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.

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.

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!

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.

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

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.

The 2100 frequency should work on 3G worldwide, right? I also asked a representative in chat if the Streak will be sold unlocked on their website and the answer is "we don't know yet, check back when the product is actually on the market".
I did not know what was exact, until I read this below
http://www.streaksmart.com/2010/07/dell-streak-with-tmobile-3g-bands-out-in-the-wild.html
I'm sorry if I am repeating information, but I thought I would explain in case anyone else was wondering.
UMTS/HSDPA/HSUPA are 3G technologies, so yes its defintiely 3G.
The 2100 MHz support should help the dell Streak work in countries other than the US and on networks other than AT&T. BUT, keep in mind that this will not work with T-Mobile's 3g network.
T-mobile uses 1700/2100, but the 2100 here on the dell shouldn't help much, because the 2100 is used for downloading while the 1700 band is used for uploading, and I'm pretty sure you can't use 3G download without 3G upload connected too. So if a carrier outside the US has a similar setup as T-mobile USA, with the split upload and download bands, then you could find yourself without 3G on that network too.
I would like to know if this version work 3G with T-mobile US , i want to get it from clove.co.uk but i want to make sure first if it works with T-mobile US 3G ....
Thanks
clove sell them with 3g frequencies of
3G Network - HSDPA 900/1900/2100
t-mobile usa uses 3g on
1700 and 2100
so you would be missing a band, doubt it would be any good for you.
no 3G without the 1700 band
tmo usa uses 1700 upload and 2100 download - i foolishly thought i could survive with just 3G on the download side - luckily someone that had tried it with a HTC Desire from Tmo UK told me it didn't - if tmo usa network doesn't see both sides of the AWS IV band (1700 & 2100) it will limit the connection to 2G speeds

that's why they call it a "band". Without both frequencies that are bound together, it aint gonna work.

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.
Sent from my Liberty using Tapatalk
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.
I am planning to buy MT4G, unlock it and use it on another carrier with compatible frequencies of course. Will I be still able to get updates using for example a wifi connection? or should I download updates manually? Is there something that I will lose when I use the phone on another carrier ?
I don't know if you mean overseas or in any place other than the U.S. but the only "compatible" carrier for this phone besides T-Mobile is AT&T. The reason why compatible is in quotes is because yes the phone would function and make calls on that network, but you will lose 3G and HSPA+ service as AT&T's equivalents operate on a different and incompatible spectrum.
I would also assume that you would not receive OTA updates either.

I don't know for absolute certain, but I'm 95% sure you wouldn't recieve OTA since it goes out over the network your phone is connected to.
You can usually snag the update from here, but unfortunately, a lot of people didn't run aLogcat to log the download and get the link. Including myself, though I'm trying now with my second device.

Another question, does anyone know if this device works on UMTS band I 2100 ( 2100/1900)? I really can't make up my mind because it's not clear on T mobile website. It says UMTS 1700/2100/AWS and this looks like it's referring only to UMTS IV

The phone is compatible with almost every gsm band the specs are:
GSM 850 / 900 / 1800 / 1900
HSDPA/HSUPA 900 / 1700 / 2100
In the US most carriers are using GSM 850/1900 and 3G 1700/2100 you will only get OTA from T-mobile in the US if you are using their cellphone service or you can hope and wait for the update to show up here on XDA in the forum.

so you should have no problem using 3G or even 3g+ "4G" on this phone if your cell provider offers it. But it may require an advanced sim card or signing up for a special data service.
Dont get confused by the various terms (UMTS EDGE HSPA etc.) a phone that is guad-gsm and tri-3G will run the data services just fine but T-mobile will tell you we dont guarantee the data capabilities outside of our network... because they dont want lawsuits

The phone is compatible with almost every gsm band the specs are:
GSM 850 / 900 / 1800 / 1900
HSDPA/HSUPA 900 / 1700 / 2100
In the US most carriers are using GSM 850/1900 and 3G 1700/2100 you will only get OTA from T-mobile in the US if you are using their cellphone service or you can hope and wait for the update to show up here on XDA in the forum.

Actually I am a telecom engineer so I know about the terms. You didn't get my question about the bands. Look here for example support.t-mobile.com/doc/tm24233.xml?&A2L.SERVICE=FeatureSummary
The listed Bands: 1 (2100) and 4 (AWS 1700/2100)
and that clearly shows that G2 supports 2 UMTS bands , 1 and 4
1 is 2100 paired with 1900 ( EU)
4 that is used by T mobile in the US.
So I am confused because on this page mytouch.t-mobile.com/mytouch-4g-features#/specs-and-manualsthey listed the bands like this
Bands 1700/2100/AWS that's why it's not clear for me if MT4G supports UMTS I or not.
This is the official reply from HTC when asked:
Dear ....,
I understand that you would like to know if your T-mobile Mytouch 4G device can use the 2100 MHZ band over in Europe for 3G. I do apologize your device is not compatible with the 2100 MHZ back over in Europe for 3G service. I do apologize for all the inconvenience that this may cause you.
To send a reply to this message or let me know I have successfully answered your question log in to our ContactUs site using your email address and your ticket number .....
Sincerely,
Victor
HTC

AWS is the data delivery method used only by Tmo in the US. So the 4G service may not work outside the US but according to the phone specs it states that it supports UMTS and GPRS/EDGE so it should support 3G UMTS/HSPA/HSPA+ and gprs/edge for 2G everywhere. Ill test my HD (from England) when I get to new york in a day or so and see if I can get proper 3G speeds.
Todays smartphones are designed to be used worldwide with full service as much as possible.
AWS is just another name of UMTS band IV. This is the only UMTS band the MT4G supports, so you'll be able to use it for 3G on carriers that use this band. You can see the list of bands and operators that use them here:
http://en.wikipedia.org/wiki/UMTS_frequency_bands
In short, outside of the US, Canada, and Chile you're out of luck for 3G. You'd be able to use 2G fine though.

Frequency bands differ for different technologies on the same phone. For example there are 2 versions of Nexus one one for ATT and one for T mobile although they work on GSM level because the support both GSM bands on T mobile and ATT but not the UMTS bands on both networks. UMTS and GSM frequencies are not necessarily the same for each network and most probably they won't be the same. In my country we licensed 3G services ( UMTS) on 2100 band or UMTS 1 . GSM on 900 and 1800 only.
Can someone provide me with the FCC id from the back of the phone ?
I tired to search for it on the web but I don't think what I found was the correct one.
Update
I went to T-mobile store today, the guy was helpful and he printed out the official full technical specifications for the device that he pulled out and here what I got:
3G/UMTS Bands
Band I / UMTS2100 Yes
Band II / 1900 No
Band IV 1700/2100/AWS Yes
Band V/850 No
Band VII/ 900 No
The page was titled " Enablers" and listed specs for GSM and UMTS bands with their features. So I think this ends it for me, it does support both bands I and IV.

Did it work with you in 3G speed in England ?
Good luck but I've taken my nexus one all over the planet... you'll get 3g in the countries listed above plus Japan (softbank only) but I haven't gotten 3g anywhere else....

I am planning to buy MT4G, unlock it and use it on another carrier with compatible frequencies of course. Will I be still able to get updates using for example a wifi connection? or should I download updates manually? Is there something that I will lose when I use the phone on another carrier ?

@OP: have you gotten the MT4G to work with UMTS Band I frequencies?
I got the update by only using my friend's t-mobile sim card, I think I got it via wifi since he doesn't have data plan.

I don't know if you mean overseas or in any place other than the U.S. but the only "compatible" carrier for this phone besides T-Mobile is AT&T. The reason why compatible is in quotes is because yes the phone would function and make calls on that network, but you will lose 3G and HSPA+ service as AT&T's equivalents operate on a different and incompatible spectrum.
I would also assume that you would not receive OTA updates either.
