Htc Hero On 3g In The US ?

Hey, Ive had the Htc Hero for a few weeks, and i was wondering if it was possible to make a hack or something so 3g will work on the us 3g bands. Or will we have to wait until they release a gsm unlocked north American Htc hero. Please get back soon.

You'll have to wait because the HTC Hero only has the 900/2100 bands for 3G while the required bands are 850/1900 in the United States. Sorry.

Im thinking this will show up on Roger's in Canada (uses AT&T Compatible 850/1900) before it actually shows up from AT&T.
Ebay.ca would be the way to go.

I believe it might show up on AT&T sooner than we all think
A version with AT&T 3G bands have already passed the FCC (as well as a version with EvDo bands for Sprint) so it looks like 2 North American carriers are poised for some Hero lovin'. Frankly, I'm ready for either an AT&T Hero or a Sprint Hero as I use both carriers.

according to the htc site, the hero is quad band. I'm able to get a hero from asia and was wondering the same thing.
http://www.htc.com/www/product/hero/specification.html
it should work with at&t and should not lock you into an expensive plan like the iphone if you get it unlocked.

Quad band for GSM, not for HSDPA/WCDMA. Hero will currently work in the US, but Edge is the best you'll get.

My friends there is a US 3G that should hit the streets soon. its called HTC HERO 130(US). the Euro version is Htc Hero 100.

Is this a fact?

Ironically, yes and no!
It is called Hero, but it isn't the same Hero as we have in Europe.
http://newsreleases.sprint.com/phoenix.zhtml?c=220644&p=imageGalleryCategoryDetail&t=MI&MICategoryId=16507&
Spec wise, it is much the same (bands not withstanding), but I far prefer the look of the original Hero.

Thats the Hero 200 not the Hero 130.

Its just a matter of time before we can use it on AT&T Network

Sorry guys, but the HTC Hero is exclusive to Sprint in the United States - http://www.engadget.com/2009/09/03/htc-hero-heading-to-sprint-october-11-for-179-99-no-chin/
Your best bet for a GSM Hero that works on AT&T's 3g is to wait for Rogers(GSM) in Canada to get it. Rogers has non google branded phones like the Magic(MyTouch 3g) and the Dream(G1). Thats just my thought and I could be wrong. But thats your last sign of hope for now. Plus Bell in Canada is getting the Palm Pre, so Rogers having a Hero is a nice fighting power to go against the Pre.
And lets put an end to this.... No European and Asian GSM HTC Hero will not have 3g in the US, only Edge!!! Theirs no hacks or anything that will work... We dont need more threads asking the same questions over and over.
One more thing came to mind. If AT&T and HTC take the SenseUI and put it onto a new android phone and called it something different.... Then you can have your Hero.. I dont see that happening this year. AT&T still has to release the Fortress(Touch Pro2) and Warhawk(Diamond2) still this year.

No one is saying that ATT will get the HERO. We are saying that there will be 850Mhz WDMA version that works on ATT 3G network. It could be very much like you said Rogers Canada. again, there will be HERO 130 that supports ATT 3G network.

does anyone know if the sprint hero will be able to be rooted? i have heard that it will not be possible. please respond thank you.

850 3g ready!

This has been covered in this forum many many times already. You don't have to dig up old threads and then add in some wrong information.
The AT&T 3G capable (850/1900) Hero is carried by Canadian carrier Telus, NOT Rogers. The phone is available from their website directly for CAD$499 + tax, without contract. They don't ship outside Canada, and people have reported that their local Telus stores do not sell them without opening a line. Some said that it could be purchased without contract at BestBuy (in Canada of course).
A friend (who lives in Canada) of mine helped me to get one. It is unbranded, but sim locked to Telus. Unlock code can be purchased on eBay for slightly over 20 bucks. Mine now works with AT&T 3G flawlessly. Note that the difference between this Hero and the European Hero, is in hardware. No ROM flashing will enable 850/1900 for 3G on the European Hero.

BTW, the support of the band 850 alone will not enable a phone to use AT&T 3G network. It requires BOTH 850 and 1900 together.

Yup i'm from toronto and under contract with Rogers. I bought a Telus HTC Hero and unlocked it and it works perfect with Rogers. I took a trip down to NYC and it works on AT&T 3G with no problems.

850/1900 VS. 900/2100 for 3G
I belive that hardware wise - they're not really different.
we already saw in the past hacks (for WM phones) to "enable" more bands.
I believe that HTC blocks part of the bands to complete certification faster (FCC, ETSI etc), and it can be tricked... once we'll have "US 3G" radio, we'll be able to play with it, and compare to "Europenian 3G" radio.

Sorry but this is not the case. Rogers version of Dream and Magic have been out for long time already. Have you heard of any case where people can get European or T-Mobile versions of these phones to work on AT&T 3G?
1. The European Hero does not share the same hardware part number with the Telus Hero. The former is HERO100 and the latter is HERO130. Note that this part number is independent of the ROM installed. Asian Heros (Hong Kong, Taiwan, China etc), all have different ROMs but they are all HERO100.
2. Your "certification theory" is wrong. This type of certification doesn't work that way. Adding another chip to support 2 more bands won't delay the certification by months. Days, at most, if at all.
3. Continued from 2. The HERO100 was never sent to FCC for certification. I have both phones with me right now, and there is no FCC certification logo on the HERO100 hardware or on the box, while the FCC logo is easily spotted on the HERO130.
4. People on the other thread had report dialing problems flashing HERO100 radio rom onto HERO130. The problem went away by flashing a newer HERO100 (but no one knows where it came from) radio rom, although people are still reporting SMS problem with this radio rom on HERO130. This radio has been reported to work perfectly (indeed, a lot reported better reception) on HERO100. If the HERO100 and the HERO130 share the same hardware, the difference should go away by flashing the same rom. The fact that, with the same rom the HERO130 supports 850/1900 for 3G while the HERO100 doesn't, clearly indicate the difference in hardware.
While it is not impossible for cell phone manufacturers modify radio rom to restrict bands that their phones support, this is very uncommon (Can you name those WinMo device that you mentioned?). On the other hand, almost every cell phone model has various verisons of hardware to support different bands in different countries. A chip that supports fewer bands costs less. When there are enough demand to move sales, it is much more profitable to produce a region specific hardware with a cheaper chip than to write code to restrict the functionality of a more expensive chip that supports bands that that region never needs.

Let me get this straight - So TP2 is not a true "world phone"?

I'm a little green when it comes to 3G stuff, but please correct me if I am wrong...
Yes, you can put foreign SIM cards in US TP2's but not get 3G coverage in Europe. On the other hand from what I have read, European TP2's (even the unbranded ones) will not work with 3G is the US.
And if I am wrong... can someone please point me to a TP2 that will work on 3G networks in most of the world?
Or does one have to have two TP2's to enjoy 3G.. one for the US, and one for Europe, etc.?

Where have you heard that a NA TP2 won't work with 3G in EU?
The only limitation I'm aware of is a NA TP2 won't work w/ NA GSM 3G.

Until someone hacks it

I can't remember where I read it. But someone said if you wanted 3G in Europe, better to get a Euro unbranded model.
So perhaps this is under the assumption that it isn't hacked... not sure.
Slightly, off-topic Q but rather than start a new thread.... once a HardSPL is out for both the CDMA and GSM TP2's... will they effectively be "equal" devoces?
I really would like to pick-up a TP2 in the next few days... I like the VZ unit, but it's CDMA and since I travel quite a bit, really prefer and need more of a GSM phone, but don't like the TMO as no 3.5mm jack.

The Verizon unit already has international GSM bands unlocked, AND international (2100MHz 3G). If you've been a Verizon customer for 60 days or more you can call them up and get an unlock code for free and use any SIM card in your phone so you can get a cheap prepaid SIM and not pay the high Verizon roaming costs. There's also a small (I'd say around 25%) chance that the NA 3G bands will be found/unlocked, but at this point who really knows if they are there or not.

Actually the Telus CDMA TP2 supports the European 3G bands but not the American ones becuase technically you will be using it in North America on CDMA and outside America on GSM. So its the other way around

It seems that if you have the Sprint TP2 that it won't register at all on US GSM networks, but comes unlocked by default.
On Verizon (which I have) a simple phone call to support they'll give you the unlock code and you're good to go. I use an Orange (UK) Sim in mine just fine in the US and others in other forums have reported that using US SIM's from TMobile/AT&T work fine also in the US.

I have an unbranded HTC factory TP2, and it works in 3G mode anywhere I take it that has the 3G network... and I travel all over the US/Caribbean and back to EU/UK. Have not found one spot it hasn't worked (inlcduing some of the very obscure Carib countries), and I like the fact that it automatically picks up HS when within range without having to change any settings.
Just have to make sure that your provider gives you a 3G SIM (most of them are these days) and that you have the 3G service enabled on your account in the respective country.
Many people say they can't pick it up yet don't have it on their account, or think that their EU provider will automatically provide it as part of the roaming service... which is not a good assumption to make.

3G in North America? I doubt that. The phone does not support North American 3G bands. Are you sure it was 3G in North America??

Man, this is all confusing... I swear somebody has to come up with an HTML table of what phones work with what and where and stickify it.

Can people just put this to bed already!!!
The Sprint (North America) TP2 is suppossed to be used on CDMA in the US and GSM worldwide, hence the GSM radio is unlocked for outside America GSM use. This is how it comes default. If that is so hard to grasp, then there is no hope for some, sadly.
As for the title, the TP2 is a world phone, it works in the US (and North Ameria) on CDMA and elsewhere unlocked on GSM. That to me is the true definition of a World phone from a U.S CDMA perspective (and especially moreso as this is the CDMA version).
To put it in perspective, a Sprint customer (in this case, moi) gets the best of CDMA in the U.S and when traveling to visit his sister in High Wycombe in the U.K (like i'll be doing this Autumm) gets to pop in a PAYG U.K sim in the same phone and use it while over there. This phone doesn't get any "worldlier" to me than this scenario!!
Is the O.P attempting to specifically define a dual mode CDMA/GSM-unlocked World phone as not world phone because it's locked by default from doing GSM in it's primary market which happens to be CDMA (and in this case Sprint)?
This is not rocket science folks, it really isn't.

Point taken. It's just that with that same Sprint phone (correct me if I am wrong), you can't travel to Canada pop in a Rogers SIM card and get Rogers 3G.
Wouldn't the phone want to swing towards it's CDMA cousin, Telus or Bell?

AT&T 3G runs on 850/1900 GSM, the TP2 supports both of those bands, how would it not work with 3G on AT&T in the US?
T-Mobile runs 3G on 1700/2100 GSM bands, both of which aren't included on the TP2, as far as my research has lead me to believe.

Basically while it may be a quad band GSM phone, it is only a dual band 3G device. It comes in two flavours - UMTS 900+2100 or UMTS 1900+850
The 900/2100 version is far more common than 850/1900

"it Depends"
The US CDMA phone operates in 3 modes.
1 CDMA Only
2 GSM Only
3 'Global' (whatever it can find).
If you have it in Global it will generally take the CDMA local carrier over anything else. However, not always. I've had mine switch to GSM for a bit then go back to CDMA. But mine is Verizon and unlocked so it works everywhere in the US and I also have a UK sim card in it. So I'm a little 'different'.
But, in any case, you can tell the phone which mode to use if you want. All upto you.

(verizon TP2)

here we go again... (tp2 3g na)
"I have an unbranded HTC factory TP2, and it works in 3G mode anywhere I take it that has the 3G network... and I travel all over the US/Caribbean and back to EU/UK. Have not found one spot it hasn't worked (inlcduing some of the very obscure Carib countries), and I like the fact that it automatically picks up HS when within range without having to change any settings."
So, maybe he's wrong. But either way...
You wanna know why this keeps coming up again and again?
(not because we're all dumb and thick headed, which we may very well be)
But,
Because we just have trouble imagining them hardware "band amplifier" hobbling the hardware when it's so much easier to do it somewhere in firmware.
We all know that the less you fiddle with the hardware for multi-region functionality the less you have to fiddle with the production line and fiddling with the production line is the Last Thing a manufacturer wants to do.
Someone even once said that there wasn't room in the Rhodium platform for quad band data support. But now we're expecting the tilt 2 to do just that.
So, all protestations aside, those of us who paid ~700 us clams for this beauty, and who like the kbd layout.
And who have like me (as quite the Early Adopter), forked out for an sx56, sx66, 8135, x7510((quad band data)
Just feel a leetle wee bit of a sense, dare I say it, of Entitlement for the TP2 to be enabled into a fully world wide phone.
So we keep hunting, and digging, and dreaming, and .... posting.....

well here is my two cents i have the original unlocked euro version of the tp2 and all i get in the us it edge. it is really impossible to get 3g in the US (2100) because this version of the phone literally does not have the attena for it. and so that you can see all the different types of tp2s and the technical and physical differences between them here is a link: http://pdadb.net/index.php?m=pdacom...&id3=1792&id4=1829&id5=1766&id6=1989&id7=1751

3g in the USA must be on the 1700 band then, as thats the only gsm band that the euro version doesn't support.
Euro version
GSM850, GSM900, GSM1800, GSM1900, UMTS900, UMTS2100
TMOUS version
GSM850, GSM900, GSM1800, GSM1900, UMTS1700, UMTS2100

Anyone know of a good site to order a prepaid SIM card? I plan on using my VZW TP2 in Spain and France. I was also wondering if I should or could disable data and use my TP2 with Garmin XT so I don't get nailed for data usage. Your thoughts would be appreciated...

[Q] Is it possible to Flash G2's 3G Radio, an set it to work on 900/2100 mhz??

Well, it's just as the title of this thread says... I have a Tmobile's G2 (A.K.A. HTC Vision), which its 3g default bands are under 1700 / 2100. Here on my country, all the providers have their 3g services on 900 / 2100.... soo... Is it possible to Flash T-mobile G2's Radio, an set it to work on 3g 900/2100 mhz, so I can use the phone on 3G, instead of that annoying and extremely slow EDGE??
Or, is there a Custom ROM that has these settings on it? (I mean, a rom that automatically turns the 3g band to 900 instead of 1700)
Thanx.

No you can't, the radio bands are set in hardware (e.g. the physical antennae in the phone), not just in the radio software.

Why would you need to, the phone would use the 2100 band for it's 3G in your country? I took mine to Russia and it worked fine.

I don't think it's that simple. I only get edge on my T-mobile G2 using the Rogers network.

Rogers doesnt use 1700 or 2100 so that is to be expected. The original posters country has a 2100 3G, I would suspect he just isn't in a coverage area.

I don't think it works like that, I think it needs both bands to work. If it was that simple then surely they wouldn't bother making different phones for different markets (e.g. T-Mobile US vs Europe/Asia)

That may be...I'm only speaking of my experience in Russia, they have 2100 only 3G and mine worked without the second band.

Just to add, T-Mobile US use the 1700 MHz band for the uplink, and 2100 MHz for the downlink. So presumably the phones (i.e. G2, as opposed to the Desire Z) are physically setup like that too.

Oh I thought Rogers uses 2100. Either way, no worky.... sad.
Sent from my HTC Vision using XDA app.

Ah, I think I'm following you, because Russia exclusively uses 2100 for up and down my phone worked, but since his county has a seperate uplink and a downlink band it won't?

Yeah I think that's it. I don't know *that* much about this myself, just picked up on a few discussions about the G2/DZ on here over time.
Have a look at this - http://en.wikipedia.org/wiki/UMTS_frequency_bands
I think the "problem" is that the G2 uses exclusively "Band IV" for 3G (i.e. 1700/2100 split), but somewhere like the OP's Dominican Republic uses Band VIII (900).
What the OP needs is a Desire Z, which operates on Band I (2100) and Band VIII (900).
Russia appears to use Band I (2100) as well. Maybe a G2 can partially work there then ?
Rogers uses something else, Band II (1900) and Band V (850).
As I say, I'm don't know that much about this myself, so if anyone else can help clarify/confirm/deny, then that'd be great.

Much appreciated.
Sent from my HTC Vision using XDA app.

Via Google, I dug up another interesting piece of info.
Although it's not on HTC's official spec list on their site, on T-Mobile's support pages it says that the G2 does Band I as well. Which would explain how it would have worked in Russia. That's not going to help the OP's problem though.

Wow mega confusing, but you helped clear it up, thanks!!
Mine worked very well in Moscow, I was pleasantly suprised, it was kind of a bonus to be able to get on the web, I wasn't expecting much.

I don't understand why the manufactures don't provide phones with penta-band 3G support like the Nokia N8. Maximize profit when producing 2-3 same phones with different frequencies maybe? I mean quad-band GSM has been supported for pretty much all of the current phones, why not 3G bands as well?

Has anyone tried this option?
bring up the dial pad and dial
*#*#info#*#* (aka *#*#4636#*#*)
press "Phone Info"
you'll get the screen with the imei, phone no, network and a button that says "Run Ping Test" at the top
press your "menu" button
when the menu pops up, it'll have 6 options, select radio band, view sim address book, view fixed dialling numbers, view service dialling numbers, get PDP list, and More.
Choose the first one "Select Radio Band" then select the appropriate band.
Not sure if it helps in this situation, but I found it in a thread about gaining 3G in Europe on the N1

hey bro.. I read from one topic in TMo's official G2 forum that the G2 will work on a country with only a UMTS band of 2100 both for up and down (the answer is from TMo employee, an engineer)... hope you'll be enlightened. I bought an unlocked G2 and I researched extensively before purchase. Im from the Philippines which only supports the 2100 band for 3G. I Know and Im 100% positive that the phone will support the 3G band here in my country. cant wait for my G2 (arriving tomorrow)
btw... coverage is vital. if the 3G signal is weak or non-existent in your area, you'll be switched to edge for data on your phone (naturally).. good luck
sorry.. cant post the link. would've loved to have posted it.

That's the Band I thing that I was talking about, that T-Mo shows on their spec sheets (but HTC doesn't seem to list, for some reason).

I think the G2 will do 3G if any one of the two bands are supported by the country. Correct me if Im wrong

There is nowhere in the world that uses 2100 in both directions. Band 1 is 1900 UP, 2100 DOWN.
In all cases, your phone must be able to upload on the frequencies that the towers listen on, and download on the frequencies that the towers transmit on.
I.e., north america vision transmits on 1700 or 1900, receives on 2100.

All Band Phone?

A question came up on the us forum for Defy about the different software builds until finally a Moto-mod came in with this. It's intriguing in that apparently the Defy has all band capability, but the software build limits the choice. Here's the quote:
"Each Blur Version for the Defy is all Carrier and Regional Specific like for instance For US T-Mobile Customers its 3.6.19.0 however for UK T-Mobile Users I think the latest version is 2.51 Other parts of europe are using 2.34 without MotoBlur and so on and so fourth, the main difference is Carrier installed apps and the confusing part, from what i've expierenced with the phone, Its the first phone i've ever seen with a software controlled universal radio supporting all bands, however its software tells it which band to use, for instance if you 2.21 and 2.51 UK versions are using UMTS 900/2100 where US's 3.6.190 is using AWS 1700/2100. there are ways if you look to obtain version 2.51.1 however this isn't the place to look on instructions on how to do it because its against the forum rules, is unsupported and with 2.51 if for whatever reason you wanted to downgrade you couldn't unfortunatly."

WHAT.
Software defined radio?
If this is for real the hackers SHOULD REALLY HAVE A FIELD DAY with this phone.
It's a shame they're too busy with the Samsungs and HTCs of the world..

There's quite a difference between true software defined radio (most radios these days are sort of there, as they are most commonly some embedded chip with custom firmware but nothing like a Linux kernel) and being able to switch frequencies to be used

I'm not an expert, but the basic thrust of this was that all Defy phones are identical and capable of all frequencies, but the firmware defines which can be used. Therefore it seems -- to this novice mind -- that change the firmware change the phone.
The other, related issue is the frustration of some Euro phone owners who really know nothing about differences in 3G frequencies. buy a phone and presume they can use them in the US (as one can with an iPhone). Those of us who prowl these forums are basically smart enough to know that before you buy a phone we have to be sure we can actually use it -- but 90% of buyers buy a phone presuming they can.

Okay well can someone on the forum test this out? You'd need the ability to try and access both sets of frequencies.
Example: You're in Australia and you have a Defy from Telstra which you've also unlocked. Your stock firmware supports 850/AWS/2100. You should be able to get an 850 MHz signal from Telstra's NextG network. Now, if you put in an Optus SIM and visit an area with 900 MHz 3G coverage but not 2100, you'll find the phone drops to EDGE or gets no signal.
So at this point, take a nandroid backup, and flash a 900/2100 firmware or replace the radio files with ones from such a firmware. Now repeat the same test... does it successfully register on Optus at 900 MHz?

Radio issues...
Strictly on the band issue, I don't think they are that apart. A good radio would be able to handle it without being full SDR.
I agree partly on the point that these radios are somehow SDR for they do change the frequencie ranges by changing firmware.
A full SDR would be able to change even to CDMA or something else, not only the band!
If you want to challenge someone for doing something about it, ask for a full tri-band version of the Defy radio! (That I would ask for too!)
I intend to use my Defy originally 850/1900 over a 2100 network.
Well that's is my humble guess.

Interesting, as if you go into the INFO menu and select "set preferred network type" one choice (which it will not allow) is CDMA. But it's there.

Which version of the Defy is UMTS 850/1900? I thought there was only 850/1700/2100 and 900/2100.
Also, pretty much all Androids have CDMA as a listed option, not because they're compatible, but because it's a testing menu that was designed to be applicable to a wide variety of phones.

Which defy to buy?

I'm considering purchasing the Defy. (completely in love with the idea of a waterproof phone)
I live in US and have AT&T. Seen topics about the T-Mobile version working on AT&T's 3G bands.
I plan on purchasing one from eBay and my question is, should I get the american "T-Mobile" version or should I get a European version. Which one has more/better roms available? Does the European version work on AT&T 3G? I'm a fan of the all black UK version as well. Are there any other hardware differences besides color of the phone?
Thanks alot! Hope to be visiting these defy forums more often!

Ok, if you buy the American (T-Mo?) you should be able to use it on AT&T 3G through the 850 freq, and of course, on T-Mo.
http://androidforums.com/t/217819-t-mo-motorola-defy-working-t-3g-850-band-only.html
You will also be able to use it on the most common international freq, 2100. Looked at the Euro spec phone on the Moto site and they do not appear to be able to work on any USA 3G.
The USA T-Mo branded phone seems to be far less likely to developed the "failed earpiece", if that is even still an issue with current production.
Also, there is a thread with people complaining that the all black phone is structurally "cheaper". Maybe it's an appearance thing. Of course, the T-mo branded phone comes with wifi calling which you cannot use on AT&T... but should you ever switch...

Awesome! Thank you very much for the information.

Remember, I'm only passing on info on the 850 band but have never tried myself.
