3G Networks hardware LOCKING to each carrier by HTC

Among those of you with a deap knowledge of the inner working of HTC phone for 3G networks.
Is HTC doing something to phones for each carrier to lock the phone to a specific carriers 3G network and no other.
I'm asking because I was talking with a freind of mine who was given a HD2 as a part of a promotion for use on AT&T 3G network (850/2100). He uses T-Mobile and tried to get it to work with his T-Mobile SIM with no success. He also told me he had a conversation with someone from HTC that told him that he would no beable to get his HD2 to work on T-Mobile because the hardware will not work with T-Mobiles 3G network (1700/2100).
If this is the case does anyone know if it changable, is it a Firmware issue that can be changed or is it like hard wired physically?
Then the question is if we are buying these phone, some through contracts others outright, do we want to told whos service we have to use!!
Lets have some good discussion...

there are billions of threads on this.
3g is radio/hardware dependent. he'll unfortunately be stuck on EDGE.

He will have no issues using the phone with T-mobile usa. He will not get 3G because of the bands. He will just have edge. But calls, mms, text, email, and internet will all function properly.

Clarify this please
I bought my HTC HD2 in USA (unlocked) and here in Peru, where I live, I cannot get it to work with 3G. If I lived in USA, is there a way to know with what carrier I would get 3G ?

So you are on Claro in Peru?
For 3G you need a phone with 3G 1900 support. If it is the T-Mobile version, that would have 3G on 1700/2100 bands which would be no good. If you got an AT&T handset (850/1900) it would work for 3G for you.
You need to understand what 3G support your version of the phone has. For example mine (Telstra Australia) is 850/2100 - which would not be able to pick up 3G in your network - however it works excellent with Telstra (850) in Australia and currently working well with StarHub (2100) in Singapore.
Your phone is quad band - but that is GSM quadband not 3G - it is 3G dual band and that is what is important for your connection.

Hi tallmantim ....
Thanks for your response. Yeah, today I did my homework and found that my HD2 has UMTS (HSDPA) 900 - 2100 bands, a fact that is not good because Claro and Movistar in Peru operated the 850 - 1900 bands for 3G.
Question: is there a HD2 version with 850 - 1900 band ????

No, but the Telstra HD2 will pick up the 850MHz signals where they exist. There is no HD2 with the 1900MHz UMTS band at the moment

Would you mind pointing me in the direction of those BILLIONS of threads.
I've done searchs on hardware dependents, radio/hardware dependents, 3G radio.
There are so many way that is topic could be listed.
I'm finding nothing but my thread now just as before.

Erm, so AT&T gives a phone, for promotion of their service, and at the same time they should allow you to use another network? You've got too much hope there...

x10i on Rogers Network?

Hi,
I bought an x10 from 3 hong kong, fully unlocked. I brought it back to Canada and there's no 3G! I checked all the frequencies and should be all compatible, entered rogers APNs and still no 3G.
Is it possible to get the x10 to work on 3G on rogers?

No unfortunately. The X10 you got from Hong Kong is the international version and it does NOT have the correct 3G bands for Canada/US. You do get quad band GSM but you can only get EDGE. You would need the American version of the X10 in order to get 3G.

Yeah, tough luck. I'm still confused as why AT&T and T-mobile has different 3G bands. Rogers and AT&T use WCDMA 1900 MHz bands while T-mobile and what feels like the rest of the world (just kidding, but at least Europe too) uses WCDMA 2100.
Stop me if I'm way out of my league but my question is WHY?
And isn't it possible to just buy the phone from Rogers directly, cash?

Yea you can buy the phone from Rogers directly with cash but it is still locked. You need to get it unlocked before using it on another carrier.

Why do you need it unlocked if in Canada Rogers is the only one using that frequency?

that's the problem. i can't use rogers phones since i travel a lot. i have to buy a world phone of some sort.
I heard you can root your phone and change the frequencies. is that possible?

I was assuming Flamso might need it for AT&T or some other carrier. Also, it's not just Rogers that uses the frequence. We do have Telus and Bell now. Buy an X10, get it unlocked and use it on Telus or Bell.

Telus and Bell aren't CDMA?
I know Fido and Rogers are the same.

You shouldnt have a tough time selling that one here. Doesnt it support the aws band that wind mobile runs on? AWS 1700 i think

what color you have? I have a BNIB unlocked X10i white wanting to trade for a X10 locked to rogers
email me if interested

i have the luster white x10i from one of the ebay seller in HK, and it works with T-mobile USA 3G network. UMTS band is 900/1700/2100. Rogers are using 800/850/1900/2100. I dont think you could change the frequency as it is part of the hardware.

Is there a way you can boost edge speed? i can't load facebook or weather with edge. it always times

Cheapest Canadian X10 unlock: http://www.mobileincanada.com/?l=en&u=all&coupon=facebook $5 CAD
T-Mo US and AT&T use different frequencies because spectrum is regulated. Whoever has the deeper pockets can buy more of it.
T-Mobile & Wind Mobile use the same 3G frequency (Band IV 1,700 Mhz) whereas Rogers and AT&T use Band V 850 Mhz.
Telus and Bell Mobility are also now HSPA so you can use unlocked Rogers 3G devices on their network too.
Bell has a tool on their website where you enter in your IMEI and it'll tell you if it's compatible: http://www.bell.ca/support/PrsCSrvWls_GettingStartedGuide.page#4

the Hong Kong X10i version will support T-mobile USA 3G network. the UMTS bandwidth is 1/4/8 which is 900/1700/2100. I got my luster white from hong kong ebay seller, and it works with T-mobile USA 3G network. For X10a (american version) the UMTS bandwidth is 800/850/1900/2100.

so that's why they have x10i and x10a
hardware difference for the 3G network to link with.
x10a is designed for north america
x10i can link on at&t's 3G just because it match

Just sign up with WIND mobile and enjoy because the X10i is compatible with the AWS band (same for T-Mobile down south). But if you are out of their coverage area then there won't be any 3G service (falls back to GSM + EDGE).
The X10a from Rogers will work with Telus and Bell HSPA 3G networks once you have it unlocked.

it does not matter what kind of x10 firmware you have. if your phone is originally a x10a, it has att 3g bands that works with rogers. if you flashed it with x10i firmware, you can still use the 3g because flashing the firmware does not change the bands.
x10i will work with rogers but you only get edge aka 2g.

[Q] MT3GS on Rogers

I just bought a My Touch 3G Slide on eBay. I got it unlocked in an hour using cellunlock.net for $10 and got it all setup. However, now I'm noticing that it never goes into 3G, just EDGE.
I searched to find if it could even work with Rogers' 3G network and I'm even more confused. So does it work with Rogers' 3G?
I've also seen posts that it works on HSPA. I've used the APNs for Rogers' HSPA and still I'm getting just EDGE. Do I have to update my radio, use CM6 or something?
Sorry, I'm new to the MT3GS. I have a MT3G/Magic and I thought the new one would be pretty much the same except with a keyboard.

I *think* that Roger's uses the AT&T bands for 3G, not T-Mobile. Sorry.

thats correct, Att and Rodgers uses the 1900mhz band and the mt3gs only has the 1700 NA band and the 850/2100mhz EU bands

That sucks. So it won't work on HSPA either then? I though Rogers offers one of those USB modems that works on 2100MHz HSPDA. Will that work with the MT3GS?

It has the 2100mhz band, but that is so you can have 3G when you go to europe. Rogers only broadcasts 1900mhz in CA.

Damn. Oh well, my wife won't know the difference between EDGE and 3G anyway. Thanks.

sorry i don't belong in this forum but how do you guys explain the g1 having 3g then its a tmobile phone does it have a att frequency for no reason?

Rogers actually sold G1s so they probably got their own version that will work on their network.

unlocked g1's from the US work on rogers network.

Beats me. The myTouch 3G Slide I got from the US works too just not on 3G but on Edge.

OK, I finally get that the frequency band is a hardware thing and that Rogers and T-Mobile use different bands.
http://en.wikipedia.org/wiki/UMTS_frequency_bands
So is it possible to change the actual cell phone radio chip and write a ROM that will work with it? I realize it's crazy, but with all the Android development going on, you'd think someone would have tired to get some device that only worked with T-Mobile to work on At&t.

Desire Hd work in canada?

Does anyone know if there will be desire hd 3g compatibable with at&t , rogers or fido , bell , telus ?

i want to know too

No news about it as of now. You can operate the phone on GSM networks in Canada, but you wont have 3G, only Edge.
On the other hand, the Z will be available on Bell, so you never know.

Yes, 3G will work in Canada.
3G 850/2100, 3G 850/1900, 3G 1700

There you go:

and CDMA coverage map here (just for fun):
http://www.cdg.org/worldwide/index.asp?h_area=0#list

There are some reports like this one around. And considering that the european Desire and Desire HD support the same networks, I wouldn't be so sure. Also, from what I understand not all carriers in Canada support the same network frequencies.

Will the UK version work in Canada?

Hey guys,
Looking at pre-ordering the unlocked version of the DVP from Clove but I'm not sure whether it is going to work in Canada =/.
I've looked at all the Canadian cell phone providers (Telus, Fido, Bell, Rogers) and it doesn't seem like they are compatible with the 3G band on the Dell Venue Pro (900/2100).
Canadian providers seem to require 850/1900 or 1700.
So uh...is it worth buying the phone? Anyone think it will work?
Does the phone need to be 3G compatible to work? (Telus seems to say that your phone NEEDS to be 3G+ compatible).
Thanks,
-Sean

is 3G necessary for smartphones?
I've never had a smartphone before. right now I'm just using an old flip phone.
Would the phone need to have 3G in order for me to bring it to a carrier and add a sim card + plan?

Yea, 3G would be pretty much a necessity, as the next best available connection you would get is edge, which is much slower.

For $989 this site claims to have a Telstra NextG compatible version up for grabs:
http://www.mobicity.com.au/dell-venue-pro.html
I have been using a Telstra HD2 on Telus which gives me 3G+ for a while so I would assume this one would also work. But then again I could be wrong as the bands don't look right..

So it does work if i only use for 2G cell phone service with Fido (no internet), right?
I can use WIFI only.

no your wroung,
you need 850/1900 UMTS/HSPA if you want to use rogers, fido, bell, telus, virgin, koodo, on 3g
you need 850/1900 GSM if you want to use rogers/fido with no 3g
if you want to use wind mobile you need 1700/2100 UMTS/HSPA (same as t-mobile)
