Hi,
The story is here:
I owned a korean version i9100 (M250K) and flash it with the latest CM10 nightly version (20120908, band version I9100XXLPW). It works well with my current carrier, which operate at 2100mhz frequency.
I will travel to US next weeks and plan to purchase T-mobile pay by days data plan, but because T-mobile US operate in a confusing 1700/2100mhz frequency, I am curious to know whether my 9100 can run in 4G speed or only 2G(GPRS) supported.
So my questions are:
1. is there any code to check current supported frequency band in my 9100?
2. if my current band firmware not support T-mobile 4G, which version band firmware is recommended?
thanks in advance!
Jeff

You won't get "4G" on T-mobile in the US with this phone no matter what you do. It lacks the HARDWARE capabilities to receive 1700 mhz for data. So it will only get up to Edge data speeds.
T-mobile USA's 3G and "4G" operates on the AWS band, which REQUIRES BOTH 1700 and 2100 mhz, as it uses one for uplink and the other for downlink.
If you want high speed data on the carrier's network, you will need to use AT&T, or someone who operates on AT&T's network, like StraightTalk or H20.

Hey guys, I just got my new HTC hero. I'm with AT&T now and having the unlimited 3G data plan. I setup the configurations of APN settings as following:
Access point: wap.cingular
Username: [email protected]
Password: CINGULAR1
But I only see an "E" at the connection status which I believe indicates EDGE. Can anyone tell me how to get 3G work on this device?
Thanks a lot!!!
I didn't realise the hero was out in the us yet but if it is i don't know why and if it isn't out its because i don't think it surpports american 3g networks i think you can only get 2g.
Yes I got this phone out of the US.
So you mean there's no way at all to get 3G to work on this phone with AT&T or any other carriers?
In its current state the phone does not support the AT&T bands for 3g.
There are rumors of an AT&T version coming October 11th, that would support 3g.
European/Asian version of this phone does not work with US 3G. AT&T's 3G network requires the bands 850 & 1900, while T-mobile's 3G requires the bands 1700 & 2100. European/Asian version supports only the bands 900 & 2100.
Does this mean T-mobile 3G may work on this phone?
T-Mob's 3g should connect to this phone, if you could find a signal, haha.
http://www.androidauthority.com/index.php/2009/07/03/htc-hero-approved-by-the-fcc-with-att-3g/
Neither T-Mobile US nor AT&T will work with this phone for 3G. The only version of this phone that exists at the moment supports ONLY European 3G. There are rumors of the device coming to AT&T, but nothing confirmed. IF that happens, the new phones would work, but that wouldn't change the fact that the device you have will still only function on Edge.
Sorry to be the bearer of bad news, but it's true.
It's actually Sprint pal. Also, there was a picture for Tmobile also (this appears to be a rumor).
T-Mob uses the 2100 spectrum so i dont see why it wouldnt work.
And a CDMA and a GSM (With AT&T 3g bands) has gone through the FCC recently.

No, it won't work with t-mobile USA's 3G network.
Yes, T-mobile in Europe use the 2100 band for 3G so the Hero works. But T-mobile USA use 1700 and 2100 bands for 3G, and you need a phone that support BOTH bands to connect to its 3G network.
Unfortunately, unless T-mobile USA decides to carry this phone (and they have already said that they wouldn't), there won't be a version of Hero that support its 3G network. This is because T-mobile USA is the only carrier in the world that uses the 1700 band for 3G. You may ask why T-mobile uses different bands for 3G in different countries. This is more of a regulatory decision than a business decision. If you are interested, go read about those FCC spectrum auctions.
All in all, European/Asian version of the Hero won't work with any 3G network in the US. The product id of the European/Asian Hero is HERO100, it supports only the bands 900 and 2100 for 3G. There will be a North American version with product id HERO130 that supports the bands 850 and 1900. It will be released either on AT&T or on the Canadian carrier Rogers, because only these two carriers use these bands for 3G. Currently it is not know whether it will be on AT&T or Rogers, but that latter is more likely IMO. Finally, there will be a CDMA version, with product id HERO200, for Sprint. This is more or less confirmed to be coming in October.
T-mobile US 3G uses 1700 for down and 2100 mhz for uplink. So 2100 alone isn't enough as you need both directions to connect.

Thanks! That was very informative, although it totally crushed my dreams of owning a Hero while remaining on the T-Mobile network.
Hey,
The T9193 version of the HD2 has the radio bands 850/2100 in it for HSDPA 3G speeds, but just the 850 band is needed to support AT&T's 3G service in the US.
Would it be possible to create a new radio ROM that disables/turns-off the 2100 band for U.S. users, since this band is useless anyway, and it may help extend the battery life of our HD2 by not having to power the 2100 section of the radio, especially if it makes any transmit attempts by the phone on the 2100 band (transmitting uses a lot more power then receiving).
Any chance of this?

T-mobile is also using HSPDA/3G @ 850 also and nowhere else? I hope so because pretty much half or better of the users of these forums are T-Mobile and *not* AT&T subscribers. Jus sayin.

ROM cooks do not have such fine grain control over radio bands.... Sorry.
I don't believe the T9193's radio has the 2100 Mhz band, otherwize I'd be able to use it in my area to get 3G coverage. (We only have Edge on the 850 Mhz band here)
Hopefully someone who knows for sure can answer this.

I'm pretty sure the T9193 has the 2100 band, but 2100 is useless in the US because AT&T uses 850/1900 for 3G. The T9193 is an Australian phone made for Telstar (their cell phone company). The 3G bands used over there are 850/2100. So, because AT&T also uses the 850 band, thats why we are able to use this phone with AT&T's 3G here over in the US.
However, the 2100 band of the phone is useless in the US because is was intended to be used for 3G in australia.
The good news is that AT&T is phasing out the 1900 band for 3G and switching everything over to 850, so the HD2 will just get more and more 3G coverage as time goes on and then even the 1900 band won't be used anymore so it would be irrelevant if the HD2 has a 1900 band or a 2100 band because both would be useless.

Well, you neglected to say where "here" is
The best available combination for world-wide 3G access is 850/2100 Mhz. This is because:
1) 850Mhz is used in Canada, US, S Americas, Aus, S Africa for 3G broadcasting in regional areas (and in some city areas)
2) 2100Mhz is used in Asia, EU, Aus cities for 3G broadcasting
This is due to the actual physics of velocity = frequency x wavelength
Some telcos use 1900Mhz in the cities, but also broadcast in 850Mhz
Other telcos use 900Mhz in the regional areas, but also broadcast in 2100Mhz in the cities
ATT in the US uses 850mhz in the regionals and 1900Mhz in the cities. This ensures that "their" PDA's cannot use other SIM's - I have no idea why the dumbed-down US market meekly accepts that
The perfect combo is tri-frequency hardware, such as PDA manufacturers used to provide but do not any more (no excuses, it's just straight cost-cutting and sleight-of-hand marketing BS to suit the greedy telcos)
The HD2 released in Aus through Telstra is hardware-filtered for 2100/850 Mhz, the best available combo for world-wide use (not perfect, of course)
The HD2 released in EU/Asia is 2100/900 Mhz. This will access 3G in most cities world-wide (note that China uses 2100/850) but has limited coverage in regional areas - yes, I know there many 900 Mhz deployments but these are very limited geographically
The HD2 released in the US is 1900/850 Mhz. This is very limited for world-wide cities and excludes 3G coverage for those countries that use 2100/900 Mhz
None of this has any relation to GSM coverage, so please do not confuse them
Is the hardware actually different?
I live in NZ and unfortunately bought a T-Mobile unit which is set up for 1700/2100mHz which means that when in the cities I get full broadband, but in the regions I only get dial up speeds through GSM.
My question is does anyone know if the hardware could actually use the 900mhz broadband - or is it a pipe dream on my part that hopefully someone will release a ROM to access some previously hidden hardware?
I do recall with my Touch that there was a GPS built into the hardware that no-one was aware of for a year or two!

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.

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.
Sent from my Xoom using XDA Premium App
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.
Looking for any insight to using the SGS2 on TMo and getting anything better than EDGE speeds.
As I understand it (via wikipedia) TMo has these bands:
[TMobile USA] owns licenses to operate a 1900 MHz GSM (Global System for Mobile Communications) PCS (Personal Communications Service) digital cellular network and a 1700 MHz/2100 MHz UMTS AWS (Advanced Wireless Services) digital cellular network that cover areas of the continental U.S., Alaska, Hawaii, Puerto Rico and the U.S. Virgin Islands. It provides coverage in areas in which it does not own radio frequency spectrum licenses via roaming agreements with other operators of compatible networks.
And then from Samsung's website:
Network
HSPA+ 21Mbps/ HSUPA 5.76Mbps
EDGE/ GPRS Class 12
Quad band GSM 850/900/1800/1900
Quad band UMTS 850/900/1900/2100
So, what gives? Seems like the 2100 UMTS service should match up between the two. Is this an issue because TMo is somehow blocking the use of the unbranded phone on their system? If so, and on a much more advanced level, I'd think there'd be a way to make TMo think I'm using the PoS smartphone they gave me to use on their system... or am I smokin' that crackberry?
Needs both 1700 and 2100 if I remember correctly.

One is up and the other is down so you need both 1700 and 2100 to use T-Mobile's data network. No version of the SGS2 any where in the world supports T-Mobile's AWS bands. T-Mobile's getting a dual-core version of the Infuse in September that supports their bands.

What's the chance of one of those "Hercules"...SGS2 by another name apparently...having an antenna board that will drop into another SGS2?
I see a lot of brilliant software hacks and tweaks around here. Don't see a lot in the hardware realm, tho (like a new antenna board, for instance.) Is this not the place for that or is that at a completely unrealistic level of development?

You'll need an antenna engineer with a test chamber to tune the antenna. A lot of factors play into more than just fitting into it. You might have to play with different patterns depending on how much different the overall phone mechanics and materials are from Hercules to the SGS2.
Hi,
I bring my international version GS2 I9100 in US and using the prepaid 3G data plan. However, it can only connect to GPRS or EDGE. Is it related to RADIO version or it is a hardware issue?

The phone is connecting to edge because T-Mobile's 3G is on 1700 for HSDPA. You would need to switch to AT&T for the international one to work on 3G.

Partially right.
T-mobile USA uses AWS for high speed mobile data. AWS requires both 1700 & 2100mhz UMTS, as it uses one for uplink and one for downlink. This phone does get 2100, but doesn't get 1700. So it's limited to Edge on T-mobile USA.
And yes, it's a hardware issue. Sorry.

Thanks for the clarification. I had been wondering why I was unable to understand why carriers were listing two frequencies and just understood the phone needed to match what the carrier was using or vice versa. I should of realized that earlier but yes, up/down link makes sense.
In a way it is hardware or carrier compatibility issue depending on what the OP's point of view being.

Hardware from the point of view that the antenna hardware does not and will never receive 1700 mhz UMTS, carrier compatibility issue from the point of view that T-mobile USA uses AWS, which requires both 1700/2100 UMTS, and the phone doesn't receive 1700.
Same thing in my point of view.
