There is a way to change the HSPA/WCDMA 900/2100MHz to 850/1900MHz or to quad band HSPA/WCDMA?
Regards,
Giacomitti.
Yes, sell your European Hero (HERO100) and buy a North American (HERO130) Hero.
No, the difference lies in the hardware, no ROM swapping can change that. Note that HTC Canada website is incorrect. The North American Hero supports only 850/1900 for 3G, 900/2100 does NOT work on the the North American Hero.
The Dual-Mode crap listed on HTC Canada website is complete BS. It contradicts with the specification of the phone in the user manual of the HERO130 (can also be found on HTC Canada website), which says that the phone supports only 850/1900. Furthermore, the FCC test report of this phone also shows that this phone only support 850/1900 for 3G. I can confirm this as I have a HERO130 and I am currently in Hong Kong, where all carriers use 2100 Mhz for 3G. I have tested the phone with various sim cards, and the HERO130 cannot connect to their 3G networks (but the Asian/European Hero, HERO100, can connect without problem).
Hi. So I finally decided to purchase my first Android OS based phone. At the moment, the two phones available to me and in my price range (used, $200 and under,) are the Samsung I5700 Galaxy Spica and HTC Magic (plus a Hero I found for very cheap.)
Custom ROMs aren't too important to me, the stock apps (browser, calender, SMS,) built into Android easily meet my needs, but the Spica's spec sheet is very nice. Obviously the Magic/Hero is fairly dated now, so it doesn't really match up. But the Spica's 3G radio is not compatible with Canadian providers. I need a phone that I can switch from network to network here in Canada. Two to 3 years plans are out of my means currently, plus I don't really like contracts.
I guess what I'm really asking for is: is the Spica worth potentially paying more money for - is its support for Divx, its form factor, its display and its beefier CPU worth an extra $5 a month? Or should I just settle for a Magic/Hero?
EDIT: According to GSM Arena there's a NA version that supports, HSDPA 850 / 1900. Can I verify what bands the Spica supports by checking a menu in Android?
I have a non-NA Spica in Canada. The only networks it doesn't work for are Windmobile and Mobilicity because they use 1700MHz.
Right. And the other UTMS networks available all operate on 850/1900. So if you're using the non-NA version, which has HSDPA 900/2100, you wouldn't be able to use any 3G network in Canada? Please correct me if I'm wrong, I'm just learning this stuff at the moment.
Personally, I'm going to go with either Koodo or Solo, because at the moment, because of where I'm at, they have the best available prepaid plan.
There are 2 versions of the Spica and 3 of the Magic -
Magic: Rogers, T-Mobile USA (myTouch 3G), international
Spica: Rogers, international
As it would suggest, the Rogers versions of each of these phones works on the Rogers 3G network, as well as that of Telus, Bell and now Sasktel, as well as all of their subsidiaries, such as Solo, Koodo, Virgin, Fido, etc.
The T-Mobile USA myTouch will work with Wind Mobile, Videotron and Moblicity, providing you're in one of their coverage areas. Otherwise it will work with Rogers (and Fido) on their 2G network.
The international (anywhere but North America) versions of these phones won't work on any 3G network in Canada, so you can use only Rogers (and Fido) on 2G.
Similarly, there are 3 versions of the Hero, a Telus one that will work with Rogers, Telus and Bell; an international one that will work with Rogers on 2G and a Sprint one (that looks cooler too) that will only work with Sprint in the US, and doesn't take a SIM card.
Hope this helps
Hi there guys! Now that the phones are finally shipping, can anyone please test the real band compatibility? I want to buy an unlocked G2 and use it here in Italy, but only if I can get at least a fully working 3G connection.
Please fellas, I badly need this info..
Thanks

No such luck chief. The only 3G band on the G2 is AWS. It will only work on carriers like T-Mobile (USA), and Wind (Canada).
The stock Desire Z, however, has HSDPA 900 / 2100 and should work in most non-US countries on 3G, but check your carriers bands first. The downside, Desire Z has 1.5 GB storage, the G2 has 4 GB.

Unfortunately I think you are going to be disappointed. I posted a buzz about this a while back. You can look at page 3 of the test report in the FCC submission. The nutshell summary is that the device will only support Band IV for 3G, or in other words T-Mo US' UMTS 1700. This is unfortunate since I used my unlocked G1 quite a lot overseas, thanks to its UMTS 900/2100.
You'll probably have to go with a Desire Z if you want this device with European radios.
Can't believe it's for real...I mean, the 2-year-old G1 does that...and what about people working overseas?
That's a MAJOR fault from T-Mobile, and it's totally weird to say the least.

Perhaps tmo figures that frequent int'l travelers are a small enough percentage of their userbase that omitting the Band I poweramp was worth the cost savings?
Oh, it gets better. I only paid attention to the UMTS bands when I read the report, assuming that any modern smartphone would be a quad-band GSM device. Turns out the G2 is only GSM 850/1900, which means this device is truly unusable in Europe and Asia.
Wait a minute, what GSM bands are used in Asia?
The HTC site says otherwise : http://www.htc.com/us/products/t-mobile-g2#tech-specs
According to T-Mobile and HTC sites specs, the phone is GSM quad band (850, 900, 1800, 1900).
The HTC site says "UMTS: Yes"

Europe and Asia are GSM 900/1800, generally. What is interesting is that the HTC page claims the G2 is quadband, but the FCC testing documents don't show any 900/1800 data at all. The phone cannot legally operate in the U.S. in that band unless testing data has been submitted to the FCC. I'm wondering if HTC marketing just c&p from the Desire Z specs and forgot to edit the GSM infos. We'll see soon enough I suppose.
it doesn't make sense why they would release a phone that wasnt quad band. it must be a mistake. it is like power seats on a luxury car. it's just there lol.
So a unlocked G2 could be used on WINDs network here in Canada (because they use the same frequency), can some one confirm this please

Wind uses AWS (UMTS Band IV)... So, yes. But if they do not have HSPA+ enhancements you won't get the famed and promised super speed. The phone should be able to be used on USA (T-Mobile, Cincinnati Bell Wireless), Canada (WIND Mobile, Mobilicity, Videotron)
Based on the G1 test reports...
... the bands listed in the FCC test reports are not at all definitive.
I pulled the FCC exhibits for the G1 and they listed:
GSM 850
GSM 1900
WCDMA Band IV
(plus 802.11 etc)
In other words, no Band I.
However, I've been successfully using my G1 on 3G in both Europe and Asia for over a year now, so it actually has Band I.
I suspect the FCC tests only cover the frequencies that the device is going to be used on *in the US*. Frequencies the device may or may not be capable of using outside the US just aren't relevant.
That being said, the more significant detail is that the T-mobile site lists the G2 as only having Band IV, even though it lists the Vibrant as having Bands I and IV. Looking at other phones, it seems that T-mobile isn't terribly consistent in how they list their frequencies, but that's a (relatively) slim thread to hang onto.

It is quad-band -- for GSM -- as all (most?) modern non-CDMA phones (and some of those) are. But the OP question is about 3G.

I wouldn't put it past T-mo to have just messed up the detail.
I suppose the easiest way to determine would be for someone with an unlocked G2 (or even a locked unit) to take it to Europe or Asia and see if the system status shows UMTS signal or not.
Unlocked G2 Australian user
Hey Guys,
I actually received my G2 a few days ago. Yesterday i purchased an unlock code and entered this in to the phone which it advised was accepted.
The device then rebooted, however once the system loaded i noticed my signal bar had an "x" through it.
Browsed to Network Operators and tried selecting to search for networks and also to select automatically. Both of these selections returned an error "error searching for network" or every second try it would say "unable to connect to network".
I tried a factory reset of my phone but still the same issue.
I tried dialing *#*#4636#*#* which opens a testing screen. I noticed on this screen i can see i have a signal of -85 dBm which is similar to on my galaxy s.
Tried playing with the settings on this screen, i had the option to select network band to which i alternated between all options including auto and AUS, AUS2.
I can confirm this is a Vodafone simcard and it works perfectly in other phones.
I tried a Telstra, 3 and a friends Vodafone simacard all of which produced the same error.
I noticed there are several Australian sites selling unlocked Tmobile G2's.
At this point i would like to try flashing the stock rom on again however i am not sure on the button combo to access the recovery screen.
Last thing to note is yes i have spoke with Vodafone, HTC AU and HTC US, none of the techs were able to help me. =(

What was the network type when you saw the -85 dBm signal?

Would a G2 work on Softbank (Japanese Carrier) They use the 2100 band IV I believe. I know my T-Mobile Nexus One worked fine on there 3G.
I could care less if the HSPA+ worked just 3G would be fine.

Band IV is commonly referred to as AWS 1700. From the gsmworld entry, it looks like Softbank is running on Band I ("UMTS 2100"). The G1 and Nexus One both had UMTS 900 & UMTS 2100 (the global bands) in addition to T-Mo specific AWS 1700. We're trying to determine if the G2 also has 900&2100 radios, but right now it's not looking very good.
Question for the collective wisdom of the group:
I bought an unlocked T-Mobile HTC G2 off of ebay thinking it was the same as a regular Desire Z. Phone is great, but 3G does not work in my home country (Honduras). Is there anyway to change the data frequency on the phone?
Thanks in advance

No, not possible.
Sent from my T-Mobile G2 using XDA App
NAM version of Desire Z
Someone told me that I need the NAM Desire Z (850mhz) to be able to use with my local network...Am i really stuck with Edge with my T-mobile G2?

Yes. The G2 and the DZ use different bands for data, so you will not be able to get 3G or 4G from it.

Unfortunatly yes, you are stuck if you keep the G2, best bet sell it an get a HTC A7275 Desire Z NAM, this model supports (850mhz). This is the only model Desire Z that supports this frequency. It has to ba a A7275 model. Bell Canada sell this model and some other online electrionc vendors.
There are AT LEAST THREE different variations on the VISION hardware, supporting different frequency sets. The AWS version debranded by tmobile, is capable of upload on 1700 (used in US and Canada) or 1900 (used in Europe) MHz, download on 2100.
For info, since this comes up a lot, I have updated the Wiki with the information about which radio bands are supported by which Vision model - http://forum.xda-developers.com/wiki/index.php?title=HTC_Vision#Radio_Bands
As other have indicated, you are stuck on EDGE. The MHz compatibility is a function of the hardware, and therefore can't be changed. Always research the heck out of the device before buying anything that is unlocked or otherwise not from your carrier.
If your wireless provider uses "standard" north american frequencies like AT&T USA, Bell Mobility Canada, and Rogers Wireless Canada, you need the Desire Z p/n: 99HLW020. Phones that are p/n: 99HLW021 are T-Mobile USA only.

"Standard"? It would help if there was such a thing. In most of Europe and in Japan, they only use one network type and frequency (instead of mish-moshing GSM and CDMA and different frequencies). As long as your phone is SIM unlocked, you can use your device on any carrier. That's how it should be.

How do those 3 together make it standard? There are 3 providers using UMTS on GSM and PCS (which you've listed), there are more than 3 using AWS.... tmobile, globalive, mobilicity, and videotron running now... and more coming soon... as well, ALL of the providers you've mentioned OWN AWS spectrum, and at least ATT is apparently planning on using it.... (robelus just bought a bunch of it up to block out competition... the bastards.)
So seems to me that AWS is more "standard" than GSM or PCS spectrum.

Yeah, I don't know if calling it the standard for North American frequencies is completely right (though I believe in terms of numbers of users/towers instead of number of providers, it actually might be but I'd have to go research to be sure---most manufactures refer to their North American versions of phones as using these frequencies as well). I would say however, it is pretty much the standard for the Americas. Almost all of Central and South American use 850/1900 as well. AWS is limited to only the the US and Canada (I believe).
If I understood right at least some DVPs have radios capable of using both T-Mobile US's 3G network and European 3G networks. Has anyone tried this? Are we sure that all DVPs have the same radios? Or do the European ones have the US frequencies disabled or something?
Thanks in advance for any info,
Tom
The US ones have AWS for TMOUS, and European 900/2100.
Whether they will actually provision correctly and be usable w/ 3G services in non-US locales is anyone's guess. The US DVP has only just recently been unlockable and I don't think we have had any reports of actual int'l roaming success yet.
I think its been mentioned in the unlocking thread that people have used it in Europe and from the listing of the DVP I've seen the specs indicate its has the exact frequencies as the US one. I would expect it to work, unless Dell has done something really screwy (but thats not impossible) but hopefully someone can confirm for sure.
People are claiming that European DVPs have AWS 3G support? I don't think so.
Although it is conceivable that it's there and simply unadvertised, I believe non-US DVPs have 900/2100 *only*.
US DVPs have 900/2100 *and* AWS.

Actually I was referring to people with US handsets being used in Europe, not the other way round. And its possible the Euro version is hte same as the US one, looking at a video of a DVP released in India it shows the same frequencies as the US one, and Clove also lists the same 3G frequencies so I would lean towards all DVP's bring usable in Europe and the US.
With today's big news, what's the point?
Once AT&T shuts off AWS UMTS in a year or so we are all gonna be left with paperweights anyway.

NAY, I SAY THEE NAY!!!!!!!! Could be right though, but I was planning on ditching the DVP for a penta band Nokia so I guess I'll be ok - save for being on at&t!
3G works here
They are saying it will take "several years" to transition T-Mobile users. Lets hope the regulators see sense and block it in any case...
So I have a European DVP now. Anyone know of an app that will tell me the radio frequencies it supports? The System Info one doesn't seem to.
It supports 900 and 2100.
How did you find that out? The box says UMTS 2100/1700/900.
The European box says the phone inside supports 1700?
my US T-mobile DVP (unlocked) works fine on tmobile Germany and I get about 3000k download 2500k upload. I am in a fairly bad region for network speeds. But I have hit upwards of 7000k download in some bigger cities.
