Does Diamond support USA GSM bands? I think mine do.

Correct me if I am wrong but I think my Diamond (bought from Hong Kong) support USA GSM network. Please see the attached picture, it shows UMTS8500+1900 + GSM850+1900 as an option in the phone setting manual.
I made this post because I saw many people complain that the first batch of Diamond doesn't support USA GSM bands but only the Asia and Euro one.

Can u check al lines, mines is:
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)
Mine is working is USA!

It may support those bands but it wont actually get you 3G access in America because the non American Diamonds are missing the 3G attenna. Its not a software problem but a hardware problem.
If you want to use 3G in America then wait till the American version of the Diamond is out.

the bands being able to be selected means that the RIL (radio interface layer) CAN support those bands, that DOES NOT MEAN that your Phone Hardware can support it.

The software interface is probably not smart enough to adjust itself to match hardware.
The HK Diamond hardware spec said it is a triband GSM phone. It does not have GSM850. I'm not sure if this is just a marketing / sales spec.
Anyone tested this in the US? Or any hardware/radio engineer on this forum to validate this spec?

Well the HK Diamond Spec is incorrect, it "could" be quoting the US specs but the US version isnt out for another month at least.

900/1800/1900, thats 3 bands = triband.
This has been discussed so many times now
I have myself written about 3 times why techincally it won't work. Search for my posts, because i really dont have the energy to type it agian!

I though this would be a good place to post this question.
I have the same bands listed as post # 2. Now my phone came out of the box like it is. No radio or rom upgrades, yet. Does that mean its Quad band unlocked already from the box? Or do I still have to load the latest radio?

Hard to say without knowing wich radio you have.

My radio is 1.00.25.03, so I would assume it's not quad band without putting one of the newer radios?

triband TD
when i got my TD, it was listed a triband. I could still use in the USA because
ATT uses 900 band also. However, their primary band is 850. THe reception with the 900 only band was spotty. I then flashed my ROM (see below) and a new radio.....05 and immediately got 4 bars where i got 1 or none. MUch improvement. However, you will NOT get 3G until you get a USA phone. It uses Edge now, (which for me is fast enough). ITs a hardware think not a ROM or radio upgrade thing to get 3G.
BTW this is my current ROM and i am very happy with my TD now. Best phone ive ever had.
Rom 1.93.456.2 WWE
Rom Date 7-10-08
Radio Version 1.00.25.05
Hard SPL 1.24
Protocol Version 52.29.25.12H

I saw your auction. Sorry, but I can't believe you're getting 3G on that phone without at least ONE bar showing in the pic!!

If the european version is missing the antenae then if he was in an area with strong enough signal wouldn't it show the 3G icon and maybe even only one bar, but that is not usable.

The 3G has nothing to do with the bars.. it says 3g next to the bars if you have it.. (at the same place as the active sync icon is) I haven't seen the picture though so I'm not going to say anything..

So that makes me wonder why you haven't dumped the radio off the phone and let other people test it out. If in fact it is just a DIAM100 model with a modified radio to unlock the 850 gsm band.

Dual Sim

Anyone is using a dual sim with the Diamond? I have seem a couple of dual sim cards that it´s supose to work in Diamond but I am not really sure... anybody knows a model which works right on Htc Diamond?

Hi. I've been using a dual sim on my previous WM phones with no problem. Will try it on Diamond in a few days when I get back home, and will let you know. If you don't hear anything by Wednesday - Thursday, pls PM to remind me.
I have also used a very nice prog for changing swaping between the 2 cards on the Today screen, but I guess that if you use the HTC today, will not be able to use that one, and you would have to go through Start\Programs.

Hi, I'm using SIMore Black 1 in my Diamond. It's working well, but do not expect use 3G or HSDPA.
SIMore is compatible with 3G phone, but doesn't work if you use 3G, you only can access to GSM band...
I contact the support, and they let me know that I've been screwed... They do not garanty 3G use...

I have an analog dual sim adapter inside my o2 xda diamond and it works perfectly. My girlfriend has the same one in an htc diamond and it's working there too. Never had any problems with it. HSDPA/HSUPA working just fine. I believe it's a MagicSim 1st generation adapter.

Ok thanks I'm gonna look for this on google.
@Smaniac : it doesn't work on any SIM. In fact, if I let the settings in Phone\Band on auto, no way to get network on both sims. The only way to get it work is to set it on GSM, and then no 3G or HSDPA...
EDIT : I'm in France, using Orange and SFR Sims.

Thanks all
christis, ok I will wait for your answer
chineseseleper, can you check and tell us exactly the model? I have read in other forums people who say that MagicSim doesn´t work in Diamond. The MagicSim you can find at this moment I think is 20th

Are you using the new 6.0 version or an earlier version of the SIMore Black 1 ?

I have been looking at this one and if you go on you tube there is a video for it to.
Anybody using it or know of it?

this is interesting! dual-sim-cards!
so how does this work, I checked out the magicsim website, it's not really clear there..
so, is it possible to recieve calls from 2 different sim cards without switching around?

all new apdapter don't work. you need the oldest ones, the analog ones. they don't interfere with the sim card. i don't know where to check which model i have, but i believe its 1st gen.

Sorry for being late in replying. I messed up my main sim during cutting, and although it works on it's recovery adaptor, it doesn't work on the dual sim. it is 100% sim problem. Otherwise, the dual sim adaptor (2nd generation) worked perfectly in my previous WM phone (asus P526).
I will try to change my main card and check the diamond, with the software I mentioned before, on the today screen (the one that the card installs in Start\Programs, shouldn't have any problem.

Anyone got any new info so as if v6.0 of SIMore Black works with 3g/HSDPA???

I don't know if it can be of any help http://es.youtube.com/results?search_query=htc+diamond+simore&search_type=&aq=f

All I've seen so far is that dual sim works on 3G phones, but I've never seen the 3G band in action. Every demo is GPRS/EDGE only.
So the question still stands, does the dual sim adaptors give me access to the 3G band?

Diamond and AT&T 3G network.

Hi everyone:
I just bought a new HTC Diamond and brought it back to US.
In US I'm using AT&T and my previous phone was HTC TytnII which also brought from Taiwan.
When I was using TytnII, I can get 3G signal with no problem at all.
However yesterday when I get off the plane and put my ATT sim card into my new Diamond, I can only get EDGE signal.
I read some threads in the forum already and I found out that maybe is the radio's problem.
Now here is my question, I checked my config of the radio option in Diamond and I found out that I did have the option for UMTS(850+1900) which I know that AT&T use this freq. for 3G network. So how could I still have no 3G signal after all? Is this a hardware limitation? Or should I upgrade my radio rom(I think I'm using .05 radio right now since I haven't upgraded anything.)
Please help me out here because I really have no clues...Tks.

try installing or have it sign in on att network...check your network setting...or find htc network config cab that should do it.
make sure that its sign in on medianet or pda plan which ever you have. you can google att network sign in

Did you buy the U.S. 3G version? It's got a bigger battery(1350) and a rubberized battery cover.

I tried using Network Wizard to reset but still no good news.
Can you tell me what kind of data plan you are using right now?
Mine is 19.99/month but I know there is a PDA data plan.
I'm wondering maybe it's the data plan that restricts me from 3G network.
However I'm still able to access MediaNet network via EDGE though.

No it doesn't. I had a US Diamond purchased from Best Buy, and it looked identical to the European version.
To the OP:
Unless you bought the US version of the Diamond, it does not have the hardware necessary to connect to AT&T's 3G network.

He was confused. The CDMA version in the US (and Telus in Canada?) has the larger battery with the non-faceted back.

I don't want to sidetrack this thread, but I don't believe you bought the unlocked US 3g version. Mine is missing the front camera (different then the european version), and it has the 1340 battery and "rubberized" backing. Bought mine through bestbuy also.

Agree with rpassmore. I bought mine from Best Buy and it comes with the bigger battery and different battery cover (it's different both in that it's rubberized, and also bigger to accomodate the bigger battery).
Perhaps the confusion is such that the latest Euro models also include these upgrades?? In any case, the first run of the Euro model was a few millimeters thinner due to a smaller battery and battery cover, and the battery cover also had a shiny finish too.

The Diamond I bought from Best Buy ($699) had the faceted back similar to the Fuze. I didn't pay attention to the battery since the phone was too small for me overall.

unlocked TMOB device only showing EDGE on AT&T - help

hi all, I bought a TOB locked device which worked finme on TMOB, getting 3g and H all the time. i had to move to AT&T so I unlocked the device (thru TMOB) and got the appropriate service at AT&T. But my device only shows EDGE. Card shows 3g in an iphone so it isnt that. Anyone know why im only getting EDGE???

ATT and TMobile use different 3g bands so EDGE is all you will ever get. Same thing happens in reverse until there are phones that support both sets of bands (not likely).

well thats just GREAT!!

To expand on what you said, they use different 3G bands AND the hardware that is able to talk to said bands is exclusive to both AT&T and T-Mobile TP2 phones. There is a physical hardware difference between the two, so upgrading to a different radio will not allow you use your T-Mobile TP2 on AT&T's 3G network, either.

Aye. It's like with my wife. She has a G1 right now with T-Mobile. However, her friend has a MeToo (iPhone) with AT&T. Of course, she wants the iPhone now and told me that other day that she can get one that is already unlocked for use with other carriers. I had to explain to her that I would get her the iPhone if she wanted, but that she would NOT get 3G while on T-Mobile's network given the hardware constraints. She didn't say much after that.
Research is key. I see it every day in the NRG ROM thread. People see "Manila 2.5" and immediately grab that version. However, they fail to research and don't realize that Manila 2.5 is still in its beta form from HTC. They ask why certain functions don't work...they even seem surprised when they don't work. When explained to them that it is still in beta form, they quickly go back to lurking.

ditto on that, where I live we don't get stable 3g and when we do I don't notice any speed advantages. When I drive to atlanta where they have a stable 3G I only noticed that google maps DIDN"T like to even connect at 3G. And I wasn't really using anything else while there, I actually disabled the stupid 3G radio on my pantech just so I could use google maps. Sooo... never really had it anyway and got tired of waiting for ATT to drop their TP2 or even the TD2. bought a TM TP2 and I've been in heaven ever since. Phooey 3G... who needs ya?

i've been with tmobile forever and this is my first taste of 3g, and i gotta say, i was much more excited about it than actually having it. i get 3g in my area and it makes nearly no difference in what i do with opera mini.
espn will load a hair faster and i finally get a good slingbox stream, but other than that, i wouldn't die if i had to go back to edge

You will see a MUCH bigger difference when you aren't using a browser that compresses the data before it gets to your phone.
Opera mini does just that. Thus, you won't see much of a difference between Edge and 3G. Skyfire also does it as well, I believe.
When you start downloading "raw" data, though, you will really see the difference in speed.

[Q] HD7 for AT&T/Telus

I bought my HD2 from Telstra to use on AT&T. When I received it I couldn't get it to work on AT&T with the factory ROM and had to HSPL/Reflash it. What are the thought on the HD7 from Telstra working with an AT&T sim on the AT&T network? I would really hate to go back to a smaller screen and honestly the surround seems a bit kitchy.

You probably will have to have it sim unlocked. Thats easier than flashing a rom, but with WP7 I don't know.

i want to do the same thing i need an HD7 on at&t

i am on the same page
I am using a telstra hd2 on us att 3g, i switch between wm 6.5.x and android 2.2 desire rom, i've been using android a lot more lately, because i got tired of squeezing functionality out of winmo when its already there with android (tired of second rate facebook, foursquare apps etc ), alas i really want WP7 to succeed and will be there to support it, but i do not want to downgrade to a smaller device to stay on at&t, I have a cheap unlimited data plan (at&t thinks im using a
little nokia phone for data), the A list where i use my google voice for calls and have accrued over 3,000 roll over minutes,so it looks like ill be forking over $800 bucks again for a telstra hd7 if that's the case, i imagine though when i sell my unlocked hd2 running on att 3g network with dual operating systems i may get a decent penny on ebay to contribute towards the telstra hd7 purchase
and also has anyone else using this phone have found little support for those running android on it or anything else? sometimes i feel like im the only guy in the united states with a telstra hd2 and everyone else is using the tmo usa one, all the forums talk about the euro hd2 and the tmo usa one

im in the same boat, but with Bell in canada..i use the Telstra HD2 and from the looks of things were just getting the LG with the keyboard and a 3.5in screen..looks awful. im hoping the same with the HD7, just a matter of whether they can be sim unlocked. ill be keeping my eye on it and hoping for the best anyway.

Is it telstra even getting the hd7?

Seems like Telstra will be getting the HD7 exclusively in 2011 similar to what happened with the HD2.
Launch availability will be T-Mobile(US) O2(England/Germany) and SingTel(Singapore) none of which support UMTS/HSDPA 850.

Strange because according to these guys the HD7 will be coming to Telstra in November: http://smarthouse.com.au/Phones/Mobile/X6L9N4K3
And for those of us that bought the Telstra HD2 we may recall the device came factory unlocked. Great for me as I'm using it on Telus in Toronto, Canada.
I looked at our launch line up here as well and our choices are pretty weak. I've read someone confirmed the Dell Venue Pro will work for us on the North American bands. That's my second choice.
But I think the HD7 from Telstra will be good to go. Except we'll be stuck with a Telstra Hub until someone figures out how to flash new roms lol..

You can uninstall the operator's hub, it'll just come back at each hard reset

front facing camera?
is it possible to find someone who can install a front facing camera as well? I would pay who ever could do it, it can be done with the samsung vibrant, it is really disappointing there is no ffc installed
and now im worried once i import the hd7 from telstra will there be roms that i can use to remove the telstra hub and skins? I doubt a hard reset will remove this, we are all venturing into new ground here indeed

there are no skins, and the carrier apps can be uninstalled

According to this article "Unfortunately the elusive HTC HD7 is not available at launch. It’s officially slated to be available exclusively through Telstra next year in 2011. You would be wise to bet the first half of the year."
I honestly believe it will be worth the wait.
Were you able to use your Telstra HD2 on AT&T straight out of the box? I ask this because I could not. It was indeed sim unlocked, but didn't work for me. Granted I only tested it once and then HSPL/Flash to NRG.

When you say "uninstall" I assume then you mean just remove their hub from the homescreen without actually uninstalling their software.

Odd that on the same day 2 different stories would be printed. One saying it's available next month, the other saying next year. Guess we'll know for sure by November if it doesn't actually arrive.
For me personally it worked on the Telus network right out of the box, even before I HSPL'd it. The only hassle was setting up the data and mms manually. But later I found a few custom roms that did that for me.

Review of the HD7 PCWorld AU
"This Telstra-exclusive Windows Phone 7 smartphone will launch in Australia in January 2011."
Anyone have a time machine?

The UK carrier O2 is also adding the HD7 to their line up for Oct. and has quad band GSM:
http://www.3g.co.uk/PR/Oct2010/o2-add-htc-hd7-windows-phone-7-smartphone.html
Based on my previous knowledge of quad band phones it should support the more popular 850/900/1800/1900 bands.. that being said can someone with more knowledge than myself confirm whether this would work similarly to the Telstra version?

Actually flashing a ROM won't work. You can't unlock the SIM by flashing another ROM, you have to get the unlock code regardless.
Most carriers do it for free or you can find a site online that will do it for a charge.
The OS does not effect SIM UNLOCKING so I do not see any change with WP7

The UK carrier O2 is also adding the HD7 to their line up for Oct. and has quad band GSM:

Based on my previous knowledge of quad band phones it should support the more popular 850/900/1800/1900 bands.. that being said can someone with more knowledge than myself confirm whether this would work similarly to the Telstra version?

GSM (2G) is 850/900/1800/1900
UMTS/HSDPA (3G) is more than likely 900/2100 where AT&T is 850/1900

Actually flashing a ROM won't work. You can't unlock the SIM by flashing another ROM, you have to get the unlock code regardless.
Most carriers do it for free or you can find a site online that will do it for a charge.

Do you know any reliable and trusted website? I don't mind paying I just want to be sure the site can do it.
