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...

yea my friend my phone is , and i am here with t mobile suffering from same problem like u , i bought that phone which is compatible with Asia , not here in usa
is there way to exchange??
mine is
Network HSPA/WCDMA:
900/2100 MHz
Up to 2 Mbps upload and 7.2 Mbps download speeds
Quad-band GSM/GPRS/EDGE:
850/900/1800/1900 MHz
(Band frequency, HSPA availability, and data speed are
operator dependen)

exchange your phone for cash
exchange that cash for a phone that supports the correct bands.
I'm goin to buy T-Mobile Unlocked HTC HD2 I just wondered if it will work in Israel even though its T-Mobile branded and unlocked
Our network band same as Europe
if that help i got SE W760i and it say on the screen signal "H"
You would have to know exactly what bands your carrier uses (there's several in use in Europe too), but even then the US T-Mobile HD2 probably won't get 3G service where you are, I believe that this is the only country that uses those specific bands for 3G. You could use the phone in your country, but it would only get EDGE speeds.
You would be better off getting the Euro version of the HD2.
after some research i found out that my operator uses this bands 850/2100
and in T-Mobile specs it says
Band (frequency): 850 MHz;900 MHz;1800 MHz;1900 MHz;UMTS: Band I (2100);UMTS: Band IV (AWS);UMTS: Band IV (1700/2100)
and another question if i wont 3g reception i get the "H" would it matter alot or only abit that i wouldnt be able to go through internet and stuff
Bump
Hello again i talked to my operator they said that the phone will work on HSPDA on 2100 or GSM 850
so which of the bands got the 3g on it
Thx
I bought this HTC Aria from USA and use it at my country (Indonesia) But unfortunately the signal is capped to search only gprs or edge, cannot hooked to 3G or hsdpa network..
I also have the asian market Aria, that works perfect in "wcdma only" netwotk. It don't have at&t logo on the upper right screen.
Question is how to make this at&t Aria working on my country wcdma network, bcoz I think that hardware already supported.. I just don't know how to hack it
I believe that its all about software or radio file or something like that , so I put my question here in this sub thread.. So sorry if I do a wrong post.

I think it is more a frequency issue than a lock issue. This is a world phone and no frequencies are locked. But if your carrier doesn't use the same 3G frequencies, it will not work on 3G. The 3G frequencies for the Aria are 850mhz and 1900mhz. Your carrier is probably using 900mhz and 2100mhz for 3G. Your only fix (if this is your issue) is to either buy another phone or change carriers.
Not to threadjack, but do any US carriers use the [apparenlty] more common 900/2100mhz for 3G?

Nope. Neither AT&T or T-Mobile use 900/2100 for their 3G frequencies. AT&T uses 850/1900 and T-Mobile uses 1700(AWS).
The Aria should work
HSPA/UMTS/EDGE/GPRS/GSM; Dual Mode UMTS/HSDPA/HSUPA (1900/850MHZ) & GSM/GPRS/EDGE (Quad band 850/900/1800/1900MHZ); HSDPA/UMTS (3GPP Release 5 Compliant; 7.2 Mbps Enabled) EGPRS Functionality

It's supposed to be a quad band.
No the HTC aria is not quadband for 3g or hsdpa. Basically there is a US versiont the 850/1900 . In Taiwan they released another version with the 900/2100. So if where you live doesn't have a place that uses the 850/1900 your basically stuck w/ 2g speeds.
Hi,
I bought MyTouch 4g from US and unlock it. Now, I am using the same in India. The problem is that I cannot connect to 3g network in india.
I googled and found that MyTouch 4g recognize 1900 MHz frequency as 2g and in India, 3g works on that frequency.
Is it possible to make MyTouch 4g listen for 3g on 1900 MHz? Is it possible thru Radio rewrite or something?

My friend has the same phone. Got it from US and 3g is working with Airtel. Make sure that your sim is 3G ready. If it is old then it wont even search any network when in 3G mode. MyTouch 4g supports 2100 MHz. Airtel and every other 3g operator also uses the same Bandwidth in India. You don't need any radio flashing.

Hi Sagar! Thanks for the reply, I took my friend's sim (which is almost a year old), and tried but no luck , I checked the airtel site and they claim that to use 3g, you do not required new sim, the old one works.
I am really confused!

The myTouch 4G is designed to use on the T-Mobile network with HSDPA 900 / 1700 / 2100
The 3G network in some countries will be different. You should have this frequency to enjoy 3G service.
This is preset in the hardware itself, so can't change by flashing Radio. Try using some other carrier sim cards.
Always remember to ensure the compatibility of the carrier before purchasing the phone.
ummm , probably i got the same problem
im in china and when i connect to 3g network the phone displays 4g icon on the top ....

That's not a problem. myTouch 4G is designed for T-Mobile HSPA+ Network.
If your phone displays 4G icon, it means that you are having an HSPA+ network (speed > 14.2 Mbps)
I think you are on China Unicom network, if yes you can enjoy high speed network same as T-Mobile.

Hi, Thanks for the reply, the carrier that I am using has 3g frequency on 2100 Mhz and as you said, mytouch 4g supports that
HSDPA 900 / 1700 / 2100
so, technically, I should get the 3g service, right?

Technically i think it holds good....may be some other compatibility aspect.
I suggest to use the carrier TATA DOCOMO, since they use the advanced technology of NTT DOCOMO, JAPAN
Go through this Wikipedia link. Try changing the carrier sim until you reach the compatibile one.

Technically you should but may be you are in an area where there is no 3g coverage? Just guessing.

Yeah, manish might be right. Check whether 3g network is there and make sure that in settings->wireless n networks->use only 2g network is unchecked.
it should work. I don't see a prob with the phone as it worls here in Karnataka. Try using vodafone 3g too.

Hey Felix,
Just now I asked my friend (who owns MT4G) about airtel 3G in Ahmedabad. Airtel 3g is not yet deployed there it seems. That's what he told. He is getting 3G here in Bangalore but when he visited he dint get 3g. Vodafone has 3G there I guess.
No issues with phone I guess.
BTW, I am Diana's classmate.

See, world is too small!
Back to the point! My wife has HTC G2 (HTC GSM Hero) bought from India only, she is getting Airtel 3g, and I am not! ,
In any case, I am going to get a new sim card tomorrow, and also, I am going to check 3g service with TATA DOCOMO, as I checked with them and they are providing 3g services on HSDPA 2100 Mhz.
So, let me do these test cases and will let update you!
Thanks,

Read somewhere that Airtel has 900 Mhz band in some circle. It might deploy 3g in that band in some circle where it dint win 2100 Mhz band e.g. Gujarat. Tata Vodafone Idea won 2100 band for Gujarat.
It seems Airtel deployed 3G on 900 MHz band in Gujarat. your wife is getting 3G with the phone which has WCDMA 900/2100 Freq band support. MT4G has WCDMA 1700/2100 but you are not getting 3G. so logical conclusion is Airtel has deployed 3G on 900 Mhz. Try switching to Vodafone/Idea. You will get 3G if this is the case.

The T-Mobile myTouch 4G is designed for band frequency HSDPA 900 / 1700 / 2100
It uses HSPA+ (Evolved High-Speed Packet Access) network of T-Mobile.
Even if it's build with HSDPA technique & a maximum download speed of 14.4 Mbps,
It is termed as 4G not 3.5G because it uses the T-Mobile HSPA+ network (speed upto 42Mbps) all over the U.S.
GET THE FACTS CLEAR BEFORE YOU MAKE A COMMENT ON THIS FORUM
@above, FYI, WCDMA is the Physical layer technique for HSPA or HSPA+. So when u say it is HSPA/HSPA+ network your phone is using WCDMA for phy layer.
PLS DON'T COMMENT WHEN YOU DON'T UNDERSTAND THE POST.

I had already checked on their site. It supports 1700/2100 for HSPA(+) network and doesn't support 900 MHz

Wrong. MT4G doesn't support 900MHz band, only 1700(AWS)/2100. Refer to official HTC or T-Mo specs on their respective sites.
Additional possible reason for not having 3G is - you need the correct APNs entered to get the cellular data working.
Hi Friends,
Finally, getting 3g network (sometimes 3g and sometimes 'H') with Airtel only, I did these things
1) Change the sim card, as my sim card was around 6 years old!
2) On my carrier's site, it is not written that I need to request them to start 3g, but actually, we need to send sms '3G' to them, and then they will enable 3g network
3) I did my network mode to WCDMA only,
Some facts
- Airtel Gujarat 3G runs on 2100 Mhz
So, in nutshell
MyTouch 4g works in India with Airtel 3g network !
Thank you all!
Cheers,
Felix

Haha. I told you to change the SIM at first..
Yeah, even i thought 2100 MHz should be freq as it is the same everywhere else. Plus, I was just thinkinig about 900 because airtel dint get 2100 band for Gujarat. But also read somewhere that it tied up with idea for that frequency. So all in all, all is well.
I know it's an old thread. But incase if someone still looking for clean answer on which handset to buy for indian 2G and 3G neworks.
1. Technically AT&T US should do.
2. It should be having 2100 MHz (MegaHertz) 3G HSDPA (Indian carrier use this band to DOWNSTREAM data on 3G band) + 1900 Mhz (Indian carrier use this band to UPSTREAM data for 3G)
If any one of these (HSDPA 1900 / 2100 MHz) is missing from your mobile handset, Then your 3G will not work in India.
3. 900 and 1800 and 1900 MHz for 2G / EDGE / GSM / GPRS
So in all it should be like this to cover all indian operators
General 2G Network : GSM 900 / 1800 / 1900
3G Network : HSDPA 1900 / 2100

Hello all,
I'm confused a bit. Is the T-Mobile Samsung Vibrant T959 Dualband or Quadband phone. According to T-Mobile web site it's a Dualband. According to XDA it's a Quad Band... Which is it?

I might be wrong but I think it is quadband GSM voice/data.
Tri band 3G, has both T-Mobile 3G bands but only 1 of the At&t 3G bands.

It is Quad band for GSM network (voice, Edge). That means it will work in any GSM network around the World.
It is also Tri-Band for 3G network (1700/2100, 1900, 2100). The first band is the AWS that is used by T-mobile and a few networks in Canada and south America. The second one is used by AT&T in some areas. The last one is used in most Europe, Middle East, Africa, Asia.
