So I have a G2 I was think about getting unlocked, but I wasnt sure of what to excpect. I have read that when unlocked that the G2 is capible of doing 3G on AT&T as well. Can anyone confirm this or not for me? Thanks in advance!
Long answer: even when unlocked, the T-Mobile G2 cannot do 3G on AT&T's network. You need to get the HTC Desire Z from Bell in order for it to have the proper hardware for 3G on AT&T. This is because the G2 lacks the hardware capability of using AT&T's 3G bands.
Short answer: no
As the previous poster said, no it won't get 3G on AT&T.
You'll get EDGE only.

just got my g2 unlocked and edge works fine on it. I know 3g won't work because T-mobile has a proprietary frequency for their 3g....
then it sorta hit me as i was on att's website, would it be possible for me to get att's new hdpa network, or their upcoming LTE?
You do know they make a Desire Z that works with AT&T's 3g network right?

Also I doubt that the G2 will work on any upcoming AT&t 4g network.
... and definitely not LTE. There's no radio for that in the g2.

Okay, so the G2 can have at&t, but how about cricket?
cricket is like Verizon, so no because cricket doesn't support sim cards.

You couldn't hook it up via phone? Like, forget the simcard? Damn
No, you can't. Cricket is a CDMA network. The G2 does not even have the right type of radio hardware to work on CDMA.
Did you buy one already or something?
OP has a lot of posts on this (G2) forum. So my guess he presently has the G2 and is thinking of switching carriers.
The G2 will only work on GSM networks, and might not get 3G on many carriers besides T-Mob (only EDGE).
If you want to go pre-paid with a G2 I think your best bet is Walmart Family Mobile, they are on T-Mobile's network so you should be able to get 3G speeds.

You will only be to access 2G/edge data speeds, no 3G connectivity since AT&T uses different 3G bands.. assuming you are currently using a T-Mobile G2 with the carrier T-Mobile... :?
You won't have any signal issues unless AT&T has horrible coverage where you live.
you will not change anything hardware related... you just unlock/root your phone which allows you to modify hardware and software related things. But if you don't touch the antenna software then nothing will change
@CaliBoyPhillip; when I was in the states my phone switched from AT&T and T-Mobile all the time (roaming) and still had 3g reception, the phone supports most frequencies.
no im currently using a Aria with AT&T but im getting the G2 or the G2X tomorrow. and ok so i wont lose my 3G?

G2x will work with At&ts 3g/4g. As for G2 I was told it doesn't support the 3g/4g from at&t. Remember the buy out isn't final yet.

hmmm Interesting... it was prob due to the reason that you were roaming but if he uses an AT&T SIM on his SIM unlocked G2 from T-Mobile, he won't have 3G access I think... The G2 runs on 850/900/1800/1900 for edge and 1700/2100 radio for 3G data, meanwhile AT&T operates on 850/1900 for EDGE and 850/1900 for 3G.... not compatible !
EDIT: source for the bands ATT uses for 3G gotten from here.. http://www.att.com/gen/press-room?pid=14003

THis is correct. The G2 WILL NOT work with ATT 3G. If you want 3G you need to purchase the NAM (North American Model) of the Desire Z. It is sold in Canada on the Bell Network. You can find it online unlocked and unbranded and it WILL work on ATT no problem. It is going to cost you though, 450-550 depending where you get it.
Same reason iphone won't connect to tmobile 3g...amazing people still don't understand this

Not unless you know how and which chipset to replace on the board. Ie not possible.

Nope, the phone's hardware is what decides what bands it can use.

Get a desire Z from rodgers Canada the 3g bands are the same
To bad radio isn't software
It's to bad that phones don't have the radio frequencies programmable in software (much like an fm radio). Is that even possible?
or does the wifey need to buy a cheapo when she goes to the states next year?
Yes its quadband

It would help if you say what model number/versions you are talking about. The Euro DZ (or just about any model DZ, I think) has the GSM bands to operate on the two major US GSM carriers, AT&T and T-Mobile. As long as your phone is not SIM locked, you will have voice and EDGE data. But you will not get 3G data.

I know my US g2 got 3G (or 4G? HSDPA+) in Poland. I have US T-Mo G2 on AT&T with only EDGE. And it should work on either AT&T or T-Mobile.

It won't get 3G on both. As you've said it'll either get 3G on AT&T or T-mobile.
The Bell (Canada) DZ will get AT&T 3G. Other models will get 3G on T-mo.

I have CM7 loaded, but doesn't really matter what rom I load, I can't seem to get 3G data speeds. I am getting internet, so that tells me the APN is setup correctly, just not 3G. Any thoughts?
Jason
probably need to look into a different radio
Any ideas? I tried 3 different ones!

The model I have is A7272 and I have an AT&T sim. Do you think the sim tells the phone what band to use for 3G? They have the option of a T-mobile sim, does anyone think that will work?
look up the A7272 on gsm arena to see what 3G band it supports and cross reference it with ATT's 3G band
Sent from my Desire Z via XDA App
I think it was because I had an ATT sim. I got a T-mobile sim and now I'm getting "H" everywhere. Still doesn't seem as fast as Verizon's 3G, but for $45/month I can't beat it. So the A7272 supports HSDPA 900 / 2100, is that why with the T-Mobile sim I can get H, because they have a 2100 HSDPA Frequency?
AT&T uses the 850/1900 spectrum for 3g and the 700mhz spectrum for 4g.
Since your phone supports none of those, that's why.
T-Mobile uses 1700/2100 (requiring both) or 1900 for 3g/4g. now, you only have half of the 2 spectrum requirement so you probably only have "half" 3g. Tmobile uses one spectrum for upload and one for download. I don't know which one is which, but if you only have one, that means you'll only get 3g/4g speed on either uploads or downloads, but not both.
I guess I fell into this trap as well... I bought a desire z thinking I could use 3g on it with my ATT/Straight talk sim. After unlocking and re-roming, I now see the same issue, stuck on Egde, and really slow edge at that.
jch2os, did you see a difference in your service area/call quality switching to the tmobile sim? I've been really happy using an Inspire on Straight talk with ATT's network, do you feel the tmobile service is a downgrade from what you previously had with ATT/Straight talk?
Thanks for the info!
After some research via eBay and Amazon, it turns out that there is two versions of the Desire Z. There is the A7272 which supports the WCDMA 900/2100 MHz bands and the A7275 which supports the 3G 850/1900 MHz bands.
idenlover, if your device is getting EDGE on the Straight Talk sim that runs on AT&T's bands, your device is the A7272 and you should get the T-Mobile Straight Talk sim. I myself am a G2 user on T-Mobile and I can say service and calling is pretty much crystal clear except in school, where there are numerous concrete buildings. Then again, I'm based in Miami, FL so I wouldn't know how service would be on your end. I hope this helps!
if you want AT&T you need the A7275 from bell canada.
Hi all! Look like i have the same problem. I have Desire Z from Russia - with russian symbols in a hard-keyboard. And in FIDO network i have only EGDE signal - never 3G. My question: what a part of phone i need change? Antenna? GSM-module? or something other? Please don't advice me change the phone - i need this keyboard, with russian symbols!!! )
P.S. If anybody know solution this problem in software (any radio, ROM, or etc.) - please, answer me too. I don't want a lot open the phone and change any parts, only if this really needed. )
P.P.S. If it important - my h-boot is 0.84.2000.

From what I get from your problem is that your phone doesnt support the FIDO network 3g bands. I think that is hardware locked. Hopefully somebody can chime in
