Please help!! I got a SHW-M250K and I can't connect to AT&T 3G (HSPA/UMTS) at all. I'm also having trouble connecting to usually GSM network (the signal is usually weak. Sometimes it just got disconnected)
Is this normal??? I've searched the forum and it appears that M250K only have 910 and 2100 MHz HSPA radio? If that is true, there's no hope for my M250K to connect to AT&T's 850 and 1900 MHz 3G network??
I'm really depressed now. Please kindly help!

The Korean version is useless in the US, as far as I know.
See here
http://forum.xda-developers.com/showpost.php?p=13490996&postcount=3
It only has UMTS 2100. ATT uses 850/1900 for 3g.
The Korean version also uses different SMS/MMS so you won't be able to use that either.

I've seen this blog.

However, with our experience in the industry we have seen that almost every device launched in recent years within Europe has been ‘optimised’, with the American 850/1900 range locked down, leaving only 900/2100 for the rest of the world. As we are based in the UK it is for this reason we have taken the tentative step of advertising only these frequencies.

yeah, UK clove store said EU galaxy S2 doesn't support US 850/1900
network. (They said that may be US 850/1900 UMTS frequencies are locked.)
But, I find google news.
http://www.mydaily-gadget.com/news/5718-att-getting-samsung-galaxy-s2-gt-i9100-fcc-says-i-do
Speaking about release dates we do not have a specific one for the GT-i9100 in the USA but we can confirm the FFC has authorized the use of this particular smart phone on the 850MHz and 1900MHz GSM frequencies which means the first carrier to offer the Samsung Galaxy S II might be AT&T. These two frequencies account for the AT&T 3G network but they also match some Canada operator’s frequencies so there is a big chance the Galaxy S II will land there too in the near future.

That first link (that I provided earlier tonight I think) - read it to the end please, Clove has all the info on that page, just finish reading it. sorry for the tone , but I think you did not pay enough attention - there are comments to that blog post that say clove confirmed with the manufacturer and local distributor that all 4 bands are present.
I'm confused here
I have SGSII ordered from Clove. I plan to use it with ATT sim card. Have I made a mistake? Will I be able to use it? Do I need to cancel?
I hope it works well with AT&T since I intend to get this phone.
My current (imported) GT-i9000 did not properly support AT&T and has very poor call quality and call drop issues.

Although Clove originally said they doubted it would support 850/1900 3G+, they did later confirm their stock would be quad-band 3G. So no need to worry about support for NAM 3G.
Once someone get's the GS2 in USA on ATT, can you confirm that it indeed works on Edge AND 3G?

That's because the i9000 is only tri-band UMTS and only supports AT&T's 1900 frequency. When it gets to an area where the 1900 H/3G signal is weak, it can't switch over to the 850 UMTS simply because its hardware doesn't support it. So, then the phone call drops. You'll notice if you switch the i9000 to 2G/Edge, you'll never get a dropped call... because it's quad band GSM.
Also, ever notice you never get dropped calls when stationary and on H/3G? That's because with a solid 1900 UMTS signal, the i9000 will never search for the unsupported 850 band.
(And yes, I have confirmed all of this as I also own an i9000.)
i9100 supports quad-band UMTS with 850/1900 H/3G, so you will not have the frequent dropped calls anymore.
Here are the frequencies for AT&T: http://en.wikipedia.org/wiki/AT&T_Mobility#Radio_Frequency_Summary
Frequencies used on the AT&T Network
850 MHz GSM/GPRS/EDGE 2G
1900 MHz GSM/GPRS/EDGE 2G
850 MHz UMTS/HSPA 3G
1900 MHz UMTS/HSPA 3G
700 MHz LTE 4G
So, the i9100 International will do almost all. Except LTE.

Thanks for your information.
Hi guys,
I am using 77.30P radio in Brazil and having problems with the signal, the carriers here are a mess, the same carrier uses from 850mhz to 2100mhz...
My question is, what basebandd (radio) can i flash which uses all those frequencies?
If someone can help me out by pointing the know frequencies for the most common radios available it would be of great help!
Thanks in advance
All AT&T radios can use UMTS (3G) 850 and 2100 if I recall correctly.

Do you know where can i find that information for sure?
If this issue is not related to baseband, i have to start looking somewhere else...

Google what bands does AT&T use for 3G. But as I said, I think it's 850 and 2100.
AT&T uses the 850 and 1900 bands for 3G. As for the radio version, use the one that came with your phone. The atrix supports W-CDMA 850/1900/2100 for the AT&T version but mine in addition to those listed above, supports the 900 band as printed on the box.

yeah but it's posible that works men because i really want to know, without signal its a useless phone, and i want to have 3g data unlimited like they offer and i really love this phone
thats why i put t-mobile frecuency so you can see if it is possible
According to Wikipedia, T-Mobile uses 1700 MHz and 1900 MHz for UMTS, the S5830L uses 850 / 1900 MHz for UMTS/3G/HSDPA, so in theory it should work.
What is the rom that you're using?

Only the modem, but that is a one package file. Can you give a few minutes, I'll make a tar with the modem only.

No problem, if it doesn't work, I have another idea.
As I was saying to another user with the same problem, I found that Galaxy Ace doesn't work with T-Mobile 3G, only with AT&T 3G, I got this from Wikipedia:
AT&T GSM/3G 850/1900mhz
T-Mobile USA GSM 1900mhz 3G 1700mhz 4G (only) 1900mhz
http://pt.wikipedia.org/wiki/Anexo:Lista_de_operadores_GSM#EUA
Galaxy Ace can work with all these frequencies except 1700:
http://www.gsmarena.com/samsung_galaxy_ace_s5830-3724.php
It will work only on 2G with T-Mobile.

that's why i make another thread because i read that it's not possible to make it work on T-mobile, but you tell me that it was possible; i read to that it wasn't possible on ATT but acording to th frecuency it was possible, thank you for your help know i don't think to make it work here so i'm going to sent the phone to mexico because ATT its to expensive, Now i need a new phone tell me which one do you think its better Sony ericcson Xperia Mini Pro (the second one the one with bravia screen) or the Sony Xperia Sola (doen't come out yet).
can you change the freqencies the ace can work with by flashing the modem or somethin

It'll probably work but I don't think o2 supports the 3g bands our phone uses so you'll be running on edge
Sent from my SGH-I777 using Tapatalk 2 Beta-5
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.
Hello everyone,
I am thinking to purchase at&t or T-mobile samsung galaxy S3, samsung galaxy s3 mini, iphone 4, 4s or 5 immediately before I go back to my homeland. I know these samsung galaxy S3 and iphone support HSDPA network. My homeland has only WCDMA 2100MHz network. My question is will these galaxy S3 or iphone works on WCDMA 2100 Mhz network. Thanks in advance.
HSDPA is the data connection protocol for 3G networks. WCDMA is what 3G is called, and 2100 MHz is the frequency. You need to look at a full specification list for the carrier variant of the phone you want, and check that it supports 2100 MHz frequency band. You'll see this info and supported 2G and 3G bands right at the top of the specification list in GSMarena. If the phone supports 2100 MHz, then it will work in your country. HSDPA/HSUPA is to WCDMA as GPRS/EDGE is to 2G GSM networks. They are just data protocols. You need to look at the bandwidth specifications.
