I hope someone can answer me this question, please. I want to hopefully understand something before I purchase a Blackstone. My phone carrier is AT&T, and I live in an area that has 3G coverage. Supposedly this area also has HSDPA. I understand already that the HD will not work on AT&T's 3G, but will it work on the HSDPA? I *think* that HSDPA would be fast enough, yes? I tried to look this up, but I am not 100 percent sure of what I am reading... please all, forgive that I didn't understand enough to figure this out myself. Is there someone out there who also has this carrier and can verify that I will be able to surf faster than EDGE? I want to eventually use the secondary camera of the device to make video calls - I have Deaf family members who can be contacted by videophones and I want to do that some day with the HD!! Any and all help is apprecated.
u prolly have your answer by now, but i can fill in here...
HSDPA will work... i have an experia that won't say3G, but does say H and i'm getting speeds of 1100kbps which is 3G speeds... so you are good to go on that part...
As for video calling... you won't get it... i'm not gettin it at all even tho i have modified my phone for it to work... its an AT&T thing... apparently they maybe supporting it in the next few months (so i've read)... knock on wood cuz that would be ground breaking for the USA
HSDPA will not work. HSDPA is a form of 3g (HSDPA/HSPA/UMTS). The HD does not support At&T or any other US carrier 3g frequencies. You will have EDGE

technically, neither does the x1i i have... but in the discription it does say 850/900/1800/1900 for both phones...
and my phone does not say E... it says H... the hardware are almost identical between the 2 phones...
there were alot of naysayers about the x1i and 3g speeds... but when i got it, popped in the sim card... my internet was BLAZING....
Connectivity: Quad-band GSM/GPRS/EDGE: 850/900/1800/1900 MHz
WCDMA / HSPA: 900/2100MHz. HSDPA 7.2 Mbps
as you can see, the HD supports 3g on 900/2100 (which US networks do not operate 3g on). Although 850 is a 3g frequency for at&t, the HD does not search for HSDPA on that frequency and only for EDGE and, therefore, you'll only get EDGE
Svegetto is correct. I have the HD and I am on AT&T. All I get is the big E. It is faster than it used to be, but it is still Edge.
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.
Thanks guys for the answers. I really like this phone but I don't want to get the one in tmobile, because I want Arabic support and I don't know if vibrant accept I900 0 Roms . If it does of course I will get it . So my q now is the vibrant accept I9000 roms or not ?
Thanks again

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.

Overseas, on a network that is compatible with regard to GSM/ UMTS frequencies. So the only way to get updates is to download them from forums like this one?

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.
http://www.worldtimezone.com/gsm.html
In Israel where I am, and England, France and Germany etc. the bands are
2G 900/1800 and 3G 2100
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

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.

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.

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.

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.

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.

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

I was wondering why I can only get EDGE on my TMobile G2 phone... is it because of the GSM incompatibility that some TMobile phones have with the ATT network or am I doing something wrong?
Does your phone support 1900 MHz UTMS? That would be a problem. If it does then use *#0011# and make sure the bands are unlocked.

I got "connection problem or invalid MMI code" when I ran that.
Edit: Did a bit more research and it turns out that it does *not* support 1900 MHz UTMS for 3G, so basically, this phone + ATT network = no 3G service, as the hardware is incompatible.

Someone doing their own research? Get the hell out.
Actually, I don't think the G2 even does 3G on anything but AWS. The HTC Desire Z (identical but without carrier branding) has a version that supports AT&T 3G, however.

Can you explain what you mean by "use *#0011# and make sure the bands are unlocked"? My Samsung phone can't get 4g service here on T-Mobile and it doesn't do 3G so I'd really like to enable HSPA+ if that's possible. I don't see anything on that screen that I can unlock though.

Check which UMTS (3G) bands your phone supports - I suspect yours does not support T-Mobile's 3G band (IV). The information is usually available on wikipedia or gsmarena.
You do not "enable" 3G through software changes. Your phone supports it or it doesn't.

It does support band IV, 1700Mhz, but it doesn't do HSPA+ so it can't get 3G. That screen still doesn't tell me anything though.
GSMArena says it has 3G Networking on HSDPA 850 / 1700 / 2100 / 1900 but that's not true. There is no 2100Mhz band, not on mine anyway. Actually GSMArena isn't very complete or very accurate, it don't even list the model T959V!

That's not how HSPA+ works - it's essentially just faster 3G. Also, I found your phone on GSMArena, not sure how you searched but the information is all there and it supports band IV (1700/2100) and I (2100).
Are you sure you've enabled 3G (or deselected "Use only 2G networks")?
What is the history of the phone (bought new, used, etc.)? It should "just work" on T-Mobile as it's T-Mobile branded but, no offense, your details are a little vague.

Sorry if I was vague but it doesn't "just work" on T-Mobile! At first I though all Exhibit II models would be the same however they could have different versions like the Galaxy 2 that has an older version for 3G and a newer version that also now gets 4G, who knows.
The phone was purchased new a few months ago and is still stock. I know HSPA+ is faster 3G since I can get it on 1700Mhz on another device using the T-Mobile SIM from the Exhibit 2. Can't get HSPA+ or 3G on the Exhibit 2 though.
Yes the phone is on GSMArena but the info is not accurate, it claims the phone gets 3G and has a 2100Mhz band but that's not true. It only supports band IV on 1700.
There is no option to enable 3G or "Use only 2G networks". It has options for WCDMA (for 4G on 1700) or GSM (for Edge on 1900) but there is no setting in between for 3G or HSPA+. I tried setting it to WCDMA only but it defaults back to Auto using Edge unless I go to a T-Mobile store where they have a strong 4G signal that gives 5 bars. If I leave the store and go down the street there's no signal though.
I have verified that WCDMA for 4G is on 1700 and GSM for Edge is on 1900 using a spectrum analyzer but it never uses 2100 and has never used 3G anywhere in the Phoenix, Mesa or Scottsdale area, just Edge. There may be other modes and frequencies but I haven't been able to verify them.
If there is a way to turn on 3G I'd like to know what it is? Someone suggested dialing *#32489# clicking #3 then UTMS but that didn't do anything.

I don't know where to begin but let me get this straight...
-You bought a new Exhibit II from T-Mobile.
-It doesn't get 3G outside of the store.
-Your other T-Mobile compatible device gets 3G outside of the store.
-You've owned this same Exhibit II which hasn't been connecting to 3G for months.
On these points alone, am I understanding you correctly?

Close but not quite correct, it doesn't get 4G outside of the store.
It can't get 3G at all anywhere!
Since there is no 4G network is there a way to turn on or enable 3G or is it hopeless?

In a previous post you said that you "know" what I'm talking about but clearly that is not the case.
What T-Mobile calls 4G is actually 3G with improvements to the backhaul as well as the radios on the phones - where T-Mobile has 4G, it also has 3G.
The point of my last post was to make it obvious that you have a defective phone. I shouldn't have assumed you would figure it as you haven't figured it out in the months you've owned a phone that obviously has reception issues.

Again not true! What they call 4G is using WCDMA but 3G is using HSPA+. 3G using HSPA+ has improvements that will allow it to go up to 20Mb but my Android phone doesn't have an option for 3G, just 4G using WCDMA. The people at the T-Mobile stores would beg to differ with you about the phone being bad since I've been to 5 T-Mobile stores and they say the phone works OK since it can get 4G on 1700Mhz in the store.

Your posts are too long to be trolling, but it still feels like you are because everything you post is wrong.
In case you're not trolling:
-Your phone has hardware defects that are affecting how well it connects to 3G.
-The fact that you get reception in stores is likely because stores have signal boosters.
-Retail employees are idiots. They are trained to use the products just enough to sell them (read: not much) and aren't paid enough to attract anyone with half a brain to the position. Walk a block away from the store and show them that your phone doesn't connect to 3G (or "4G" if you still want to call it that).

Both of you are feeling like you're trolling.
It may be a tower issue or your phone. The only way to check is to use another phone.
