100 frequency in my phone ?
2. Currently I have set preference to run my phone on GSM Band so 2G is working. There are certain areas in my city where Vodafone 2G is also not working. In those areas, I don't receive any call even though I have very good network coverage. I tried switching off my mobile network in case I can receive calls but its of no help.
Request for your to resolve this. I am fed up with this nice working phone and need to purchase new one if these issues don't get resolved.
Thanks
