3G in the USA

Has any been able to get 3G to work in the USA yet?
thank you,
jdm

I would say that it is imminent that the US version of the S730 will be released soon. AT&T or T-Mobile may pick it up (T-Mobile's 3G network in NYC just went live, but there are no phones). If so, I would suspect that some of these crafty folks (like Alcaline) would be able to extract the radio ROM, and make it available for the S730 that we all have (the european version).
But, here's the most important part... It all depends on whether or not the European version of the S730 has the radio chipsets that will support 3G on the frequencies that are 3G in the US. There is no known answer "available" to this, so it can only be discovered by testing.

The current S730 uses the 2100 band for 3G speeds and ATT is deploying 3g on 1900 and 850 I believe and they sell a decent ammount of 3g phones. T-Mobile is working on setting one up on the 1700/2100 band but I dont care for T-Mobile.
I have watched my phone at times flip into 3G mode for a few minutes then revert back to Edge, its trying but cant work properly without the right frequencies.

Check out the chipset datasheet. Bottom of page three explains the specific radio chipset combos and their support for different freqs.
I suppose, to save on manufacturing costs, they could have used the single chipset that supports 3G on all freqs (RTR 6285), but I believe this is unlikely due to the difference in model number that was submitted to the FCC (European version: WING220, US version: WING200).
Who knows though.

3G in US
Hermes models had different model #'s HERM100, HERM200 and had the same radios, in some cases minor difference such as case style, i.e removal of video calling camera etc. With any luck we have the RFR6500 + RTR6275 Combo, or as you mentioned the RTR6285 and just not a radio rom that allows 1900+850 3G. I was looking on the FCC site and they have some interesting screen shots, one of which shows one(s730) with what appears to be the front camera covered up and another which shows a radio rom(R 0.27.03.05B), one that, to do the tests would likely need to support 1900+850. Check Page 250 / 11 in the PDF. However, also in the test is the lack of any mention of 2100 Mhz test, which would suggest that either the US 3G Radio won't support 2100Mhz or that it indeed has different hardware that won't support 2100Mhz. At any rate it would be interesting to know if anyone has tried to flash one of the pre-prod roms for the wing 200 onto the wing220 and see if they are able to connect up to 1900+850 3G.

I suppose only time will tell.

Wow... nice investigative work. Very interesting. I'll start hunting around for the ROM.
[edit]
Searched google and, my favorite, napalm with no luck. I wonder if we can lure an FCC testing engineer into the XDA-dev realm. muahahaha

I was searching some of the other posts, and it appears that most of the pre-prod radio rom testing had been focused on GPS functionality. Has anyone been able to throw on any of the pre-prod radios with an ATT SIM and tested to see if it can connect to WCDMA -> US Band (1900+850) ??

I have no possibility to check the 3G in the USA from my location in Norway.
But just to get this clear, because I have changed my Radio more often then most people change their underweare.
Is everybody able to select WCDMA and then US Band in the settings?
I dont know if this is selectable on all devices or if this is made available after my radio flahings.

I believe all S730's have the following options available.
Network Type:
Auto
GSM
WCDMA
Band Type:
Auto
US Band
Euro Band
Japan Band
For it to actually be able to operate on all of these frequencies I believe it would need to use the the RTR6285 chipset as the other 2 combos would not support all of the different frequencies combinations.
US Band -> GSM 850+1900 / UMTS 850+1900 (ATT)
Euro Band -> GSM 900+1800 / UMTS 2100
Japan Band -> UMTS 2100+800 (not positive on this one)
If I change band to from Auto -> WCDMA I do not get an error but no 3G Icon and all calls fail. If I then go and change to US Band while having WCDMA selected it indicates that it cannot change to that GSM/UMTS Band. Also interesting, If I stay on WCDMA and select Euro Band, no error, but of course all calls fail. I then tried to change to Japan Band, no error and no phone calls. Finally I am still on WCDMA and I switch to US Band and I get the error that indicates I cannot change to that band. So, I would be interested to know Alcaline if you see the same behavior on some of the other radios you have been trying to see they allow the switch to WCDMA / US Band combo.
Thanks

Can anyone else confirm this behavior on any of the other Radios out there?

I have the ability to tell my phone I am in the states, but it does nothing (default settings though)

Was the US version (WING200) of this phone ever released? Or has anyone gotten the EU version to work on any US 3G networks? Wondering about T-Mobile...

TD Japanese Version couldn't use the WCDMA(2100) Network in China.
This TD seemed to use WCDMA 1700 in Japan, but couldn't be used in China. I've tried flashing a few Roms, also some Radios. Still it didn't.
Is this TD only support 1700MHz in Japan, which means it couldn't be used in WCDMA Network in China, which is 2100MHz?
Sorry for my poor translation.

The translation is better then the kanji. {I can't remember Katakana or Hirogana, been too long since I have read, wrote, or even spoke} If you can translate this back for Shishi, that would be wonderful. Thanx for the help as a translater.
Check the model # {label under battery}, & enter the model into the search engine @ PDADB.net. This will list all the frequencies your specific model is capable of. Model # will be DIAM*** {replace the *s with the #s on your Diam.}
You can flash ROMs until the chip burns out, but this will not help, because all the frequency data is in the Radio. If the site says that your model is capable of 2100 {which I believe it should be}, then just find a radio that runs at 2100MHz, & flash it.
If this is a CDMA model then I am not too sure what the frequencies are. GSM Touch Diamonds are quad-band phones & definately utilize the 2100MHz WCDMA. Soe GSM Diams only show the tri-band frequencies, but if you just flash a quand-band Radio to it, & it'll be fully functional as a quad. It has the Hardware, you just may need to change the software.
Also, if you go to the phone settings, there is a tab for "Band". Look there & see if the 2100MHz is listed. If it is, check that it's enabled. If it's not then just flash a quad radio.
Good luck

Thank you for your help!
检查你的TD的型号（取下电池你就能看到），将你的手机型号输入PDADB.net的搜索引擎，它将会列出你的型号所适合的频率。型号是DIAM***。
你可以刷ROM，但是这没有作用，因为所有和你频率相关信息都在Radio里面。如果你的型号适合2100Mhz，那就选择一个2100频率的Radio，再刷Radio。
如果这个TD是CDMA型号的，那么我也不清楚他能适合频段是多少Mhz。GSM的TD是4频手机，所以口肯定能使用WCDMA的2100Mhz。GSM只显示3频，但如果你刷了四频的Radio，它就是个全功能的4频手机了。你只需选用合适的软件来激活它的硬件。
此外，如果你进入手机的设置项，其中有一个频段(BAND)选项，看看是否其中有2100Mhz 的频段，如果有，只需启用即可，如果没有，则需要刷一个4频段的Radio

Change rogers radio frequency to 3G

Hello everyone,
I bought a G1 from Rogers in canada, but now I live in germany.
I don't know how it actually works, but I have been unable to get 3G connections here (only GPRS and normal cell phone), using the O2 company. After doing some research I realized that the radio frequencies are different (according to http://www.gsmarena.com/network-bands.php3?sCountry=GERMANY, then go to canada to check it out).
Are there any possibilities to change the radio frequencies of UMTS? My phone is rooted.
Thanks a lot!

Dial:
*#*#4636#*#*
Then goto phone info
Scrool down list
Change preffered network to WCDMA only for 3G only
Exit
Edit: O2 doesnt use the same 3G freq as Rogers, so you must stay with EDGE.

if memory serves correctly - o2 and tmobile work on the same frequencies in germany
if this is the case there is nothing you can do as the radio frequency is a hardware thing

Thanks for the reply!
I did that, but after a while it changes back to 'WCDMA preferred'.
I went to the O2 store, and the guy tested the chip with a Palm Pre, and it worked fine.. but with my G1 it didn't, only GPRS.

rogers use different frequencies to most other providers worldwide
rogers, atnt and some south african one use one set for 3G but everyone else uses another
you WILL NOT get 3G on the rogers dream on frequencies not used by rogers

also

will this work with any phone? Sorry NTT. i have just bought a htc touch 3g but it won't work in the bush. the phone supports HSDPA/WCDMA:
900/2100 MHz and out here we have 850/2100 mhz wcdma.

All I know is that it allows you to force a specific phone freq, im not sure if all HTC phones have test mode which that number brings up. It doesnt allow you to change the freq only force one type. So a quad-band phone can be forced to use 2G only instead of 3G.It doesnt give access to unsupported bands cause thats a hardware thing.

I am discussing this very subject here: http://forum.xda-developers.com/showthread.php?p=15461093&posted=1#post15461093 would appreciate any comments or suggestions.

[Q] Will international SGS i9000 work in Canada?

I have a factory unlock international SGS version. I'll be moving to Toronto Canada soon. I would just like to know if my phone will still work when i arrive there. If not, is there a way for me to make it use 850mhz? Does is help if i'm running CM7?
Thanks in advance for the help!
mike

your phone is the international version, so it will work all around the world.
i assume your not a noob when it comes to flashing as you are currently on CM7 (not the easiest rom to install)
so if you do run into any trouble - mainly signal issues (which you shouldnt) a simple modem change should work
but i use JVO modem in UK other people use this modem in India, Australia and so on, works for them, works for me... you will be fine.

You will be ok as long as you have an 850/1900 modem

Thanks bro. The reason i'm asking here is because i read on several forums that not all SGS international phone have the hardware to support 850 band frequency. Meaning even if i change the modem that support such frequency, it won't work as there's no hardware to support it. But then again, I don't have any idea if this are true. Would you know any truth about this?
Oh by the way, at first i thought installing CM7 is hard, but once you finished reading the install instruction everything is smooth as butter.

Just want to ask, if i don't use modem that has these frequency (850/1900) for my cm7 sgs, would i still be able to use my phone? Please correct me if i'm wrong, these bands only lets me connect to 3g or hsdpa and has no effect in terms of making and receiving calls/sms?
Thanks again!

I don't think that is true at all, it's not a hardware issue, it is firmware, you just have to make sure your baseband firmware supports 850.

These bands are what connect your SIM card to carriers.. so yes you need these bands. Whatever carrier you are with will depend on your band.. in Canada for example. Bell and Telus use both 850/1900 mhz bands depending on location, Rogers I believe on uses 850... so if your modem, is 1900 only and you are in an 850 area, then you will have no signal and usually recieve an error like "SIM not compatable with carrier" if you try to force a connection.... the APN(access point names) are what connect you to 3g etc..

[Q] HTC ONE wrong frequency band

I bought an HTC ONE factory unlocked international version in Amazon, there it said it supported the 900mhz frequency on 3G, cause where im located thats the 3G frequency, it doesnt, it stays in EDGE. Is there any way to fix this, flashing the rom/radio or something to make it pick up that frequency, or im stuck with this?

For now you're stuck with that.

Have you rooted? I suggest installing the Cyanogen-m7 Nightly on your phone. To set up the connection when it's installed, do Settings>Wireless & Networks More...>Mobile Networks and then choose your settings.

You're pretty much stuck there permanently unless you consider returning the device. The difference in the frequency is hardware so you won't be able to fix it unless you rip open the HTC One and replace the modem chipset there.

Hello, But what if the hardware is the same?
I have the 801n model with the CID O2_102. I live in South América and as I've seen, the hardware can use the 850MHz 3G band but it seems that it's locked. I think ATT phones are 801n too.
Changing the radio will unlock the bands?
Thanks in advance.
EDITED:
I contacted HTC Support Center and they confirmed that this equipment should work in the 850 Mhz 3G Band.
"The HTC One 801n indeed supports the 3G frequency 850 MHz. What I can recommend is to verify with your carrier if the network settings are correct on your device to ensure the proper functioning of the 3G connection."
Network settings are ok, I still think this is a software block.
