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...
I bought my HTC Diamond on UK. I updated the ROM to the RUU_Diamond_HTC_HK_WWE_1.93.831.1 this was supposed to make my phone QuadBand. It does work in USA (Boston) where I live. But I have never seen my phone doing 3G and speed test top was around the 1xx kbps.
Any Ideas?
PS. I am on the ATT network
Are you sure you have 3G coverage in Boston? Do you have a USIM-card (which I was told to be required for UMTS stuff)?
3G speed
I did look at the ATT coverage map and it said that I do have coverage.
How do I know what type of SIM I have? The SIM does have the 3G logo on it.
Are you sure your phone has the bands?
Check the Band setting, Settings->Phone->Band,
in the dropdown box for "Select your GSM/UMTS band", my US 3G ATT phone shows the following options:
Auto
UMTS(850+1900)+GSM(850+1900)
(oddly enough, the settings have to be on Auto for the phone to work..)
When I bought my diamond, I was curious about my sim too, so I took it into the ATT store and asked if it was the "latest 3G sim" and he said yes. Mine is half white (top) & half Blue (bottom), with a orange 3G fireball in the topright corner.
If yours matches all that, then take it to the ATT store and see if you get 3G in the store
Also..if you have doubts, I've had multiple Sales reps in the store tell me I can get a new Sim for free at any time, just need to ask.
3G
I do have that SIM half blue half white with the 3G fireball logo.
On my select network I have
Auto
GSM
WCDMA
on the GSM/UMTS band I have
Auto
UMTS(900+2100)+GSM(900+1800)
UMTS(850+1900)+GSM(850+1900)
UMTS(800+2100)
UMTS(850+2100)+GSM(900+1800)
UMTS(850)+GSM(900+1800)
UMTS(1700)

What ROM do you have?
RUU_Diamond_HTC_Europe_1.93.401.2
RUU_Diamond_HTC_Europe_1.93.401.2
Does this ROM supports USA 3G????
Sorry for my English
You have the European version and have only HSDPA 2100 / 900 (3G) and probably ATT works in HSDPA 850 / 1900, if this is the problem, sorry 3G is impossible for you, because is a hard problem, not a soft problem, search in this web there are many post about this. The European is quad band in GSM but not in HSDPA (3G)
CArlos
How about if I use another ROM
If I use another ROM ? would I be able to do 3G?
No I think it's impossible since it's different hardware I believe.
I think the one you have from UK, it only contained HSPA 2100 and US /Canada is using HSPA 850/1900, that's why you don't have the 3G signal.
Quad band only for voice and EDGE.

I'm using the stock rom/radio for the Unlocked US 3G.
1.93.422.4 WWE
1.00.25.08
But I missed the fact that you're using a European Diamond. sorry.
is there any conection betwen 3G and front camera....
i think i have an Eropean model from UK Vodafon which has the front camera... but i am not sure about 3G !

Hello! I`m from Brazil and I bought a HTC Diamond unlocked in US this month.My operator works in a 2100 Mhz 3G frequency, compatible with the HTC.Butt it can`t find the 3G signal, only the GSM. I tested an other operator SIM Card, wich works with a 850 Mhz frequency and the 3G was perfect!Does a Radio Update can fix this problem?
Rom Version> 1.93.422.4 WWE
Radio Version> 1.00.25.08
Thank`s!

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.
Got an used Captivate on eBay, came with kernel 2.6.35.13 Glitch v13.1, MIUI 2.2.17, Android 2.3.7 and modem UGJK4
Well, Captivate radio specs for 3G: HSDPA 850 / 1900 / 2100
My operator (TIM) uses 2100 in my city, excellent until now!
But, I'm stuck in EDGE, can't get it to connect any faster. We have other phones here got from England, Ireland and USA, all of them support 2100 and 3G works perfectly, but not this Captivate.
Already tried the following modems: UGKG3, XXJTV, XXJVU and currently on UGJL2.
Just after installing the UGJL2, it connected at HSDPA, but after 5 seconds changed to Edge and no (H) anymore
A weird thing, I tried another operator chip (VIVO), that also operates at 2100 in my area and HSDPA is enabled normally!
Got back my chip and back to EDGE, this same chip get 3G+ (HSDPA) on a Samsung Jet, Samsung Galaxy Mini and a Samsung i550.
Everything else works perfectly, calls, GPS, wifi...
Any tips?
Thanks!

From what I know, the Captivate only gets 3G on AT&T even when unlocked. I might be wrong, but I remember reading that somewhere.
Must be a myth, I use my captivate on 850mhz in Australia 3g and hspa work perfect.
Did you try to force 2100 with service mode?
Phoned in.....
But with the other operator chip 3G works normally, at the same place where my chip also get 3G on other phone. Both are 3G+ (Hsdpa) able, but not when together. That is what makes no sense.
I would have forced in servide mode, but all the codes for service mode does not seem to work, and I've seen around the forums that MIUI don't have it...
Is there any code besides *#0011# and *#*#197328640#*#* ?
Both not work here
Thanks for the help!
MIUI and AOSP do not allow for the forcing of certain bands. You can specify what region you are in, but that's about all. To do that, use dialer code
*#*#4636#*#*
Phone setting
Menu/select service bands
That's about as good as it gets.
Hope it helps.

Your carrier uses the same 3g bands that att does. Those are the only ones that use the same 3g bands

Yes, I've tried Automatic and Euro (same bands used here), still Edge.
The strange thing is it get 3G from the other operator, that uses the same 2100 frequency... (at leaset they say it's both 2100)
Any way to see the frequency currently in use?

My carrier uses 850 and 2100.
My wife has a captivate also, her carrier uses 900 and 2100. Of course only the 2100 works but it is solid.

Ok, I discovered that it's an area problem probably, I tried at the office and got the H on the indicator! HSPDA is working, sometimes 'came down' to 3G (concrete building, not so good signal).
That's still strange because my friend get Hspa here, with a Galaxy S (I9000b), same operator, will call them soon to ask about this.
Anyway, it works! with ridiculous speed (180kbps), but it's better then Edge at 15kbps...
Thanks everybody for the help!
